This small 12V pump works very well but you have to know the limits. For the warm engine oil change, it takes 3 minutes to extract per liter. The engine must not be too hot to not cause the softening of the suction pipe. Priming can be a bit long, you can shorten by first sucking a little oil from a bottle held above the pump. For the rest, the indications of the leaflet in French are sufficient. The build quality seems very good but the pump is quite noisy in use. Finally an article to recommend.
