1. Why Honda Owners Benefit from Permanent Ceramic Protection

Honda has built its global reputation on engine longevity. The brand's engines have a documented track record of crossing 250,000-400,000+ miles when properly maintained, and the Honda community treats high mileage as a feature rather than a liability. Civic owners with 300,000+ miles on the original engine post photos to Reddit r/civic and HondaTech regularly. Accord drivers with 400,000+ miles aren't unusual. The legendary Honda Odyssey and Pilot J-series V6s routinely cross 250,000-350,000 miles. The S2000 community considers a 200,000-mile F20C engine to be middle-aged.

That ownership philosophy aligns directly with Cerma's value proposition: a one-time investment that protects the engine permanently. Honda owners are already wired to think about engine longevity. The same Honda owner who religiously changes oil every 5,000 miles for 20 years to keep their CR-V running understands engine maintenance as the long game. Cerma fits naturally into that mindset.

Honda vehicles also have specific engineering characteristics that make Cerma especially relevant:

• VTEC and i-VTEC variable valve systems. Honda's VTEC technology uses two camshaft profiles - one for low-RPM efficiency, one for high-RPM power - actuated by oil pressure switching the rocker arm engagement. The lost-motion assembly and rocker arm contact surfaces benefit significantly from Cerma's friction reduction, particularly on tuned K-series engines that spend more time at high RPM.
• The modern Honda lineup is dominated by turbocharged engines. The L15B 1.5L turbo is the volume engine across Civic, CR-V, HR-V, and older Accord. The K20C1/K20C4 2.0L VTEC Turbo is the performance engine in Type R, Integra Type S, RDX, TLX, and older Accord 2.0T. Turbocharger bearings at 50,000-200,000+ RPM are exactly the wear surface Cerma's bonded ceramic protects best.
• Honda's K-series tuner community is significant. K20A2, K20A, K24A2, K20C1 - all have major aftermarket support, and K-swaps into older Civics, CR-Xs, and Integras are common. Tuning increases bearing loads, valvetrain stress, and turbo bearing wear (where applicable). Cerma's ceramic protection scales with the loads it's protecting against.
• Honda's e:HEV hybrid system uses gasoline engine oil normally. The Civic Hybrid, CR-V Hybrid, Accord Hybrid (and older Insight) gas engines benefit from Cerma identically to their non-hybrid counterparts - and the start-stop hybrid operation creates more cold-start events than non-hybrid engines, which is exactly when bonded ceramic protection matters most.
• J35 V6 timing belt service is a known maintenance milestone. Pilot, Passport, Ridgeline, Odyssey, and Acura MDX use the J35 V6 with a timing belt requiring replacement around 105,000 miles. Cerma applied at the timing belt service is excellent investment maintenance for engine internals going forward.

Cerma STM-3 is fundamentally different from any oil or additive. The active ingredient is Nano Silicon Carbide (SiC) - actual ceramic particles that bond mechanically to engine metal surfaces over the first 3,000 to 5,000 miles of driving. Once bonded, the ceramic creates a sacrificial wear layer between metal-on-metal contact points. Friction drops by up to 90 percent. Wear slows dramatically. And because the bond is mechanical, the ceramic survives every oil change.

For more on the underlying chemistry, see our complete guide to Nano Silicon Carbide. To understand the EPA ETV certification that backs Cerma's performance claims, see our guide to EPA Environmental Technology Verification.

2. Which Cerma Product for Your Honda Engine

Whether you're treating a 2026 Civic Type R with the K20C1 or a 2002 Civic Si with the K20A2, the Cerma application is the same: 2oz gas treatment ($105.60), one bottle, one-time application.

3. Special Note: VTEC and i-VTEC Compatibility

Honda's VTEC (Variable Valve Timing and Lift Electronic Control) technology is one of the most distinctive engineering features in the automotive world. Introduced in 1989 with the B16A, refined through the i-VTEC era starting in 2001, and continuously developed through the K20C1 currently powering the Civic Type R, VTEC has been a defining Honda differentiator for over 35 years. Understanding how VTEC works clarifies why Cerma's friction reduction is particularly valuable on Honda engines.

