Back when I was in Puerto Rico, all there was was 89 and 93 Octane fuel and I used 89 on my Jeep, now that the Jeep is about to arrive here in Jacksonville Florida, I see that there is also 87 octane gas in some places. What are you guys running? should I stick with 89 Octane or is 87 OK? Thanks for the answers...

no benefit in running 89 over 87.

87 is all I ever run. Never had a problem.
