A - Yes, although fuel from the refinery must meet the minimum standards for diesel this does not mean it is a high performance fuel. Our performance fuel additive provides additional cetane boosters, detergents, corrosion inhibitors, deicers, wax modifiers and anti-wax settling along with additional lubricity enhancers. The combination of these fuel enhancers extend your engines life, provide more power, better fuel mileage, and a higher reliability rating in the dead of winter. If your application is on the farm, construction site, vehicles or even in your home heating system, our performance diesel will exceed your expectations.
