The Best Fuel System Cleaner- And Do I Need It?

There’s been a long debate about whether fuel system cleaners really do anything or whether they’re just another product sold by big names. Truthfully, the theory behind fuel system and fuel injector cleaners are solid.

In a typical combustion engine, gasoline needs to be burned to release the energy that is stored within. It’s this chemical reaction that powers your engine and, thus, your vehicle. While most of the residue is expelled through your exhaust pipe, nothing works perfectly. There are solid products left behind in your engine and fuel system, which can lead to a buildup.

Fuel system cleaners seek to eliminate this buildup by adding a product to your fuel system. This is where you will find terms such as ‘best fuel additive’, ‘ cleaning fuel injectors additives’ and ‘best gas treatment’ baded about. It essentially means the same as saying, “top rated fuel injector cleaner” but it’s just a different terminology.

The chemical buildup that tends to be left behind in your fuel system is known as a carboxyl compound, something that your average cleaner will not be able to remove. It’s for this reason that fuel system cleaners are so important: Since these cleaners are specifically designed to clean your fuel system and injector, they’re made with a chemical known as polyetheramine or PEA.

The beauty of PEA — which is also known by the patented name Techron — is that it’s specially designed to break down these deposits, making them your secret weapon with it comes to cleaning your fuel system! Some of the top rated fuel injector cleaner products come with, and some without, but for best results, 90% of vehicles will perform better ‘with PEA’.
