I have seen that several people have had issues with the dealer an their warranty. I haven't seen the Magnuson–Moss Warranty Act mentioned once yet.
Being a Harley Davidson Motorcycle rider there have been discussions upon discussions about denial of warranty service due to fluids, non-Harley branded parts, etc. Harley is famous for trying to avoid warranty repairs to major issues with their bikes by denying repairs for unrelated maintenance or aftermarket parts (including fluids).
Under Magnuson–Moss Warranty Act It is against Federal law for an original equipment manufacturer (OEM) to deny warranty coverage based solely on the brand of lubricant used. (Assuming the brand of lubricant is equal to the required specs). The manufacturer or dealer must show that the aftermarket or recycled part caused the need for repairs before denying warranty coverage. (http://www.ftc.gov/bcp/edu/pubs/consumer/alerts/alt192.shtm).
I would not take a twisted Styrofoam cup or the word of the dealer that DEF is bad without documentation. And it is up to you to keep your receipts to prove the other way that what you purchased was indeed what is spec'ed for your engine.
Next time you come up against a dealer telling you something you know is not right you should bring up this act first if you have your documentation behind you.
