oilburner hello.
With the oil brake. If the pump the brakes, there is a green paint should be used only mineral oil the color green to avoid being attacked and bombit rubbers of the pump. only if you change the rubber to the DOT 4, otherwise even think to use other oils DOT. if it has no color signal oil being used is DOT 4 which is now universal for all vehicles except those with said signal. Generally most vehicles use this type of oil (mineral) are the Europeans, for these oils are not as aggressive and greener. No one more hug to all the guys.
