So Flowerjokes are still finicky about oil? Nothing new.
U could run a Cummins on some goose grease and French fry oil and the only downside is getting hungry when you’re pulling grades and it smells like a fried turkey!
Lol
Run the wrong oil in a 19+ and you may have a cummapart. :E

• 2019 model year, and newer vehicles, it is recommended to use 10W-30 engine oil such as Mopar, Shell Rotella and Shell Rimula that meets FCA Material Standard MS-10902, and the API CK-4 engine oil category is required. Products meeting Cummins CES 20081 may also be used. NOTE: Always refer to service information and/or owner’s manual for exact engine oil recommendations. CAUTION! 15W-40 grade oil CAN NOT be used in any 2019 model year or newer 6.7L equipped vehicles due to the new designed valve train of this engine. If this oil is used, it will cause deposits to form in the Hydraulic Valve Lash Adjusters leading to undesirable noise, and/or engine damage.
May want to pass on the Goose greese going forwards that may cause deposits in the valve lash adjusters. :W
