19 out of 20 people will ONLY BUY the oil grade listed in the owners manual... and really, why shouldn't they? Most don't know the difference between a 0w20 and a 20w50, nor do they care to learn...
So why would an oil company recommend something different from the manufacturer, knowing full well that most people will never step outside the factory recommended grade anyway...
Yes, but they did.
