I have been running diesels for over 20 years with most all brands offered here in the US my 2018 Ram eco diesel lost at least 4 miles per gallon right after it hit 50k miles I don’t believe in coincidence and this this to be suspicious has this happen to anyone else? I have checked everything that might be the cause and nothing points to ten problem no issues what so ever with this truck until now have put about 1500 miles on it since this started and 22-23 highway driving way too easy and before was getting 26-27.5 highway consistently keep all records so I know what actual mileage I was getting never been t dealer either so no reflashes have Been done any help will be greatly appreciated
