What additive is best for me to I use in my fuel to clean the throttle body, valves, etc. and how often. I have an 03 trailblazer 6cyl and an 04 silverado v8. Thanks

i have had good luck with Red Line it is a detergent too and doesnt use solvents that could harm seals , o-rings and gaskets.

Is red line the brand name and where is it available? Thanks

Red Line is the brand yes...and here in central texas i have only found it in Pep Boys. May be else where in other states though.

I've also been using RedLine and it seems to work well.

I like SeaFoam. It is available at any Napa Auto Parts Store. I also have tried Red Line it is also an excellent product; however it is not available in the local parts store here in Bicknell!

buy a spray can of 3M throttle body and choke cleaner and with the butterfly open all the way, spray a lil bit down there and then start it and work the butterfly and spray to keep it running until the can is empty......i would do additive, gums up fuel tank, lines etc.
