Fuel Injection Cleaner: Needless upsell

Automotive Tip of the Week: Fuel Injection cleaner is generally a complete rip off. Most modern gasoline's already carry cleaning additives and detergents in them that are quite effective at maintaining (and even improving/cleaning) the fuel injection system. For all the bad things that go along with it, ethanol does also provide some reasonable cleaning effects. Fuel Injection cleaner is really only useful for very poorly maintained vehicles, or ones that have sat for a long time and need an extra kick in the pants to get rid of varnishing from aging. Any daily driven vehicle from the 90's forward will essentially never need the additive. Save your money!
