My last oil change I decided to use 10w30 full synthetic oil in my 1650 hour kohler command on my terramite. I've put 80 hrs on the oil change. Oil looks like new, hasn't used a drop. In the past I would use 10w40 non synthetic oil and after 60 hrs it would turn dark. After 75 hours it would be down a little on stick. Between 60 and 75 hrs I would change it.
Kohler says I should change oil every 100 hrs. I'm going to push the full synthetic to 100 hrs and see what it looks like. So if oil still looks good should I change it or let it go a little longer?
BTW, I'm using the same brand of oil, which I'm not turning this into a brand name war. I will just say I've been using the same oil for last 1250 hrs that's how long I've owned it. This is the only time I've used synthetic and in the past I used non synthetic.
I know there are some who say you must run an air cooled engine wide open. I've been running at half to 2/3 full speed as stated in my owner's manual, all the time I've owned it. So it not running at full speeds damages an engine, why haven't I damaged mine? Some say 1650 hrs on a kohler command is on borrowed time. Some at a small engine shop tells me, they have seen kohlers with 6-7000 hrs if taken care of.
Only time will tell. At the rate I logging hrs, about 200/year, it will be interesting how many years this will last. The engine is a 2004. I've owned it 6 years now. Bought it with 400 hrs.
