whenever im about to get my car tuned i run premium gas for a while then always after the tune, is this a waste? im only runnin like 7-10 psi

 

I would never run anything less then 92 or 93 on anything F/I no matter what psi number or nitrous shot size but maybe thats just me.I was under the impression to prevent detonation and knock you had to(or at least it was recomended) use 92+gas.

 

stick with the premium. it's pointless to use less. you only pay like 5 bucks more at the pump. if you think about it it's only like a pack of cigs.

 

my car runs like ---- with anything but premium gas in it...

 

ive always run premium on only 8psi. better safe than stranded

 

always premium with FI anything less has a very good chance of detonation, I usually run a 50/50 mix of 91 octane pump, and 100 octane fuel in the crx and thats 8 psi, may be overkill, but the motor loves it.

 

I don't even run anything less than 92 octane in my N/A B16. I found some gas stations in Iowa that had 91 listed as premium and had no octane higher than that. ---- that ----, nothing less than 92 for my cars.

 

lol, sounds like where im from...
