I ran across an electonic item called the digital fuel mizer. It has six lights (2 red, 2 yellow, and 2 green) that are supposed to let you know when you are getting your best mileage, green lights being the best. Has anyone had any experience using this type of item?

Never herd of that but I would bet you could do better watching the RPM's you're spinning. The lower the RPM's the better the fuel economy.

I agree with tlperry. Kinda seems like a gimick.

I've got an alternate version of that. It's called "my right foot" and my "left ear".I pretty much know if I'm getting on it and how that affects everything.
