The Kohler manual calls for "SG, SH, SJ or higher" 10w30
The oil I was using is a Walmart synthetic 10w30 with API service SP. But......it sounds like some people on the lawn equipment site do not think that this type of oil is ok. I get plenty of people saying I need something else with more zinc in it. Some people even use zinc additives. I also have a diesel truck and some people say to use Rotella. Can someone help clear this up for me? Thanks.
