Is Cermax Ceramic Motorcycle Oil safe for wet clutch motorcycles?

Yes. Cermax 4-Cycle Ceramic Synthetic Motorcycle Oil is specifically formulated to be compatible with wet clutch systems found in most motorcycles. Unlike automotive oils that contain friction modifiers which can cause clutch slipping, Cermax Motorcycle Oil provides full engine protection with STM-3 SiC technology while maintaining proper clutch engagement and feel.

What viscosity grades are available for Cermax Motorcycle Oil?

Cermax 4-Cycle Ceramic Synthetic Motorcycle Oil is available in multiple viscosity grades including 10W-30, 10W-40, 5W-30, and 20W-50 to match your motorcycle manufacturer's specifications. Always use the viscosity recommended in your owner's manual for optimal protection and performance.

Can I use Cermax 4-Cycle Oil in my ATV, UTV, or other powersport vehicles?

Yes. Cermax 4-Cycle Ceramic Synthetic Oil is suitable for all 4-cycle engines including motorcycles, ATVs, UTVs, side-by-sides, and other powersport vehicles. Select the viscosity grade recommended by your vehicle manufacturer. The STM-3 SiC technology provides the same friction reduction and engine protection benefits across all 4-cycle applications.

How long does Cermax Motorcycle Oil last between changes?

Cermax Ceramic Motorcycle Oil is engineered for extended protection thanks to its advanced carbon and moisture guard formula. However, motorcycle oil change intervals vary significantly based on engine type, riding conditions, and manufacturer recommendations. Always follow your motorcycle manufacturer's specified oil change intervals, especially for high-performance and air-cooled engines that place greater demands on the oil.

Q: What makes Cermax Motorcycle Oil different from regular motorcycle oils?

Cermax Motorcycle Oil contains Cerma's proprietary STM-3 technology with Nano Silicon Carbide (SiC) particles. While conventional motorcycle oils only lubricate, Cermax actively treats metal surfaces at the molecular level, creating an ultra-smooth ceramic surface that reduces friction, lowers operating temperatures, and provides a self-cleaning engine system. This results in smoother shifting, more responsive throttle, and extended engine life.

🔬 Why Motorcycle Engines Need Ceramic Protection

Motorcycle engines operate under more extreme conditions than car engines — higher RPMs, higher temperatures, and smaller oil capacities that put more stress on every drop of oil. Air-cooled engines run even hotter. Cermax 4-Cycle Oil is built for this. Its STM-3 technology applies a permanent Nano Silicon Carbide (SiC) matrix seal within the metal sub-surfaces of your engine. SiC has a Mohs hardness of 9.5 (nearly as hard as diamond) and a melting point of 2,730°C. This ceramic bond provides protection independent of oil temperature — so even when your engine is running at peak heat, the SiC barrier is protecting cylinder walls, bearings, and valve train components at the molecular level.

🔬 How STM-3 Run Clean Technology Works in Your Motorcycle

At the core of Cermax 4-Cycle Oil is Cerma STM-3 — an advanced lubricating oil with SiC (Run Clean) technology. The 100% active ingredient applies a permanent Nano Silicon Carbide (SiC) matrix seal within the metal sub-surfaces of your motorcycle engine:

Self-Cleaning Action: Attracts carbon and lacquer into filterable masses — your engine stays cleaner between oil changes
Permanent Ceramic Bond: SiC particles bond to metal at the molecular level, creating a diamond-hard surface (Mohs 9.5)
Friction Reduction: Reduces metal-to-metal contact at high RPMs where motorcycle engines operate
Power Restoration: Fills micro-imperfections in cylinder walls, restoring compression and power
High-Temperature Stability: SiC melting point of 2,730°C — protection far beyond any oil's thermal limits
Non-Newtonian Properties: Gets stronger under stress — maximum protection during aggressive riding

📋 How to Use Cermax 4-Cycle Motorcycle Oil

Select Your Viscosity: Choose 10W-40, 5W-30, 10W-30, or 20W-50 based on your motorcycle manufacturer's recommendation.
Drain Old Oil: Warm the engine, then drain the existing oil completely. Replace the oil filter.
Fill with Cermax: Add the correct amount of Cermax 4-Cycle Motorcycle Oil per your owner's manual.
Run the Engine: Start the engine and let it idle for a minimum of 10 minutes to circulate the oil through all passages.
Check Level: After running, check the oil level and top off if necessary.
Ride & Enjoy: The SiC ceramic technology begins bonding immediately and strengthens over the first miles of riding.

