ANY OIL GURUS OUT THER GOT OPINIONS ON TORCO SYNTHETIC 5W-40 MPZ(MOLY PHOSPHORUS ZINC) ENGINE OIL? THANKS, MIKEYOILNUTT.
They are fools if this is what they are really doing! Why bother designing an oil to go super long intervals at the expense of it not reducing engine wear! I'd rather have an oil that lasts 10k but gets low wear numbers, than an oil that lasts 20k but gets higher wear numbers. I've said it many times before, but Amsoil needs to wake up and get out of their silly 25k/35k claims. There is just way too small of a percentage of people who can go this far of a distance.quote:

The zinc moly relationship is interesting and makes sense why Amsoil told me they don't use it. They said it is not compatible with there long drain formulation. So they could be sacrificing wear for longevity....
