Abstract
A method for providing an oil change indication to an operator of an internal combustion engine having an exhaust-after-treatment system requiring regeneration, The method includes detecting regeneration events performed on the exhaust-after-treatment system; detecting oil temperature events each time unit an oil temperature is over a threshold value, and providing the oil change indication to the operator as a function of the detected regeneration events and the detected oil temperature events.
