I hope to see an MPG increase, but if I see her van running nice and not burning as much oil, that is also a positive for me. So I plan on being as scientific as I can.

With such slight claimed increases you are going to need better control over your subject. How will you control fuel brand/octane? Ambient temperature variations? Vehicle condition?
