Abstract: A polymeric lubricating oil additive containing pendant perfluoroaliphatic ester groups that behave as a fuel economy enhancer when added to lubricating oil compositions. The additive is prepared by the process which comprises reacting a perfluoroaliphatic alcohol with an alkenyl succinic acid anhydride to form a alakenyl succinic mono and/or diester in the presence of an acid catalyst.

Abstract: A polymeric lubricating oil additive containing pendant perfluoroaliphatic urethane units that behaves as a VI Improver and a fuel economy enhancer when added to lubricating oil compositions. The polymeric substrate may be a copolymer of 15-85 mole % ethylene and propylene or a terpolymer of 15-85 mole % ethylene, propylene, and 20-80 mole % of a non-conjugated diene or triene (C.sub.3 -C.sub.10) alpha olefin. The copolymer or terpolymer substrate has a molecular weight range of about 5,000 to about 500,000. A graft copolymer or terpolymer containing pendant isocyanate groups is prepared by reacting the ethylene propylene co- or terpolymer with an acrylating agent. Post-reacting the copolymer or terpolymer containing the pendant isocyanate group with a perfluoroaliphatic alcohol generates the additive.

Abstract: A remote, manual shift system cooperating with the clutch, throttle and gear shift stick of a manual transmission vehicle for use during engine testing includes a series of five sensors, one each for vehicle speed, throttle position, clutch position, X-axis gear shift position and Y-axis gear shift position. These five sensors are operable to record and compile actual drive test data reflecting the actual operation of the vehicle during the test drive. This data is recorded and the recording is then processed by an electronics circuit which in turn provides actuating signals of a DC voltage level to a series of servos which are arranged in mechanical combination with the clutch, throttle and gear shift stick of the vehicle under test. As these various servos are actuated with an appropriate input signal, they perform the shifting from one gear to the next gear along with proper depression of the clutch and acceleration by means of the throttle.

Abstract: A nitrogen-boron-containing lubricant additive characterized by containing from 0.5 to 2.5 weight percent nitrogen and from 0.050 to 2.0 weight percent boron and a mineral lubricating oil composition containing same.

Abstract: The reaction product of a dehydrohalogenated polyalkene and a maleic anhydride prepared by the method comprising halogenating polyalkene, dehydrohalogenating the resultant halogenated polyalkene and reacting the formed dehydrohalogenated polyalkene with maleic anhydride; the derivative of said reaction product and alkylene polyamine having detergent-dispersant properties in oil and hydrocarbon lubricating oil compositions containing said derivative.
