My 2021 RAM 3500 HO now has 5500 miles on the ODO. This is my first DEF vehicle and I have to say I'm very surprised at the rate I'm burning DEF.
I've read other posts and it seems like I'm running about the same rate as others but much higher than my friends 2500 Ford. It looks like he's getting about 2.5times the miles I see on my truck. He has a 7gal DEF tank and only fills every 5000 miles, during regular service.
I just had the first oil change to flush the factory stuff and the dealer said my truck is running correctly.
Does anyone know it there is a software revision/TSB out there or coming to address this?
TIA
