I'll have to ask. It has less than 7,000 miles, and he uses the trucks computerized "oil life" system to dictate when he changes oil. Unless there was a something like a 500 mile service, it may have never had the oil changed. I'll find out... Edit: I'm really more interested to know if it's a known/documented problem so he doesn't get BS'd by the dealer when he takes it in. It's under warranty, so they'll fix whatever it is if they take the time to duplicate the problem. Regardless, I'll get the answer to your question.
