Over time, Bad fuel & contamination can cause a build-up in your fuel system. Clogging your Fuel lines, Filters and Injectors.
This can lead to poor performance, Mileage and eventual failure of your engine. Fuel grades, fuel lines, filters and related components can degrade over time.
When filling up at the pump you may sometimes introduce contamination from the filler neck or the fuel going in.
