Re: More Mileage for Hummers?
I've never seen a nationally recognized testing lab post positive results from any of these devices. I haven't seen these, but I suspect they only lighten your wallet.
Consumer Reports did some testing on the usual suspects in June:

Less weight = more MPG. That is how it works, then! Quote:

Seriously though, I wouldn't mind trying one. Mythbusters did a show on things to increase fuel economy, but unfortunately, these types of devices were not tested.
I wouldn't mind trying them with the money-back guarantee, though if they twiddle their thumbs and take their time getting the money back to the purchaser, that sucks.
I've heard a lot of negative things about similar products in the past, but I'd like to see for myself.

You should have ordered 10. Quote:
