Whoa, that sounds a little suspect! Did your friend keep receipts from his oil changes? (Oil, filters, etc...) Many DIY'ers have issues with extended warranty companies and dealerships regarding routine maintenance. As long as you keep good records and follow manufacturer service intervals your friend's claim shouldn't have been denied per Magnuson-Moss Act.
