Unlike standard automotive motor oil, KOHLER oil is specially formulated for small engines. Heavy-duty additives offer protection against oxidation, viscosity breakdown and acid contamination from combustion by-products, wear and friction.
10W-30 (Command Oil) is recommended for Command, Courage, Command PRO, Command PRO CS, Triad OHC, and Aegis engines for temperatures above freezing (32°F, 0°C). SAE-30 is an acceptable substitute if temperatures are above 50°F, 10°C. K-Series and Magnum engines should use SAE 30 (Magnum Oil) above freezing. 5W-20 or 5W-30 can be used in all engines when temperatures are below freezing.
For more complete oil specifications refer to your owner's manual. For optimum performance, Kohler's special blend oils are available from your KOHLER dealer.
