the standard at highway fuel stations.
Currently, E10 (10% ethanol to 90%
gasoline) is common. There are advantages in cars but, in boats with fuel tanks
that have to be vented for safety reasons,
ethanol causes a number of significant
problems:
1) Ethanol is 'hygroscopic' - meaning
that it draws the moisture from the air
into the fuel. A litre of E10 gasoline
(with 10% ethanol) can hold approximately 2 teaspoons of water in suspension. When the gasoline reaches that

level of water absorption, phase separation occurs. The ethanol/water blend
separates from the gasoline and drops to
the bottom of the tank.
2) Ethanol is an octane booster - when
the pump says 87 Octane with 10%
ethanol, the ethanol contributes to that
octane rating. When phase separation
occurs, the ethanol/water blend separates and takes some of the octane along
with it. The gasoline that is left won't
fire properly in the engine.
3) Because of this, gasoline with ethanol
has a shelf-life of about 90 days. Any fuel

left in the tank at the end of the boating
season, may not have enough octane to
effectively burn at start-up in the spring.
This is also why 'premium' fuel is often
recommended. If the ethanol separates
from 91 octane fuel (taking with it some
of that octane), the hope is that there is
still enough octane rating remaining for
the fuel to fire in an engine designed to
run on 'regular' 87 octane.
4) Newer engines have been adapted to
manage E10 gasoline, but engines manufactured before 2005 have components
that can be damaged by E10 fuel.
