Cerma Ceramic Diesel Fuel Treatment — STM-3 Nano Silicon Carbide 6-in-1 Diesel Fuel System Protection
Cerma STM-3® Ceramic Diesel Fuel Treatment is the only diesel fuel treatment that uses Nano Silicon Carbide (SiC) technology to deliver 6-in-1 fuel system protection specifically formulated for diesel engines. It cleans injectors, lubricates the upper engine with ceramic particles, removes water, boosts cetane, prevents fuel gelling, and conditions your entire diesel fuel system — all in one bottle.
Diesel fuel has less natural lubricity than gasoline, making upper engine lubrication even more critical. Cerma's SiC particles release the lubrication trapped inside diesel fuel molecules, providing continuous ceramic protection that no conventional diesel fuel additive can match.
✅ 6 Functions in One Bottle
- Cleans diesel injectors and removes carbon deposits — ceramic-enhanced cleaning action restores spray patterns and fuel atomization
- Lubricates the upper engine — SiC particles coat upper cylinders, fuel pump, and injectors (areas motor oil doesn't reach)
- Removes water and moisture — pulls water from the fuel system to prevent corrosion, microbial growth, and injector damage
- Boosts combustion quality — naturally improves diesel combustion efficiency
- Prevents fuel gelling — anti-gelling properties keep diesel fuel flowing in cold weather and extreme temperatures
- Conditions entire fuel system — ongoing ceramic protection for high-pressure fuel pump, tank, lines, and injectors
💡 Why diesel engines need Cerma: Modern diesel fuel systems operate at extreme pressures (30,000+ PSI in common rail systems). At these pressures, even microscopic wear on injector tips degrades spray patterns and reduces efficiency. Cerma's SiC ceramic particles protect these precision components at a level conventional diesel additives cannot.
📋 How to Use
Dosage: 1 oz per 40 gallons of diesel fuel. Add 1 oz for each additional 40 gallons.
- First use: Add Cerma Diesel Fuel Treatment before filling your tank with diesel
- Ongoing use: Add at every fill-up, weekly, or monthly — whatever schedule fits your driving or operating habits
Cerma Diesel Fuel Treatment is a continuous-use product — unlike Cerma Engine Treatment (one-time), you add it regularly for ongoing fuel system protection. Fleet operators and long-haul drivers who use it at every fill-up report the best results.

🔬 The Science: Nano Silicon Carbide (SiC) in Diesel Fuel
Silicon Carbide is one of the hardest compounds on earth — Mohs hardness 9.5 (just below diamond) with a melting point of 2,730°C. When suspended in Cerma's diesel fuel treatment at the nanoscale, SiC particles release the lubrication trapped inside diesel fuel molecules and coat the upper engine, high-pressure fuel pump, injectors, and fuel lines with ceramic protection.
This is especially important for modern common rail diesel systems where fuel pressures exceed 30,000 PSI and fuel acts as the primary lubricant for the high-pressure pump. Cerma's SiC particles provide ceramic-level protection at these extreme pressures — something petroleum-based additives cannot do.
Cerma Diesel Fuel Treatment is also a non-Newtonian dilatant fluid — it provides more protection under higher stress. When your diesel works harder (towing, climbing, full load), the treatment works harder. Learn about non-Newtonian fluids →

- Cerma Transmission Treatment — one-time ceramic protection for transmissions ($70.40 cars, $193.60 semis)
- Cerma Gear Box / Axle Treatment — ceramic protection for differentials and transfer cases
- Cerma Synthetic Motor Oil — SiC-enhanced diesel oil with extended change intervals
🔬 Technical & Compatibility FAQs
Yes. Cerma Diesel Fuel Treatment is safe for all diesel fuel systems, including high-pressure common rail (HPCR) systems from Bosch, Denso, and Delphi operating at 30,000+ PSI. The Nano SiC particles are engineered at a sub-micron scale to pass safely through fuel filters and injector nozzles while coating precision components with ceramic protection — ideal for modern Cummins, Duramax, Power Stroke, VW TDI, and Mercedes BlueTEC engines.
Yes. Cerma Diesel Fuel Treatment is fully compatible with DPF (Diesel Particulate Filter), DOC (Diesel Oxidation Catalyst), SCR (Selective Catalytic Reduction), EGR (Exhaust Gas Recirculation), and DEF (Diesel Exhaust Fluid) systems. The SiC ceramic particles interact with fuel system metal surfaces only — they do not affect exhaust aftertreatment equipment, do not contain solvents or harmful detergents, and will not disrupt regen cycles.
Yes. Water contamination is one of the biggest threats to diesel fuel systems — causing corrosion, microbial growth (diesel bug), injector damage, and fuel pump failure. Water removal is one of the 6 built-in functions of Cerma Diesel Fuel Treatment: the formula pulls water out of solution in your fuel tank so it can be processed through the fuel/water separator safely. No separate water-removal additive is needed when using Cerma.
Cerma is a catalyst, not a chemical additive, so modest over-dosing is not harmful — but it's also not beneficial. Sticking to 1 oz per 40 gallons gives you optimal performance without waste. If you accidentally add double the recommended amount, your engine and fuel system will not be damaged. For ongoing regular use, stay at the recommended dose to get the best value from each bottle.
Scale the dosage to your tank size: Pickup (25–35 gallon tank): 1 oz per fill-up. Large pickup / medium-duty (40–60 gallons): 1.5 oz per fill-up. Semi truck (100–150 gallons): 2.5–3.5 oz per fill-up. Dual saddle tank semi (200+ gallons): 5 oz split between both tanks. The 16 oz bottle treats approximately 640 gallons of diesel — about 20 pickup fill-ups or 5 semi truck fill-ups.
Yes — older pre-emissions-era diesels actually benefit significantly from Cerma. Engines like the Cummins 5.9 12V/24V, 7.3L Power Stroke, 6.5L Detroit, and older Navistar platforms were designed for the higher-lubricity diesel fuel of that era. With today's Ultra-Low Sulfur Diesel (ULSD) having reduced lubricity, these older engines can suffer accelerated injector pump and injector wear. Cerma restores ceramic-level lubricity to modern ULSD, helping older diesels run on today's fuel the way they were originally engineered to run.
Yes. Cerma Diesel Fuel Treatment is used extensively in marine diesel applications (inboard pleasure craft, commercial fishing vessels, tug boats), standby and portable generators, agricultural equipment (tractors, combines), construction equipment (excavators, loaders, skid steers), and mining equipment. Dosage is the same — 1 oz per 40 gallons — regardless of application. For marine use, it also helps prevent the fuel contamination issues that come from condensation in partially-full tanks during storage.
Most users notice changes within the first 1–2 tanks of treated fuel. Common early improvements include smoother idle, quieter engine sound (especially at startup), cleaner throttle response, and often a noticeable uptick in fuel economy as injectors regain optimal spray patterns. Maximum ceramic protection builds over the first 3–5 fill-ups as SiC particles coat fuel system components. Older or neglected diesels typically see more dramatic improvements than newer, well-maintained engines. Fleet data shows 2–6% fuel economy gains with consistent use.
