MOTUL CLASSIC PERFORMANCE 20W-50 is formulated with a unique combination of high-Zinc (ZDDP content above 1800 ppm) and Molybdenum (Moly) additives to provide the best performance for larger displacement engines, while still offering protection of critical engine components like high-lift cams and flat-tappets. 
Medium detergent level compatible with elastomer gaskets. Offers excellent oil consumption control, good shear stability and better cold engine start-ups to prevent engine wear after long periods of storage. Multigrade engine oil suitable for year-round use (all seasons protection).
CLASSIC PERFORMANCE 20W-50 meets manufacturers’ standards from that time while benefiting of the advanced technology of today’s MOTUL lubricants.
The high viscosity grade at high temperature (SAE 50) is totally adapted to high mileage engines which tend to be heavy on oil consumption.
Caution: This oil is rated API SF. It is not suitable for use in most gasoline-powered automotive engines built after 1988. Use in modern engines may not provide adequate protection against build-up of engine sludge, oxidation, or wear.
Leaves an oil film protection on engine moving parts during wintering periods.

Drain intervals: drain at least once a year and tune to your own use.
Can be mixed with synthetic or mineral oils.
