Ethanol-Blended Gasoline
Gasoline is distributed throughout the world that con-
tains ethanol. Ethanol-blended gasoline should not
cause engine problems if the fuel and fuel system are
properly maintained according to the instructions given
in this manual. The chapters covering
Maintenance
and
Storage
outline measures to prevent the ethanol
from damaging the fuel system.
Ethanol has several characteristics that may lead to
failures in marine fuel systems;
•
Ethanol acts as a solvent and will loosen contami-
nants or debris in the fuel system, which can then
clog filters, injectors and other parts.
•
Ethanol in gasoline attracts and holds water, which
can overload the fuel filter(s) and cause corrosion of
injectors, pumps, and other fuel system compo-
nents.
NOTICE!
Fuel system or engine damage caused by
water, foreign particles, sludge, or gum created by
ethanol fuel is not covered by warranty.
Volvo Penta Ethanol Fuel Treatment
(1)
, part number
22203959, should be used whenever fuel is added to
the boat, to maintain constant protection from corro-
sion and oxidation. Add the treatment according to the
instructions on the label. Also use the treatment for
offseason storage (winterization), as part of the fuel
treatment process. See
.
Volvo Penta gasoline engines are equipped with a
water separating fuel filter (see
water separating fuel filter between the fuel tank and
the engine is recommended. The filter must be
approved for gasoline inboard installations and be
installed in accordance with US Coast Guard regula-
tions and ABYC standards. The filter must be rated for
use with gasoline and have a minimum rating of 50
gallons (189 liters) per hour.
Water separating fuel filters should be checked fre-
quently for water and contaminants in accordance with
the
. Check and/or
replace the filter(s) as part of diagnosing engine per-
formance issues (see
). Carry spare filters and needed tools
and supplies to change filters when boating.
