Re: Regular or Premium Fuel (chriswtx)
Well logic has to step into play somewhere. A 9:1 compression engine is not going to need premium. You're right, you might not know, but you can usually hear a slight pinging before the computer does retard timing.
Like I say, I run premium on mine with no detonation. I haven't had the chance yet to try and data log it with lower grade fuels to see what's going on so in the mean time I'll play it safe. For a stock car though you're best off running what the manufacturer recommends, which in most cases is NOT premium.
The only way to know for sure in a modified application is to data log. It's pretty well proven though that it does nothing to run premium in a stock TPI.
