The 7.3's are funny about the oil you use with there unique oil pressure/injection system, that's for sure, I use Rotella in my stuff and get along okay with it, a bunch of little car/truck engines and a N-14 Cummings,, they all have a bunch of miles on them, the N-14 has 750,000, a few of the little engines have 200,000 on them,,so almost anything can happen to them at this point,, they are on the "other" side of good. I think there are 4-5 basically good oil products out there, at a littler higher quality than others and then there are some cheaper variety's that's for sure. I have heard different stories about how some are different, some from different styles of re-fining, some from different sources of origin, one story claimed that oil east of the Mississippi is better for engines because of the paraffin base, some say that because of the high temperatures of re-fining fuels the oil from that process is not as good,, I by "no" means fully understand all of these variables..and I will never fall out with any one by their choice ether,, I'm also fond of well built Blondes and Budweiser beer ;^)

After a few paragraphs I usually close the book and go back to banging out dents.
