and holy crap and did not know FCP did exchanges on oil! I would have been doing that for the past 14 years with my 740's. I have to make sure I can change my own with my current warranty. I know for my last warranty They did not except you changing your own oil, even if you had the receipts. Funny thing is for that car (GMC Yukon) I still take it to the dealer for oil changes instead of doing it myself. I can't buy the oil and filter for the price they do it. cost is around $50 for 8 or so quarts of full synthetic, oil filter, and tire rotation.
