oil capacity

the engine holds 1.5 quarts , if you have a model with an oil filter add 1 additional pint . you can go to the Kohler web site and download a manual for this engine. as far as oil type I run full synthetic 5w30 , I know some people don't like the idea but I have over 2000 hrs on the engine and it still runs great. Maybe I'm just lucky
