And voila:

Hahahaha.
I thought maybe AC Delco or Delco-Remy had started branding their own oil label.Account deleted.
Any brand of 15w/40 oil with any of the following API classifications will be fine to use. The actual brand name is of minor significance. Look for the API Doughnut on the label. Your Valvoline oil should be fine, but check the label.
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. 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 drain interval. API CJ-4 oils exceed the performance criteria of API CI-4 with CI-4 PLUS, CI-4, CH-4, CG-4 and CF-4 and can effectively lubricate engines calling for those API Service Categories. When using CJ-4 oil with higher than 15 ppm sulfur fuel, consult the engine manufacturer for service interval.CI-4 (Current)
Introduced in 2002. For high-speed, four-stroke engines designed to meet 2004 exhaust emission standards implemented in 2002. CI-4 oils are formulated to sustain engine durability where exhaust gas recirculation (EGR) is used and are intended for use with diesel fuels ranging in sulfur content up to 0.5% weight. Can be used in place of CD, CE, CF-4, CG-4, and CH-4 oils. Some CI-4 oils may also qualify for the CI-4 PLUS designation.CH-4 (Current)
Introduced in 1998. For high-speed, four-stroke engines designed to meet 1998 exhaust emission standards. CH-4 oils are specifically compounded for use with diesel fuels ranging in sulfur content up to 0.5% weight. Can be used in place of CD, CE, CF-4, and CG-4 oils.Account deleted.
Ok, didn’t know you had a two cylinder engine. That changes things. You likely have an early 1963 model M444 which came with a 15.5 HP two cylinder Onan engine, or a later ’63 model M500 or M540 which came with a 24 HP two cylinder air cooled Kohler engine. The Four cylinder 24 HP Wisconsin engines didn’t appear until ’67 in the model M600.

David, I told you what model you had, but now I forgot what it was. :scratch: I think it’s in another one of your posts.

bob did you figure anything on the ford truck problem?
Yes I did. What I thought was going to be a $25k engine replacement turned out to be a $20 alternator rear bearing. What I determined is that when alternators are mounted rigidly to the engine instead of on brackets, any alternator sounds will be manifested as engine sounds, and at a much greater magnitude. I had hand-spun the alternator and it seemed fine while I was replacing the coolant pump, both belt tensioners and idlers, and both serpentine belts.
So on another note, I was going to replace all my turn signal light bulbs with LED’s because the regular 3157 bulbs burn up the plastic sockets. Ok, so I purchase an electronic flasher that’s supposed to fit a ’99 to ’11 Ford Super Duty. HA! I tear the underside of the dash apart only to discover that ’08 to ’11 trucks don’t use flashers at all, they have what is called a Smart Junction Box (SJB). The hyper flashing or “bulb out” indicator can be turned off with a laptop computer connected to the CAN-bus at a dealer………….. for a fee <sigh>.

I can’t edit the previous post. The pics didn’t load right as you can see, so here’s the rest.
Well, it seems I can’t add pics in a reply to my own post. Hal must be one paranoid person.
I guess it’s a sign of old age when you become intolerant of things that don’t function as they should.
I already quit TBN. But that was a different story.

LOL. They are trying to tell you something.
