I changed my oil myself at 1000 miles. I used a Mopar Filter and the European FS 5w-40.
1,000 miles is a little too soon for me. The owner's manual said it can take a few thousand miles before the engine stops consuming oil. I'll probably have the factory fill changed at 4,000 miles. I've had the truck since August, but due to COVID-19, I was working from home and haven't had the opportunity to drive it as much. I've done a lot of towing with the 2015 since the 2020 wasn't broke-in for the first 5 months I owned it. Life will get a little more normal in the coming months, so I expect we'll drive the 2020 a lot more.

I have 3600 miles and I drive under 5000 miles a year so I will just change it yearly. When I change it I will post a UOA. I follow this site for the EcoDiesel.
Annual oil changes are perfect for low mileage oil intervals. We'll be looking forward to seeing your UOA results.

I actually own a 2020 Wrangler Unlimited WILLYS ECODIESEL. Same engine a little less torque than the Ram. Some of the components are moved around, but I haven’t had one problem with it.
Nice! I would love to have a Gladiator EcoDiesel, but my wife wants the Wrangler. I'm not sure what we'll end up doing, though. For sure, we won't make any more vehicle purchases until late 2022 (order a 2023 model).

You all seem very knowledgeable about these different oils. I am older guy so i am not up with all the new oils. I have used Schaefer oil since 2006. Am I able to put Schaefer 5w-40 diesel oil in my 2020 Ecodiesel ? Please simplify the responses. Thank you in adavance
Schaeffer said no when I asked them.

I did my first change on the truck late, 562 miles, because I had to wait for a filter. The Jeep was right at 300 miles...

I love our Jeep. I have 37” tires on it and still get 23mpg. The torque is unbelievable in such a small vehicle.

Ok, that was a lot of reading! New owner of a 2021 Ecodiesel, just came from a 2019 Cummins. I plan on doing 5k oil changes and 10k fuel filter changes. I don’t want trouble with this little engine; I like it so far!

So, to summarize, it seems the Amsoil FS European 5w40 is the best oil, and the Mopar filter for both fuel and oil. Dieselfiltersite is the best place for those, and Amsoil you buy direct?

Thanks

If you send me a private message, I can give you my dealer's information. He can get it to you for a good price. He already sells to a lot of EcoDiesel owners, so he's got a lot of good information.

I have a Jeep Wrangler Unlimited EcoDiesel and I use the Signature Series Amsoil 5w-40 diesel oil. I haven’t had one problem using this oil. I don’t buy in to all the MS-12991 crap. I’m sure there will be negative comments saying my oil doesn’t meet the spec. I believe any low ash diesel oil will work. Use what your comfortable with. I changed my oil out at 1000 miles and replaced it and I haven’t had one problem.

It’s yours - you are welcome to use what you want - unicorn tears and dragon piss if you like. Nobody cares. For those looking for options compatible with the factory specifications - we contacted nearly every major oil supplier with an oil available in the states, and asked - and the list is posted.

This is the Mopar oil with part no. on your list. The dealer couldn’t confirm it’s synthetic. He wanted $14 per quart. Is this synthetic?
Also same dealer said he has been using Shell Rotella T6 which does not appear to meet the specs.

I've only seen one engine failure in a 2020+ truck, and it was an owner that let their dealer put T6 in the engine. You better educate your dealer.

Recommendation: Do NOT rely solely on this list. Always double check to make sure the following oils are current in meeting factory specifications.

The new 3rd gen (2020+) EcoDiesel has different specs than the 2nd generation (2014 - 2019) engine. The following oils have been known to meet the new MS-12991 and API SN Certification/Standard/Approval. I put them in order based on what I think are more 'commonly known', not based on preference or performance.

Mopar 68231020AA 5W-40
Pennzoil Platinum Euro 5W-40
Valvoline European Vehicle 5W-40
Quaker State Ultimate Durability EURO 5W-40
Havoline ProDS 5W-40
Amsoil 5W-40 FS Synthetic European (EFM)
Redline Full Synthetic 5W-40
Motul 8100 X-cess 5W-40
Liqui Moly Leichtlauf High Tech 5W-40
TRIAX Euro LX 5W-40
TRIAX Euro Ultra VX 5W-40
Ravenol VST 5W-40
Total Quartz 9000 5W-40
ELF Evolution 900 SXR 5W-40
ELF Evolution 900 FT 5W-40
AMALIE Elixir Full Synthetic Euro 5W-40
Millers Oil Trident Fully Synthetic 5W-40
Millers Oils XF LONGLIFE 5W-40
MPT Thirty-K True Synthetic High Performance 5W-40
CAM2 Blue Blood Elite Euro 5W-40
FUCHS TITAN Supersyn SAE 5W-40
Lubrication Engineers 5w40 Monolec Ultra Syn Heavy Duty Engine Oil
REPSOL ELITE COSMOS HIGH PERFORMANCE 5W-40


I will update this thread as new approved oils are added.
Thanks Biodiesel. I trust you and bought the LiquiMoly Leichtlauf High Tech locally for $41 for 5.28 quarts. Made the first oil change at 7,100 miles. Thanks for your help

That's a very good brand of oil. If possible, take an oil sample for us towards the end of your interval.
