Best oil for alky? Wear? Hp?

That's a good question and I don't know. I'll look around and see if I can find out. I know that when Torco decided to develop synthetics they bought a bunch of technology from Mobil and Stauffer chemical to reduce the learning curve.

I'd suspect you got a group IV base and you gave up some ring seal. Did the oil look funny when you drained it out? I've seen the Viscosity Index Improvers come out like plastic.

Which Mobil oil was it exactly?

I suspect you hit, or hit hit close, to the reason, YR. All you say about additives and group IV's rings true with everything I had read.

Now whether Mobil 1 is a group III or IV or a blend.... that is still a controversial topic. Mobil does not make it clear. I have not read the court proceedings to see if there are any clues in that about the Mobil 1 base stock; probably never will have the time to waste on that LOL.

Greg's results are pretty interesting. Greg, did you change to another oil and have the speed/torque losses reversed? Or is that still in the future?
