Apologies to Dave for the following: please understand I am not flaming
you or criticizing you in any way.
I've often wondered about hydraulics truly lasting longer with DOT5
fluid. Using clutch hydraulics as an example, I've one Spitfire whose
clutch system was rebuilt over 15 years ago and not touched since, and an
early Herald saloon with at least 22 undisturbed years on the most recent
hydraulic clutch cylinder rebuild. Both cars are/were stored for extended
periods of time (over 20 years on the Herald; Spitfire, used as a very
occasional autocross car, is used once or twice a year at most and has
often been stored undisturbed 2-3 years at a time). Both cars used
whatever the best Castrol/Girling fluid was at the time. (OK, the brake
master cylinder in the Herald did go out during storage, but it hadn't
been rebuilt -- might even be the original 1960 cylinder!)
I've never used anything but Castrol-Girling fluid in any of my Triumphs,
and I've "run the gamut" from Crimson to Green to Amber to GT/LMA. I don't
dispute your success with DOT5; I've just never seen longevity as a reason
to use it. :-)
As always, YMMV!
