WOW 25K between oil changes, I didn't realize Mobil 1 synthetic had been around that long. The Crossfire is the only vehicle I've ever ran Mobil 1 synthetic in, I have always used Valvoline in my vehicles and the engines that I have tore down in the past, (mine & friends) never used Mobil 1. I figured there were some differences in oil, but didn't know there was that much difference. Sorry to get peoples panties in a wad over this topsider device that was originally designed to get oil out of a vehicle that was overfilled.
