The potential for purchasing contaminated fuel is always present. An alarming amount of fuel storage tanks have some form of contamination or “dirty fuel”. How much and whether it will affect your vehicle depends on a lot of factors: age of the tank, lack of appropriate maintenance, temperature, volume of residual water, where the fuel came from, how long it’s been there, and of course when the tank was last filled. Because you can’t see what goes into your fuel tank, you run the risk of transferring contaminants into your fuel system and causing damage to your engine, every time you fill up.
If you value optimal performance from your vehicle and longevity of your engine, and don’t want the expense of replacing prematurely corroded and damaged components, then you need to use Fuel Doctor to treat and maintain your vehicle’s fuel system.
