Thanks. I have both the LE607 and the Amsoil 75w-110 ordered. Being in Ohio and this being my first winter with the S2000(don't know how much I'll drive it yet), I am going to put the Amsoil in first.
Better off using a 75-90W in the winter and 75-110 in the summer

This makes less sense as they would both have a low pour point (75W 
)
If pour point worries you, use the 75W-110 year round.
Don't forget that even in winter your diff will get warm / hot.
If you really have to drive your car on a regular basis at -11F, then the Amsoil 75W-110 would be a better choice.
(don't forget to use a 0W-xx (read 30) oil for the engine under those circumstances)
There is not a word in the manual about using anything but SAE 90 (old spec) for the diff, no outside temperature relation as there is for engine oil.
IMO the diff generates enough heat to not be worried about pour points of -11F.
A proper warm up is always necessary for mechnical things.

The kinematic viscosity of the Amsoil 75W-110 @ 100C is 20.4 cSt.
For LE-607 it's 20.96 cSt.
LE-607 would nowadays and according to the revised SAE-J306 spec be called a SAE 110.
At the time of writing the S2000 manual (1998?) the SAE J306 spec wasn't revised yet and the SAE 90 range was from 13.5 cSt to 24 cSt.
LE-607 and the Amsoil 75W-110 fit right in there
and are both OK to use in the S2000 diff, as per manual.
The Amsoil has a lower pour point though, the LE-607 has a lower Viscosity Index (IOW a bit more shear stable).
In any case, the Amsoil is IMO a much better choice then the "diff water" 75W-90 oils.
At +/- 15 cSt they also meet the old (and new) SAE 90 spec, that is true, barely though
LE-607 is still my favorite because of the excusive LE additive called ALMASOL.

otherwise it would seem that MOST people would be left in the dark about this and continue to use 90, instead of 110.
i'm sure this applies to a lot of consumers, not just s2k...
i mean, wouldn't honda corp, alert ALL honda dealer service centers about this?
i just find it suprising that we are left on our own without any type of notice that we need 110 for our diff, and not 90.

You mean the same Honda that doesn't supply their dealers with diff fluid? That Honda? At the time Honda first spec'd the straight SAE 90 oil, there wasn't any readily available. That Honda? No, I wouldn't expect any update.

but what about other manufacturers that use gear oil?
surely with the new specs, 90 being 110, etc, on and on...
others would be affected as well...bmw, mb, general auto store bulletins etc?
the only place i've heard of these new specs (90 being the new 110) is on s2ki.com
i would expect to have seen it elsewhere as well...
