I bought mine used from an independent wholesaler and it had just been in service 12 months, oil life indicater said 51% oil life left but I took it in to Lund Cadillac in Phoenix and they did the oil change for free due to it being 12 months. No charge to transfer the warranty. Free oil change, free Starbucks, free donuts and a free car wash. Wish they would make the payments for me :bigroll:upstate said:I bought mine as a certifed used Caddy. I know I get the full factory warrenty benefit and that includes the oil changes but my question is does that extend to the full 6 years 100,000 miles that Cadillac warrenties my car?