How VTEC works

A traditional engine uses a single camshaft profile - one set of cam lobes that determines valve lift and duration regardless of engine speed. This forces a compromise: cam profiles optimized for low-RPM efficiency limit high-RPM power, while profiles optimized for high-RPM power create poor low-RPM driveability and emissions.

VTEC solves this by using two different camshaft profiles on the same camshaft. At low RPM, normal rocker arms ride on a "primary" cam lobe optimized for efficiency. At a programmed RPM threshold (typically 5,200-6,000 RPM on naturally-aspirated engines, varies on turbo K-series), oil pressure activates a hydraulic pin that locks the rocker arms together, engaging a secondary "high-lift" cam lobe with greater valve lift and longer duration. The result is the famous "VTEC kicked in yo" engagement that K-series and B-series enthusiasts have celebrated for decades.

i-VTEC adds variable valve timing

The "i" in i-VTEC stands for "intelligent" - i-VTEC adds Variable Timing Control (VTC) on top of the lobe-switching mechanism. VTC continuously varies camshaft phase (the timing of valve events relative to crankshaft rotation) using oil pressure to actuate a hydraulic phaser at the front of the camshaft. The combination provides both variable timing AND variable lift/duration, optimizing the engine across the entire RPM range.

Why Cerma works particularly well on VTEC engines

VTEC and i-VTEC create specific wear surfaces that benefit from Cerma's permanent ceramic bond:

• Rocker arm contact surfaces. Both the primary and secondary VTEC rocker arms ride on cam lobes constantly. The lost-motion assembly (the third rocker arm that follows the high-lift lobe even when not engaged) sees particularly high cyclic loading.
• Cam lobe surfaces. The high-lift "VTEC lobes" only engage at high RPM, but when they do engage, they apply significantly more valvetrain force than the primary lobes. Tuned K-series engines that spend more time at high RPM accelerate cam lobe wear.
• VTC phaser internals. The variable timing actuator uses oil pressure to rotate the cam phase. The internal vanes and seal surfaces experience constant friction during operation.
• The hydraulic VTEC engagement pin. The locking mechanism that engages secondary rocker arms slides under oil pressure thousands of times per minute when VTEC is active.

Cerma's bonded ceramic creates a sacrificial wear layer at every one of these contact surfaces. The mechanical bond doesn't interfere with VTEC's oil-pressure actuation - Cerma doesn't change oil viscosity, oil flow rate, or oil pressure. The VTEC system continues operating exactly as Honda designed it, but with friction reduction at every contact surface.

Many K-series owners report that VTEC engagement feels notably smoother after Cerma application - the transition between primary and secondary cam lobes becomes more refined, and the high-RPM operation feels less mechanically harsh. This is particularly noticeable on tuned K-series engines that spend significant time above the VTEC engagement RPM.

4. Special Note: K20C1 Civic Type R - The 158 hp/Liter Masterpiece

The K20C1 currently powering the Civic Type R (FK8 generation 2017-2021, FL5 generation 2023-present) and the Acura Integra Type S is one of the most engineering-impressive 4-cylinder engines ever sold in North America. From 1,996 cc, Honda extracts 315 horsepower at 6,500 RPM and 310 lb-ft of torque from 2,600-4,000 RPM. That's 158 hp per liter - territory previously reserved for race-spec engines.

The 2026 Civic Type R holds the front-wheel-drive Nurburgring lap record at 7:44.881 - a time that puts it ahead of many naturally-aspirated supercars from a generation ago.

