Fwiw I come from forums where we kinda talk shit while also talking cars so sorry if I came off a little abrasive. I forget some other forums aren't that way.Mostly it is q daily, not a toy. It will get what it needs to perform the most efficient (based on mileage, engine life, and cost). I don't care if it is fast, I got other stuff for that. It just seems a little odd how jeep jut it. Mostly if over 95 been getting premium. If pulling, definitely premium (those two instances are displayed in manual as a must I think).
When premium is within about .30 for it, premium. But some places want as much as a dollar more...then 87. It does get a majority of top tier gas for the detergent. When not top tier, definitely 91. It won't make up for the missing detergent, but hopefully a little less nasty build up if timing being used to full advantage.
I guess the curiosity is, how much timing is being pulled? And how much does that effect turbo (as again, first boosted car)? I know on my ls2, if timing bus pulled, it is a lot and I can certainly tell. On this, I haven't seen much. Maybe a bit more lag in the turbo, but I also wonder if that is in my head as I am looking for it.
P.s. grand national.... sweet ride.
Anyway if you have an obd tool we can test it. I am sure it pulls boost. I am not sure if my obd mx can log timing but i will give it a shot as I've wanted to see what kind of boost it makes. If I can log timing and boost on a similar 95-100 degree day (plenty here in Dallas) maybe I can see how it compares to yours on 87.
And yeah it's my wife's daily. Mine is now her old turbo mini and my s2000 is now the toy.
I've never owned a car that took anything other than premium so I have always just hit 93 and went on my way.
