Ceramic Engine Treatment for Diesel Engines

Cerma STM-3 Ceramic Engine Treatment for Diesel Engines — One-Time Nano Silicon Carbide Protection

Cerma STM-3® Diesel Engine Treatment is a one-time ceramic application that permanently bonds Nano Silicon Carbide (SiC) to the internal metal surfaces of any diesel engine — cars, pickup trucks, semi trucks, marine vessels, heavy equipment, and generators. Add it to your engine oil. Drive normally. The SiC particles do the rest.

One application delivers permanent ceramic protection that survives every oil change for the life of the engine. No reapplication. No disassembly. No downtime.

✅ What Cerma STM-3 Does for Your Diesel Engine

• Protects new engines and revives high-mileage diesels — restores compression and smoothness
• Increases horsepower and torque — less friction means more power to the wheels or PTO
• Improves fuel economy up to 21% — significant savings for diesel vehicles with high fuel costs
• Reduces emissions by up to 92% — cleaner combustion from optimized metal surfaces
• Boosts compression — SiC fills micro-imperfections in cylinder walls and piston rings
• Eliminates carbon deposits — ceramic barrier prevents buildup
• Reduces engine vibration and noise — smoother surfaces for quieter diesel operation
• Prevents hydrogen embrittlement — protects metal integrity at the molecular level
• Stops cold start problems — ceramic protection present from first crank, even at -40°F
• Lowers operating temperatures — critical for diesels running under sustained heavy load

🔬 How STM-3 Technology Works

Cerma STM-3® is not a traditional oil additive. It does not coat engine parts temporarily — it permanently changes the surface structure of the metal itself.

The Nano Silicon Carbide (SiC) particles penetrate into the sub-surfaces of your engine's metal components and create a permanent Silicon Carbide ceramic matrix. SiC has a Mohs hardness of 9.5 (just below diamond) and a melting point of 2,730°C — far exceeding any operating temperature in a diesel engine.

The result: permanently smoother, harder, more durable metal surfaces on cylinders, pistons, rings, bearings, and cams — without changing factory tolerances. Friction drops dramatically. Wear virtually stops. Performance improves measurably.

Cerma STM-3® contains 100% active ingredient — no fillers, no solvents, no petroleum additives. It does not modify your oil. It enhances your engine's metal. Safe for DPF, DOC, SCR, EGR, and all emissions equipment.

📋 How to Apply

1. Change your oil — use any diesel-rated motor oil at your next scheduled oil change
2. Add Cerma STM-3 — pour the correct dose (see sizing below) into your oil fill port
3. Drive normally — the SiC particles will bond to metal surfaces during normal operation
4. Enjoy permanent protection — the ceramic matrix is now part of your engine. No reapplication needed

Noticeable improvement in engine smoothness, vibration, and noise within the first 20 minutes of driving. Full ceramic bonding develops over the first 3,000–5,000 miles. Compatible with conventional, synthetic, and synthetic blend diesel oils. Safe for all plastics, rubber, and seals.

❓ Frequently Asked Questions

Which size do I need for my diesel engine?

Choose based on your engine displacement: 2oz for 1.0–2.8L (small diesel cars), 4oz for 3.0–4.8L (mid-size trucks), 6oz for 5.0–7.3L (full-size diesel pickups like Cummins, Power Stroke, Duramax), and 12oz for 8.0L+ (semi trucks and heavy equipment). Check your owner's manual or call 239-344-9861 if unsure.

Is this really a one-time treatment for diesel engines?

Yes. The SiC particles permanently bond to your engine's internal metal surfaces, creating a ceramic matrix within the sub-surface of the metal. This bond survives oil changes — when you drain and replace the oil, the ceramic protection stays on the metal permanently. No reapplication needed.

Is Cerma safe for diesel emissions equipment (DPF, DEF, EGR)?

Yes. Cerma STM-3® is safe for all diesel emissions equipment including DPF (Diesel Particulate Filter), DOC (Diesel Oxidation Catalyst), SCR (Selective Catalytic Reduction), EGR (Exhaust Gas Recirculation), and DEF systems. The SiC particles bond to internal engine metal only and do not interact with exhaust aftertreatment systems.

Will it work on my Cummins / Power Stroke / Duramax?

Yes. Cerma STM-3® works with all diesel engine makes and models. For the Ram Cummins 6.7L, Ford Power Stroke 6.7L, and Chevy/GMC Duramax 6.6L, use the 6oz bottle ($290.40). For older Ford 7.3L Power Stroke or International diesels, also use the 6oz size.

How much fuel can I really save?

Results vary by engine condition and driving habits. Cerma's testing shows fuel economy improvements up to 21% in diesel engines. Even a conservative 5–10% improvement on a diesel truck averaging 15 MPG and driving 20,000 miles/year at $4.00/gal saves $267–$533 annually — paying for the treatment in the first year.

What about semi trucks and fleet applications?

The 12oz bottle ($538.45) treats semi trucks and Class 8 vehicles with 8.0L+ diesel engines. For fleets, the ROI is significant — fuel savings, reduced maintenance, extended engine life, and lower emissions across every vehicle. Contact us at 239-344-9861 for fleet pricing and volume discounts.

Will it void my diesel engine warranty?

Cerma STM-3® does not modify your engine oil — it treats the metal surfaces. Under the Magnuson-Moss Warranty Act, aftermarket products cannot void a manufacturer's warranty unless the product itself causes the damage. We recommend consulting your dealer if you have specific warranty concerns.

How does cold weather performance work down to -40°F?

The SiC ceramic coating on your engine's metal surfaces is permanent and always present — even when the engine is cold. This means on startup in extreme cold, the ceramic barrier is already protecting metal-on-metal contact surfaces before oil circulates. This eliminates the cold start damage that causes the majority of diesel engine wear.
