[Healeys] Castrol GTLMA brake fluid

[Bob Haskell]

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.
