besides running 93 gas, has anybody noticed a brand of gas, like shell, citgo, exxon, bp that seems to perform better than others and how does everybody feel about fuel additives like octane boosters, injector cleaners, upper intake cleaners and that lot? i personally use 93 from whatever gas station is near by when low on fuel but i have always wondered.

 

93 for me as well, nothing less. I like to run a bottle of injector cleaner at every other fill up, I would run octane booster but I don't see much of a point when I already have 93 in it and don't run my Z at the track yet. Otherwise I probably would.

 

I prefer Sunoco myself.
