How often should I change the oil in a Kohler KT715?

Change the oil in the Kohler KT715 every 100 hours of run time. Because it is measured in engine hours, log the hour-meter reading rather than a date.

What is the maintenance schedule for a Kohler KT715?

The Kohler KT715 is serviced on engine hours, not miles. Key intervals include Air Filter (every 25 hours), Engine Oil & Filter (every 100 hours), Fuel Filter (every 100 hours). Track the hour meter and service each item when its interval comes due.

Does the Kohler KT715 track maintenance by hours or miles?

By hours. Small engines and heavy equipment log run time on an hour meter, so their service intervals are hours-based. ServiceSage Auto tracks the Kohler KT715 by hours and reminds you when each service is due.

Kohler KT715 maintenance schedule by engine hours

Interval	Service	Details

With a precleaner fitted: LPAC element every 50 hours, high-performance element every 75 hours, PRO performance element every 100 hours. Service more often under severe, dusty or dirty conditions.
Every 100 hours	Engine Oil & Filter	Every 100 hours. Kohler authorizes a 300 hour interval ONLY when using both KOHLER PRO 10W-50 Synthetic Oil and a KOHLER PRO Extended Life Oil Filter; with any other oil or filter the interval is 100 hours.

Every 100 hours	Cooling System	Every 100 hours: remove the cooling shrouds and clean the cooling areas. Do this more often under severe, dusty or dirty conditions - a blocked cooling fin area is the usual cause of an air-cooled engine running hot.

Storage Preparation: Out of service 2 months or more: add Kohler PRO Series fuel treatment and run the engine 2-3 minutes to get stabilized fuel through the fuel system, change the oil while the engine is still warm (not required if using KOHLER PRO 10W-50 full synthetic), pour about 1 oz of engine oil into each cylinder through the spark plug hole and crank slowly to distribute it, disconnect the negative battery cable, and store in a clean dry place. Do not use gasoline older than 30 days; E15, E20 and E85 are not approved.
