Red Line SI-1 has the highest % of PolyEther Amine's @ 30-50%. This is what cleans the fuel system. Chevron Techron Fuel system Cleaner is a close second. The Chevron Fuel Injection Cleaner posted above isn't that good. Most fuel system cleaners on the market are mostly Naphtha, which is pretty much just a solvent.
How about adding a bottle of seafoam to the tank. The bottle says it cleans and lubes the entire system. Probably not bad for our injectors.
Sounds easy enough. But would that be safe?
Close to this topic but, some guy at work said you could put the regular gas into a car and just put fuel injector cleaner in it and it's the same as the supreme type gas. Is that True?
