Any turbo engine needs higher octane gas for peak performance. Dealer told me regular was ok....Nope. Switched o 93 octane and never looked back. Engine gives you that spirited turbo whistle that I personally love.Interesting results. Seems like so far almost 2 out of 3 are using premium gas.
Been doing a lot of reading old threads and researching on this and thoughts seem to be all over the board. It seems basically though that with these turbo charged engines, there probably is some benefit to using higher octane gas although people will also do just fine running 87 gas.
Seems like it's pretty tough to quantify the benefit but most stuff I've seen seems to suggest there is likely some benefit even if it's not noticeable. Seems to me at the very least you're not making these turbo engines work quite as hard when you feed them better octane gas even if performance differences in mileage or power aren't noticed. I mean, I know the engine is built to compensate for lower octane gas but common sense would suggest to me that if you don't need to make the engine do that compensation work, it's probably better for the engine in the long haul.
There has to be something to be said for the fact that the manuals for the 2.0T engines in the Wrangler a couple years ago were written to recommend 91 octane gas but then later were changed to say that 87 was okay but 91 is recommended for peak performance.
I think I'll probably be opting for some higher grade just for piece of mind since I plan to keep this vehicle for awhile. I'll have to see what pumps have around me even have. If they have 91, I'll probably use that. If not, I'll probably use at least 89 just for a little extra piece of mind....or maybe alternate 89 and 93.
I guess I look at it sorta like the human body and taking daily vitamins or something. You don't need them to run, but they can help you run at peak performance.
