“I have religiously used Fuel Doctor in my 80 Series Landcruiser for around 15 years, recent complete draining of both tanks via the bottom drain plugs revealed absolutely no foreign matter present either in the form of water or other contaminants – a great result!!!!

At more than 330 000 km on the original injectors the engine still starts instantly

It blows virtually no smoke and still gives great economy and performance – a great result!!!! ” – David from Sydney
