Once again, using an octane higher than what is recommended in the owner's manual does absolutely nothing to increase performance if it was not tuned for it. Perhaps you think you know more than the engineers who designed your Jeep. The placebo effect is strong with this one, Yoda.

Yes, I read the entire thread. Did you?
If My Car Recommends Regular Gas, Is It Good to Use Premium Occasionally?
If you burn premium because you think it makes the engine peppier, that is probably psychological: “I’m paying more for gasoline, so I must be getting more.” Some motorists claim...
If the Toledo plant does it similar to a competitor's assembly plant that I'm familiar with, the vehicle still goes through the paint process with the doors attached. Thus, no paint between the hinges and body.
When it exits the paint department the doors are removed so that it makes things...
Using anything higher than what is recommended in the owner's manual is a complete waste of money and serves absolutely no performance gains. Of course, there's always the good old placebo effect. Some owners apparently don't mind spend a few extra dollars per tank for that.
Well, we're old whippersnappers in our 60s and ours gets filled with 87. If 87 octane caused any problems to the 2.0 engine the engineers would not have stated in the owner's manual that it was OK to use. We plan on keeping it for at least 10+ years.
It can be, under the right circumstances. A co-worker of mine bought a house in 2020 that he says is 5 minutes from the entrance to Disneyworld. He lives in Missouri and bought it to rent out for $350/night to Orlando area vacationers. He told me yesterday that business is booming.

Tom Winkels. He saved me over $1,500 off what my local dealer wanted for the exact same warranty for our old JK. When I showed them Tom's quote they said it was lower than their cost (it wasn't) and they would not match it. I bought it from Tom and it more than paid for itself for the 7.5...
Ask them to show you where it says to do that in the maintenance schedule of your owner's manual. It's not there. That should tell you whether or not it should be done.
My wife says the leather seats in her '20 JLU Recon are comfortable. It's been her dd for two years and 30k miles so far. I would have heard about it by now. She previously drove a 2013 JK with cloth seats.
Why do you feel you need to add an octane booster? Your owner's manual says that 87 octane can safely be used in the 2.0T. My wife fills her 2.0T JLU with 87 all the time because the way she drives she would not benefit from the higher price 91.
