[DeTomaso] Redline NS or Mobil 1 LS?

[Pantdino]

You might want to go to bobistheoilguy.com and search the site and / or post the question to the oil engineers there.
Did the Royal Purple people recommend that for transaxles?
It is obviously thicker / more viscous than 75W-90 but I don't know how much so.

I like this description... I will be using this in the future. But just 
ast week I put Royal Purple 85W140 NS in my ZF.
Should I be draining and replacing it?

 As far as I'm concerned this post by Les Gray is the final word on this topic:

 OK guys.............here it goes. I (we) at Vehicle Performance Center
 here in Arizona where I work , have been using Redline 75-90 NS for the last 
5
 years in every ZF we service or ones which I rebuild. We have noted much 
onger
 synchronizer life and much better limited slip lock engagement with much less
 "slip" which equates to less heat build up.
         The reason is the LACK of the limited slip additive used to quiet down
 the LS noise/chatter which, as stated , many manufacturers use. This additive
 DOES NOT enhance limited slip performance , to the contrary .......it degrades
 the speed at which the limited slip goes to its maximum locking capabilities
 because it is extremely slippery stuff that will not allow the LS to groan or
 chatter as it engages ie: customers won't complain about odd noises when they
 turn their vehicle and the two rear wheels turn at different rates which 
egins
 to activate the limited slip.
         Now go one step further and guess what this ultra slippery goo does to
 your synchronizer rings ability to lock up on it's tower?????  Lets see . . . 

 slippery stuff - sync slips instead of grabbing - heat goes up - synchronizer
 ring  degrades more rapidly because of grater slippage and heat generated 
efore
 it finally grabs and locks up.

   The ZF synchronizers require a good bit of friction  as it is being applied 
y
 the synchronizer slider ring in order to "grab" the towers and lock up. Too
 slippery - longer time for the item to fully stop the gear and this will
 accelerate the speed of synchronizer and tower wear . . . . .  great for my
 business , bad for your wallet.
          I know that some will disagree with me and continue to follow the 
lock
 (and that's OK because different opinions are what makes us better and the
 dialog can lead to more information which can change minds ....even mine!!) 
ut
 folks, I spoke with the people at Redline on this subject at length years ago
 and will stand behind using this oil until I take my dying breath.

 If you don't care about how long your synchros last you can use something 
lse.

 Folks--
 eed final opinion since Redline products seem to be hard to find around here.
   hear good things about Redline NS but also about Mobil 1 LS---The difference
 etween NS and LS does concern me as I want a no hassle gear oil change in my 
F
 ith not having to add any additives.
 edline 75w-90 NS  or Mobil 1 LS?   4 Qts?
 Thanks
