What octane level?

Another question to dovetail into the PO's original question. The gas station I regularly visit has ethanol free gas as well. A little more expensive of course. Any benefits to using it in tj's? Couldn't find a clear answer looking thru previous threads.

I have never seen or felt enough of a difference to seek out ethanol free.
 
Thanks for the response everyone. Looks like 87 it is (we're 87-89-93 for the most part in this area).
 
I've never used 87 octand except on my lawnmower

87 is good for your Jeep and lawn mower. ;)

Since the conversation is evolving a little. Daily driving I use ethanol blended but in my cars that sit more often exspecially through the winter months non-ethanol blend. Better shelf life without the corn additive.
Speaking of additives. seems to be past marketing would claim the higher grades had the better additives… don’t see that promoted much anymore around here. Anyone else know if you move up in grades you get more detergent as well or no?

Interesting idea about using ethanol free in cars that sit a long time.

I do the same with my Camaro, ATVs and mowers.

Jeep usually gets mid. My old Cherokee (1998) seemed to really prefer the mid grade gas. I stuck to that with the LJ but will start using regular for a while and see if I notice any difference after reading through this thread.

Our Cheorkees ( 94 , 99 , 2000 ) were much more likely to ping over our TJ's. we used mid grade in them.
 
87 usually. Ethanol free when stored for extended periods. And on longer roadtrips in high heat or under high load I may up to midgrade.
