Gear oil or not gear oil that's the question?

[Ron Wainwright <ron_01056@yahoo.com>]

 While driving to my local parts guy for my religious 3k oil+filter
change(Mann filter by the way $3.00) i walked to go grab the usual
15W-50(synthetic $26.00) and came across this [Tri-synthetic 15W oil]
asked the guy what Tri meant told me it had more oil stuff in it(or
something) can anybody set me straight on that?
 (and am trying that TechRon the concentrate, they have a special on it
at the Pep-Boys it includes a gas treatment for $8.00 total) I'm going
to try it out as soon as i fix the problem that occurred to my car an
87 5ksq on the way to my local parts guy(I'm sure someone will agree
with me that I'm babbling on, my friend sure did) we talked about what
the problem might be for what seemed like hours[it was hours], o.k I'll
get to the meat of my latest question for the knowligable q-list. Whell
iv'e noticed some fluid(unknown) leaking under my differential(quattro)
whill driving id'e churn through the gears and noticed that my rpm's
would climb but the car was'nt, meaning that the car was'nt going as
fast as the rpm's were, felt like the tranny is slippin but my question
is no oil goes in the tranny rite? do i have a leak in the center
diff... What seals are down there, my brake warning light has been
comming on i need to replace the master Replaced my rotors and pads
2-months ago the warning lite came on re:blead the brakes rear first
then front then re:did the one rear felt good for a couple of days
(200miles) then felt like pressure dropped(ABS) then this any ideas as
to my next progect? Any help would be greatlly appreceated have the
bibles (Bentley manuals) Thanks in advance
 Ron
