Had my first oil change. They forgot to reset the computer. No biggie just surprised that they haven't got this down yet. They also put one of the oil reminder stickers in the window. It called for me to return in 3000 miles. This got me to thinking. You don't suppose that they put the wrong stuff in it?

The invoice identifies 8 quarts of "5127394AA OIL 0W40". My oil changes are free so I don't know what the stuff costs or that would clear it up. Can anyone turn this number into something meaningful?
