The last 2 fill ups with my Gov. 06 Impala 3.5 v6 has been with Shell and I have noticed a difference in the acceleration and pep. I haven't had a chance to try it in the Stang yet, but was wondering if anyone else is using Shell and noticed a difference in performance?

 

I took a trip to Dallas,Tx last weekend and ran Shell fuel the whole trip and had no issues. I did notice a big gain in performance prolly just because of the drop in altitude.I went from 5,418ft to about 800ft in altitude. Love that oxygen!

 

I use Shell 93 or Chevron gas 93 on every fill-up.

 

No difference here. My car doesn't exactly like Shell (or at least, my old tune didn't), but it's the only place within 5 miles that sells 93.

 

I thought shell was supposed to be really good stuff? Thats what I always use, the 93 V-powa!!

 

The only difference I notice is my wallet tends to be lighter than if I went someplace else.

 

It is one of the better fuels, but the alcohol content messes with my AFR a bit... At least, it did on my old tune. I haven't been to the dyno since I changed tunes.

 

I always pick shell first... if I can't find it, I'll go somewhere else.

 

My car doesn't like the Shell 93 either..lol
First time I tried it, I just thought I had gotten some bad gas.
Second time, I said no more. For some reason my car really loves
Chevron. Exxon runs good...but something about the Chevron gas.

 

Mine likes BP but the ones close to me went down to 91.
