To change the gear oil on a Piaggio Vespa GTS 300, you need to loosen the drain plug, which is located at the bottom of the transmission case on the left side of the scooter. Once the plug is removed, collect all the used oil in a container until it has completely drained out. At this point, you can top up through the other breather located at the top of the casing: once the necessary oil is inserted, check that everything is functioning correctly.
