If you are diligent about changing the brake fluid every 2 years as recommended you will probably be OK. It is just that every shop that works on English-British cars will tell you that you should use Castrol GTLMA. It might only be folklore but they have to service and stand behind their work so if that's what they recommend then that is good enough for me! Besides there is usually no difference in price, it just comes done to availability and convienience. Order some extra and put it on the shelf, it is good for any car except one with DOT 5 in it. NEVER mix the DOT'S. You will always wind up with the lower DOT's rating. BTW the DOT rating is given mainly for boiling point, it has nothing to do with compatability for seals. The story is the rubber Lucas-Girling uses for the seals is more compatable with the Castrol then the other brands. You also use the Castrol in the hydraulic clutch for the same reasons. Brake fluid is a lot cheaper than rebuilding and replacing the parts in the brake system!
