Anyone try this Amsoil 75w-110 in the rear diff? Any other thoughts on it?

Looks like some thick stuff. May not be a bad idea.

 

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.

 

I think i understood maybe 2 things in that post.

 

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.

 

FYI,,, LE607 is gone. almasol is gone. spoke with the guys at LE and got the lowdown.

the replacement for it, is LE1605. it has duolec now. supposed to be sweet. pretty much same stuff, just a tad of pixie dust sprinkled in. it is a 110 also. so we are good to go. lates

 

pay attention peeps. ^^ assuming this is fact, we need to put a note in the sticky.

 

No More LE-607...





As long as it's purple.
That's all I care about

Where is RoadRage when you need him?

 

Interesting....subscribing to this.

 

I still have 2 quarts of LE607. Any bidders???
