I have a barrel of 15W-40, but have not ran a full oil change interval on it as of yet. Nothing unexpected has happened and it's just another engine oil IMO. The specs met what was needed for my Allis 11-B dozer, so evaluating it there.

ALl oils have an SAE spec.. Autos are Sx and diesels are Cx... where the "X" changes over the years with oil refinements... Allis is old enough that just about ANY Cx oil is acceptable..
Diesel Engines(Follow your vehicle manufacturer’s recommendations on oil performance levels) Category | Status | Service | | CK-4 | Current | API Service Category CK-4 describes oils for use in high-speed four-stroke cycle diesel engines designed to meet 2017 model year on-highway and Tier 4 non-road exhaust emission standards as well as for previous model year diesel engines. These oils are formulated for use in all applications with diesel fuels ranging in sulfur content up to 500 ppm (0.05% by weight). However, the use of these oils with greater than 15 ppm (0.0015% by weight) sulfur fuel may impact exhaust aftertreatment system durability and/or oil drain interval. These oils are especially effective at sustaining emission control system durability where particulate filters and other advanced aftertreatment systems are used. API CK-4 oils are designed to provide enhanced protection against oil oxidation, viscosity loss due to shear, and oil aeration as well as protection against catalyst poisoning, particulate filter blocking, engine wear, piston deposits, degradation of low- and high-temperature properties, and soot-related viscosity increase. API CK-4 oils exceed the performance criteria of API CJ-4, CI-4 with CI-4 PLUS, CI-4, and CH-4 and can effectively lubricate engines calling for those API Service Categories. When using CK-4 oil with higher than 15 ppm sulfur fuel, consult the engine manufacturer for service interval recommendations. | | CJ-4 | Current | For high-speed four-stroke cycle diesel engines designed to meet 2010 model year on-highway and Tier 4 non-road exhaust emission standards as well as for previous model year diesel engines.

Like them all, but love the "B"s.

My concern would be the Zinc content needed for the old flat tappet camshaft. I was just into an engine ruined by the owner using the latest/greatest flavor of the month oil where the lobes were wiped off and the tappets where all but wore off as well.

If it was fun to pull in LOW gear, I could have a John Deere.
Real pullers don't have speed limits.
If you can't make it GO... make it SHINY

Many a classic car owner has had this problem, they will claim the modern oil additives are better then zinc but I call BS.
ALL break in oils are high in zinc for a reason.

I've always used zinc additive in my older cars. Now use Valvoline VR racing oil which has zinc. Bought an older pre-roller cam Pontiac Sunbird this spring. Cam and lifers were worn bad from no zinc.
