Abstract: Instant Reading Oil Dipstick Improvements is a near universal design with most assembly done by the manufacturer. The customers can easily adapt such to match their existing dipstick geometry by pushing the adjustable parts to the correct location, where they will remain. The air valve is within a single, machined brass cone that adapts to the metal tube and seals in the engine vacuum. A new tubular plastic air seal around the wire handle increases reliability. And a cone shaped rubber squeegee will automatically remove oil from the outside of the tubing as the dipstick is withdrawn from the crankcase.

Abstract: The present instant reading oil dipstick automatically extracts a representative column of oil from the crankcase oil reservoir. Such is done inside of a translucent fluoroplastic tube. A machined brass slide valve, with sealing O-rings, fits inside of the metal dipstick tubing leading into the engine crankcase. When the dipstick is withdrawn for checking oil level, the slide valve automatically closes over an air vent in the plastic tubing, thus preventing the oil that is inside the bottom of the tubing from running out. The oil level can be ascertained, easily—even in low light levels—without having to wipe off the oil from the outside of the dipstick, and without having to reinsert the dipstick one or more times.

Abstract: Traditional mechanical fuel gauges do not provide an accurate measurement of a vehicle's fuel capacity. As a result, vehicle manufacturer's incur considerable losses when delivering cars with unused fuel. The present invention, therefore, provides a method and system for accurately determining an amount of fuel required to transport a vehicle a known distance. This is achieved by utilizing a fuel measurement device (FMD) which can be inserted into a vehicles fuel tank. Upon removing the FMD from the fuel tank, one can then determine the amount of fuel that is required to travel a particular distance at a particular fuel consumption rate. In a preferred embodiment of the invention, the FMD is held by a holding device. The purpose of the holding device is to minimize the size of the FMD such that the FMD can be disposed of with minimal waste.
