Thanks.

If by 91 you mean Premium, then yes. simply open your gas tank and it says it right there.

 

There's this thing.. Its at the top of the page.... it says SEARCH!


But on the other had, i would say yes. Why risk it? If you can afford the payment for a G you should be able to spend an extra buck or 2 on gas. Just do a search for it and you will find plenty of threads where this topic has been beaten to death. Everyone's got thier own oppenion on it.

 

let's be reasonable here, saving money from using 91 to 89 octane is usually a difference of 5-10 cents in philly, so if you fill 20 gallons, all you are saving is $1-2 dollars. Is $1-2 dollars per fill up really going to affect you that much?

If you want to save money on gas, changing your driving habits makes a big difference. I get 18mpg on my civic for highway/city (because of the way I drive), but when I do long trips to other places, i can get as much as 38mpg.

 

Yes you should use 91, it's what your ECU is mapped to
