I have been lurking around here for a long time and can't seem to figure out what to run. I have a 2008 Fusion 4cyl that I have been running PP 5/30 and a Wix filter. Same combo for the first change in a 2014 Kia Sorento. Now I am running VR1 20/50 and a wix filter in my 2001 Trans Am with a built iron block out of an Escalade, forged pistons and rods running a turbo. thinking about going to T6 or M1 0/40.
