didnt you have some engine dyno tests looking at the oil filling up in the heads?
I seemed to remember someone putting a plate on the valve cover and filming oil characteristics.

I can put Mobil 1 into freshly rebuilt tranmission and it will not leak past the seals. Anything else you want to put into one of my rebuilt transmssions is OK with me....just don't call me when it leaks.
Redline leaks 100% of the time, as do other synthetics. Draining this stuff out and putting in Mobil 1 generally will stop the leakage after a few miles....so the seal isn't actually damaged.....it just can't seem to properly seal.
New seals have a very "sharp" edge (almost like a "V", in cross section.) It seems like once this "V" gets flattened down some (wear), you can then use some of these other synthetics. Perhaps the sharp "V" of a new seal is too sharp and the "better" synthetics are so slick that the new seal can't get a "bite" on the shaft....
I don't really know why....I just know what leaks and what doesn't leak.
