FWIW, I've had DoT5 in my BJ8 for nearly 30 years with no issues,
including bleeding. My dad put Lockheed DoT4 in our BN2--a complete
new system--and it gelled when the car sat for a couple years. I
tried Petrosin--BMW's bespoke brand--and several seals failed, with
a crystalline residue, after just a few years. There was a thread on
the BCF a while back on owners having failures with DoT3/4. Tom
Monaco strongly recommends Castrol DoT4 'synthetic*' but, so far, I
haven't been able to get a good pedal with it (I'm not blaming the
fluid). Note DoT5 is not hygroscopic, but does need to be flushed
occasionally since any water will pool and settle in low points.<br>
<br>
* Some brands of BF are now calling their product 'synthetic,' which
is odd since, AFAIK, no BF is made from naturally occurring
compounds. I suspect this is marketing, to ride on the popularity of
synthetic motor oil.<br>

<div>The BN2 is at the point where it
is time to fill and bleed the new
brake system. Now comes the time to
decide whether to go with DOT 3/4
brake fluid or try silicone. Any
recommendations, advice or warnings
