Diesel is very to me and I am by no means a mechanic.
I'm at the dealer today for LOF, nitrogen in tires, repair led light issue, etc.
We have 4550 miles, 7% oil life and "engine will not restart in 430 miles" warning.
Service manager could not find total capacity of DEF tank...I located it on the forum of 8 gallons.
IF this tank was full from manufacturer/dealer...then I have to expect to replenish 8 gallons of DEF per 5-6000 miles?
AT $14.00 per gallon for MOPAR brand, this is a very expensive maintenance item.
Does this seem correct? Or is it just possible the tank was not full?
Not sure if this effects my oil life or DEF usage...but we are towing an RV/trailer weighing about 6,000 pounds in the flat lands of south FL about 5-8% of the time...so not that much.
