I use the valvoline 15w-40 in my truck. The thing I have noticed most is the oil pressure usually is around the middle of the guage at idle, but with this oil, it's slightly off to the right of center, just a bit. Another thing is less blow-by in the aircleaner. That diesel has been smokey since day one, and running valvoline, it doesn't seem to burn as much. It's still a diesel... any engine with 22.5:1 compression is gonna have lots of blow-by.
For the bikes, I have always used redline. it's expensive to put in a car(deffinitely wouldn't put it in the truck, which holds 16 quarts/4gals.), but I can justify the cost easier when I only have to buy 1 or 2 quarts.
