Was Winston Cup Bull Racing a Miller Lite commercial?

In this commercial for Miller Lite, Dick Van Dyke and Mary Tyler Moore can't decide whether to watch NASCAR or bull riding on television. "Let's Watch Both", Dick Van Dyke says as he whacks the television set with a bottle of Miller Lite as a program called Winston Cup Bull Racing is shown. The announcer explains that if you can combine great taste and less filling you can combine anything.
