Gumout Fuel System Cleaner

http://www.vipauto.com/pages/fuelsystemcleaning.html

I have run only Chevron 93 octane fuel for over 100k and sometimes used Techron injector cleaner.

Do I need this?

No, it is too weak to really make a difference, The best way to clean injectors is with the pressurized system that alot of dealers use.

Thanks.

Any one else care to chime in on how they clean there injectors?
