Fuel Doctor Fuel Conditioner can be used with all petrol and diesel fuels, with absolutely no detrimental effects to the associated engines or fuel systems.

In fact, the manufacturers, Fuel Doctors™, have never seen any adverse effects from using Fuel Doctor with other fuels such as two-stroke, E10, E85, Methanol, and Avgas. And it’s perfectly fine to use Fuel Doctor with dual fuel vehicles that use petrol or diesel with LPG.

AdBlue® is also not affected by the use of Fuel Doctor.
