What vehicles is Cermax 5W-30 Motor Oil compatible with?

Cermax 5W-30 is suitable for all vehicle types where a 5W-30 viscosity is recommended. This includes high-performance cars, turbo-charged and supercharged gasoline engines, multi-valve fuel injected engines, passenger cars, SUVs, light vans, and trucks. It meets API service SN, SM, and ILSAC GF-5 specifications and is compatible with both domestic and foreign vehicle manufacturers' requirements.

How long does Cermax 5W-30 Motor Oil last between oil changes?

Cermax (the MAX line) is a premium 30,000-mile blend, meaning it is engineered to provide protection for up to 30,000 miles between oil changes. The standard Cerma line is a 15,000-mile blend. Always follow your vehicle manufacturer's recommended oil change intervals and monitor oil condition regularly.

Can I use Cermax 5W-30 as a break-in oil for a new engine?

Yes. Cermax 5W-30 is both an excellent break-in oil and a top-performing daily driver oil. The STM-3 technology helps establish optimal metal surface conditions from the start, creating a nano SiC matrix that laps metal surfaces to near-perfect smoothness. This helps new engines reach peak performance faster.

Do I need to use a Cerma Engine Treatment before switching to Cermax Motor Oil?

For best results, Cerma recommends following the Cerma Protocol: add the Cerma STM-3 Engine Treatment to your existing oil first, drive at least 1,500 miles, then switch to Cermax Motor Oil at your next oil change. For engines under 30,000 miles, use 1 oz of treatment. For engines over 30,000 miles, use the full 2 oz. Do not use any other additives while using Cerma-branded oils.

Q: What makes Cermax 5W-30 different from regular synthetic motor oil?

Cermax 5W-30 is the world's first self-cleaning motor oil, featuring Cerma's proprietary STM-3 technology with Nano Silicon Carbide (SiC). Unlike standard synthetic oils that only lubricate, Cermax actively cleans your engine by attracting carbon and lacquer particles into masses large enough to be filtered out. This Run Clean Technology protects against sludge, reduces friction, and creates a nano SiC matrix seal on metal surfaces for long-lasting protection up to 30,000 miles.

🔬 What Makes Cermax Different from Every Other Motor Oil?

Conventional synthetic oils — even premium brands — 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. Cermax 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 mile after mile — which is why Cermax delivers 30,000-mile drain intervals while actually making your engine cleaner over time, not dirtier.

🔬 How STM-3 Run Clean Technology Works

At the core of Cermax 5W-30 is Cerma STM-3 — the next generation 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. This technology works in multiple ways simultaneously:

Self-Cleaning Action: Prevents contaminants from depositing on metal surfaces — 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
Non-Newtonian Properties: Gets stronger under stress — maximum protection during high-load conditions

📋 How to Use Cermax 5W-30

💡 For Best Results:

For maximum protection, first treat your engine with Cerma STM-3 Engine Treatment (a one-time permanent treatment), then use Cermax 5W-30 for all subsequent oil changes. The engine treatment creates the initial deep ceramic bond, and Cermax oil continuously reinforces it. Check our Value Packages for bundled savings on treatment + oil.

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

❓ Frequently Asked Questions

What makes Cermax 5W-30 different from regular synthetic oil?

Cermax 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, Cermax permanently bonds a ceramic matrix to your engine's metal surfaces, continuously cleans deposits, and prevents contaminant buildup. This is why it achieves up to 30,000-mile drain intervals while making your engine cleaner over time.

Can I really go 30,000 miles between oil changes?

Yes. Cermax Ceramic Synthetic Motor Oil is engineered for up to 30,000-mile drain intervals under normal operating conditions. The SiC technology helps the oil maintain its protective and cleaning properties far longer than conventional synthetics. We recommend periodic oil analysis to confirm the optimal interval for your specific driving conditions, especially for severe-duty use (frequent towing, extreme temperatures, short trips).

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 Cermax oil. The engine treatment creates the initial deep ceramic bond, and Cermax oil continuously reinforces it. However, Cermax oil provides significant benefits on its own — the SiC technology will build ceramic protection over time with each oil change.

Which vehicles use 5W-30 motor oil?

5W-30 is the most widely recommended viscosity grade worldwide. It is the standard specification for most GM/Chevrolet vehicles, Toyota/Lexus, Nissan/Infiniti, Hyundai/Kia, Subaru, and many European brands. It provides excellent all-season protection with balanced fuel efficiency and wear resistance. Always confirm your vehicle's recommended viscosity in your owner's manual.

What size should I order?

For individual oil changes, order enough quarts to fill your engine plus one extra for top-offs (typically 5–7 quarts). The 12 Quart Case covers 2–3 oil changes for most vehicles and is ideal for stocking up. The 5 Gallon Pail and 55 Gallon Drum are perfect for shops and fleets. Volume discounts: buy 2 quarts save 1.35%, buy 5 quarts save 4.1%.

Is Cermax 5W-30 safe for turbocharged and supercharged engines?

Yes. Cermax 5W-30 provides superior protection for all induction (turbo and supercharged) engines. Turbochargers operate at extreme temperatures and RPMs, making the SiC ceramic protection especially valuable. The oil's excellent thermal stability and self-cleaning properties keep turbo bearings and oil passages clean and well-protected. For additional turbo protection, consider adding Cerma Turbo Nano Treatment.

What does "self-cleaning" oil mean?

Cermax's STM-3 Run Clean Technology applies a Nano SiC matrix that prevents sludge, carbon deposits, and contaminants from adhering to metal surfaces. Unlike conventional detergent-based oils that suspend particles until they're overwhelmed, Cermax creates a ceramic barrier at the molecular level that actively repels deposit formation. The result: your engine actually gets cleaner the longer you run Cermax oil.

Is Cermax available in other viscosities?

Yes. Cermax Ceramic Synthetic Motor Oil is available in multiple viscosity grades including 5W-20, 5W-30, 10W-30, 10W-40, 15W-40, and 20W-50. Visit our Motor Oil collection to find the right viscosity for your vehicle.
