I bought my 2021 Ram 2500 in September 2021. It was my first brand new truck and when I saw what the dealer was charging for oil changes, I knew there was no way I was going to have them work on my truck – I’ve always done my own work but because this may well be my one and only new truck, I knew I better do some homework.
First off, I did not want to void my warranty. In talking with the dealership their recommendation was that I only use Dodge/Mopar brand oil filters and Pennzoil Platinum 0w40 engine oil plus I should keep a log of when I changed the oil, filter and with what. Okay I thought – I can do that.
This is a great example of where the Internet and the web can just drive you nuts. If you search about what oil and filter to use, you will get just a ton of search results with guys offering up their weird home brew concoctions, using different weights, brands, etc. That was all fine and dandy but I did not want to void my warranty or give a dealership some excuse to charge me because I didn’t use the approved oil.
Which filter does it use?
If you want to stick with factory parts to avoid warranty headaches, you need the Mopar MO-339 filter. I am using the 04892339AB but am told there is now an AC part number. Regardless of the letters, I would not be concerned if searching turned up an AA, AB or AC. The main thing is that the correct model is MO-339.
Where can you find the Pennzoil Ultra Platinum Full Synthetic 0W40 Oil?
You are going to need 7 quarts of oil if you change the filter and I always change the oil and the filter. I am used to walking into Autozone, O’Reilly’s or Walmart and buying oil. They do not carry this weird Pennzoil “Ultra Platinum Full Synthetic” 0W40 that Dodge was specifying. Apparently there were some office politics about switching to Pennzoil and to lock people into using Pennzoil plus being more likely to go to the dealership for oil changes they (I’m not entirely sure who “they” are but will blame both Dodge and Pennzoil) – they came up with this odd spec that really wasn’t required. Stuff like that irritates the hell out of me – they could have specified something else and made it easier for all of us.
At any rate, as mentioned, I am sticking with what Dodge specifies through the warranty period. The dealership will usually sell it but do you know where I found it and at a far better price? Amazon – yeah, Amazon. It’s the cheapest and most convenient source I have found and is also why you will find thousands of reviews. Again, remember you will need 7 quarts.
Quick comment on my experience so far
My first oil change some time late last year was quite an experience. The oil filter had “factory installed” printed on it and boy, it did not want to come off. I wound up using a vise-grip type oil filter wrench to get a good enough hold to finally break the seal and spin it off.
I just did my second oil change getting ready for Winter and rotated the tires also [click here for a post about how to do that the easy way]. I figured I would take a minute and share with you where to buy the filter and oil from and hope this helps you out.
By the way, the torque spec for the oil drain plug is 20 foot pounds. Now I know some guys just feel how tight to go by hand and I did that for over 30 years but now do to nerve and muscle damage, I can’t tell how tight I am pulling so I torque to spec – totally up to you.
Note, I have to buy all of my parts – nothing here was paid for by sponsors, etc. I do make a small amount if you click on an ad and buy something but that is it. You’re getting my real opinion on stuff.
