Just go down to Wally Mart, buy 5W40 synthetic if you want synthetic, or ANY of the conventional 15W40 oils if you want conventional, or SAE40 oil if you want to run a single weight conventional, and call it a day.
5W40/SAE40/15W40 is what you want for commercial use, in Florida, in a Kawasaki. If you have an Kohler or Briggs engines, these oils will work fine in them as well. Kohler Command engines get heavy duty 10W30 oil ONLY.
I have done thousands of oil changes on commercial power equipment in Florida and am pretty in tune with what works down here.
Is there a reason that you can't use any of those 40 oils in a Kohler Command, other than the manual saying only 30? Couldn't you use the heavy duty 10w30 in the Kawasaki?

I understand SAE30 might not be available locally so my suggestion is to get an oil with suitable viscosity, from what IS available.
All of them recommends 10w30 as much as they recommend SAE30. B&S is even recommending 5w30 synthetic at all temperatures. Without no hard facts, we can only assume.
If it's recommended, I'm not arguing...

Sometime I may appear to be arguing, but I asking questions to see how people come to there conclusions and see what I can learn from it. Maybe in the old days did OPE's only recommend SAE30, but go buy a new one today and most are least 10w30 and SAE30. So if HTHS of 3.5 or more was important, than why is 10w30 is acceptable and even recommended? Now granted, some give a warning to watch for increase consumption.
As some say on here, just make sure it at least have oil, as all that really matter. What it really has doesn't matter.