K20C1 engineering details that benefit from Cerma

• Lightweight die-cast aluminum open-deck cylinder block with cast iron cylinder sleeves and reinforced main bearing caps. The cylinder walls have plateau honing for better oil retention.
• Forged steel crankshaft with micro-polished journals specifically engineered for friction reduction. Cerma's bonded ceramic adds another layer of permanent friction reduction at these journal surfaces.
• Heat-forged high-strength steel connecting rods for handling extreme cylinder pressures.
• Lightweight pistons with cavity-shaped crowns and a low-friction molybdenum coating applied in a dot pattern - Honda specifically engineered these pistons for friction reduction.
• MHI TD04 mono-scroll turbocharger with electric wastegate, producing 22.8 psi of boost at peak. The turbo bearings spin at extremely high RPM under load.
• Direct fuel injection for precise fuel metering and combustion cooling.
• Variable Timing Control (VTC) on both camshafts plus VTEC on the exhaust cam.
• Sodium-filled exhaust valves to conduct heat away from valve faces (a feature usually reserved for race engines).

Why Cerma is particularly valuable on the K20C1

The K20C1 is engineered for friction reduction from the factory - Honda's micro-polished crank journals, molybdenum-coated pistons, and plateau-honed cylinder walls all exist to reduce friction. Cerma's permanent Nano Silicon Carbide bond adds another layer of friction reduction on top of Honda's factory engineering, particularly at:

• The turbocharger center bearings that spin at high RPM under continuous boost
• The crankshaft main and rod bearings already micro-polished from the factory
• The cylinder walls where the molybdenum-coated pistons ride
• The VTEC-equipped exhaust cam lobes and rocker arms that experience high-load engagement at peak RPM

For tuned K20C1 owners (Stage 1, Stage 2, big turbo builds in the 400-600+ wheel horsepower range), the value proposition strengthens further. Higher boost = higher cylinder pressures = more friction at every wear surface. Cerma's protection scales with the loads it's protecting against. The K-series tuner community on K-Tuned, Drag Cartel, ICY Performance, Hondata, KTuner, and other tuner platforms increasingly recognizes Cerma as preventive maintenance for high-output K-series builds.

5. Special Note: L15B 1.5L Turbo - The Honda Workhorse

The L15B 1.5L turbocharged inline-four is the volume engine across the modern Honda lineup. It powers the Civic (since 2016), CR-V (since 2017), HR-V (since 2023), and older Accord 1.5T (2018-2022). Variants of the L15B also serve as the gasoline engine in Honda e:HEV hybrid applications. Power output ranges from 174-205 hp depending on tune and application.

For Cerma application, the L15B is straightforward: 2oz gas treatment ($105.60). But there are L15B-specific considerations worth understanding.

L15B oil dilution honest disclosure

If you've spent time on Reddit r/civic, CR-V Owners Club, or HondaTech, you've seen the discussions about L15B oil dilution. Some L15B applications - particularly those driven primarily on short trips in cold weather without reaching full operating temperature - have shown elevated fuel content in the engine oil. Honda issued a Customer Service Update on the affected vehicles, and the issue was traced to the engine's direct injection system combined with cold-weather short-trip operation patterns.

Cerma cannot fix oil dilution. Oil dilution is a condition where unburned fuel makes its way past the piston rings into the oil sump - typically because the engine doesn't reach operating temperature long enough to evaporate the fuel back out through the PCV system. The mechanism is fundamentally a combustion and operating-pattern issue, not a friction issue. Cerma protects against friction-related wear, not oil dilution.

What Cerma does help with on L15B engines:

• Bonded ceramic protection at cylinder walls - particularly important since oil dilution can reduce the protective oil film thickness at the cylinder walls during the period before fuel evaporates back out
• Turbo bearing protection - the L15B's small turbocharger spins at high RPM
• Bearing protection throughout the rotating assembly
• Cam lobe and valvetrain protection for the i-VTEC system

For L15B owners, the right approach is to follow Honda's recommendations on oil change intervals (which are shorter than the 7,500-10,000 mile interval Honda originally recommended for the L15B), drive long enough to reach full operating temperature regularly, and apply Cerma for permanent friction protection. Cerma is preventive maintenance for the engine internals; it is not a substitute for proper warm-up procedures and appropriate driving patterns.

6. Special Note: Honda e:HEV Hybrid System

Honda's e:HEV (Electric Hybrid Vehicle) system represents one of the most sophisticated hybrid architectures in the industry. Found in the Civic Hybrid, CR-V Hybrid, and Accord Hybrid (and the older Insight), e:HEV uses a series-parallel hybrid configuration that's mechanically distinct from Toyota's i-FORCE MAX or Wrangler 4xe approaches.

