To change the oil in a Troy-Bilt pressure washer, first ensure the engine is off and cool. Locate the oil fill cap, typically found on the side of the engine, and remove it. Drain the old oil by tipping the machine slightly or using a siphon for easier removal, then refill with fresh oil according to the manufacturer's specifications. Finally, replace the oil fill cap securely.
