Castrol LMA Brake Fluid

Anyone used the Castrol LMA fluid in their van? LMA= low moisture activity. It's supposed to absorb less moisture from the air. Min wet boiling point= 311F, Min dry boiling pt= 509F. Close to the values (550F) for the Motorcraft fluid specified and at nearly 1/4 the cost. I put in a 500f fluid last year, but only bled. I'd like to do a full fluid replacement this spring with a vaccum unit (the one mentioned in various threads from Harbor Freight). Just suck out all the old and fill with the new. What think you all?

what dot rating is it?

Says it exceeds DOT 3 and 4 requirements. Whatever that means. Our vans specify DOT 3 (I think), so it should do the job. I just know that it has much higher boiling points than anything available in my area.

I'm not brake fluid authority, I'm sure others will chime in but I know that different dot ratings can't be mixed. I have heard that when changing the system over completely it can be done but I'd wonder about fully flushing a system and switching without removal of lines. I'd do further research if I were you.
