every time an oil conversation starts the amzoil people come out of the woodwork. its my opinion they are all dealers. i had amzoil try and sponser one of my race cars some years back, when asked if they would replace an engine if it crapped out over their oil they crawfished on me.
as far as diesels go, i ran delo 400 in a dodge for 300,000 miles with zero oil related problems, have 100,000 on my present cummins with zero problems, and i run shell rotella2 synthetic in my motorcycle with zero problems.
my opinion will always be the same. if you change your own oil, and do it every 3,000 miles, any quality oil will do well, it isn't in the engine long enough to do any damage, go for quality filters, that is even more important, my crew chief got me to using k&n oil filters a long time ago, and i use their air and oil filters in everything including my bike. if you are lazy and let your oil go 8, 10, or 12,000 miles, you need the very finest most expensive synthetic you can find, and will probably still trash a motor.
clean oil is as cheap an insurance policy as you can get.
