I read in another post guys didn't like certain oils, one of which i run. So what oil works best with alky, making 880 hp, 528 cubes, 15/1 compression?
Yellow rose, as a last (15th) dyno pull on my 528, i dumped the reg oil and tried Mobile one, same vicosity. I lost 15 ft lbs of torque, and didn't have a clue why. I thought i should test it at the track too, car slowed down. Is Mobil one a class4 or 5 ayn?
As i recall, (2003!) It was regular 20w50 m1.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.That's a good question and I don't know.

Would it be correct to think that 5 degrees of temp change or 20% humidity change could make a .05 difference? It just seems hard to attribute to the oil alone, unless all the parameters were tightly controlled.
Mobil 1 is a pretty thin oil across all temps, and unless the oil temp was over 200 degrees, it would actually still be thinner viscosity than a standard dino oil of the same hot temp weight. Might be being pushed/blown off of the rings easier.
I have a friend who runs a 800 plus small block w/ alky. He runs BRAD PENN I know several guys who run that in there race engines & street enginesI read in another post guys didn't like certain oils, one of which i run. So what oil works best with alky, making 880 hp, 528 cubes, 15/1 compression?
Boring, no! Being able to get a car to run within .004 ,four psses in a row, makes me happy. It also messes with some of the competition.Gotcha...tnx. That level of consistency must become boring... LOL
I'll bet it does.. nice work!It also messes with some of the competition.
