Gas Engine Injector Cleaners

[DocHeb]

Back a while ago when I worked in GM shops they did not recommand any additives as they could harm injectors.You may want to read the owners man.

Do you have any insight into what my local dealer is doing for their "$189 Fuel System Tuneup", which includes "replacing the fuel filter, clean fuel injection, throttle, body & de-carbon combustion chamber (sic)"?

I use Marvel oil both in my tractor [diesel] and my chevy van [gas].

My Dad said that ATF in the fuel would keep injectors clean, I add a quart every couple months in all of the fuel injected engines that I own. Never had an injector issue. Just pour into the gas tank. Cheap enough but your mileage may vary.

Pass on the ATF, that's the last thing you want to run through your injectors. ATF contains friction modifiers that are beneficial to an automatic transmission, but detrimental to injectors or fuel system components. ATF will actually increase the wear in ways that are worse than just running plain, untreated fuel.

As far as gas treatments, if I was looking for a regular injector cleaner I would go with sea-foam.
