Just an update. I called corporate in Florida and was immediately called back by a gentleman named Chuck. He was friendly and helpful but still backed the store by telling me my vehicle required synthetic oil. He did say they would honor the coupon and change with synthetic for the coupon price. Too late now. If they would have done that before the big blowout this all could have been avoided. I told him no thanks i am not interested in going back to that store even if it was free.
