[V8] middle age drip

[Kneale Brownson]

I'd be leery of older "bombs".  I think they suffer the loss of nitrogen
through the membrane sitting on a shelf just as they do in use.  I bought
one when I first got my 200q20v in the mid-1990s, but found I needed a new
master cylinder so I put the accumulator on a shelf.   I finally installed
it last year, but I only get about 15 pumps before it runs out of boost
(after shutting off the engine).  Should get 25-30.

Regarding the Mobil and Chevron hydraulic oils, neither was available
locally without special ordering and additional fees that ran the price of
a five-gallon pail into the $60 range, but I could get the Shell equivalent
for about $8 a gallon.  It's called Tellus 32T.  The "T" is important
because Shell also markets a Tellus 32 used in tractor hydraulics that
isn't as refined as the "T" version.   I have used plain Tellus 32 (which I
have a bunch of for tractors) in an Audi system and it worked fine except
it took a while to warm up.  The "T" version performs just like Pentosin
11S, as far as I could tell running it last winter in V8 #2,  which
undergoes a pump resealing and system flush back to Pentosin (since I have
a bunch of that too) while I'm doing the timing belt some time this summer.
