Harley Dry sump
Lawn mower Wet sump
Harley Oil pump, actually 2, one scavenge and one pressure.
Lawnmower, splash some are pressure feed
Harley Needle and roller bearings
Lawnmower plain bearings
Harley piston squirt oil for lube and cooling
Lawnmower, splash
Harley separate oil cooler passive air flow
Mower, forces air cooling, no separate oil cooler.

I can go on but I think it is a little mind blowing to claim they have much similarity

10~4 on that (sorry) …
I’m thinking M1 10w40 HM would be awesome … but I have some extra Delvac dino on deck first

We got in the low 20’s just one time last winter … but tell my poor palm trees (those left) that’s nothing …

You forgot the following:

Lawnmower - very reliable with little to no maintenance and running on any swill resembling oil....

I use whatever 10w30, or 10w40 is on sale in the Diesel section of oils at walmart.

Once a year intervals for my Briggs powered Deere.

While I cannot speak for the rest of you, what that chart says to me between the lines is that I should run synthetic 5w40 in all of my OPE. Commercial operators don't have a choice, but I myself won't be mowing at 90 degrees F, let alone 120. At the opposite end of the temperature spectrum, my snow blower starts in the garage at or above freezing, and our local extreme low of zero or a few degrees below isn't going to matter once that machine is warmed up. The charts suggest to me that I can easily run synthetic 5w40 from 0-100 degrees F. Anyone seeing that differently?

Presently my OPE fleet is running 5w30, 5w40, and 15w40 oils. Running 5w40 in all of them seems the obvious compromise.
