I recently had he oil changed in my 2008 D3500 Cummins at one of the local Dodge dealerships.
I was told they had nothing but synthetic oils.
Getting hard to find conventional oil in parts stores, unless you buy the house brand (NAPA, Fram).
This is very true - products in general. I use Castrol Syntec 0W40 for my 2016 Challenger Scat Pack & cannot find it in any stores around me. I just ordered two jugs of it online today through Amazon. Hey - what are you gonna do? I prefer to support brick & mortar, but they ain't got!
Syntec name has been discontinued. Edge is the top of the line Castrol now. Ask them for the European stuff. May have it stuck somewhere other than the oil racks if it's not out front. Use part numbers. Works better than descriptions for some of the counter monkeys.
5W40 may be easier to find.
