Hey guys, I wanted to get some opinions on this. I just picked up a 2002 GT, 4v swap, with a Vortech V2 supercharger. The previous owner ran 5w30 Royal Purple HPS in the car. I personally haven't ever been that big of a fan of anything but Mobil 1. On the next oil change, I want to switch over to the Mobil 1 full synthetic, run it for about 1000-1500 miles and short change it to get the rest of the residual RP/zinc additive out, and fill it back up with more Mobil. Anyone have any input on this? I just wanted some reassurance.
