Rook; "If Star Tron "digests" all of the ethanol"
It doesn't "digest" the ethanol, it prevents it from separating from the gas. According to Star Brite,
"The problem is all alcohol’s are hygroscopic. That means it likes water, and it
attracts and couples with moisture in the air, resulting in greater amounts of
water collecting in the fuel tank. Since water is heavier than gasoline, the water
and ethanol mix settles to the bottom. This is referred to as “phase separation”,
and eventually the water/ethanol phase is drawn into the fuel delivery system. If
there is no water separator in the line, the water goes into the injector/carburetor
and the engine does not run properly. In extreme cases, the engine will stop
running. For automobiles, this is not a common problem in that an entire tank of
fuel will most likely be used up within one week, well before a water/ethanol build
up takes place. Also, automobiles have smaller gas tanks, leaving less air space
for condensation to accumulate. Boats usually do not use up their fuel for many
weeks, if not months, and their large gas tanks, when left low in fuel, readily form
condensation. This presents a problem for most boaters.
An additional problem boaters will face is loss of octane, which is critical to an
engine's performance. Ethanol is over 100+ octane, and provides the fuel with
much of its octane rating. Once water reaches about a .5% level, it will phase
separate. With the ethanol drawn to the bottom along with the water, the fuel will
lose octane, and this can cause a loss of performance, including pinging and
engine knock, which can damage your engine. It also severely worsens fuel
economy and power.
There are other problems with E-10 fuel. Ethanol is a powerful solvent and
readily breaks up tars and organic sediment found in many marine fuel tanks.
The ethanol/water mix also makes a potent stripping agent for old varnish and
gum accumulated from years of gasoline sitting in the tank. These organic
contaminants, once loosened from tank walls, can plug filters and injectors
quickly, disabling your boat’s engine. In cold weather, the water/alcohol phase
can also freeze, turning into a syrupy mix that plugs filters."
