i run Rotella T 15W40, non synthetic, and i love it. i was first suggested this by a highly reputable engine builder, who builds NASCAR and SK modified engines. he suggested using this instead of break in oil, and how the zinc would be very beneficial (two years later FP comes out with that bulletin about zinc content in the oil, relating to turbocharger life) the Rotella T takes awhile to break down even on hot summer days, 5W30 seemed to turn to water in no time flat no matter what season. its also cheap as hell in my area ($60 for 5 gallons) or buy anything else loaded with zinc. just don't waste your money on Mobil 1, its just overpriced junk. if you had the money to spend every couple thousand, Brad Penn makes awesome oil, with very high zinc content. i cant buy this locally, and i haven't put much research into this, but i think the price is still significantly higher than the Rotella.
Redline Heavyweight for the rear end, and transfer case. MT90 for the transmission itself.
