Cerma Ceramic Fuel Treatment for Diesel Engines

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

📋 How to Use

Dosage: 1 oz per 40 gallons of diesel fuel. Add 1 oz for each additional 40 gallons.

1. First use: Add Cerma Diesel Fuel Treatment before filling your tank with diesel
2. 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.

🚛 Who Uses Cerma Diesel Fuel Treatment

• Diesel pickup truck owners — Ram Cummins, Ford Power Stroke, Chevy Duramax
• Long-haul truck operators — owner-operators running high-mileage routes
• Fleet managers — delivery vehicles, service trucks, transit
• Diesel car owners — VW TDI, BMW diesel, Mercedes diesel
• Marine diesel operators — inboard diesel boats, commercial vessels
• Heavy equipment operators — construction, agriculture, mining
• Generator operators — standby and portable diesel generators

🔬 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 →

🔗 Complete Diesel Protection

Cerma Diesel Fuel Treatment protects from the fuel side. For total diesel engine coverage, pair with:

• Cerma STM-3 Diesel Engine Treatment — one-time ceramic protection from the oil side (from $105.60)
• 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

❓ Frequently Asked Questions

How often do I use Cerma Diesel Fuel Treatment?

Cerma Diesel Fuel Treatment is a continuous-use product. Add 1oz per 40 gallons of diesel fuel at every fill-up, weekly, or monthly — whatever schedule works for your operation. Fleet operators and long-haul drivers report the best results with consistent use at every fill-up.

What is the dosage for diesel?

1 oz per 40 gallons of diesel fuel. For large tanks (semi trucks with 100+ gallon tanks), add 2.5–3oz per fill-up. For a typical diesel pickup with a 30-gallon tank, 1oz per fill-up is sufficient.

Will it prevent diesel fuel gelling in winter?

Yes. Cerma Diesel Fuel Treatment has anti-gelling properties that keep diesel fuel flowing in cold weather. This is one of the 6 functions built into the SiC ceramic formula — no separate anti-gel additive needed. For extreme cold conditions, regular use provides the best protection.

Is this safe for my high-pressure common rail diesel?

Yes. Cerma Diesel Fuel Treatment is safe for all diesel fuel systems including high-pressure common rail (HPCR) systems from Bosch, Denso, and Delphi. The Nano SiC particles are sized to pass safely through fuel filters and injector nozzles while providing ceramic protection to precision components operating at 30,000+ PSI.

Can I use this with Cerma Diesel Engine Treatment?

Yes — and it's the recommended combination. Cerma Diesel Engine Treatment permanently bonds ceramic to internal engine surfaces from the oil side (one-time application). Cerma Diesel Fuel Treatment continuously protects the fuel system and upper engine from the fuel side. Together, they provide complete ceramic protection for every metal surface in your diesel engine.

How is this different from the gasoline version?

Both use the same STM-3 Nano Silicon Carbide technology and provide 6-in-1 protection. The diesel formulation is specifically optimized for diesel fuel chemistry, higher injection pressures, and the different lubricity requirements of diesel engines. For gasoline engines, use Cerma Gasoline Fuel Treatment.

Does it remove water from diesel fuel?

Yes. Water contamination is one of the biggest threats to diesel fuel systems — causing corrosion, microbial growth (diesel bug), and injector damage. Cerma Diesel Fuel Treatment removes water and moisture from the fuel system as one of its 6 built-in functions.

Is it safe for DPF, DEF, and diesel emissions systems?

Yes. Cerma Diesel Fuel Treatment is completely safe for DPF (Diesel Particulate Filter), DOC (Diesel Oxidation Catalyst), SCR (Selective Catalytic Reduction), EGR, and DEF systems. The SiC particles interact with fuel system metal components only and do not affect exhaust aftertreatment equipment.
