Has anyone had issues with their Ecodiesel using oil? I have a 2014 Ram Ecodiesel, and the engine was replaced by the dealer in 2018, so I assume it is a 2018 engine. Late in 2019 I had a delete done (by a local diesel tuner) because I was sick of all the check engine lights and DEF problems. After the delete the truck ran great and fuel mileage improved. However, it really smells like burning oil (like oil dripping on an exhaust pipe) when I come to a stop. I decided to check the oil, just in case, and it was 1 litre low. Since then it has used about a litre every 3,000 km. Now I have another check engine light (PO26c), as well. I examined the entire exterior of the engine for oil leakage on my hoist, and it was bone dry. Anyone have suggestions where the oil is going?
