Wonder if the zink content is that much higher than M1?

I think the ZDDDP is about the same but it has a heavier handed dose of friction modifiers..ie moly.

Hydro, are you still high on V-Twin?? I drained the Brad Penn and I'm about to reorder......1200hp, 1471's.

Why do they make things so confusing? What was wrong with the old product line? Blah...

I guess I'll have to decide between the straight synthetic 20w50 or the dominator 15w50. The first number is the low temp viscosity, right?

I've used it in my Duramax with a dual remote filter and consumption was low which is a good thing!
Presently have Delo400 in my Powerstroke and no complaints either.
For the performance boat engines I would want a higher viscosity number such as 15w50 - 20w50

Oh, yea..20W-50 M-1 V-Twin 1600 ppm Zn and Ph. If you can spring for it a remarkable product.

Just one of those things. I'm going to be switching to the new 15w-50 as soon as my 20w-50 Series 2000 is used up.
