It makes logical sense to use 93 over anything else IMO. i mean the difference in price to full up would prolly be 3 or 4 bucks so why not use whats recommended?

^ since you put it like that i did the math and your right..its usually .20 to .30 more cent a gallon..at .30 16 gallons would be almost 5 bucks..

i think ill seafoam the gas again and run 93 from now on again..i did this before but stopped after a few months when money got worse but looking at it like this it really doesnt matter in price that much.

to be honest I almost always use 89 and I have had no issues whatsoever, been about a year now.

Also to whoever said higher octane doesnt equal better performance im not trying to debate you or say your wrong but when I put 91 or 93 I do forsure notice a positive difference in performance.

I use nothing but Sunoco Premium gas here in NJ. It's winter, I haven't driven her much, so just put in 91, but in rest of the seasons I use 93. With prices rising tho...I think I might just stick to 91 year round? :X

Anyone interested in octane should read "octane ratings " in Wikipedia. It tells it all. It's full of info. A must read.
