Q. Do you guys know the engine-oil capacity for a 2002 Ford F-250 Super Duty crew cab with a 6.8-liter V-10 engine? The owner’s manual says the engine takes six quarts. Another dealer tells me it takes six and a half quarts. My local technician tells me six quarts don’t quite fill it, so he adds a seventh, which brings it up just above MAX when he changes it.
I recall there was controversy over this issue when the engine came out. There were mis-calibrated dipsticks and the like. What is the proper capacity of the engine?

A. According to my technical source at Ford, all of the V-10 6.8L engines have a six-quart oil capacity with filter change.
