Can this be do? Should it?

[Newbie_ttk11]

So I’m trying to find one oil for all my equipment/vehicles, this way I can buy bulk and always have it on hand. The equipment/vehicle list is below with the manufacturers recommended oil. With the exception of the KTM and the snowblower I think I might run the Castrol Grand Prix for Motorcycle 10W40. I live in southern BC and see extreme temperatures from -25C to +35C and averages of -15C to +25C. I use the Grizzly 700 for plowing in the winter as well as the snow blower.
I’m not hard on my stuff, no mud bogging for the atvs, just trail. The most aggressive thing I do is plow a 30 foot driveway with light snow (not wet and heavy).

Questions:
1 Is the MA rating bad for small engines?
2 Is the Rotella Triple Protection 15W40 semi synthetic base? I’m asking this based on the oil temperature ranges that I found below.
3 I plan on doing oil changes once a year (maybe twice on the grizzly, it gets used the most), would one of the below oils be better for that?
4 What would you do?

Polaris 850 xp - PS-4 PLUS Performance Synthetic 2W-50:
“Mixing brands or using a non-recommended oil may cause serious engine damage. Always use the recommended oil. Never substitute or mix oil brands.”

Grizzly 700 - Use 10W-30 marked A.P.I service "SG” or higher, JASO standard MA

V-Star - Use SAE 10W-30 API Service SE, SF, SG, type or higher

KTM 690 - Use 10W-60 marked JASO T903 MA

Honda lawnmower GC 160 - Use 10W-30 marked A.P.I service "SJ" or later:
“Using non-detergent oil can shorten engine’s service life, and using 2-stroke oil can damage the engine.”

Karcher pressure washer GC190 (Honda) - Use 10W-30 marked A.P.I service "SJ" or later:
“Use 4-stroke automotive detergent oil.”

Craftsman Snow Blower (Tecumseh) - Use 5W-30 marked API service “SF”, “SE”, “SD”, “SC”

Go for 10w30. Maybe a gallon of MMO in case of a cold snap. I don't think there is a 4 stroke made that won't run on 10w30. The OCI is situational.

What I was thinking.
About as close as it gets to an all-purpose oil.

You gotta watch the 10W-30 Rotella's. They are all CK4 with reduced Ph Zn. The 10W-30 falls under the scrutiny of car lube regulators ...

The 5W-40 Rotella T6 is not at this time. It's not that heavy. I think it's more like a 5W-36 or something. Works well in almost all your stuff. Is on the Allison list approved for heavy equipment with mixed sump use (wet clutches and wet brakes). The 5W will see you through all your winter needs.

It's also rated JASO MA for all your motorcycle and ATV needs

There remains plenty of CJ-4 on clearance at Wally's for $21.00/10 qt jug and there's then the rebate which makes this oil dirt cheap.
T6 is also a dual rated oil so it would be just as subject to scrutiny from the car lube regulators as T5 would be.
Personally, in a dual rated 5W-40, I'd prefer either D1 or Delo over T6, but that's just my opinion.

Thanks guys,
the search on walmart.ca for Shell Rotella is turning up 15w40 no 10w30, and costco.ca's T4 and T5 is 15w40 as well.

A lot of people get worked up about the reduced PH and Zn. Nobody talks about the other anti-wear additives added in its place. Now, I understand some oils may not have done that. So, are those other anti-wear additives ineffective in an OPE?

Id just run the recommended fluids in each.
