Anyone know ways to get better fuel economy from cars?

- Keep your tires properly inflated. Avoid those oversized bling-bling rims since they add unnecessary weight and reduce fuel efficiency. - Don't carry unnecessary cargo in your car. - Avoid installing accessories that add weight and affect the car's aerodynamics, such as roof racks and bumper guards. - Avoid over-revving the engine when shifting. - Subscribe to a regular maintenance schedule, and follow it religiously. - When using the car airconditioning, don't set the thermostat all the way high; just select a comfortable level of coldness and keep it there. - Don't let the engine idle for more than 30 seconds. If you're stuck in traffic or a parking queue and you forsee that you won't be getting anywhere for some time, switch the engine off.

You know I was just having a discussion with someone about this the other day. He referred me to this site www.water4gas.com/2008.htm It's a couple books you can read in PDF form. There is a way to make a little device you can add into your car, it creates hydrogen from water and can increase your gas mileage, apparently it helps the fuel burn more efficiently. I haven't done it yet as I found out about it. But I was think about at least building the device to see if can really produce hydrogen. The guy I was talking to said one of his customers told him about it and even built him one of these things. His customer claimed that he has one in he SUV and was able to get an extra 100 miles out of his tank. That would really be impressive if it's true. The only thing that worries me about it, is the reactivity of hydrogen and not wanting it to explode. But the schematics for it includes plans for a release valve that will release the hydrogen so the explosion thing is not an issue. Hope this helps!

I have heard these two tips. Do not carry a lot of heavy items in your car and do not speed.
