Fuel And Oil; Gasoline - Suzuki DF150 Owner's Manual

FUEL AND OIL

GASOLINE

Suzuki highly recommends that you use alco-
hol-free unleaded gasoline whenever possible,
with a minimum pump octane rating of 87
((R+M)/2 method). In some areas, the only
fuels that are available are oxygenated fuels.
Oxygenated fuels which meet the minimum
octane requirement and the requirements
described below may be used in your outboard
motor without jeopardizing the New Outboard
Motor Limited Warranty.
NOTICE
Use of leaded gasoline can cause engine
damage. Use of improper or poor quality
fuel can affect performance and may
damage your motor and fuel system.
Use only unleaded gasoline. Do not use
fuel having lower than the recommended
octane, or fuel that may be stale or con-
taminated by dirt/water etc.
NOTE:
Oxygenated fuels are fuels which contain oxy-
gen-carrying additives such as MTBE or alco-
hol.
Suzuki recommends that you install a water-
separating fuel filter assembly between your
boat's fuel tank(s) and outboard motor(s). Fuel
filtration systems of this type will help prevent
water that may be present in your boat's fuel
tank(s) from contaminating your motor's elec-
tronic fuel injection system. Water contamina-
tion can cause poor engine performance and
can also cause damage to the electronic fuel
injection system components.
Your Authorized Suzuki Marine Dealer can pro-
vide you advice about water-separating fuel fil-
ter systems and installation.

Gasoline Containing MTBE
Unleaded gasoline containing MTBE (Methyl
Tertiary Butyl Ether) may be used in your out-
board motor if the MTBE content is not greater
than 15%. This oxygenated fuel does not con-
tain alcohol.
Gasoline/Ethanol Blends
Blends of unleaded gasoline and ethanol (grain
alcohol), also known as gasohol, may be used
in your outboard motor if the ethanol content is
not greater than 10%.
Gasoline/Methanol Blends
Avoid using blends of unleaded gasoline and
methanol (wood alcohol) whenever possible.
DO NOT USE fuels containing more than 5%
methanol under any circumstances. Fuel sys-
tem damage or outboard motor performance
problems resulting from the use of such fuels
are not the responsibility of Suzuki and may not
be covered under the New Outboard Motor Lim-
ited Warranty.
Fuel containing 5% or less methanol may be
suitable for use in your outboard motor if they
contain cosolvents and corrosion inhibitors.
Fuel Pump Labeling
In some states, pumps that dispense oxygen-
ated fuels are required to be labeled for the type
and percentage of oxygenate, and whether
important additives are present. Such labels
may provide enough information for you to
determine if a particular blend of fuel meets the
requirements listed above. In other states,
pumps may not be clearly labeled as to the con-
tent or type of oxygenate and additives. If you
are not sure that the fuel you intend to use
meets these requirements, check with the ser-
vice station operator or the fuel suppliers.
NOTE:
• Be sure that any oxygenated fuel blend you
use has octane ratings of at least 87 pump
octane ((R+M)/2 method).
• If you are not satisfied with the driveability or
fuel economy of your outboard motor when
you are using a gasoline/alcohol blend, you
should switch back to unleaded gasoline con-
taining no alcohol.
