Pro-Line Oil Loss Stop rejuvenates rubber and plastic seals in the engine and reduces oil consumption via piston rings and valve guides. It counteracts the loss in viscosity of motor oils and puts an end to environmentally problematic oil patches on the road and in the garage. Compatible with all commercial motor oils.
Oil Loss Stop regenerates rubber and plastic engine seals (e.g., shaft seals and valve stem seals). Reduces oil consumption through piston rings (due to its uniform viscosity) and through valve guides (by regenerating the seals). Prevents blue exhaust smoke. Compensates for viscosity reduction and dampens engine noise.
