I agree! The FCA engineers designed the engine around 87 octane fuel, and running around town in anything higher is wasting your money. The FCA engineers are trying to keep the Jeep alive while keeping to government regulations.I feed our dogs top shelf foods, luckily our Jeep runs fine on top-tier 87 octane. Like I mentioned earlier, if I can find crapanol-free gas I'm all over it, but unfortunately it's only available on our road trips, not locally
If I'm going to spend all day at low RPMs doing silly stuff off-road in my Jeep with the windows down, it may be worth putting in 93 to lose the annoying pings. It may in-fact have no effect. I'll find out the next day out in the sand.
