Run what's recommended, premium.


It's like using 2 cycle bike oil. I mean factory recommends 5w-30 but what the hell it's still oil right? Ha

Can notice a difference and will run regular on a Highway trip.

Have bought a few tanks at Sams Club and am about to reach the conclusion that my 94 LS is Ethanol intolerant. Really makes it run like hell.
