Only noting that Mobil 1 0W-40 has Mercedes-Benz 229.3 approval and is suitable for diesel engines without a DPF. API CF is obsolete and that's why ExxonMobil lists it as a recommendation and not a license. I wouldn't use the oil based on the obsolete API category, but perhaps that's just me.
Kubota only recommends 10w30 or 15w40

API CF superceded CD in 1994. The oldest still in existence is CH. CG and older including CF2 are obsolete classifications.

yeah, i have used napa 5w40 sonce new, probably wont stop. having 2 oil aint that bad.
mb229 seems like a high standard. i might start using in in my new to me lx570.
Kubota Camp: " I WILL use 5W-40!"
Ram CTD Camp: "I WON'T buy a truck that doesn't recommend 15W-40!"

FWIW, a guy here has a Kubota powered generator for his wife’s dog grooming business. I thought the same thing as you, but he had done many UOA’s that proved the oil was just fine for his application.
An A3/ B4 oil by definition is a gas and light duty diesel oil. I’m not exactly sure what the line between a heavy duty and light duty diesel is though.
I have stared at the insides of a d722 and the service manual longer than I want to admit, it’s a pretty basic and extremely stout engine. I don’t think I would risk light duty diesel oil in something more complicated beyond its larger cousins (d902 etc) but still fascinating it has worked so well.
I wonder why they list CF then? What can one use CF in?
All it tells you is that it’s dual rated gasoline and diesel. Long obsolete it’s hard to find information and test procedures for CF, but it might align with Cat 1MPC oil spec.
A better way is to look for an ACEA approval such as A3/B4 which is a current specification.
A look on the back of gtx 20w50 shows api sp and acea a3b4. Not sure about the 10w40, I’ll have to go look. The 10w30 is api sp/sn+, so it’s not dual rated.

Looking at my manual for the truck, which is a military TM (good and bad I suppose)....
It states and oil with BOTH SF and CC or CD requirements. I have never seen this. I see no reason why one could not use a typical current diesel oil in it. Interesting though. There are many out there that list SN an CK, just wondering if 0w40 M1 would work. I suppose it would be a "light duty" oil for diesels. This thing runs at full tilt at 55 mph, and perhaps it would be dumb to try it.
Me Too !!!!
Use the Euro FS 0w40 for dual rated gasoline and Diesel.
Look for A3/B4 on the container.
Trying out a 5w50 A3/B4 in a 6.6L Duramax is on my bucket list.
Definitely not true. I also service the folks that repair combines and such - Deere parts availability, are much more significant over New Holland, Kubota, Case, etc. Yes Deere parts can be expensive, but being able to get the part same day or next day is a huge contributing factor.
To those that actually work on them day in and day out: I never hear a mechanic say they'd rather be working on orange, blue or red.
I run 5w40 in both Kubota and Cummins year around for years now -40 degrees to 108 degrees I am thinking about 0w40 in the future
