The Mileage Monitor is a precision engineered vacuum gage. The instrument itself has no effect on performance or mileage, but if you use the Mileage Monitor as a driving guide, you can achieve a substantial improvement in your gas mileage. If you don't want to install the Mileage Monitor in your vehicle, you can just use it as tool to tune up your engine, for the best mileage. The highest reading indicates the best gas mileage. Normally, driving at a slower speed will get you more miles per gallon, but sometimes increasing your speed a bit will also increase your gas mileage. Just glance at the gage from time to time to see for yourself. People with trucks pulling trailers, motor homes or other gas guzzlers will really appreciate getting the best possible gas mileage. However, any qualified mechanic will verify that a vacuum gage is an extremely valuable tool and can help you spot problems. For example, if the Mileage Monitor shows a steady, but lower than normal reading, your ignition timing could be off, or you could have worn piston rings, or incorrect valve timing, or a leak in the intake manifold. If the needle slowly moves back and forth at idle, your carburetor adjustment is incorrect. If the needle oscillates at idle and then holds steady at higher RPM's you probably have worn valve guides. If the needle is steady at idle and oscillates at high RPM's, the valve springs are probably weak. If the needle oscillates at all RPM's and is more pronounced while cranking or at idle, the valves could be sticking, burnt or leaking. If the needle falls toward zero at high RPM's and the vehicle seems to have no power, you probably have a restriction in the exhaust pipe. If given the choice of only one instrument to spot problems, or tune up an engine, a top mechanic will normally choose a good vacuum gage.
