Fuel Doctor is a unique, industry-leading fuel conditioner and injector cleaner, which provides quality assurance for your fuel and protection for your entire fuel system. It works on all diesel, petrol, and two-stroke engines, including cars, motorbikes, trucks, busses, boats, mowers, anything that runs on these fuel types. It will also stabilise and extend the life of fuel in storage tanks for up to 2 years (petrol) and up to 5 years (diesel).

Fuel Doctor is the only fuel conditioner developed and used by professional fuel tank cleaners on a daily basis and is proven to work in any size tank, in any vehicle. It treats water/condensation and fungal growth contamination, plus the effects of gums, varnish, and the typical bottom-of-the-tank sludge that develops over time.

In addition to treating and cleaning the fuel and your tank, Fuel Doctor also cleans, lubricates, and protects every part of your fuel system including fuel lines, fuel pumps, injectors, valves, seals, fuel and particulate filters, and cylinders.

So use Fuel Doctor to clean your system thoroughly during the “shock treatment” stage, then maintain a clean fuel delivery process via the maintenance treatments and start your engine with confidence.
