Abstract: The present invention relates to dispersion of surface modified inorganic particles including (a) fluid comprising a complexing agent, and (b) the surface modified inorganic particles comprising polyvalent metal ions.

Abstract: Method for determining the performance of a motor vehicle consumable, including engine lubricant, fuel and tires in a motor vehicle having an engine with at least one fuel injection valve, a lubricating system and a CANbus network having at least three network nodes, each operably connected to a computer. The method includes operating the vehicle while supplying the engine with fuel through a fuel injection valve and lubricating the engine with the engine lubricant. A first CANbus network node transmits to the computer a signal indicative of the engine fuelling rate based upon the opening time of a fuel injection valve. One or more second CANbus network nodes transmit signals to the computer indicative of one or more variables indicative of the power output of the engine, and one or more third CANbus network nodes transmit signals to the computer indicative of the vehicle operating conditions.
