That is an excellent first hypothesis - expensive gasoline diluted
with cheap water plus solvent or surfactant compatibilizer. Do a
routine Karl-Fisher titration on new stock received; look for OH
stretch in a thin film IR, see how much it solubilizes a water-soluble
ionic like sodium fluoresceine. Sucking humidity won't give you that
kind of water volume/time.

Politically corrupt Enviro-whiner gasohol must be compounded at point
of sale. It is vigorously hygroscopic and viciously corrosive
thereafter, plus phase separation with changing composition and
temperature. It also has lower energy content/volume - and gasoline
is pumped by the gallon.

Enviro-whinerism - expensive, shoddy, deadly.

Adding docusate sodium (sodium dioctyl sulfosuccinate) plus physical
dispersion will re-emulsify the water into the gasoline. This would
be a wrong thing to do.
