I'm a broke 17 year old with a 1987 gt. Should I really be spending the extra to get premium? It is totally stock and isn't raced.
I wouldn't spend the money. No need for It unless you are modded and tuned for it. Just make sure you are getting gas from quality places. Gas from Bob's discount filling station is usually a bad idea. Stick to places like Chevron, Shell and BP etc.
^This is what suggest.With a push rod motor a tune is not a huge deal as you can crank up the timing the old fashioned way with the dizzy to 14* and wake that beast up with some 93
Yeah mine is bone stock and say to use unleaded fuel only. Nothing about premium.Rosco said:If you have a high compression car then typically you are required to run premium in order to avoid detonation. Octane has to deal with how much the fuel can be compressed be for it detonates. Your dash should tell you if you need it, usually it says "use premium unleaded fuel only" if that's the case. If your engine has been modded, ie forced induction, block work or aggressive tune may require you to use it. If you don't need to run premium I don't see the point in why you would.
