Each diesel fuel additive in this range is carefully chosen and designed to keep your diesel vehicle in top condition. By regularly using these products, you’ll be cleaning your fuel injectors and helping your engine run more efficiently, reducing the risk of damage and boosting fuel economy.

This range also includes a premium cetane booster collection. Diesel Cetane Boosters raise the cetane number of diesel fuel up to seven points for maximum horsepower, increased fuel economy, and easier starts in all diesel engines. Diesel engines operate best on fuel with cetane values of 50 or higher. By increasing cetane, diesel cetane boosters improve the ignition quality of diesel fuel, maximizing available power and improving starting. It also smooths idling and reduces smoke and emissions. As well as cetane boosters and fuel system cleaners, we also have additives to help with cleaning your DPF and maintaining your Adblue system.

We stock cetane boosters and fuel additives for diesel motors from trusted brands like LIQUI MOLY, Millers Oils, and Red Line, all formulated to work in even the toughest conditions.

If you want to keep your diesel engine running at its best, don’t forget to explore our full range of oils and fluids for engine oil, gearbox oil, power steering fluid, screen wash, and more.