How e:HEV works

The e:HEV system uses an Atkinson-cycle gasoline engine paired with two electric motors (one drive motor, one generator/starter motor) and a small lithium-ion battery. At low speeds and during cruising, the gasoline engine acts primarily as a generator - it spins to produce electricity that powers the drive motor, while the wheels are driven entirely by the electric motor. At highway speeds, a clutch engages to provide direct gas-engine drive for efficiency. At high power demand, both the gas engine and electric motor work together to drive the wheels.

The result is a hybrid that often operates as a "series hybrid" (gas engine generates electricity, electric motor drives wheels) at low speeds and a parallel hybrid at higher speeds. Honda claims combined fuel economy of 49 MPG city / 47 MPG highway / 48 MPG combined for the 2026 Accord Hybrid - among the best non-plug-in hybrid efficiency in any midsize sedan.

Cerma application for e:HEV

Use the 2oz Cerma gas treatment ($105.60). The gas engine in e:HEV applications is treated like any other Honda L15B or 2.0L engine. The hybrid components - electric motors, lithium-ion battery, inverter electronics - are sealed systems that don't share oil with the gas engine. Cerma doesn't reach them and doesn't need to.

Why Cerma works particularly well on e:HEV gas engines

The e:HEV gas engine experiences a different operating pattern than non-hybrid engines:

• Frequent start-stop cycles. The gas engine starts and stops dozens of times per drive as the system transitions between EV mode, series hybrid mode, and parallel hybrid mode. Each start is a brief moment of low oil pressure when bearing wear is concentrated.
• Cerma's bonded ceramic remains in place even when the engine isn't running. The protection is mechanical, not oil-suspended. This means restart protection continues from the very first moment the engine spins back up, before the oil pump fully repressurizes.
• Atkinson-cycle thermal characteristics. Atkinson-cycle engines have different thermal behavior than Otto-cycle engines, with longer expansion strokes and different cylinder wall temperature gradients. Cerma's heat tolerance (Mohs 9.5 hardness, 2,730 degree Celsius melting point) far exceeds anything any production engine produces.
• Higher RPM operation in series hybrid mode. When the gas engine acts as a generator, it can run at higher steady-state RPMs than typical cruising operation. Cerma's protection is constant regardless of RPM.

Many e:HEV owners report that Cerma's friction reduction in the gas engine portion compounds with the existing hybrid efficiency - improving overall fuel economy in hybrid driving mode and providing smoother gas-electric transitions.

7. Special Note: J35 V6 - The Family-Hauler Engine

The J-series V6 has been Honda's volume V6 engine since 1996, and the J35 displacement variant has been continuously produced since 2003. It powers the Pilot (since 2003), Odyssey (since 2005), Ridgeline (since 2006), Passport (since 2019), Acura MDX (since 2003), and Acura TLX V6 (2014-2020). Power output ranges from 240-310 hp depending on the specific J35 variant and application.

The J35 is one of Honda's most-produced engines in history and has a documented track record of reliability. With proper maintenance, J35-powered vehicles routinely cross 250,000-350,000+ miles. The J35 has appeared on dozens of "most reliable engines" lists from automotive publications.

J35 timing belt service - the critical maintenance milestone

Unlike most modern engines that use timing chains, the J35 V6 uses a timing belt requiring replacement at approximately 105,000 miles (or 7 years, whichever comes first per Honda's recommended service interval). This is significant because:

• The J35 is an interference engine. If the timing belt breaks, the pistons collide with the valves, causing catastrophic engine damage requiring head work or complete engine replacement.
• The timing belt service is significant labor. The job typically costs $800-$1,500 at an independent shop or $1,200-$2,000 at a Honda dealer, including water pump replacement (which is driven by the timing belt and should be replaced at the same time).
• Skipping the service is the most common cause of catastrophic J35 failure. Search "J35 timing belt failure" on any Honda forum and you'll find owner reports of $5,000-$8,000 engine replacement bills from skipped timing belts.

