Re: rotella 5w-40 in gas engines
Kingtut, I can tell you from personal experience that different brands of oil can make a huge difference. PSD's are the most sensitive because of their HEUI system that uses the oil as hydraulic fluid, but IDI's can also be affected (primarily useage levels).
I had a wrecker that would literally run out of oil with Brand X, and use a quart a week on Brand Y.
Oil these days IS complex, all the additives are one reason we are no longer scrapping cars at 90K for worn out motors.
