What grade of gasoline octane do you use & Why? Also state what size motor?
 
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 use 89.

2005 non flex fuel 4.7 V8.

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

I use 93 or 95 depending on whats available. I usually go to Hess, Sunoco, or I hate to say it Gulf.

I use ethanol-free 93... running the SuperChips 91 tune, but 91 isn't sold around here - only 87/89/93. I've got the Hemi.

Before I got the tune I was running 89.

93
2007 4.7

Reason: Running superchips 91 octane tune, 91 is not sold around here so I have to go with 93.

Other for me...

I use 99, only the best for my baby! Pity I only have a '91 tune though...:lol:

Edit: Just read the title... Engine is a 4.7L and I use 99 as it's only slightly more expensive than regular (95).

Why the hate on Gulf? They and Hess are some of the few that dont get gas from the middle east.

Our regular is 95 and its only pennies extra for 99 (Shell V-Power).

A few gas stations here sell 102!! That is about 1.5x the price of 99 though! :eek:

Isn't Gulf owned by Exxon/Mobile? Half of the Exxon's and Mobile's by me turned to Gulf stations...

I think Gulf bought out exxon.mobile. We barely have any exxon or mobile stations any more.
