oliver2-44 9,726 #2 Posted July 15 An oil question will get lots of points of view. I've run Mobil 1 synthetic in my Kohler's for 5+ years now. The only restriction I'm aware of is they suggest using a conventional dino oil for a new/rebuilt engine ring break-in. JMHO 3 Share this post Link to post Share on other sites
Achto 27,562 #3 Posted July 16 Personally, I like Rotella diesel oil. Lower price with more dino juice. 3 Share this post Link to post Share on other sites
8ntruck 6,998 #4 Posted July 16 better extreme pressure additive package that is more suitable for our old school Kohlers and Onans, too. 2 Share this post Link to post Share on other sites
