I just got a mailer from ford today for owners advantage and it's giving me a an oil change of synthetic motor craft oil and filter up to 5 quarts for $34.95. Since it doesn't exclude any specific synthetic or vehicle. I would really like to take advantage of it and I know the boss takes more than 5 quarts which I'm ok paying over. My big question is has anyone had luck with these owner advantage rewards on oil changes for the boss?
