MOTUL CLASSIC NINETIES 10W-30 meets manufacturers' standards from the past, while benefiting from today's advanced MOTUL lubricants technology. It is formulated with a unique combination of High Zinc, Phosphorus (ZDDP content >1800 ppm) and Molybdenum additives to provide the best protection and performance in naturally aspirated, supercharged, and turbocharged engines found in American, Asian (including boxer and rotary engines) or European vehicles from the 1990's. High ZDDP levels offer supreme protection of critical components like high-lift, flat-tappet cams, prone to wear because of the high friction developed in these parts. Molybdenum has a synergistic effect with ZDDP, lowering friction while increasing the lubricating film's strength, engine efficiency and power.
