I put some seafoam in my gas every 5K or so.... keeps stuff clean

 

 

I use 91 in my truck. They don't offer 93 or 105 unless I go to a 76 station. It seems to work fine, and I don't have anything major done to my truck except for the bolt on's and a tune. I was curious about the boosters when I asked the question. If I buy any cleaning agents or boosters, it would be from Lucas. I read an artical one day, and it was saying that Lucas was the only one that really works. All the others may look good on the bottles, but nothing worth a crap on the inside. I think it was in one of the NHRA mag's. I'm off to get me some BG from the stealership.
