I loved the 3.6 in my 14 JKU. But I test drove the 2.0 it felt like the motor was running at redline just driving around town, needless to say I got another 3.6
I have driven my 2.0T for almost 3 years and not once have I ever been close to redline.I loved the 3.6 in my 14 JKU. But I test drove the 2.0 it felt like the motor was running at redline just driving around town, needless to say I got another 3.6
To quote the user manual:Your dealer apparently hasn’t read the specs for that engine.
The 2.0's drop in performance is due to the tune altering ignition/fueling/etc. and not a direct result of the lower octane's burning characteristics. All(?) modern engines have knock sensors anyway, so I'm not quire sure how pre-ignition damage would occur.If I was buying a 2021 I would get the turbo to skip the etorque. But then I though about the high octane gas. I know it says it can take low octane, but the manual still says it performs better on high octane. I go back to my undergrad days at engineering school when we studied the combustion engine. We studied turbocharging and the reasons you need higher octane gas when forcing all that compressed air. It means you need gasoline that takes more heat to ignite (higher octane). Your engine wont blow up during your warranty period, but I cant think long term use of low octane gasoline on your turbo engine has no consequences. Think about it, manual still says it will perform better with high octane gas, and so does science. For those of you planning to keep the 2.0 past warranty and using 87, how do you sleep at night?
yeah read my edit. Few minutes before your post lol.The 2.0's drop in performance is due to the tune altering ignition/fueling/etc. and not a direct result of the lower octane's burning characteristics.

If anything, the 3.6's higher redline combined with it's 11.3:1 compression ratio makes me far more concerned than de-tuning a 2.0 to run on 87.
Haha, serves you right for doing research. I hope you've learned your lesson! ;Dedit: So I look the compression ratios for both engines and the V6 has a higher compression ratio than i4. In fact, the V6 compression is pretty high and engines with these ratios recommend higher octane gasoline. So the computer in our V6 JL ia probably doing a lot of work to avoid knocking. The i4 is probably doing the same. So we are all on the same boat. Well, now I cant sleep at night . Fack.
They both take 87 octane.I think they are both really good motors. I don't think you should generate any regrets either way. I ordered the 3.6 because I wanted a manual transmission so I didn't have to choose. However, I think I would be just as happy with a 2.0.
