HELL NO MAN NOTHING BUT THE SUPER + FOR MY BABY! MOBIL SUPER+ 92. Show some love for your motor would you rather eat dry *** round steak or filet mignon. Or if you had to run a race would you drink beer or gatorade.

93 only for me. Don't much care what it costs. And speaking of cost, I just filled up for the first time in my life with a tank of gas that cost me over $2 a gallon.

like everyone said so far...

you have a decently high compression ratio from the factory. because of this if you run anything lower the 91 octane fuel , at wide open throttle you will get ping and knock causeing you cars computer to pull timeing in order to keep your motor from detonating, this in turns KILL power...

i saw a stock 02 ws6 put dow 280 hp on a dyno jet cause it was running 89 octane.
stock mine put doe 325 on the same dyno...with 94 octane

you do the math... it aint worth it using the cheap stuff...

hes exactly right anything lower is not good for these engines mainly because of the higher compression of the engine. If you do many more mods and run cheap gas you could risk seriously hurting your engine more so if you run it hard.
