Lucky for me the high pressure PS line failed right where it's sitting...nice mess under left front. Order new hose (great vendor network..much like 928s), tilt cab with crane (covered by brown tarp), support with 2x4s on both rear corners, easy access to line over left front tire, then add...Rotella T motor oil! Yup, Mog PS uses same oil that does in the engine. Mog Life is simple, by design.
