I recommend a quality 10W30 all year round, unless your winters are below freezing. Then 5W30 in winter.
 
That would depend on the engine manufacturer and the average winter low temperature. Mostly a 10W 30 or 40 would suffice in temps to -10 below. Below -10 5W 20. Does anyone know what the W stands for. If the temp does not fall below 0 a 20W 50 would be ok according to Kawasaki. The 20W 50 would also help with oil consumption in the hot summer temps.
 
I just look for an oil which has the API & SAE approval stamps. Other than that I say it’s a crap shoot, but many on this forum will not agree with me. If you change it regularly it really doesn’t matter

Automotive oils are no designed to run at the higher operating temps of an air cooled engine. They also do not have zinc which is a lubricant for the wear parts especially the valve train.
 
We use Kawasaki and Kohler I mostly use Kawasaki 10W 40 in other brands. I also use it in my CV20 Kohler. Good oil and use the Manufactures oil filters. Are you guys having trouble getting Kawasaki oil filters. Only one we can get is the 49065-0724.
 
All my equipment and every shop I’ve worked in has used what I recommend. Never had a problem in 50+ years. More important to regularly change the oil and filter, if applicable, than the name on the bottle. To each his own, just saying what has work fine for me. When I started in the sixties that’s all we had and never heard a breakdown due to oil overheating.

I believe that new 0724 has superseded several part numbers, so that may be all you can get. I use WIX 51394 in place of most Kawasaki filters, unless the engine is still in warranty period.
