I have yet to see any of you guys product any scientific evidence that proves that one national brand is better than another. Everyone just says they 'feel' or 'notice' a difference. Please! Why is Shell the best? Because it sponsors Ferrari F1 and had Ferrari F1s running through Monaco and Rome streets in last summer's commercials? I'm not being cynical. I'm open to the idea of one being better than the other. Provide me scientific proof, dammit!
