I'm looking to purchase Royal Purple oil for my 2002 GT. MY question is, should I purchase the royal purple racing oil orroytal purple motor oil? I'm running a 75 shot of nitrous and I race every other weekend. Please help.
normal (full synthetic) royal purple is racing oil for us "novices". Don't use the racing oil unless you trailor your car everywhere and only drive it on a track. Yes racing oil is better for racing but doesn't have as much detergents (if any) to break down the random junk and particles that get in your engine from daily driving.
