1 point1. Regular fine, use a magnet to remove from the socket as you should take the rubber bit off your socket now. 2. I use ecp 10/40 and switch it every 5k. 3. big, possibly 32 but you don't want it too tight so you can do by hand if you're a man. 3. The sump plug is a standard 19. change your anti freeze, brake fluid and switch out the **** green pas fluid for dxII red stuff.
