My 22 Kohler Command which is supposed to be the same block as the 25 hp and it takes 2 quarts with the filter. Been doing this for 3,252 hours with no internal engine problems.

If I fill it over the full mark, the oil gets bubbles in it like the crank is hitting the oil and then the hydraulic lifters clatter. I keep it at full or less and I have no problems. It also makes a difference if you have the cap screwed in or not too when you check it, how full you get this engine.

My guess is, it will bring it up to the full mark with out it screwed in when putting 2 quarts in it without a filter.
