The Gumout Fuel Injector Cleaner is intended to eliminate carbon buildup from significant engine components. It does an impressive job of returning your fuel injectors to their former splendor. However, it will continue to function to stop more carbon buildup on your fuel injectors, intake valves, and ports.

This approach is safe for forced induction engines to employ, is oxygen sensor safe, and should work to lessen emissions while marginally enhancing fuel efficiency and performance.

Picking the Best Fuel Injector Cleaners

Now that you’ve read about the best fuel injector cleaners, it’s fitting to know more tips about picking what’s best for your needs. One of the factors that you need to consider is that you should always check if you’re choosing a product that contains Polyetheramine (PEA). This is considered as the strongest cleaning agent. Some cleaners contain Polyisobutene (PIB) or Polyisobutylene amine (PIBA), but they are not as potent as Polyetheramine. You’ll be surprised that some older fuel injector cleaners contain alcohol. They put it there for water removal reasons. However, don’t purchase these old options as they can damage fuel system parts, and you should avoid them at all costs.
