[QUOTE="SRAD97750, post: 170352, member: 425"] Anything under ~200PSI cranking compression (~14:1 compression) will not be able to use a higher octane fuel without massive timing advance. In most cases it will actually cost you horsepower, as the engine can't ignite the fuel fast enough. The fuel has a higher energy content per mass, which requires higher pressures. Do a cold compression test, if your engine isn't pushing 180+ PSI, you're wasting money with anything over 95 octane. -BIG DAN:thumb: [/QUOTE]
