Acetone in your gas

[Gizmokid2005]

If you really want to get down to fuel milage.
remove any electronics that aren't needed for operation.
remove your AC compressor, power steering pump, spare tire, un-necessary fluids, any un-used equipment in the vehicle (ABS, traction control, back seats, etc). finally, keep a minimum amount of fuel to get you where your going.
Basically, the lighter you can get the vehicle, the better.
The less electronics, the less the alternator has to work and that is the less the engine has to work to generate electricity.

Me personally, Im gonna smile at my 20 mpg and drive my truck like I have a place to go.

x2...I'm going to smile at my 19mpg and just keep on going.

My trike gets 50 mpg and my bug gets 30 mpg so I'm happy with that However I do prefer a little acetone in my fingernail polish remover ... works much better than the non-acetone one
