And yes, you should always use a freshly opened bottle, then discard the<br>
remainder. Even their "low moisture activity" fluid still absorbs water<br>
right from the air, meaning it starts getting old the minute you crack the<br>
top.<br>

Sorry, no idea if the new Castrol is the same as the old Castrol. I'm a big<br>
believer in DOT 5 (which, among other advantages, doesn't suck water out of<br>
the air and hence keeps forever in an opened bottle).<br>
