Winter & Performance Diesel Additives


KEEP ENGINES CLEAN
Afton's patented GreenClean™ detergent technology provides DW-10 detergency to diesel fuel to keep the fuel system and fuel injectors clean, thereby improving fuel economy, restoring power, extending injector life, improving fuel filters, and reducing maintenance costs so that your engine is running at peak performance.

KEEP FUEL FLOWING
Diesel treatments formulated with Afton's cold flow improvers and wax anti-settling additives prevent diesel fuel line freeze-ups and diesel from gelling, thereby improving the operability of the engine in cold weather and reducing downtime and maintenance. We also offer Re-Flow® G for diesel, an Anti-Gel that melts ice and wax blockages in gelled diesel fuel.


REDUCE FRICTION
Afton Chemical offers performance fuel additives for diesel that are formulated with lubricity improvers to reduce friction in the fuel system. The additional lubrication prevents wear to extend the life of the fuel pump and reduce downtime and repair costs.


IMPROVE COMBUSTION
Cetane improvers in Afton Chemical's diesel fuel additives improve the cetane rating of diesel, resulting in reduced fuel emissions, better fuel economy, engine longevity and improved engine performance, and reduced maintenance and downtime.
Explore our catalog of finished diesel additives below. We've highlighted the key performance benefits of each grade, as well as a comparison at the bottom of the page. Afton's finished OTR® & HiTEC® diesel additives are available in drums or totes to be used as received or repacked into smaller container sizes. Want to formulate your own performance fuel additive? We also offer component fuel additive solutions for gasoline and diesel fuel.
