Hello my name is ***** ***** i will assist you. The engine if not a DFI or fuel injected engine does not have an on board computer that records the hours. If no with a 5 liter oil usage, it should have consumed around 250 - 300 liters of fuel which with approx average consumption of around 20 l /hr at 4000 rpm it should have not done more then 20 hrs of work.
If you require further assistance let me know.
