Hello fellow Jeepers. I'm new to the Jeep world. Just purchased my first Jeep a week ago. 2020 Wrangler JL 2.0 turbo. I had to fill it up for the first time today. I used 87 octane after reading the book. It says to use 91 when towing or extreme heat. I'm in southern Louisiana. It's always extreme heat here :LOL: but I'm sure not extreme as the book is talking about. My question is, what do you guys use.

I use 91 because of the turbo. My understanding is that the fuel is cleaner so better for the turbo.

Thanks!! I guess filling it up with 83 won't hurt this time. I'll try 91 next fill. Thanks!!!

We also bought a 2020 2.0L turbo last month. I know the owner's manual says that 87 octane can be used for satisfactory performance and fuel economy it says that 91 octane will allow it to operate at optimal performance. Thus, we fill it with 91 octane.

I run 93 through my 2.0 because its only $1.65/gallon. For that price i can top off for less than $30.

Thank you very much for the reply. I’m going to start using 91 also. I’ve read sometimes you’ll hear a knocking using the higher octane and if so use lower octane. Just wanted to share that with you.

Regular will pre ignite due to the excess heat created with a turbo. Super does not. In my opinion you will never EVER experience "knocking" (preignition) on super over regular.
Jeep does not seem to mind preignition. I am not a fan. To me, if it ignites early, it is affecting the power stroke, therefor affecting the power generated. I would not waste my money on anything but super with a turbo. If you want to save a bit, use mid grade.
