I have a 1993 Chevy Work I bought new,free oil change (Quaker State oil) for as long as you own your vehicle.
I go to the dealer in the winter time to get the free oil change,oil changed get ready to leave,they hand me a bill for about $20 dollars,I say why? They say the oil is free,the filter is $13.00 dollars,paper towels are $2.00 dollars,and about $5.00 dollars for clean up because the truck had some ice an snow under the truck they had to deal with.
What a gimmick
(not to mention the hour or so I had to wait to get the oil changed,never again.)
