ABSTRACT:
An engine oil condition sensor which measures oil temperature and the time the engine has been in operation since the last oil change. The sensor determines when the amount of "cold" engine operation exceeds a predetermined portion of the total engine operation in order to warn the operator to change engine operation patterns by providing more operation time at warmer temperatures. The sensor also accumulates the actual time the oil has been in the engine and the time the engine has been operated at elevated "hot" temperatures. Whenever any accumulation exceeds predetermined threshold levels, appropriate warnings are given to the operator.
