Hey guys the 3.6 definitely doesn't fare too well with the 87 octane . One full fill up of 93 and there's no more pinging. So much for the recommended stuff

Maybe try a different brand fuel.
I put shell 87 on my 21jlur and haven’t had any issues so far.
Since I bought mine about 10 months ago , it didn't matter what brand went in and it was always 87 but always pinged below 2000 RPM . Did a 93 octane full fill-up ...no pings

I put a variety of different brands of 87 in mine. I upped the game to 35's and did not change gears. 3000 miles so far and I have not heard any pinging.

Just wondering-any chance you’re not revving the motor out enough? That’ll make one ping every time.

Might try a different gas station then. I have had my 3.6 2020 JLUR since Sept 2019 and she has been running fine at 87 Octane. Does she have a drinking problem at 17.5 MPG? Absolutely yes. But she runs like a champ at 87 Octane.

I have tried 93 Octane once or twice and noticed no difference. Given the fact that 93 can cost upto a buck fifty more per gallon here on Long Island, I am happy sticking to 87 Octane.

I don't think I lugging the engine I basically drive in the RPM range that n automatic would be at that speed.

When full throttle I rev out but @ rolling speed I keep the RPMs low. Oddly between 1000 -2000 RPM torque is bit uneven or one could say jerky .. Other makes are nothing like this the torque is more linear.

In my travels I never restricted myself to one brand but never noticed a difference between the brands either . This is the first time I dumped some extra cash into the tank ..to put it short mine doesn't seem to like the 87

Do any mods to it esp the engine? Mine is factory stock still and will probably stay that way for as long as I own it.

all factory... including wheels... I truly believe at this point that its running lean @ part throttle in 1000 -2000 range.
Anything above 2000 RPM including when running on 87 is smooth but running below that range it jerks a bit often.
