The gasohol also acts as an oxygenate, getting more O2 into the combustion
process to carbon monoxide emissions during the warm up cycle. If we have
more O2 in the combustion process due to it being absorbed in the fuel then
the O2 sensor system will enrichen the mixture accordingly. Thus an
additional slight increase in fuel consumption and maybe even more power,
maybe. The major downside for older vehicles and many small/marine engines
is compatibility with some fuel system parts and the increase in moisture
absorption.

To quantify the question, one reference says 111,800 BTU per US gallon for
reformulated E10, vs 114,000 BTUs per US gallon for regular gasoline - a
1.9% reduction in energy content. (Other factors do come into play,
including the different motor octane and research octane numbers of the E10,
and the slightly lower viscosity, which may cause certain fuel injection
systems to inject more E10 per cycle, lowering fuel mileage.)
I had an '83 VW Rabbit, CIS injection, that took a 10% mileage hit running
on a late '80s version of E10 - but had measurably faster acceleration in
gear, and much better hill climbing ability on the E10. Every engine will
vary in its reactions.
Perhaps the lack of fuel pump noise is due to the E10 picking up some of the
water (or rust) in your fuel tank and carrying it to the pump, which the
regular gas is not doing. Do you have a fuel filter between your tank and
pump?
