    Getting a 20HP Kolher engine and wondering which oil to run. Do you run straight 30 or a multi-grade or do you run syntehic oils? I appreciate all comments. Thanks, Mowman

    I run mobil one 15w 40 weight in my kohler and kawasaki engines. My engine runs so smooth and queit and it will probably not have any problems for a long time. I run synthetic oil after the first 200 hours and before that i just use regular 30 weight. Mobil one is the best stuff. Also if you want to buy some prolong and put a little in, there will be a big improvement in smootheness asnd maybe higherr rpms too. Some dont like additives but this stuff works the best ive tried them all.

    The Command engines have hydraulic lifters and it is recommended not to run straight 30 weight oil in them. You need to use a mulitgrade oil, like 10W30 or 15W40 in them. <p>----------<br>&lt;a href=&quot;http://elmlawnsite.com/&quot;&gt;Eric@ELM&lt;/a&gt;<br>

    Mowman, I had a lifter rapping problem in my<br>Kohier 22hp. The Kohler rep said to run their<br>Kohler 10w-30 oil in the motor and it would<br>solve the problem! We changed the oil and<br>took it out and really worked it. Kohler was<br>right no more rapping.Kohler said it has special additives to keep it cooler. Hope this helps.<br>good luck!
