Replacing the engine oil and filter is definitely the first maintenance task you learn to do yourself, but be sure to dispose of the used oil properly. Before changing the oil, the video also shows the use of an additive for cleaning the oil circuit, which should be added before draining the oil while keeping the engine running for about 20 minutes; this is a detergent based on surfactants specifically designed to remove deposits accumulated between services: the author advises against this solution as the detachment of considerable deposits could clog the circuit rather than clean it; if you want to avoid the formation of deposits, perform maintenance earlier.

That said, locate the oil filter, which is just below the intake manifold, and unscrew the plastic cap, remove the old cartridge, and insert the new one, also replacing the O-rings. Then access the oil pan to unscrew the drain plug and drain the used oil; finally, fill the engine with new oil until reaching the maximum level.
