    Awesome product. I wish I had found it years ago, it would have saved me a lot of time and expence with all my engines from garden tools to automotive. I have just tested it in my diesel heater and within minutes it went from smoking out the exhaust to clean and clear with no unburnt fuel smell even on the lowest setting. I have never been able to use the lowest setting before because of the smoke. Fuel Doctor pays for itself in maintenance and repair savings.

    I find the Fuel Doctor is a great product.I’ve been using it for 10,000Ks and it has lowered my mileage by .5 to 1 Lt per 100ks.Plus keeping the fuel system clean. The 5 lt pack is the cheapest option.3 days for delivery which is excellent .

  • Would'nt fuel up with out it.

    Great Product, since using Fuel Doctor I havn't had any fuel injector problems, Running Hilux's in rural W.A. , fuel quality is not the best, prior to using this product I have had Injectors replaced 3 times and an engine failure at 67000km's , from new, Have had no problems since using this product. Its not exactly cheap, but hunt around on ebay for a good price. I use it religiously in all my gear ,Diesel, petrol, and the 2stroke chainsaw.
