I didn't say it was solvency. Even if it was then I'd indict RedLine
before Hionda on the subject of testing and warnings... given your later
remarks about Honda MTF.

I'm not sure how a lubricant/fluid arrives at being characterized as
"ordinary-looking"... nor what the "analysis" actually examined.
Borate-esters would appear to be something I would not expect to find in
Honda MTF, given that they are currently being test marketed by the
additive mfrs - maybe something I'd want nothing to do with until that
testing is done. Obviously ZDDP works well and has for years and of
course, there's no catalytic converter in a gear box - in fact if ZDDP had
not been blacklisted by the auto mfrs we'd probably still be using it in
our engines and MoDTC would be an obscure chemical.

The Honda Australia site used to show the "Honda MTF" with the mention that
it was a 75W/80 API gear lubricant - not even sure if it'd be the same
stuff - but it was not rated as EP so I'd expect a modest (non-extreme)
friction modifier content.

Yes with Honda MTF, you *do* have to shift gently in low temps - not for
long though - but I expect that Honda is quite sure that it is not
incompatible with the metallurgy of their gearbox components.
