I have a 2016 Vegas 25.2 on a Ford $450 chassis. All Axis and Vegas models are on an E350 or E450 chassis. As per Ford, the engine requires an oil change every 12,000 km (7500 miles) or every 6 months, whichever comes first. So for most of we are changing oil every 6 months no matter what the mileage. Some time before 2016 Ford also changed the oil recommendation to 5/30 for the Super Duties as compared to the previous 5/20. Had a discussion with the dealership that claimed all the V10s use 5/20 but after checking they agreed it is now 5/30. (it says to use 5/30 in at least 5 different location in the owner's manual. Guess they really wanted to make a point). The oil spec is for semi-blend (which is factory fill) or full synthetic but the oil change interval does not change.
