RE: Gas ques...

If you run a bit more timing, it may require you run higher octane fuel to avoid pinging

RE: Gas ques...

if ur stock motor with stock timing, run 87

runing higher octane than is needed is just wasting money and making ur car crappier

Putting premium fuel in a car that does not need it WILL NOT increase hp... not even 1 hp...

higher octane fuel is used to control burn... it doesnt ad anything... if youre running high compression and/or other mods then you may need higher octane fuel to control the burn... nevertheless, you DO NOT need higher octane gas in most stock engines an simply putting a higher octane fuel in your tank will do ABSOLUTELY NOTHING FOR YOU except rob your pocketbook... no hp gains...
