PRE-OPERATING PREPARATIONS

1. Recommended gasoline types

CAUTION
!
Use of improper gasoline can damage
your engine. Engine damage resulting
from the use of improper gasoline is
considered misuse of the engine, and
damage caused thereby will not be
covered under the limited warranty.
FUEL RATING
T O H AT S U e n g i n e s w i l l o p e r a t e
satisfactorily when using a major brand of
unleaded gasoline meeting the following
specifications:
USA and Canada - having a posted
pump Octane Rating of 87 (R +M)/2
minimum. Premium gasoline (92 [R+M]/2
Octane) is also acceptable. Do not use
leaded gasoline.
O u t s i d e U S A a n d C a n a d a - U s e
unleaded gasoline with declared octane
rating of 90 RON or over. Use of premium
gasoline of 98 RON is also allowed. Use
of name-brand leaded gasoline may be
allowed only if unleaded gasoline is not
available.
GASOLINES CONTAINING ALCOHOL
The fuel system components on your
TOHATSU engine will withstand up to
10% alcohol content in the gasoline.
But if the gasoline in your area contains
either methanol (methyl alcohol) or
ethanol (ethyl alcohol), you should be
aware of certain adverse effects that
can occur. These adverse effects are
more severe with methanol. Increasing
the percentage of alcohol in the fuel can
also worsen these adverse effects. Some
of these adverse effects are caused
PRE-OPERATING PREPARATIONS
because the alcohol in the gasoline can
absorb moisture from the air, resulting in
a separation of the water/alcohol from the
gasoline in the fuel tank.
These may cause increased:
 C orrosion of metal parts
●
 D eterioration of rubber or plastic
●
parts
 F uel permeation through rubber fuel
●
lines
 S tarting and operating difficulties
●
WARNING
!
Fuel leakage can cause fire or explosion,
potentially leading to severe injury or
loss of life. Every fuel system part should
be checked periodically, and especially
after long term storage, for fuel leak,
change of hardness of rubber, expansion
and/or corrosion of metals. In case any
indication of fuel leakage or degradation
of fuel part is found, replace relevant part
immediately before continuing operation.
If the use of gasoline containing
alcohol is inevitable, or presence of
alcohol is suspected in the gasoline,
it is recommended to add a filter that
has water separating capability, and
check the fuel system for leaks and
mechanical parts for corrosion and
abnormal wear more frequently.
And, in case any of such abnormality
is found, discontinue the use of such
gasoline and contact our dealer
immediately.
Damages resulting from the use of
gasolines that contain alcohol are not
covered under the limited warranty.
