You're doing it wrong
Yea he tried making it clear the grid heater bolt has nothing to do with the oil changes but they are so much like robots these days its like talking to a brick wall..That's frustrating on the warranty coverage for him. I had a little bit of a battle too as I did my own oil changes. To me, the maintenence is irrelevant for a grid heater failure. I understand for the lifter failures why they want oil records given the oil requirement change for the 19+ trucks.
