Engine Warranty Compliance

Fuelmaster® Engine Warranty Compliance Diesel “Additive”

Diesel engine manufacturers, including Detroit Diesel, Cummins, Caterpillar and EMD, typically do not recommend “additive use” – and for good reason.

Aftermarket “additives” generally alter recommended ASTM fuel specifications. Common aftermarket “additives” often contain the following: Nitrate based cetane improvers, barium-laced smoke suppressants, biocides to kill algae – these biocides are a poison and usually make fuel dryer (less lubricity). Metallics used to act as a catalyst can produce ferrous salts, which can be abrasive.

Austech Industrial Solutions do not class Fuelmaster® as an additive.

Fuelmaster® is a complete fuel treatment that does not alter the ASTM fuel specifications (see laboratory report below).

Fuelmaster® is:  non-flammable, non-toxic, contains no metal, contains no phosphate, and is pH-neutral.

Fuelmaster® used at the recommended ratio will not damage diesel or petrol engines, and will not void engine warranty.
