Exocet Gas Oil Supreme is a premium diesel fuel additive formulated to enhance engine performance and protection. It promotes easier starting, improved pulling power, and smoother power delivery while reducing visible exhaust smoke through more efficient combustion.
Designed to complement modern engine calibrations, it increases fuel lubricity to help offset the effects of reduced sulphur content in today’s fuels. This added lubrication protects fuel pumps and injectors from premature wear by reducing internal friction.
It also improves water resistance in fuel, helping to prevent emulsion formation and the filter blockages that can result, ensuring cleaner operation and improved overall reliability.

Forklifts, airport vehicles, generators, heating oil systems, and similar machinery that runs on gas oil (red diesel)
