Higher Octane

Which type of gas do I put in my 1996 Acura Integra Special Edition?

should be fine w/ 91 octane. ur compression isn't too high, so the higher octane really isn't needed, but still, i'd keep w/ the middle grade cuz the 89 is well...junk.

I agree. My friend has an LS and he hasn't had problems with the cheap sh** but when I used that sh** by mistake it ran like shit and was ping'n like a bit**. Id say you get what you pay for.
