Transmission & Differential fluids: what do you all use ?

[f1anatic]

In Chicago, the club is in disarray. Not having met in over a year, the consensus among the 4 remaining members is non-existent over which gear oil to use in our group buy.

 

Of course this is for the greater forum good.

 

What fluids do you all use in your transmission ?

[rao]

None - they all have too many problems.

In for the results

[rao]

I drained everything, disassembled it, had it cryo-treated and then I use 1 bottle of z-max. No friction and infinite component life!

[Opie]

Motul 300v or Subaru Extra-S

I'm going to go with he's joking.

 

However at the same time, I would not put it past him to do it.

[gfxdave99]

However I am interested to find out what people use, outside of oil I'm still running factory fluids.

[Rika]

[Bbc84]

hmmm what to do.... so many choices

[bosco]

oops i thought it was an engine oil poll and voted for Mobile. carry on.

 

 

 

 

 

btw just use what Subaru recommends you guys sound like some other oil will make your car faster.

[MOMSWGN]

3 quarts of Redline lightweight shockproof and 1 quart Motul 300 as recommended by Andrewtech.

It's gearbox oil, can't make it faster, but sure makes it smoother

Amsoil Severe Gear 75w110 in the trans for ~8-10k now. I'm amazed at how much less I feel/hear the syncros whining....but i'm not happy enough yet. Gonna try switching to a shorter, weighted knob then move the shifter height up about 1" (i.e. Lose 1" on the knob but make it taller 1"). After that, if i'm not yet happy, switching to Extra-S.

I only see 75w90ns available for our cars. I have never heard of the light and heavy stuff.

 

Care to explain?
