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
- Change your oil — use any motor oil of your choice at your next scheduled oil change
- Add Cerma STM-3 — pour the entire 2oz bottle into your oil fill port
- Drive normally for 3,000–5,000 miles — the SiC particles will bond to metal surfaces during normal operation
- 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.

🔬 Technical & Compatibility FAQs
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.
Yes. Cerma STM-3® is safe and beneficial for turbocharged, supercharged, and hybrid gasoline engines. Turbo and supercharged engines run hotter and at higher cylinder pressures, which actually makes them better candidates for ceramic protection — the non-Newtonian dilatant properties mean Cerma delivers more protection exactly when your engine is working hardest. For hybrids, the repeated stop-start cycling benefits significantly from reduced friction at cold starts. Cerma is compatible with Atkinson-cycle, direct injection (GDI), and variable valve timing (VVT) systems.
Yes, and it may help. In engines burning oil or leaking, the underlying cause is often worn cylinder walls, degraded piston rings, or worn valve seals — all metal surfaces Cerma STM-3® can help restore. As the SiC particles bond to these worn surfaces, many customers report reduced oil consumption and, in some cases, slowed or stopped minor leaks as compression improves and heat/pressure distribution evens out. Cerma is not a leak-stop product, but it addresses the root friction-and-wear causes behind many oil-consumption issues. For severe mechanical problems, Cerma is not a substitute for proper repair.
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.
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.
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.
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.
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.

Love it. Running in my motorcycles (motorcycle version) and in my car. Have noticed improvement in gas mileage and overall smoothness on my DRZ 400 motorcycle the most. Great product.
First time user tried the oil and fuel treatments
I’ve been using Cerma products for many miles. I’m retired and have to watch my money. Cerma not only makes my vehicles run better but saves me money in the long run. I now have members of my family using cerma. GREAT PRODUCTS.
First time user and impressed with the results very pleased
Its the best for any old or new car! Thanks
Cerma helped smooth out my engine .
My Honda runs silky smooth
excellant product, now my engine trans transfer case and rear end are all covered
I love this stuff!! Followed easy instructions and my car drives amazing and the ticking sound is gone in one day!
I have a 2016 Toyota Tundra with 125 K miles. 5.7 v-8 For a while now I have heard a knocking sound coming from top end drivers side of motor.I did some research and thought it could be the cam chain tensioner. It didn’t do it all the time, but regularly. I was getting alarmed. I found your products online, and thought if something was sticking maybe your product could free things up. I said wow when I saw the price for 2 oz., but thought maybe it will work. I put it in 600 miles ago, followed the instructions and I haven’t heard anything from the engine since. I can’t believe it, this stuff is great. Thanks for making this stuff. I will be ordering your oil soon, and them other products too. Thanks again, Don
So far so good. Less noise, smoother engine, more power.
Great product, felt a difference 15-20 minutes after driving it per the instructions. Also tried the manual transmission and differential treatment. Feels like a new powertrain!! Torquey and smooth
have not received the product yet
After install and then ran almost 1500 miles and the engine noise is 15 decibels quieter. Less friction indeed. Thank you for years of great products on all my vehicles.
Just received it and still driving the 1500 mile period.
Im sure the product is as represented, will let you now.
If you are in a hurry for this product you will need to pay extra for shipping. It took a ridiculous amount of time to receive it. (3 weeks)
My feeling is that for the price of this stuff the shipping needs to be upgraded by the seller.
2009 Chevy Traverse 336,265 miles.
3 weeks and 945 miles after adding Cerma engine treatment, my motor is running better than it has in years. It just seems to get better everyday. Finally a product that delivers real results.
