The TSB that warns about not using 15-40 in the 19+ trucks says use 10-30 if lowest temperature is above 0. In temperatures below 0 use 5-40 but 5-40 is fine in summer time temperatures also. This is not the exact wording but I couldn’t find the TSB to post again. It never gets to 0 here or anywhere I travel to when I’m there but I do regularly see 100+ degree days and that’s when I do my towing. I asked the service manager at the dealership “What grade of oil do I need to run in this truck?” He said “5w-40 Synthetic year round”. I was glad to oblige. If you want to run 10-30 it is acceptable. Without UOA’s from hundreds of vehicles running the two different grades to compare, it’s a moot point to argue for one over the other. I think the number of automatic regens should be taken into account when deciding how long to run the oil before changing though.

Always Valvoline Extreme Blue 5w-40 and a Mopar oil filter for me. Had to do a Rotella T6 once, still no noticeable change or issue. Blackstone Labs oil report at 30k, they essentially said looks good, barely broken in yet.

I’ve never understood why people run a bottom shelf oil filter with a mid to upper shelf oils.

Just about any oil filter is better than the Mopar one, aside from the P558615 being worse and the Wix 57620 being the same.

It does meet the intent of the warranty, but for the price or OEM there are better options.

I use the LF 16035 FleetGuard filter on my truck but I do have an LF 3972 (same as MO-285) that I keep with me while traveling. I know several people who have used the Quicky Lube oil and filters for the life of their trucks and all of them have over 300k on them. I realize the 19+ trucks are different animals and the other ones are deleted and that makes a huge difference. The 15k oil changes are maximum, best scenario limits. Frequent oil and filter changes hurts nothing but your wallet.

These engines certainly aren’t known for being sensitive to oil, even the CGI motors.

Can you break this down in laymans terms? I dont know what any of this means but interested in understanding which of these filters is good vs bad

The lowest micron rating at the highest filtration is the best filtration efficiency. Synthetic media is also generally better than cellulose (paper) media.

So the Donaldson P558615 is the least efficient filter on the list and the Donaldson DBL7349 is the most efficient.

You are missing the best FRAM filter! Lol

It’s been a while since I compiled that data, but I’m going to guess that was intentional :D
Its a terrible filter but its nice to remove with the bedliner grip lol

Fleetguard LF16035 vs Amsoil Ea080. Looks like the Amsoil is slightly better, but I’ve read in the last few years that the Amsoil filter quality is not like it used to be. Any truth to that? I’ve always ran Fleetguard filter, but always curious about Amsoil Filter. Possibly order the filter with my next oil change with my Amsoil order.

I use Amsoil filters on my other 3 rigs and have had zero quality issues.

It been years since I used an Amsoil on my Cummins, but that’s only because the EaO80 used to be a DBL7349 with a different wrapper and even as an Amsoil dealer I could get the Donaldson filter cheaper. Now that Amsoil doesn’t use Donaldson the Donaldson media is better, and it’s the filter I still use.

I think the Amsoil filter is now being made by Champ Labs who also makes Royal Purple and the media for the Fram Endurance filters.

I haven’t done much research to back it, but I understand they went in-house with their filter production.

The Fram filters for our trucks don’t have as many or as big of entrance holes on top of the filter as the FleetGuard have. It has been argued that that has no effect on the oil flow because of the positive displacement oil pump. But I think it’s done purposely to lower the differential pressure inside of the filter itself. Idk. Lots of people use them but not me.

To add another interesting fact, the Fleetguard filters aren’t rated to support the advertised flow of the oil pump.
