Castrol LMA says it exceeds DOT 3 and 4. It is also totally compatible with
the current DOT 3 and 4. Each of these, including the 5.1 are all totally
compatible and miscible with each other.
They each will differ slightly in their dry and wet boiling temps.
DON'T confuse the above with DOT 5, which is the silicone fluid. It is at
least compatible with all the others, but is NOT miscible with ANY
otherbrake fluid.
