Maintenance free CCV filter for 2021 Cummins?

[ShinerBock]

We are already getting word that the L9 and B6.7 will have a maintenance free crank case breather/filter for 2021 along with several other updates. If this carries over to the Ram trucks(which it likely will), then no more CCV filter replacement ever 67k miles. The ECM will also be updated to CM2450 and will have increased computing capabilities which likely means more fuel maps for greater efficiency in more scenarios.

For those that do not know, 2021 is the start of phase two of the EPA's crack down on emissions in diesel trucks. Phase one for the past few decades has been centered around the emissions of these vehicles and phase two is increased fuel economy standards which these trucks have been exempt from until now. This is one of the main reasons why diesel manufacturers are adding things like 10 speed transmissions, higher pressure injection pumps, tighter clearances, and thinner oil. They all increase fuel economy/efficiency and they will need it now that EPA fuel economy window sticker estimates will be required just like the vehicles under 8,500 GVWR.

About time. Good!

Unfortunately that will also come with higher prices and the possibility of lower reliability.

That will be a nice improvement. Currently I can get 20-21MPG HWY driving my RAM solo. Not too bad for a truck that weighs 2.5 tons.

Improved efficiency will be great but let's hope we get reliability too. Don't want to repeat previous reliability issues of the last 15-20 years as new tech has been introduced in the trucks.

Factor in a regen and that 20-21mpg drops to a realistic 17-18mpg

17.8 hand calculated when I filled up today and had a regen on this tank of diesel. With cold winter weather and winter tires I can see it go up to nearly 20 once warmer weather and summer tires are on the truck.

No, I was just adding that part just in case why people didn't know why Cummins was making some of these changes. Not all of the changes are for fuel economy.

My 15 is looking better all the time.

About time. Good!
