2019 3.6 V6, 0w20 oil?

[Slow&easy]

Has anyone else read the manual on the 2019 3.6? It calls for 0w20 and I can't find anywhere else it says any other weight is acceptable. My guess is they do this for the auto start to spin the motor easier. I'm due for an oil change and I was going to use 5w30 just like I use in my 2014 3.6.
But now I'm on the fence about using 5w30 since winter is here and it's been cold so far and winter is not even here yet. 0w20 is like water, but on a side note, Honda has been using this weight of oil for years and their motors seem to last. (yes I know most Honda's are not truck motors)

I was told tha tthe 0W20 is a semi-synthetic. So it might negate the use of a heavier oil.

When I went into the dealer for my first oil change I questioned it myself.

My 2018 Pacifica Pentastar specifies 0w20 oil. It now has 30,000 miles on it. I am stil awaiting my PEntastar Longhorn 4wd pickup. It is a lovely engine and the0w20 is a proven oil for the Pentastar engine but use a full synthetic.

Following the Pentastar 3.6,
the 2012 Jeep GC specified 5w-30.
My 2013 Jeep GC specifies 5w-20. (this has 160,000 miles and still running great)
Now my 2019 RAM 1500 specifies 0w-20. (23,000 miles so far)

We used to call this sewing machine oil. I'm using whatever RAM specifies. So far, my oil changes have been done at the dealer because I have some freebies. Pretty soon, I'll change the oil myself.

I just changed the oil in my wife’s 2017 GC with the 3.6 and it uses 6qt of 0w20. I run mobil 1.

What a great motor.

I did an early change at just over 1000 miles and used SuperTech 5-20 full synthetic. It is available at Walmart. I paid $15 each for two 5 qt jugs (but only put in 6 quarts).

A you tube channel called Project Farm did a review of SuperTech and it did pretty well. I change at 5,000 mile intervals, normally.

Please don't put 6 quarts in your 5th gen Pentastar. They require 5 quarts.

 

[JimD007]

You need to double check your source. My manual definitely says 6 quarts for the 3.6.

You might be low on oil.

Sounds like there might be a difference between the DS and DT oil capacities. Can we confirm this to alleviate further confusion? I will double check but I am 99% sure my manual for my DT says 5 quarts, that was a big selling point for me when I purchased it.

 

[JimD007]

It is possible that the recommendation varies between the classic, which I have, and the newer model. But my manual says 6 quarts of 5W20 (not 0W-20). The fill port cover on the engine also says 5w-20.

 

[KeithStone76]

Mine says 6 quarts of 5W-20. Interesting.

Y'all know that at anything over about 50 degrees Farenheit, 5W-20 and 0W-20 have the same viscosity. The 0 is the cold temperature rating. At summer temperatures they behave the same with equal viscosity.

 

[19jds76]

Here ya go, right out of my manual........

 

[JimD007]

Curious. It appears at some point RAM changed the amount and viscosity recommended. That makes me curious if the engine changed, probably the sump. Mine has a small steel pan bolted to the aluminum block. Something like that could change, I guess. If it is a different sump, you definitely would not want to use 6 quarts when 5 are recommended. I did not buy my 2019 until December but could have been on the lot for awhile.

More specifically, 0W oils are rated with a lower pour point to increase flow in colder temperatures. In most other specifications they are the same as 5W rated motor oils. For that reason they are almost always full synthetic. In some cases 0W oils have a higher viscosity index (VI).

The oil change is to accomodate the cam phasers. Both intake and exhaust cams now change their timing.

Pour point has nothing to do with the winter rating. There is no minimum/maximum pour point limits set by the SAE and there is no pour point sequence test required by the API. Depending on the base stock and pour point depressant used by the blender it's possible for a 5W to have a lower pour point than a 0W. For example, Valvoline Advanced Synthetic 0W-20 has a pour point of -39C while Pennzoil Platinum 5W-20 is -48C and Mobil1 5W-20 is -51C. SAE J300 defines the viscosity requirements for engine oils and pour point is not part of the testing.

Pour point is pretty useless and was dropped by the API many years ago. An oils winter rating is determined by how it performs in the Cold Cranking Simulator (CCS) and the Mini-Rotary Viscometer (MRV) tests, both of which have maximum viscosity limits at various temperatures. For example, 0W oils cannot exceed 6200 centipoise (cP) at -35C and 5W oils cannot exceed 6600 cP at -30C in order to pass the CCS test.

Amazing how old threads can be woken up from their slumber..

Okay, thank you for the comment. My earlier response was meant to be a general comment, however I see now it was over broad. May I assume they still spec Low Vis at 82 and 212F, and do they rely ASTM D97 and D2602?
