Finally decided on buying a Quickjack. So I am planning on doing some basic maintenance on the car in the future, starting with oil change. From my research, draining the reservoir can become messy so I was looking into the Stahlubus oil drain valve (http://www.stahlbus.com/products/en/oil-drain-valve/index.php), more specifically their extension system (https://www.stahlbus-us.com/oil-drain-valve/accesssories-oil-drain-valve/operation-tool-for-stahlbus-oil-drain-valve-alu-natur.html). They are similar to the Fumoto valve in concept but much lower profile and I think they are better designed. I am considering use the valve for both the oil pan and the reservoir, unless someone has something negative to say about them, or at least for the reservoir to avoid splashing oil on to parking brake cable or electrical connections etc. 1) Will appreciate any opinion, comment, words of wisdom you have to offer. 2) Can someone please share with me the thread size of both plugs so I can order the correct parts. Thank you.
