Best Motorcycle Engine Treatment 2026: Ceramic Protection for Every Rider
From sport bikes to vintage cruisers — how ceramic engine treatment delivers permanent protection that oil additives can't match.
The best motorcycle engine treatment in 2026 is Cerma STM-3 Motorcycle Engine Treatment ($71.50 for 1.25oz) — the only ceramic treatment that permanently bonds Nano Silicon Carbide to your engine's metal surfaces. Unlike oil additives from Lucas, Liqui Moly, or Sea Foam that drain out with every oil change, Cerma's SiC ceramic matrix (Mohs 9.5 hardness) is a one-time application that survives every oil change and delivers up to 90%* friction reduction. It works on all motorcycle types — sport bikes, cruisers, touring bikes, dirt bikes, adventure bikes, and vintage motorcycles.

Common Motorcycle Engine Treatments Compared
Motorcycle engines operate under extreme conditions — higher RPMs, tighter tolerances, and shared oil systems between engine, clutch, and sometimes transmission. That makes engine protection especially important for riders. Here's how the most popular motorcycle engine treatments stack up:
| Treatment | Technology | Duration | Motorcycle Safe? | Price / Application |
|---|---|---|---|---|
| Lucas Oil Stabilizer | Petroleum-based heavy oil | Drains at oil change | Check compatibility with wet clutch | ~$12–15 |
| Liqui Moly Motorbike Oil Additive (MoS2) | Molybdenum Disulfide | Drains at oil change | Yes — motorcycle-specific formula | ~$15–18 |
| Sea Foam Motor Treatment | Petroleum-based cleaner | Drains at oil change | Primarily a cleaner, not a protectant | ~$10–12 |
| STP Oil Treatment | ZDDP / viscosity improver | Drains at oil change | May affect wet clutch performance | ~$6–8 |
| Marvel Mystery Oil | Petroleum cleaner/lubricant | Drains at oil change | General purpose — not motorcycle-specific | ~$8–10 |
| Cerma STM-3 Motorcycle Treatment | Nano Silicon Carbide (SiC) ceramic | Permanent — survives oil changes | Yes — designed for motorcycles | $71.50 (one-time) |
Each of these products serves a purpose. Lucas and Liqui Moly can provide short-term friction reduction. Sea Foam is an effective cleaner for carbon deposits. STP thickens oil for older engines. Marvel Mystery Oil is a general-purpose maintenance fluid. But they all share one fundamental limitation.
What All Traditional Additives Have in Common
Every traditional motorcycle oil additive — regardless of brand — works by modifying the oil itself. They thicken it, add friction modifiers to it, or clean through it. This means:
Traditional oil additives protect your engine through the oil. When the oil drains, the protection drains with it. You're paying for temporary protection that resets to zero every 3,000–5,000 miles. For motorcycle riders changing oil frequently, that adds up fast.
Traditional Oil Additives
- Must be reapplied every oil change
- Protection disappears when oil drains
- Some may affect wet clutch performance
- Ongoing cost: $40–100+/year for riders
- No permanent surface modification
Cerma STM-3 Ceramic Treatment
- One-time application — never reapply
- Bonds to metal — survives every oil change
- Designed for motorcycles including wet clutch systems
- One-time cost: $71.50 — then $0 forever
- Permanent SiC ceramic matrix on all metal surfaces
The Ceramic Difference: Cerma STM-3 for Motorcycles
Cerma STM-3 Motorcycle Engine Treatment works on a completely different principle than oil additives. Instead of modifying your oil, it modifies your engine's metal surfaces directly.
The active ingredient is Nano Silicon Carbide (SiC) — a ceramic compound with a Mohs hardness of 9.5 (second only to diamond). When you add Cerma to your engine oil, the SiC nanoparticles bond to every metal surface in your engine, forming a permanent ceramic matrix. This matrix:
- → Fills micro-scratches and imperfections in the metal surface (self-healing)
- → Creates an ultra-smooth ceramic surface that reduces friction up to 90%*
- → Withstands extreme temperatures — SiC melting point is 2,730°C
- → Survives every oil change — it's bonded to the metal, not dissolved in the oil
- → Improves over the first 500+ miles as the ceramic matrix fully forms
For motorcycle engines running at 8,000–14,000+ RPM, this level of surface protection is especially valuable. The higher the RPM, the more metal-on-metal contact events per minute — and the more difference a permanent ceramic barrier makes.
The formula is 100% active ingredient, 100% organic, and made in the USA in Fort Myers, Florida. It's been on the market for over 12 years.

