Container says only minimum wet boiling point is 311 degrees F...does not list dry...but to be a DOT 4 it must be a minimum of 446 degrees F.
From Ron's old post:
"Mercedes Benz recommends brake fluid changes every 24 months. I probably average 12 ~ 18 months unless a track day comes up then do a change just before and after.
It's easy to do and not only maintains boiling point performance (boiling fluid will not stop your car), but also prolongs brake line life as old fluid will corrode the lines from the inside out.
Castrol Synpower DOT 3/4 is a good cost effective fluid for street use. Castrol SRF expensive but nice insurance for the track, but max usage is limited to 18 months....
