Currently running this oil in the 4kW Predator generator, and the huskavarna riding mower that’s a 25hp Briggs twin.
After reading through this forum I have the impression that the Xw-40 HDEO are the “best” for extended operation in summer temperatures. I’m in the Florida panhandle and summer and hurricane season is upon us.
M1 HM 10w-30 has HTHS of 3.5 and is ACEA A3/B3. It is API SN so only has 800ppm zddp.
I would like your thoughts on replacing this oil with some rotella t4 15w-40. The yard is about 3/4 acre and takes 1-2 hours to mow depending on how thick and wet the grass is. Thicker grass means more mulching passes.
The generator is rarely used but would be run for as long as needed to keep refrigerator and freezers cold in the event of a power outage.
