The same formula but the boiling point went up. Sounds like fuzzy science to
me!

Folks,

Went looking for Castrol brake fluid and ran into two varieties: GTLMA and
GTLMA synthetic. Different labeling; same part number. An email to Castrol USA
got the following response:

"Castrol GTLMA now has a higher wet boiling point and the product label has
been changed. The product formula has not been changed; Castrol GTLMA has
always been a fully synthetic brake fluid. The wet boiling point has increased
from 3110F to 3290F (1550C to 1690C)."

So it sounds like you can mix the old and 'new' GTLMA. However, it's still
DOT3/DOT4. I wouldn't mix it with DOT5 synthetic.
