don't confuse the three point oh echodiesel with the Cummins 6.7

Its a temperature thing on the 6.7 . 0 degrees or below its 5W40, above 0 degrees 15W40 is okay. PER THE MANUAL !!!!

I think FCA is recognizing that synthetics are better than conventional. But they promote only Shell & Pennzoil products. And since Pennzoil/Shell doesn't make a 15w 40 synthetic, FCA promotes the 5w 40 they do offer?

My manual says nothing about Cummins specs. Just Mopar specs. And doesn't recommend a brand. But does day 15w 40 above zero and 5w 40 below

true dat but Big Hips had referenced the 3.0 OM and not the 6.7 OM therefore my comment on preferred viscosity. . LOL

no, its true that Mopar doesn't mention the same stuff that Cummins does, but those who have access to Cummins info know the FCA doesn't seem to be proactive in re writing their manuals to reflect what Cummins now recommends.. anyway, CK$ oils with the CES 20086 rating supercedes and is an improvement upon CJ4 oils with the CES 20081 rating and the newer oil is backwards compatible.

copy that, I had the wrong one....thanks for the catch!!

I have always ran 15-40 in my Cummins engines. NEVER have or wanted to live in 0 or lower temps!

Apparently, Car quest synthetic oil available in Florida is now sourced from Amalie oil Co

They have a funny motto. "Better than it has to be".

No marketing overkill there!

If you look at the chart above, the cold flow for 15w40 is about 5 above and the cold flow for 5w40 is about 15 below. I remember when I first started changing my oil, the Amsoil recommendation was 15w40. Then one day it was 5w40. So I'v been using that ever since.

Tonight I went back and dug around the site and discovered that Amsoil recommends 15w40 for years 2010 and older. And 5w40 for years 2011 and up.

There. MY mystery solved. :-laf

Does anyone actually make a 0w 40?

Never actually laid my eyes on that

Newsa, you and I don't need to worry about that but to answer your questions, yes they make 0-40. https://www.mobil.com/english-gb/passenger-vehicle-lube/pds/euxxmobil-1-turbo-diesel-0w40

That mobile 1. 0w 40 has a cold pour point of -54 F. Redline 15w-40 has a cold pour point of -49F. Seems like there are plenty of arctic options?

Newsa, this is Cummins recommended oil viscosity chart for temp range. its not like you are I really have to worry about -54 degrees. never get the engine started at those temperatures if it was let to sit outside for any length of time anyway so its sort of a moot point for just about anybody what the pour point it

After reading this entire thread..... synthetic is good......Dino is ok.......and the TDR eats it’s own members. Say no to cannibalism! :-laf

In late Dec (4 months ago) I was in Illinois and saw negative 17° (-17)F on my EVIC. Never say never. I had 5w 40 in my truck. But after I got up there and did some research, I discovered a high quality 15w-40 has the same cold flow charcaterisitcs as some of the cheaper 5w-40's.

A little more research showed a website of a lube manufacturer saying that as long as the temp is 20°F above the cold pour point, it should flow adequately on cold start. I was plugging in the truck (block heater) on those coldest mornings. That probably helped the oil flow once it was picked up.

Newsa, one time it got so cold out here by the Panther Refuge that my EVIC told me I had to wait to start because the Pre heat was in progress. musta been the most miserable 20 seconds of my trucks life