Cerma timing for J35 owners

The optimal time to apply Cerma is at the 105,000-mile timing belt service. Why?

• Fresh oil. The timing belt service requires oil change anyway as part of the comprehensive service.
• Engine has just received major preventive maintenance. Adding permanent ceramic protection at the same time leverages the maintenance investment.
• Going forward, the engine has both fresh timing components AND permanent friction protection. Combined, these set up the engine for the next 100,000-150,000+ miles.

For J35 owners who haven't yet hit the 105,000-mile mark, applying Cerma at any earlier oil change is also fine - the ceramic bonds during the next 3,000-5,000 miles of driving and stays through every future service. The earlier in the engine's life Cerma is applied, the more wear is prevented over the engine's total lifespan.

VCM (Variable Cylinder Management) honest disclosure

Some J35 V6 applications (Pilot, Odyssey, MDX) use VCM (Variable Cylinder Management), Honda's cylinder deactivation system. VCM deactivates 3 cylinders during cruising to save fuel. Some VCM-equipped J35 owners report excessive oil consumption and ringland wear on the deactivated cylinders, particularly on 2008-2013 Pilot and Odyssey applications. Honda issued an extended warranty for affected vehicles, and many enthusiasts disable VCM via aftermarket "VCM Muzzler" devices to prevent the issue.

Cerma cannot reverse existing VCM-related ringland wear or oil consumption (those are mechanical issues requiring ring replacement). For J35 owners running healthy engines or with VCM disabled, Cerma is excellent investment maintenance against the cylinder wall wear that contributes to ring sealing issues over time.

8. Special Note: K-Series Legacy and the F20C S2000

The Honda K-series (introduced 2001) and the F-series F20C/F22C1 used in the S2000 deserve their own discussion because of the cult enthusiast following these engines have generated.

K20A2 / K20A / K24A2 - the legendary K-series

The K20A2 (2002-2006 RSX Type-S, JDM Civic Type R), K20A (JDM Integra Type R DC5), and K24A2 (Acura TSX, K24-swap legends) are among the most-modified naturally-aspirated engines in tuning history. Forced induction K-swaps producing 600-800+ wheel horsepower exist by the thousands. Naturally-aspirated K-series builds (cams, ITBs, headers, displacement) producing 250-350+ wheel horsepower are common at Honda meets.

For K-series swap owners and high-RPM build owners, Cerma is ideal preventive maintenance. The K-series valvetrain spins to 8,000-9,000+ RPM in many tuned applications - exactly where friction reduction at the rocker arms, cam lobes, and lost-motion assemblies provides the most measurable benefit. Apply 2oz gas treatment ($105.60) at any oil change. The ceramic bonds during normal driving and stays through every future service.

F20C / F22C1 - the S2000 legend

The F20C (2000-2005 S2000) and F22C1 (2006-2009 S2000) hold a unique place in automotive history. The F20C produced 240 hp from 2.0 liters - 120 hp/liter, the highest specific output of any naturally-aspirated production engine when it was introduced. The F22C1 (an evolution with longer stroke) produced 237 hp from 2.2 liters with improved low-end torque.

The S2000 famously redlines at 9,000 RPM. The engine is hand-assembled with race-quality components throughout: forged crankshaft, forged connecting rods, lightweight pistons, oil-jet piston cooling. The valvetrain operates at speeds that other production engines simply don't reach.

For S2000 owners, Cerma is sound long-term protection. The F20C/F22C1 is no longer in production, parts costs are climbing, and used S2000s are appreciating in value. A one-time $105.60 application protects an engine that's increasingly difficult to replace - and the high-RPM operation is exactly where Cerma's friction reduction at the cam lobes, rocker arms, and bearings provides the most measurable benefit.

B-series (B16, B18) and earlier engines

The B16A (1989+ Civic SiR JDM, later Civic Si and Del Sol VTEC), B18C5 (1997-2001 Integra Type R), and other B-series engines are the original VTEC legends. Many are still in service today with 200,000-300,000+ miles, often in modified configurations. For B-series owners, the Cerma application is identical: 2oz gas treatment ($105.60).

