an oil change at a given temperature as detected by the oil temperature sensor 82 for example using this calculation the amount of oil evacuated or output from the engine can be calculated in step 314 the calculated evacuated oil amount is compared against a nominal value for the sump capacity if the calculated amount is greater than or less than the nominal value or tolerance range as determined in step 316 this information can be recorded as a fault in step 318 for further investigation and or maintenance in one embodiment the fault recorded in step 318 can be recorded electronically such as in association with operation of the electronic control module 78 and or an automatic deactivation device e g such as the flow switch described hereinabove for the hose assembly 102 for example in step 320 one or more notifications can be generated for an operator of the engine for example to advise the operator that a fault has been recorded by the system the notification can take the form of an audible signal a visual or text signal or some reasonable combination of such signals in other embodiments of the present methods and systems methods and systems are provided for performing one or more pre lubrication operations in connection with operation of.
