Cerma Synthetic Ceramic 10W-30 Motor Oil — STM-3 Nano Silicon Carbide Technology | Up to 15,000-Mile Oil Changes

Experience the world's first self-cleaning motor oil at a value price point. Cerma Synthetic Ceramic 10W-30 Motor Oil is engineered with Cerma STM-3 Run Clean Technology featuring Nano Silicon Carbide (SiC) for up to 15,000-mile oil change intervals — double the drain interval of conventional synthetic oils. This ceramic motor oil permanently bonds a diamond-hard SiC matrix to metal sub-surfaces, continuously cleaning, protecting, and restoring your engine with every mile. 10W-30 is the trusted all-purpose viscosity ideal for warmer climates, higher-mileage engines, marine applications, RVs, and a wide range of vehicles and equipment. Available in quart, gallon, case, pail, and drum sizes.

⬆️ Looking for 30,000-Mile Protection?

This is Cerma 10W-30 — our 15,000-mile ceramic synthetic oil. For maximum drain intervals up to 30,000 miles, upgrade to Cermax Ceramic 10W-30 Synthetic Motor Oil. Both use STM-3 SiC technology — Cermax features a higher concentration for extended performance.

🔬 What Makes Cerma Different from Every Other Motor Oil?

Conventional synthetic oils simply lubricate. They sit between metal surfaces and reduce friction temporarily, but do nothing to permanently repair wear or prevent deposit formation at the molecular level. Cerma is fundamentally different. 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 matrix continuously cleans engine surfaces, prevents contaminants from depositing on metal, and maintains peak performance — delivering 15,000-mile drain intervals while actually making your engine cleaner over time, not dirtier.

🌡️ Why 10W-30?

10W-30 is the classic all-purpose motor oil viscosity. Its slightly thicker film at operating temperature provides extra protection for higher-mileage engines, warmer climates, RVs and recreational vehicles, marine and watercraft engines, and older vehicles originally designed around 10W-30 specifications. It's also the standard small engine grade for generators, lawn mowers, and power equipment.

🔬 How STM-3 Run Clean Technology Works

At the core of Cerma 10W-30 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 engine:

  • Self-Cleaning Action: Attracts carbon and lacquer into filterable masses — your engine gets cleaner over time, not dirtier
  • 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, lowering friction, harmonics, and vibration
  • Power Restoration: Fills micro-imperfections in cylinder walls, restoring horsepower and torque
  • Carbon Guard: Protects against performance-degrading sludge and abrasive carbon buildup
  • Moisture Guard: Superior protection against moisture contamination and corrosion — important for marine use
  • Non-Newtonian Properties: Gets stronger under stress — maximum protection during high-load conditions

📋 How to Use Cerma 10W-30

💡 For Best Results:

For maximum protection, first treat your engine with Cerma STM-3 Engine Treatment (a one-time permanent treatment), then use Cerma 10W-30 for all subsequent oil changes. The engine treatment creates the initial deep ceramic bond, and Cerma oil continuously reinforces it. Check our Value Packages for bundled savings on treatment + oil.

  1. Check Capacity: Refer to your owner's manual for your engine's exact oil capacity and confirm 10W-30 is the recommended viscosity.
  2. Drain Old Oil: Warm your engine, then drain existing oil and replace the oil filter.
  3. Fill with Cerma: Add the correct amount of Cerma Synthetic Ceramic 10W-30 Motor Oil.
  4. Drive & Enjoy: Drive or operate normally. Cerma provides up to 15,000 miles of protection per oil change.
  5. Do Not Mix Additives: Cerma is a complete protection system. Do not add any other oil additives or treatments.

❓ Frequently Asked Questions

What's the difference between Cerma 10W-30 and Cermax 10W-30?
Both use Cerma's STM-3 Nano Silicon Carbide (SiC) Run Clean Technology — the same revolutionary self-cleaning ceramic oil technology. The key difference is concentration and drain interval: Cerma 10W-30 provides up to 15,000-mile oil changes at a lower price per quart, while Cermax 10W-30 has a higher SiC concentration for up to 30,000-mile drain intervals. Both permanently bond ceramic protection to your engine. Choose Cerma for excellent value, or upgrade to Cermax for maximum extended drain performance.
What makes Cerma 10W-30 different from regular synthetic oil?
Cerma contains STM-3 Run Clean Technology with Nano Silicon Carbide (SiC) — a ceramic compound nearly as hard as diamond (Mohs 9.5). Unlike conventional synthetics that only lubricate, Cerma permanently bonds a ceramic matrix to your engine's metal surfaces, continuously cleans deposits, and prevents contaminant buildup. The SiC Run Clean technology attracts carbon and lacquer into filterable masses, creating a full self-cleaning lubrication system.
Can I really go 15,000 miles between oil changes?
Yes. Cerma Synthetic Ceramic Motor Oil is engineered for up to 15,000-mile drain intervals under normal operating conditions. The SiC technology helps the oil maintain its protective and cleaning properties longer than conventional synthetics. For severe-duty use (frequent towing, extreme temperatures, marine operation), we recommend periodic oil analysis to confirm the optimal interval.
Can I use Cerma 10W-30 in my RV or motorhome?
Yes — Cerma 10W-30 is an excellent choice for gasoline-powered RVs and motorhomes. The 15,000-mile drain interval means fewer maintenance stops during long trips, and the SiC ceramic protection is especially valuable for RV engines that may sit idle for extended periods between trips. The permanent ceramic bond protects engine surfaces even when the oil has drained down, ensuring protection from the first start of the season.
Can I use Cerma 10W-30 in my boat or watercraft?
Yes. Cerma 10W-30 works well in marine gasoline engines. The Moisture Guard technology provides protection against corrosion in humid, saltwater, and freshwater environments. The SiC ceramic bond is especially valuable for marine engines that sit idle between uses, providing permanent protection at the metal surface level even when oil drains from surfaces during storage.
Do I need the Cerma Engine Treatment too, or just the oil?
For maximum results, we recommend starting with the Cerma STM-3 Engine Treatment (a one-time, permanent treatment) before switching to Cerma oil. The engine treatment creates the initial deep ceramic bond, and Cerma oil continuously reinforces it. However, Cerma oil provides significant benefits on its own — the SiC technology will build ceramic protection over time with each oil change.
What does "self-cleaning" oil mean?
Cerma's STM-3 Run Clean Technology applies a Nano SiC matrix that prevents sludge, carbon deposits, and contaminants from adhering to metal surfaces. The SiC technology attracts carbon and lacquer into filterable masses, creating a full self-cleaning lubrication system. Unlike conventional detergent-based oils that suspend particles until they're overwhelmed, Cerma creates a ceramic barrier that actively repels deposit formation. Your engine actually gets cleaner the longer you run Cerma oil.
Is Cerma available in other viscosities?
Yes. Cerma Synthetic Ceramic Motor Oil (15,000-mile) is available in multiple viscosity grades. For 30,000-mile intervals, see our Cermax Ceramic Synthetic Motor Oil line. Visit our Motor Oil collection to find the right oil for your vehicle.
