ABSTRACT:
A method for determining the oil change interval for an internal combustion engine for driving a refrigerant compressor. The method includes the steps of sensing if the engine is being operated at high speed; incrementing the high speed counter during hours of high speed operation; sensing if the engine has been stopped; incrementing the counter for number of stops during the oil change interval; calculating the new oil change interval based on the current values in the high speed counter and the number of stops counter; and comparing the calculated new oil interval with the number of hours of service, and if the number of hours of service exceeds the new oil change interval, displaying a message indicating an oil change is needed.
