About Oust Met-Ol:
Oust Speed Oil is a proprietary lubricant manufactured from straight chain carbon molecules with at least 6 carbon atoms being used as a boundary layer lubricant. Under high temperatures created from frictional drag, these molecules form a metallic soap which become a tenacious lubricant film of increased viscosity to reduce the wear in the boundary region. All OUST Bearings come lubricated from the factory with MET-OL Synthetic speed oil. All MOC Series bearings should be lubricated every 6 hours of use with MET-OL Synthetic speed oil. When skating slalom, down hill racing or distance racing the bearings should be lubed every 2 hours of racing. (Courtesy Oust web site)
