Ceramic Engine Treatment for Gas Engines

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

Cerma STM-3® Engine Treatment is a one-time ceramic application that permanently bonds Nano Silicon Carbide (SiC) to your engine's internal metal surfaces. One bottle treats all gasoline engines from 4 to 8 cylinders — cars, trucks, SUVs, and equipment. No reapplication. No disassembly. Permanent protection.

Simply add the 2oz bottle to your engine oil at your next oil change. The SiC particles penetrate and seal within the sub-surfaces of the metal, creating a ceramic matrix that reduces friction, eliminates wear, and optimizes performance for the life of the engine.

✅ What Cerma STM-3 Does for Your Gas Engine

• Protects new engines — ceramic barrier from day one prevents break-in wear
• Revives older engines — restores compression and smoothness in high-mileage engines
• Increases horsepower and torque — less friction means more power to the wheels
• Improves fuel economy — reduced internal friction lowers fuel consumption
• Reduces emissions — cleaner combustion from optimized metal surfaces
• Eliminates carbon deposits — SiC prevents buildup on pistons, rings, and valves
• Reduces engine vibration and noise — smoother surfaces mean quieter operation
• Prevents hydrogen embrittlement — protects metal integrity at the molecular level
• Eliminates cold start problems — ceramic protection is present from the first crank
• Lowers operating temperatures — less friction generates less heat

🔬 How STM-3 Technology Works

Cerma STM-3® is not a traditional oil additive. It does not coat engine parts — 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 Silicon Carbide ceramic matrix. This matrix is known for its extraordinary strength, durability, smoothness, and heat resistance. SiC has a Mohs hardness of 9.5 (just below diamond) and a melting point of 2,730°C — far beyond any temperature your engine will ever reach.

The result: a permanently smoother, harder, more durable surface on every internal metal component — without changing factory tolerances. Friction drops dramatically. Wear virtually stops. Performance improves measurably.

Cerma STM-3® contains 100% active ingredient — no fillers, no carrier solvents, no petroleum additives. It does not modify your oil. It enhances your engine's metal.

📋 How to Apply

1. Change your oil — use any motor oil of your choice at your next scheduled oil change
2. Add Cerma STM-3 — pour the entire 2oz bottle into your oil fill port
3. Drive normally for 3,000–5,000 miles — 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, ever

Safe for all gasoline engines. Compatible with conventional, synthetic, and synthetic blend motor oils. Safe for catalytic converters, O2 sensors, plastics, rubber, and all seals.

❓ Frequently Asked Questions

How much Cerma STM-3 do I need for my gas engine?

One 2oz bottle treats ALL gasoline engines — 4-cylinder, 5-cylinder, 6-cylinder, and 8-cylinder. There is one size for all gas engines at $105.60. No need to calculate engine displacement or cylinder count.

Is Cerma STM-3 really a one-time treatment?

Yes. The Nano Silicon Carbide 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 — even when you drain and replace the oil, the SiC ceramic protection remains permanently on the metal. No reapplication is ever needed.

Will Cerma STM-3 void my vehicle warranty?

Cerma STM-3® does not modify your engine oil — it treats the metal surfaces themselves. 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 or mechanic if you have specific warranty concerns.

What type of oil should I use with Cerma STM-3?

Cerma STM-3® works with any motor oil — conventional, synthetic, or synthetic blend. Use whatever oil your vehicle manufacturer recommends. The treatment bonds to metal, not oil, so your oil choice doesn't affect the ceramic protection. For maximum benefit, consider Cerma Synthetic Motor Oil which has SiC technology built into the oil itself.

How is Cerma different from AMSOIL, Lucas, or Sea Foam?

AMSOIL, Lucas, and Sea Foam are traditional petroleum-based additives that coat engine parts temporarily and wash out with every oil change. Cerma STM-3® uses Nano Silicon Carbide to permanently bond a ceramic matrix to your engine's metal surfaces. One application lasts forever. No other engine treatment uses SiC ceramic technology. See our full comparison vs AMSOIL and comparison vs Lucas.

What is a non-Newtonian dilatant fluid?

Cerma products are the only non-Newtonian dilatant fluids in the automotive industry. This means they get thicker and more protective under higher stress — the opposite of conventional oils which maintain constant viscosity. When your engine works harder (towing, merging, climbing), Cerma provides more protection automatically. Read our complete guide to Newtonian vs Non-Newtonian fluids.

Can I use Cerma STM-3 in a high-mileage engine?

Yes — high-mileage engines often show the most dramatic improvement. Cerma STM-3® fills micro-imperfections in worn metal surfaces with SiC ceramic, restoring compression, reducing oil consumption, and quieting engine noise. Many customers report noticeable improvement in engines with 100,000+ miles.

Is Cerma safe for my catalytic converter and O2 sensors?

Yes. Cerma STM-3® is completely safe for catalytic converters, oxygen sensors, plastics, rubber, seals, and gaskets. The SiC particles bond exclusively to internal metal engine surfaces and do not affect exhaust system components or emissions equipment.
