I have a 2011 Cub Cadet GT2000 (purchased new) with a 20HP Kohler Command engine. Has roughly 400 hours of use after 10 seasons with an oil change each season (averaging 40 hrs use). I have used the Kohler brand 10W30 oil (conventional) as recommended by Kohler for the Command Engine without any problems at all. It does not use any oil. Spring is coming up and I will change the oil soon.
1. I have been seeing some blurps on the internet regarding the Kohler brand 10W30 conventional oil as "NO LONGER AVAILABLE" with the exception on current stock on hand at suppliers. The bottles now state Kohler engine oil (Semi-Synthetic 10W30).
2. Have seen a statement by someone that says they contacted Kohler about this and were advised that the old Kohler 10W30 was Semi-Synthetic but was not listed on the label.
3. Some have said just to use the new Semi-Synthetic and don't worry about engines with a lot of hours on them as they would be fine.
I really liked the Kohler engine oil. It had a high ZDDP content, I used it in very hot weather, 95 degree without any burnoff.
I WOULD SINCERELY ANY THOUGHTS TO MY QUESTIONS LISTED BELOW.
THANK YOU
Questions for those that may know or have experience on this matter to reply.
1. Was the old Kohler 10W30 oil (Semi-Synthetic)?
2. If it was not, would the Kohler semi synthetic 10W30 have any negative consequences on that 20 HP Command after 400 hours of conventional oil use?
3. If yes to question 2 (negative consequences) I plan to switch to Shell Rotella 15W40. It does not get that cold where I am and I don't get on the mower for anything if the outside temp is under 50 degrees. Just fall leaf cleanup. What are your thoughts on Shell Rotella 15W40?
