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...

| description | 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 temperature and the length of time the engine has been in continuous use above a predetermined speed. When the value of the accumulated weighted spark pulses has reached a predetermined level, a warning signal is provided to indicate the necessity of changing the engine lubricating oil. |
