Method and apparatus for determining engine oil change intervals according to actual engine use

Engine lubricating oil temperature and the amount of engine usage are used to calculate when engine lubricating oil has reached the end of its predicted wear life. Each spark (engine speed) pulse is multiplied by weighting factors that are periodically determined by sampling the engine oil temperatu...