Works on Every Motorcycle Type
Cerma STM-3 Motorcycle Engine Treatment is formulated for all motorcycle engines. The 1.25oz size is calibrated for motorcycle engine oil capacities, and the SiC ceramic works the same way regardless of your riding style or engine configuration:
Whether you're pushing a sport bike on the track, touring cross-country on a Gold Wing, or maintaining a vintage Triumph, the treatment works the same way — it bonds to metal surfaces and creates a permanent ceramic barrier.
For riders with older or high-mileage engines, Cerma's self-healing property is especially relevant. The SiC nanoparticles fill micro-scratches and wear marks in the metal, which can restore compression and reduce blow-by in worn engines.
How to Apply — The Cerma Protocol for Motorcycles
Applying Cerma STM-3 to your motorcycle is straightforward. Follow the Cerma Protocol for best results:
- Add the engine treatment to your existing engine oil. Simply pour the 1.25oz Cerma STM-3 treatment into the oil fill port. No need to change your oil first.
- Ride your motorcycle for a minimum of 500 miles. The SiC nanoparticles need time and heat to bond to the metal surfaces. Ride normally — no special break-in procedure needed.
- Change the oil using CERMAX Synthetic Motorcycle Oil (or your preferred motorcycle oil). This removes any excess treatment and unbound particles.
- Enjoy permanent protection. The ceramic matrix is now bonded to your engine. Continue with normal oil changes using any motorcycle-safe oil brand. The treatment survives every oil change.
Do not use any other oil additives while using Cerma branded oils. The treatment needs a minimum of 500 miles of riding before your first oil change. Over the next 90 days, the Cerma process continues working on its own, creating a permanent ceramic barrier on all metal surfaces.
3-Year Cost Comparison
Motorcycle riders typically change oil more frequently than car drivers — every 3,000–5,000 miles or at least twice per season. If you're adding a traditional additive at every oil change, those costs accumulate. Here's an estimated comparison assuming 3 oil changes per year:
| Approach | Year 1 | Year 2 | Year 3 | 3-Year Total |
|---|---|---|---|---|
|
Lucas Oil Stabilizer ~$12 × 3 changes/year |
$36 | $36 | $36 | $108 |
|
Liqui Moly MoS2 ~$16 × 3 changes/year |
$48 | $48 | $48 | $144 |
|
Cerma STM-3 $71.50 one-time |
$71.50 | $0 | $0 | $71.50 |
|
Cerma Value Package $101.20 (treatment + 2qt oil) |
$101.20 | $0 | $0 | $101.20 |
Even against the cheapest additive option, Cerma pays for itself within 2 years and saves money every year after that — all while providing superior, permanent protection rather than temporary lubrication.
The Cerma Value Package for Motorcycles ($101.20, down from $150.00) is the best value for riders — you get the engine treatment plus 2 quarts of CERMAX Synthetic Motorcycle Oil in your choice of viscosity: 20w50, 10w40, 5w30, or 10w30.

🛡️ Complete Your Protection
Motorcycle engines share oil with the transmission on many bikes. For riders with separate transmission systems, consider adding Cerma transmission treatment for complete drivetrain coverage.
Which Approach Is Right for Your Bike?
Choose Lucas Oil Stabilizer if you want the cheapest possible additive and change oil very frequently — understanding protection resets at every change.
Choose Liqui Moly Motorbike MoS2 if you prefer a European-formulated motorcycle-specific additive and don't mind reapplying every oil change.
Choose Sea Foam if your primary goal is cleaning carbon deposits and sludge rather than long-term friction reduction.
Choose Cerma STM-3 Motorcycle Treatment if you want permanent ceramic protection that survives every oil change, up to 90%* friction reduction, self-healing surface repair, and a one-time cost of $71.50 — no reapplication, ever. For best value, get the Value Package ($101.20) which includes 2 quarts of CERMAX Synthetic Motorcycle Oil.
Best of both worlds: Since Cerma bonds to metal (not oil), you can still use any additive-infused oil you prefer alongside the permanent ceramic protection. They complement, not conflict.

The best motorcycle engine treatment is one that provides permanent, heat-resistant protection without affecting wet clutch performance. Cerma STM-3 Motorcycle Engine Treatment ($71.50) uses Nano Silicon Carbide ceramic that bonds permanently to metal surfaces, providing up to 90%* friction reduction that survives every oil change. It's designed specifically for motorcycle engines and works on sport bikes, cruisers, touring bikes, dirt bikes, adventure bikes, and vintage motorcycles.
Yes. Cerma STM-3 Motorcycle Engine Treatment is formulated specifically for motorcycle engines, including those with shared oil/clutch systems (wet clutches). Unlike some oil additives that contain friction modifiers which can cause clutch slipping, Cerma's SiC ceramic bonds directly to metal surfaces rather than modifying the oil's properties. This means it protects metal-to-metal contact areas without interfering with clutch plate engagement.
Traditional oil additives (Lucas, Liqui Moly, Sea Foam, etc.) drain out with every oil change and must be reapplied. Cerma STM-3 is a permanent, one-time treatment — the Nano Silicon Carbide ceramic bonds to your engine's metal surfaces and survives every oil change. You apply it once and the protection lasts for the life of the engine. The ceramic matrix begins forming within the first 500 miles and reaches full strength over the following weeks.
Yes. Cerma STM-3 is fully compatible with any motorcycle oil brand — synthetic, semi-synthetic, or conventional. The treatment bonds to the metal, not the oil, so your choice of oil doesn't affect the ceramic protection. Cerma also offers CERMAX Synthetic Motorcycle Oil in 20w50, 10w40, 5w30, and 10w30 viscosities, which is optimized to work alongside the ceramic treatment. The Motorcycle Value Package ($101.20) bundles the treatment with 2 quarts of CERMAX oil for the best value.
Cerma STM-3 is especially beneficial for high-mileage motorcycle engines. The SiC nanoparticles fill micro-scratches and wear marks in the metal surfaces (self-healing), which can help restore compression and reduce blow-by in worn engines. Riders with older bikes often report reduced engine noise, smoother operation, and improved throttle response. The treatment protects new engines from future wear and revives older engines by repairing existing surface damage.
The Cerma Motorcycle Engine Treatment ($71.50) is the 1.25oz STM-3 ceramic treatment by itself — add it to your existing motorcycle oil. The Cerma Motorcycle Value Package ($101.20, regularly $150.00) includes the 1.25oz treatment PLUS 2 quarts of CERMAX Synthetic Motorcycle Oil in your choice of viscosity (20w50, 10w40, 5w30, or 10w30). The Value Package saves $48.80 compared to buying the treatment and oil separately, and it follows the Cerma Protocol: add treatment to existing oil, ride 500 miles, then change to CERMAX oil.
