Well, the alky presumably was shipped in full tanks / barrels /
whatever, so we can hope it's undiluted.

But, it is _very_ difficult (it takes some expensive chemistry tricks) to
get all of the water distilled out of alcohol, in other words, stronger than
around 98% alcohol. Is that all the alky producers go for, or do they use
the expensive tricks to get the last two percentage points of water out of
the alky?

I doubt that they would go for the expensive tricks, since the alcohol
will absorb moisture out of the air and from the bottom of the fuel
tanks as soon as it contacts either. There is no point in trying for
higher purity.
