I am using premium, 93 octane. My dealer put 81 octane in it and said there would not be any problems burning regular. But I think I have a little more pep, and my mpg seems better with 93 octane. I am avg. about 25 mpg.LTDANMAN44 said:

93 supreme in my S2000.
I thought about this for some time and decided to just use regular gas at 87 octane. The car runs great The engine is just a 4 cylinder and not some exotic engine so I am not worriedLTDANMAN44 said:
The owners manual states that you may hear knocking from using low octane, but that is normal. I noticed that at low speeds especially, during my first tank of cheap stuff from the dealer. It seems to have gone away since I switched to premium. The power is noticeably better, as is the mileage. Since this engine is tuned to run best on premium, and does so with increased power and mileage, I think it is just as, if not more, cost-effective with the recommended fuel.oregon solstice said:I thought about this for some time and decided to just use regular gas at 87 octane.

ryankely said:I aree the car will run better on high octane,but as for which company to buy the gas from makes no difference,gas is gas is gas,buy it from the company that sells it the cheapist. (my best buddy owns a gas station,it all comes from the same place)
It depends on what's in that racing gas. If it has lead in it as an anti-knock compound (technically called tetraethyl lead), it's a definite no go, but I don't think you can get that any more.OZ40 said:Premium, why you young whipper-snappers, in my day we called it Hi-Test or Ethyl. I put in 94 octane and I feel I get more power and better mileage. There is a station on the corner that sells racing gas, 106 octane..do I dare? Would it hurt?