❓ Frequently Asked Questions

What makes Cermax Motorcycle Oil different from regular motorcycle synthetic oil?

Cermax contains STM-3 Nano Silicon Carbide (SiC) Run Clean Technology — a ceramic compound nearly as hard as diamond (Mohs 9.5). Unlike conventional motorcycle synthetics that only lubricate, Cermax permanently bonds a ceramic matrix to your engine's metal surfaces. This provides protection independent of oil temperature — critical for motorcycle engines that run at higher RPMs and temperatures than car engines. The SiC technology also self-cleans by attracting carbon and lacquer into filterable masses, keeping your engine cleaner between oil changes.

Which viscosity should I choose for my motorcycle?

Always use the viscosity recommended in your motorcycle's owner's manual. General guidelines: 10W-40 is the most common motorcycle viscosity and works for most sport bikes, standards, and many cruisers. 20W-50 is standard for Harley-Davidson V-twins and large air-cooled engines. 5W-30 is best for cold-climate riding and bikes requiring lighter oil. 10W-30 is an all-purpose option for bikes that spec it. When in doubt, check your owner's manual or contact us at 239-344-9861.

Is Cermax safe for my Harley-Davidson?

Yes. Cermax 4-Cycle Oil in 20W-50 is an excellent choice for Harley-Davidson V-twin engines, which are air-cooled and run at higher temperatures than liquid-cooled engines. The SiC ceramic bond is especially valuable for air-cooled engines because it provides protection at the metal surface level independent of oil temperature — so even when your HD engine is running hot in traffic or on a long summer ride, the ceramic barrier maintains full protection.

Can I use Cermax 4-Cycle Oil in a wet-clutch motorcycle?

Yes. Cermax 4-Cycle Motorcycle Oil is formulated to be compatible with wet clutch systems found in most Japanese and European motorcycles. The PTFE-free, no-foul formula is designed to provide engine protection without causing clutch slippage. Always use the viscosity grade recommended by your motorcycle manufacturer for wet-clutch applications.

How often should I change Cermax Motorcycle Oil?

Follow your motorcycle manufacturer's recommended oil change interval. Because Cermax's SiC technology keeps the oil and engine cleaner, the oil maintains its protective properties longer. However, motorcycle engines have smaller oil capacities and operate at higher stress levels than car engines, so we recommend following manufacturer intervals for optimal protection.

Do I also need the Cerma Engine Treatment for my motorcycle?

For maximum results, we recommend starting with the Cerma STM-3 Engine Treatment (a one-time, permanent treatment) before switching to Cermax oil. The engine treatment creates a deeper initial ceramic bond, and Cermax oil then maintains and reinforces it. However, Cermax oil provides significant SiC ceramic benefits on its own and will build protection over time with each oil change.

Can I use this in a 2-stroke motorcycle engine?

No. Cermax 4-Cycle Oil is specifically formulated for 4-cycle (4-stroke) motorcycle engines. For 2-stroke engines, see our 2-Cycle Oil options. Using 4-cycle oil in a 2-stroke engine can cause damage.

What does "no-foul formula" mean?

"No-foul" means Cermax 4-Cycle Oil is formulated to keep spark plugs and combustion chambers clean. Combined with low smoke emission and the SiC self-cleaning technology, Cermax prevents the carbon deposits that cause spark plug fouling, misfires, and hard starts — keeping your motorcycle running cleanly and reliably.
