Fueling (gas engine)

Gasoline is extremely flammable
and is explosive under certain
conditions.

Fuel Specifications

• Use automotive gasoline that has a pump
octane number of 86 or higher, or that has
a research octane number of 91 or higher.
Use of a lower octane gasoline can cause
persistent "pinging" or heavy "spark knock"
(a metallic rapping noise) which, if severe,
can lead to engine damage.
i
If "spark knock" or "pinging" occurs
at a steady engine speed under
normal load, change brands of
gasoline. If spark knock or pinging
persists, consult an authorized
dealer of the engine manufacturer.
Failure to do so is considered
misuse, and damage caused by
misuse is not covered by the engine
manufacturer's limited warranty.
Occasionally you may experience
light spark knock while operating
under heavy loads. This is no cause
for concern, it simply means your
engine is operating efficiently.
• Unleaded fuel produces fewer engine and
spark plug deposits and extends the life of
the exhaust system components.
• Never use stale or contaminated gasoline
or an oil/gasoline mixture. Avoid getting
dirt, dust, or water in the fuel tank.

Gasolines Containing Alcohol
If you decide to use a gasoline containing
alcohol (gasohol), be sure its octane rating is
at least as high as that recommended by the
engine manufacturer. There are two types of
"gasohol": one containing ethanol, and the
other containing methanol. Do not use gasohol
that contains more than 10% ethanol. Do not
use gasoline containing methanol (methyl or
wood alcohol) that does not also contain co-
solvents and corrosion inhibitors for methanol.
Never use gasoline containing more than
5% methanol, even if it has co-solvents and
corrosion inhibitors.
Fuel system damage or engine
i
performance problems resulting
from the use of fuels that contain
alcohol is not covered under the
warranty. The engine manufacturer
cannot endorse the use of fuels
containing methanol since evidence
of their suitability is incomplete at
this time.
Before buying gasoline from an
unfamiliar station, try to find out
if the gasoline contains alcohol.
If it does, confirm the type and
percentage of alcohol used. If you
notice any undesirable operating
characteristics while using a
gasoline that contains alcohol, or
one that you think contains alcohol,
switch to a gasoline that you know
does not contain alcohol.
