I have heard of the moly plugging up filters too (I have never had it happen to me).
I used come clear stuff on a few engines and I really liked it, but I cannot find it anywhere (maybe for good reason). I have plenty of the moly lube in the garage. I just saw a can of white grease sitting there and had a flash back, wondering if anyone still used it.
I guess I will stick to the moly stuff. I didn't even think about the higher melting point, this is both good and bad. If you think about it your oil should never get hot enough to melt it.
As usual great input.
