Okay, background then questions.
I'm a big fan of Pennzoil in my Jeep and will be running that for the foreseeable future. PYB is very high in moly as most here know.
Due to concerns with the piston skirts on my Jeep engine (a known weakness in the model) I have also been using MoS2 off and on in the past, now on again and I plan to stick with it as well. It is my hope the MoS2 may offer a little more protection for the piston skirts. Not sure it will help but I don't see any way it could hurt, and I put so few miles on the Jeep anymore the expense is negligible.
Here's the question though, does anyone know if the MoS2 might actually interfere with the soluble moly in the PYB, inhibiting it from doing it's job? Are these two moly's "competing" with each other?
My understanding is the MoS2 plates under heat, and once plated wants to stay there, which is why I thought it couldn't hurt with the skirts. Once plated I also thought it would be good for short trip protection (which I do a lot of these days). But I also wonder if it prevents the PYB moly from performing as it should.
I plan to stick with the PYB and MoS2 but this has got me thinking and wondering if I should rethink my strategy. Would the MoS2 be better off with a PCMO that has no moly? Would the PYB be better off with no MoS2? Some of the recent UOA's with PYB in the Jeep 4.0 have been amazing. I did one UOA a few years ago with Castrol HM and MoS2 that was not very impressive but there were other things going on OCI also I think.
Thoughts????
