Put seafoam in my gas tank last night. For those of you that have done it this way, do you recall what you noticed and how long did it take. I had a tune up last week so didn't want to risk fouling up my new plugs.

Put a can in the tank of the Yukon I bought and drove it from NC to Orlando, Fla.....didn't have any problems nor have I had any since.

I pulled 3 plugs when I got back and they looked fine......

The only reason I did the Seafoam strictly through the tank, was the fact that the dealership I had it at before my trip for warranty work, suggested an injector cleaning service. $185.....thought I'd spend $8 instead.

I did the 1/2 in the tank, 1/2 through the vacuum on my tahoe back @ 90K, and changed plugs and wires after that, but the plugs that came out didn't look bad at all.
