Oil Recommendations
All-season KOHLER® PRO 10W-50 Synthetic Oil is the ideal oil for KOHLER engines. It is specifically
formulated to extend the oil change interval to 300 Hours. Contact your Kohler authorized dealer for
availability. 300-Hour oil change intervals are exclusive to and only authorized on KOHLER engines
that utilize the KOHLER PRO 10W-50 Synthetic Oil. Alternative engine oils may be used with
KOHLER engines but require 100-Hour oil change intervals for proper maintenance. Oil must be API
(American Petroleum Institute) service class SJ or higher. Select viscosity based on air temperature
at time of operation as shown below
Check Oil Level

operating range indicator on dipstick.
Ensure engine is cool and level. Clean oil fill/ dipstick areas of any debris. 1. Remove dipstick; wipe
oil off. 2. Reinsert dipstick into tube; rest on oil fill neck; turn counterclockwise until cap drops down
to lowest point of thread leads; do not thread cap onto tube. a. Remove dipstick; check oil level. For
CH260/CH270 engines, oil level should be at middle of indicator on dipstick. For all other models, oil
level should be at top of indicator on dipstick. or b. Remove oil fill plug. For CH260/CH270 engines,
oil level should be to middle of filler neck threads. For all other models, oil level should be up to point
of overflowing filler neck. 3. If oil is low, add oil to specified level on dipstick or filler neck threads for
engine being serviced. See step 2. 4. Reinstall dipstick or oil fill plug and tighten securely.
Change Oil

drain plug and oil fill cap/dipstick. Drain oil completely. 3. Reinstall drain plug. Torque to 13 ft. lb. (17.6
N·m). 4. Fill crankcase with new oil to specified level on dipstick or filler neck threads for engine being
serviced. See Check Oil Level. 5. Reinstall oil fill cap/dipstick and tighten securely. 6. Dispose of used
