thread here but why should it not get 15w-40? Looking at my first oil change and finding info about these trucks is like sifting through sewage….everyone has an opinion and they all think there’s doesn’t stink.

Read your owners manual yet?

You leave yourself wide open on this forum with a when should I and what do you use question . You will just have to make the final decision based on what you read . As others have said and your manual states use synthetic oil . Believe me the engine manufactures are conservative on their change intervals . They have a vested interest in your engine lasting as long as possible . This ain't your Daddy oil ! You read the back of any of the mentioned oils and they will essentially say the same thing . Meets or exceeds manufactures specifications . The brand is your choice .

There should be no opinions on this, it's spelled out in the manual. For a 22 it is 10-30 or 5-40 depending on the temps at your location.

In 2019 Cummins switched to a hydraulic lifter which requires a thinner oil.

The only grade that requires synthetic is 5w-40. 10w-30 does not have to be synthetic.

It's really a mute point thou as every 5w-40 is synthetic, and most 10w-30's are a sythetic blend.

For explicitness, CTRL+C, CTRL+V 2022 manual.

“Change engine oil every 15,000 miles (24,000 km) or 12 months or 500 Hours or sooner if prompted by the oil change indicator system, whichever comes first.”

Products meeting Cummins® CES 20081 may also be used. The identification of these engine oils is typically located on the back of the oil container.

It is written on the oil fill cap as to what you should use.

Guys, calm down. Yes, I’ve read the owners manual, come on.

What I was looking for was a technical description, not a redirection to the manual.

Thank you to the guy who posted the service bulletin, that was exactly the explanation I wanted.

Wasn’t looking to start arguments.

I was kind of chuckling. Everyone seems to want to discuss oil on every car, truck, tractor, or boat forum I've ever been on. Then when someone discusses oil or asks a question there's a "not this again, why are you asking" response from somewhere.

It was more the way you asked.

I have yet to see any BS or opinion on why you can't run 15w-40 in the 19+ trucks, on any forum. It's a cut and dried issue and a little research will show you why. But at the end of the day it doesn't really matter, since it's not a grade of oil listed for use in the owners manual or on the cap.

Based on the vast possibilities of oil brand war threads there were zero arguments started here.
