Yeah, but that couple of bucks will pay for the higher octane fuel also. I put 93 in my car and my wifes B9. For the B9, a 16.9 gallon tank if I am not mistaken, a tank full of 87 would be about $47.15 where a tank of 93 would be $50.53. A difference of $3.38. This is based on $.20 increase from the low octane to the high. I think it is well worth the extra couple of bucks to have your engine run the way it is supposed to.
