Here is what Ford requires for their vehicle repurchase program:
Oil and Filter Requirements
Scheduled oil and filter change intervals are required for all vehicles at 5,000 miles.
· A $15 credit for each eligible repurchase vehicle will be paid to accounts for oil and
filter changes made at 5,000 mile intervals. (Oil must meet Ford specifications.
Filters must be Motorcraft).
· Accounts must provide Ford Motor Company evidence that the oil/filter changes
were completed; stickers, initialed by the person making the oil change, must include
date and odometer reading at time of each oil change and must be placed on the
driver's side "B" pillar (not on top of each other). Vehicles returned without an oil
change will be permanently rejected from the program.
· All required campaigns must have been completed along with normal maintenance,
including scheduled oil and filter changes at 5,000-mile intervals (see chart below).
Vehicles indicating evidence of non-adherence to these scheduled changes will be
rejected without exception.
