Cerma STM-3 Engine Treatment for Diesel Semi Trucks – One-Time Ceramic Engine Treatment with Nano Silicon Carbide – Restores Performance, Reduces Friction and Wear – ETV Verified – Made in USA (12 oz)

Cerma STM-3 Engine Treatment for Diesel Semi Trucks is a one-time application that permanently bonds Nano Silicon Carbide (SiC) ceramic to your diesel engine's internal metal surfaces. This 12 oz dosage is specifically formulated for Class 7 and Class 8 semi trucks and heavy-duty commercial diesel engines that operate under the most demanding conditions in the transportation industry. Unlike traditional oil additives that wash out with every oil change, Cerma's SiC ceramic layer becomes part of the metal itself, creating a surface hardness of Mohs 9.5 — nearly as hard as diamond. This permanent ceramic bond restores lost compression, cleans carbon buildup, and smooths worn surfaces without altering factory tolerances. The result is measurable improvements in horsepower, torque, fuel economy, and emission levels. Independent testing documented fuel savings up to 21% and emission reductions up to 92%, depending on engine age and condition. For owner-operators running 100,000 or more miles per year, even a 5% improvement in fuel economy represents thousands of dollars in annual savings. Cerma STM-3 eliminates destructive engine harmonics that accelerate wear in heavy-duty diesel engines. By reducing metal-to-metal friction at the molecular level, Cerma lowers operating temperatures, stops cold start problems in temperatures as low as -40 degrees F, and prevents hydrogen embrittlement damage — a leading cause of premature diesel engine failure. The treatment helps extend engine life between major overhauls. Application is simple: add the full 12 oz treatment to your diesel engine oil and drive normally. The SiC ceramic bonds during normal operation with no flush, no downtime, and no special procedures required. Cerma does not require re-treatment in most cases, making it a cost-effective investment in long-term engine protection. Compatible with all major semi truck diesel engines including Cummins, Detroit Diesel, Caterpillar, PACCAR, Volvo, and Navistar. Also suitable for buses, heavy equipment, marine diesel, and industrial applications. Safe for all engine components including plastics, rubber, and seals. Works with all conventional and synthetic diesel motor oils. Cerma STM-3 contains no PTFE and no solvents. All performance claims have been independently verified through the EPA Environmental Technology Verification (ETV) Program and are supported by over 14 years of documented real-world testing data. Manufactured in Fort Myers, FL by Cerma Treatment (Bijou Inc.).

• ONE-TIME CERAMIC ENGINE TREATMENT FOR SEMI TRUCKS: The 12 oz dosage is formulated for Class 7 and Class 8 semi trucks and heavy-duty commercial diesel engines. Add Cerma STM-3 to your engine oil and drive. The Nano Silicon Carbide (SiC) formula permanently bonds a micro-ceramic layer to all internal metal surfaces, creating a surface hardness rated Mohs 9.5 that does not wear off or wash out with oil changes
• RESTORES ENGINE PERFORMANCE AND EFFICIENCY: Permanently bonds to metal surfaces to restore lost compression, clean carbon buildup, and smooth worn surfaces without altering factory tolerances. Delivers measurable improvements in horsepower, torque, fuel economy, and emission levels through advanced ceramic bonding technology
• REDUCES FRICTION, VIBRATION, AND NOISE: The permanent SiC ceramic surface reduces metal-to-metal contact throughout the engine, lowering operating temperatures and eliminating destructive harmonics that accelerate wear in hard-working diesel engines. Prevents hydrogen embrittlement damage and stops cold start problems in temperatures as low as -40 degrees F. Extends engine life between overhauls
• SAFE FOR ALL HEAVY-DUTY DIESEL ENGINES: Compatible with all semi truck engines including Cummins, Detroit Diesel, Caterpillar, PACCAR, Volvo, and Navistar. Also works in buses, heavy equipment, marine diesel, and industrial applications. Contains no PTFE, no solvents, and no harmful chemicals. Will not harm plastics, rubber, or seals. Works with all conventional and synthetic diesel motor oils
• ETV PROGRAM VERIFIED: Cerma is the only engine treatment to complete the EPA Environmental Technology Verification (ETV) Program, with performance claims verified through independent third-party testing. All claims supported by over 14 years of documented real-world data. Manufactured by Cerma Treatment (Bijou Inc.) in Fort Myers, FL. All products fully insured for US and international use
