Got Proof? I say a pump calculated 0.2mpg increase isn't enough to consider the 0w oil as a sucesss. The 0w is for cold flow, not fuel economy. I wish people would stop repeating this nonsense. The number AFTER the W is what effects fuel economy, after both the engine and oil are up to operating temp.
Thank you, okay.
