Millers Oils Competition Assembly Lube (1 litre) has been specifically formulated to give mechanical protection during initial start-up of newly assembled components. Assembly Lube has a high concentration of antiwear additives for initial assembly of engines and transmissions, especially components which are subjected to high stress levels (i.e. camshafts/followers, crankshaft bearings etc.). Unlike Assembly Paste-type compounds, Competition Assembly Lube is fully miscible and compatible with all engine oils and will fully dissipate on start up, reducing the need for an extra oil change.
