Pretty much the only oil that's approved that you can find, without paying a fortune for individual quarts, and with the way FCA/Stellantis has change the recommended oil several times over the years, first they required a fiat approval that was essentially ACEA C3, then they said use Cummins approved CK-4 oil, then they landed on using oil that meets MS-12991, which is a little weird as it's still a full SAPS A3/B4 Euro oil on a vehicle with a DPF although the as is lower at 1.13% compared to some other "full SAPS" Euro oils, but it's what they say to use and these engines are notorious for all kinds of problems so I'd only used the approved oil in case you have an warranty issues come up.This will likely be what goes in the EcoD as soon as the factory fill has done its job. Nice find!
I did a lot - I mean, a LOT - of reading on these EcoD's and it seems that this latest gen engine has been mostly redesigned to cure the problems of the past two versions. Of course, new parts and designs come with new problems, so until people have racked up mostly trouble-free miles on them we won't really know.Pretty much the only oil that's approved that you can find, without paying a fortune for individual quarts, and with the way FCA/Stellantis has change the recommended oil several times over the years, first they required a fiat approval that was essentially ACEA C3, then they said use Cummins approved CK-4 oil, then they landed on using oil that meets MS-12991, which is a little weird as it's still a full SAPS A3/B4 Euro oil on a vehicle with a DPF although the as is lower at 1.13% compared to some other "full SAPS" Euro oils, but it's what they say to use and these engines are notorious for all kinds of problems so I'd only used the approved oil in case you have an warranty issues come up.
My WM barely had any oil on the shelf. I was looking for M1 euro 5/40. Ended up with Castrol 5 40They still have 4-5 quart jugs of QSUD 5-40 for $18.97 at my local Walmart.
Try walmart.com it is in and out of stock regularly, usually out when they drop the price to <$19.My WM barely had any oil on the shelf. I was looking for M1 euro 5/40. Ended up with Castrol 5 40
Dang, missed it.I just saw Mobil 1 at Walmart.com 3 pack of 5 qt jugs for $25. I guess that's a pricing error but a better deal than the QS for a solid 5W40 for sure!
