Which octane do you use in your 1.4T Cruze?

[StoneCrab]

What grade of gas do you regularly or most often choose for your 1.4T Cruze?
Regular, mid-grade, or premium are the choices, since actual octrane numbers vary from state to state for the various level. Usually regular is 87 octane, mid-grade is 89, premium is 91-93.

regular.....and the cheapest i can find.

I use regular all the time and have no problems using it.

Premium 93 from Shell or BP for me... I'll soon be Trifecta tuned and be required to use 93 anyway.

I sure didn't buy a fuel miser to put premium in it!

Premium. It does get better fuel economy and power over regular unleaded.

Only Premium 93 from Shell/BP for me. Absolutely senseless to run a turbo-charged motor on regular 87 to save $2.00 per fillup.

When I first got my vehicle I ran one tank of 87 through it. I noticed more vibration from the engine at lower rpms. After that tank I went to 93 this has been my 3rd tank of 93 and the vibrations are pretty well gone. Have'nt really seen any mpg improvements as some have stated but I don't think you would notice it anyways.( since there are so many different variables that come in to play with mpg) I've been avg 31mpg do to 90% city/hills and 10% highway .

I'm sad to see so many people running 87 when even GM confirmed you should run at least midgrade in the summer.. 89 should be a minimum year round though, its a lot safer and better for this platform than 87, it's a mere $1.00-1.50 more per fillup for better mileage, better timing (small bump in power), and safer for the forced induction motor

Where did they say you should run 89? I never got notified about that.
