Not unless its throwing a code. All autozone will do is read the computer if theres a check engine light on.

Just run that tank of gas all the way down till the mix is gone. I've always used 87 and I noticed my car sort of put putted at one point. I think it was bad gas; it eventually went away on its own.

I have flowmaster exhaust and a K&N , That bullsyht by the way , ive run my car w/ 87 and run it with 93 , i CAN tell the difference even if its only slightly. maybe its bad gas but when 3 + people tell u it doesnt mix well , im gunna say ur the odd man in it
So if you know everything, and have 3+ expert opinions, why are you asking questions? [&:]

like everyone else is saying, the only reason they make supreme gas is for those cars that have hight compression that need it to prevent early detonation. unless you up your compression or advance your timing or lean out your AF ratio (AKA get a tuner or chip) 93 octane is giving you no benifit, in fact all that extra stuff not being burned will eventually just clog up your engine (Over a very long period of time)