The same applies to D-series engines (1.5L/1.6L SOHC Civic engines from 1984-2005) and F-series 4-cylinders (1990-2002 Accord, Prelude). These engines are increasingly rare on the road, but the ones that remain have demonstrated longevity that few modern engines can match. Cerma provides permanent protection for whatever life remains in these legendary Hondas.

9. Honda Oil Specifications and Honda Genuine Motor Oil

Honda has its own oil program (Honda Genuine Motor Oil, sometimes called HGMO) sold through Honda and Acura dealerships, but they also approve a wide range of aftermarket oils. Understanding which oil weight your Honda requires - and confirming Cerma's compatibility - is straightforward.

Common Honda oil weights:

• 0W-20 - the workhorse weight for most current production Hondas including Civic, CR-V, HR-V, Accord, Pilot (most J35 applications), Odyssey. The dominant oil weight in the modern Honda lineup.
• 5W-30 - some older Honda applications including older J35 V6, older K-series, and high-load applications. Verify your owner's manual.
• 5W-40 - the K20C1 in the Civic Type R and Acura Integra Type S specifically uses 5W-40 (per Honda's Type R-specific recommendations). Some K20C4 applications also call for 5W-30 or 5W-40 in high-load use.
• 10W-30 - older Honda engines (D-series, B-series, older F-series, older J-series) often used 5W-30 or 10W-30 from new.

Recommended Honda-compatible oils that work with Cerma:

• Honda Genuine Motor Oil (HGMO) - Honda's branded oil, available at Honda and Acura dealers
• Mobil 1 Extended Performance 0W-20 - widely available, popular Honda choice
• Mobil 1 ESP 5W-40 - for Civic Type R K20C1 applications
• Castrol Edge 0W-20 - widely available
• Pennzoil Platinum 0W-20 - widely available
• Liqui Moly Special Tec AA 0W-20 - for owners who want a premium European oil
• Valvoline Advanced Full Synthetic 0W-20 - widely available
• Amsoil Signature Series 0W-20 - for owners who want extended drain intervals

Cerma's compatibility statement

Cerma STM-3 is fully compatible with all of these oils and all Honda specifications. Cerma does not alter oil viscosity, base oil chemistry, additive package composition, or any specification compliance. The Nano Silicon Carbide ceramic particles bond to engine metal surfaces - they do not interact with the oil's chemical properties.

If your Honda or Acura dealer or independent specialist asks about your oil during service, the answer is: standard Honda-spec oil (or whatever you actually used). Cerma does not need to be disclosed - it's not part of the oil chemistry, it's bonded to your engine metal.

10. How to Install Cerma in Your Honda

Installation is straightforward whether you DIY at home or have your Honda serviced at the dealer or an independent specialist. Cerma can be added during any oil change.

1. Complete a normal oil change. Drain old oil, replace filter (Honda OEM, Mahle, K&N, or any quality filter meeting Honda specs), and add fresh oil to your specified weight - typically 0W-20 for current production Hondas, 5W-30 for older NA applications and some J35 V6 variants, and 5W-40 for the Civic Type R K20C1 (verify your owner's manual). For DIY: most Honda 4-cylinder engines hold 4-5 quarts, V6 engines hold 4.5-5.5 quarts.
2. Pour the Cerma 2oz bottle into your oil fill port. One full bottle for any Honda gas engine - inline-four or V6.
3. Replace the oil cap and start the engine. No warm-up procedure required. Drive normally including spirited driving, K-series VTEC engagement, or canyon runs. The ceramic begins bonding from the first drive.
4. Drive 3,000 to 5,000 miles on the treated oil. The ceramic particles bond to engine metal during this break-in window. Civic Type R owners typically notice smoother turbo response within the first 1,000 miles. K-series owners often report smoother VTEC engagement. J35 owners typically notice quieter cold-start operation. e:HEV hybrid owners may notice smoother gas-electric transitions.
5. Continue normal oil changes at Honda's recommended intervals via the Honda Maintenance Minder system (typically 5,000-7,500 miles for most applications, shorter for the L15B in cold-weather short-trip driving). The bonded ceramic stays - it doesn't drain out with the oil.

