I found a simple way to increase my mileage. Less then half the combustible components in gasoline are burned in a conventional engine. If you cycle this back to the engine, it can increase the efficiency of the engine and significantly increase your mileage.
I use a high heat poly-carbide hose to return unburned fuel to the intake.
My mileage has gone from 19.4 MPG to 39.9 MPG
