Edy, no one owes me anything, but I didn't start this thread... I believe the hypothesis proposed at the beginning of this thread is unprovable and no one will be able to point out otherwise...
hence my opinion is that paying top dollar for custom lubes is a waste of money for most people.
I don't know where your race track comparison comes from,or the BMW thing,but this thread wasn't about race cars or BMW's, it was about a color comparison of one engine's internal parts versus a color comparison of another engines internal parts that used a custom lube..
