I took the pickup to the Ford dealer in Silsbee, Texas. Their tech checked the oil and found that it was high. They called the Mankato, Minnesota (home) dealer and the service writer suggested that they just change the filter, which would take out about a quart. Neither Silsbee Ford nor I thought that was a sensible solution, since we really did not know how much over it was. Silsbee estimated two quarts.

The Silsbee dealer changed the oil. I asked if they could collect it to see how much was actually in there, but they said it would not be possible.

They added 13 quarts, and the resulting oil leve was halfway between the two holes at the end of the dipstick.

Supposedly the home dealer will reimburse me for the oil change, but not for certain yet.
