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.Read full review...
