slammer302 2,156 #2 Posted June 2, 2014 Kohler recommends a high quality 30wt oil for summer and 10w 30 for winter I have several k181 Kohler's always had good luck with 30wt oil and sum Lucas heavy duty oil stabilizer Share this post Link to post Share on other sites
Kelly 1,033 #3 Posted June 2, 2014 Straight 30w oil, of your brand, but finding it in any brand is getting harder, when I find it I stock up a case or two, but most people don't own as many tractors as I do. Share this post Link to post Share on other sites
