I'm just curious what grade fuel everyone uses. I have a 3.7 and I was using 87 for a while. One day I was running on fumes and I rolled into the gas station and I decided to splurge on 95. Oh what a difference! It runs smoother and idels quiter, and shifts better. For the .20 per gallon difference it's worth it IMO. I know it's only a 3.7 so every little bit helps. LOL
I noticed almost immediately when i bought my WK that it kinda ran rough on 87, tried it for a while and it was ok but not perfect. Tried 89 for a while and its much smoother. That and a master jeep tech recommended it for the 4.7. The little pamphlet that was in my owners manual also says to use 89.
For the 10cents more per gallon id rather have the 89. and supposedly there is less ethanol the higher grade you go and ethanol on non flexfuel engines even in the small 10% quanity they put in gas can still screw up sensors and other seals and such in any engine.
I try to only buy from Irving or Cumberland farms/Gulf or HESS
6.1L / 93 Octane / Exxon, Shell V-Power or Amoco Ultimate / Why?.....Only the best for my baby. Plus, the Diablo said to use 93 or higher for the canned tune I put in.
I always use 87, but have used 89 and 93 a couple of times in the past.
I wonder if any harm can be caused by using a higher octane on vehicles that only call for regular. I kind of want to try using a higher octane on my next fill up to see if I notice any big differences.

Anyone able to find ethanol-free gas where they are?
There is a convenience store right next to my subdivision and they have ethanol-free gas. I can definitely tell a difference when I fill up with 93 as compared to when I fill up at a station that has "up to 10% ethanol".
