Brady gave you good advice, however, I did what he implies is not doing it right.
6 mos after my 2016 was delivered I installed Hell Bent 2" Front Leveling Spacer Set #125-200-001 .
After a couple of years, because the forum experts said what I did would fail, I bought a set of Billsteins and a...
I've always used Ram's recommended Rotella T-6, 5w-40.
In April 2023 a member of another forum called VM Motori, the Ecodiesel manufacturer, he asked them what is the best oil for his Ecodiesel. They said: Synthetic European oil, MS-12991, 5w-40. MS-12991 is the important factor. So I have...
Drive it without any worry.
The Ecodeisel CP4 pump recall results from the pump being a problem on the Cummins engines. NHTSA caused that safety recall. Then, because the Ecodiesel was using the same pump, even though its failure rate was less than 1%, the Z46 recall was issued.
I can't help as I removed the cover right after I bought the truck
I have seen some creative designs and paint jobs on Eco engine covers
Anxious to see what you do with yours
What is the gain over using Ram's recommended oil? I see no reason to deviate. And how does he know that the 15w-20 is giving "no ill reactions"? He won't know until he has a problem
Welcome
You are not being "blown off". It's the HPFP Z46 safety recall, it has to be done. You will get a letter saying the parts are available, it may take awhile
Ecodiesel vehicles built before June 2016 specs were changed in June 2016 to use 5w-40 oil and recommended Rotella T-6 or equivalent. Engine failures have nothing to do with brands of oil, only viscosity.
The best fossil fuel available has less lubricity than European fuel and the quality varies considerably in many areas. It has been attributed to the CP4 failures, thus the recommendations to use a lubricity-adding additive.
