I'm trying to find a cheap, yet good diesel oil for a Goodman Ball (now made by Dewey Electronics) MEP-952B, 5kW 28VDC Diesel Engine Driven Auxiliary Power Unit (APU) found on US Army tracked vehicles.
Figured these would be a good candidates:

https://www.walmart.com/ip/Mobil-Delvac-15W-40-Heavy-Duty-Diesel-Oil-1-gal./17034368
The manual says this about oil requirements: MIL-L-2104, 15W-40 (0 to +120°F) aka OE/HDO-15/40. I know there are different MIL-L-2104 revisions, with MIL-L-2104K being the latest and pretty sure this APU was designed for earlier revisions (if any). Not sure what that translates to in API certification. MIL-L-2104E was API CD, but saw on Shell's T1 single viscosity oil that it was API CF. It calls for 300 hour service intervals and indeed burns/leaks oil. Thinking, instead of using junk oil the Army uses, replace with a "full synthetic" oil to get a longer service interval. 300 hours is only 12.5 days running 24 hours per day. Would like to be able to run for 720 hours straight with less oil consumption and better efficiency. If it only takes a gallon of oil, maybe I should get an Amsoil SS four-cycle small engine or diesel oil?
Some background on MIL-L-2104:

definition of high-temperature use limits for mil-l-2104 engine oils
It has a 290 cubic inch, four cycle, single cylinder, air cooled, fuel injected, horizontal cylinder 15 HP @ 3000 rpm and 27.4 ft-lbs @ 2000 rpm diesel engine. Compression is 19:1.
Oil consumption at 5.0 kW 0.04 ounces (1.0 gram) per kW hour.
It's alternator is a brushless, six phase, negative ground, externally energized, and self-rectifying. It's supplied with an external, solid state regulator with flat temperature
compensation, a twin fan assembly, and fan guard.
Output at 1000 feet elevation and 107°F is 5.5 kilowatts, 180 amps, 28 VDC at 3000 rpm.
Can you believe new this thing is $40k?
