I was wondering if you are running regular gas then switch up, would that hurt your engine??? Or if you just keep on switching gases...

 

It shouldn't hurt, but why do you wanna keep switching?

 

your wasting money if your useing anything more then 87 without needing it...

 

Im not saying it like that I meant if i used regular for awhile then premium for a bit and went back after awhile, if that would have any harm done

 

I cant see where it would be "bad" for your car, but why would you want to spend the money for premium if you didnt need it?

 

No, it would not hurt.

 

yesterday i got gas and since it went down a lil and i had some cast i put the 93 oct. in (norm. 87) just to see if it actually made a difference...............it dint. wel that i i could notice anyways. it might have ideled a littler better tho.

 

I use 87 since im not running boost yet. Gas prices are killer. Only time I use higher is when I have no choice and im at sh*ty looking gas station then ill drop mid to high octane feel safer.
