88 to 93 ppm moly? How do I say this w/o starting WWW-III? Not only Mobil but I've seen moly counts even lower in other oils. Then there are oils that contain no mloy. Is there any point to such a small amount?
My question is because I want to understand, not bash the product. I think they use other AW adds instead of moly, so I just don't understand why they'd even bother with such a low count, unless that is all the moly that is needed?
Smaller amounts of soluble moly act as a FM agent. Larger amounts of soluble moly, 300 or more, act as an anti wear agent. This was told to me by a Mobil 1 rep. Also, there is a thread on here, a few months back, that discusses different types of moly and their use. A Mobil 1 engineer came on and spoke of different moly types and amounts. It would be good to search for that thread.
As far as noticing any difference in fuel economy or power with "thicker" HM oils, no worry. I run Mobil 1 15W-50 in two current vehicles that spec 5W-30. Both get better, one much better, than EPA estimates, start before you can release the key, and there is certainly no reduction in power output. I have driven identical vehicles(friends and neighbors that let me drive their vehicles and I let them drive mine to demonstrate this point) and not only no loss in power but I think some of the smaller engines, I4 and V6 actually show more power.
