I know how MoS2 is supposed to work. And I believe it does what they say it does because I've actually used it. But, curious, does anyone know if MoS2 will bond to aluminum piston skirts and/or the cylinder walls? I understand it is supposed to plate metal bearings and such but I wondered if aluminum pistons were different.
My model Jeep has been plagued with piston skirt issues in the past and I was curious if MoS2 would slick 'em up. I've used in it the Jeep before and did get a slight mileage boost and quieter running, however my one UOA with it in the crank showed fairly high aluminum. One done later without it did not. However the oil in the UOA turned out to be a 5w20 (long story) and old Jeep 4.0 pistons do NOT like 5w20's. The later UOA was a 10w40 so I imagine that's why the aluminum came down so much.
Just curious, thanks!
P.S. I am not asking whether or not I should use it, whether or not you like additives all that other blather please save just curious about the aluminum and MoS2 or any pertinent discussion to that please.
