Another extremely great product. All Motul synthetics are double ester GRP V bases. The best of the best.

This 75w-140 works fine in Bravo's as it is a double ester that remains at 75W unless it's heated up to extreme temps. Very unusual feaures in this product.

...ever see Amsoil products doing as good or worse in thier "studies"?..
Amsoil Severe Gear and Torco products are comparible I think as the Torco synthetic gear lubes are GL-6 rated.
I ran M-1 syn gear lube and it is also really good as is Royal Purple's gearlube.
Just an fyi...Merc HP gearlube is not be be discounted....it works well...however...I didn't see as much on the magnet when I went over to a syn.

All I can say about "doing as good or worse in their studies?" is if the test was biased, they would be number 1 in every category. Also, I would like to see another company compare themselves to AMSOIL. You never see Mobil compare themselves to them. They always compare themselves against the Pennzoils, Castrols and whatnot. Royal Purple is garbage. Its not half the product it used to be ten years ago or so. Motul is typically a really good product, however, for at least twice the cost, its not that much better.

I've been running Royal Purple gear lube because of recommendations from people setting up drives on this forum. Is it really garbage? And, if so compare directly to amsoil or Mobil 1.

I was particularly interested to see that the Red Line 75W-90 was quite a bit better than the Amsoil Severe Gear Lube in the ASTM D-3233 Falex Extreme Pressure Test and that was not even the Red Line Shock Proof Gear Lube which according to Red Line's ASTM D-2596 heavy load test data has roughly half the wear of the basic Red Line. The Torco SGO Synthetic results on the ASTM-3233 test was also better than the Amsoil.
Of the ASTM test protcols that Amsoil used, which (if any) would you consider useful and which would you not in evaluating a drive oil's merits?

The most prevelant gear lubr rating currently is GL-5.
The GL-6 rating has been out of vouge for maybe 20 years or so.

Double ester....a mix of two different esters?

All multi viscosity oils act like the lower number(only in cold weather tests, the "W" means winter) and will THIN to a viscosity which equates to the higher number at 210*F.
210* is the most extreme temp the API tests and qualifies oil at.

The Motul 300v series that you state are great are ALL 'catalytic converter' recommended, including there motor cycle oil, does that mean there is a low ZDDP content?
