Hello drivers, lets talk about fuel. Fuel, whether gasoline or diesel, is delivered to your car, truck, SUV, minivan, or fleet vehicle engine to be burned to generate the power needed to keep you moving. This fuel leaves a residue as it moves through your fuel system. This may not seem like much, but it can cause big problems. Gum and varnish build up inside fuel lines, your throttle body and injectors. It’s like plaque build-up in your arteries – it restricts the free flow of fuel and can even clog your vehicle fuel injectors.