For complete step-by-step installation details with photos and FAQs, see our full installation guide.

11. What to Expect: First 3,000 to 5,000 Miles

First 500 miles:

Engine sound and idle quality often smooth out within the first few hundred miles. Civic Type R owners typically notice particularly smooth turbo response since the K20C1's MHI TD04 turbo benefits immediately from reduced friction. K-series owners (K20A2, K24A2, swapped K-series builds) often report particularly smooth VTEC engagement at high RPM. J35 V6 owners often report subtle smoothing of the V6's already-refined idle. e:HEV hybrid owners often notice smoother gas-electric transitions.

500 to 2,000 miles:

Throttle response feels more linear, particularly during transitions in and out of boost on turbocharged Hondas. Cold-start operation feels smoother on all Honda engines. K-series owners often notice slightly more refined high-RPM operation - the period above the VTEC engagement threshold where the engine is most mechanically active. Civic Type R owners often report more consistent torque delivery during sustained boost. J35 owners often notice smoother power delivery during highway acceleration.

2,000 to 5,000 miles:

The ceramic bond is largely complete. Friction reduction is at full effect. Many Honda owners report measurable fuel economy improvements during this window - Cerma's customer-reported range is 4-21%* depending on use patterns. For a daily-driver Civic averaging 36 mpg, even a 5% improvement adds up to meaningful annual fuel savings. For a J35-powered Pilot or Odyssey averaging 22 mpg, the percentage improvement compounds with V6 fuel costs.

5,000+ miles (permanent):

The ceramic matrix is fully bonded. From here on, your Honda has the friction reduction benefit for the life of the engine. Through every future oil change. Every cold start. Every spirited drive. Every track day. Every long road trip with the family. No reapplication, no maintenance, no recurring cost. This is the maintenance approach that supports the 250,000-400,000+ mile ownership horizons typical of dedicated Honda owners.

12. Complete Honda Drivetrain Protection

The engine treatment handles the engine. For full Honda protection, three additional Cerma products extend the same ceramic technology to your transmission, differentials, and motor oil.

13. Honda Warranty and Maintenance Plan Considerations

American Honda Motor Co. offers a 3-year/36,000-mile new vehicle limited warranty plus a 5-year/60,000-mile powertrain warranty (Acura offers 4-year/50,000-mile plus 6-year/70,000-mile powertrain). Optional extended coverage is available through Honda Care and Acura Care service contract programs. Many owners worry that aftermarket products will void these warranties.

The federal Magnuson-Moss Warranty Act protects you. American Honda Motor Co. cannot void your warranty simply because you used an aftermarket engine treatment. They cannot deny a specific warranty claim unless they can prove the aftermarket product directly caused the failure they're refusing to cover.

Why Cerma is in a particularly strong warranty position:

• EPA ETV certified - independent third-party verification of performance under controlled conditions. Almost no other engine treatment carries this credential.
• Inert ceramic chemistry - Cerma doesn't change oil viscosity, additive package, or filtration. Your Honda continues running on Honda-spec lubrication.
• Compatible with all Honda dealer service routines - every oil change at Honda's recommended Maintenance Minder intervals, every Honda Care or Acura Care visit, no changes to your routine.
• Does not interact with the Honda Maintenance Minder system - the system reads driving patterns and time-based factors, not chemical composition.

Hybrid component warranty notes (e:HEV owners):

Honda's e:HEV hybrid components carry a separate warranty (typically 8 years/100,000 miles for the high-voltage battery and electric motor components, with longer coverage in California emission-warranty states). Cerma does not interact with the hybrid components in any way - it's added to the gas engine oil only. The hybrid component warranty is unaffected by Cerma application.

For a complete breakdown of your aftermarket rights under federal law, see our complete guide to engine treatments and the Magnuson-Moss Warranty Act. Keep your purchase receipt, oil change records, and Cerma's EPA ETV documentation on file as smart practice.
