Note: the author of the article, the MG Car Club and the V8 Register and its officers and committee members take no position in recommending or not any particular type of brake fluid. If in doubt consult an MG specialist service provider. As with any other change from manufacturer's specification for your car, you should inform your insurance company if you change brake fluid from that originally specified.
