Fuel Recommendation; Oxygenated Fuels - Honda HS828 Owner's Manual

Fuel Recommendation
Use gasoline with a pump octane rating of 86 or higher.
We recommend unleaded fuel because it produces fewer engine and spark
plug deposits and extends exhaust system life.
Never use stale or contaminated gasoline or an oil/gasoline mixture. Avoid
getting dirt or water in the fuel tank.
Occasionally you may hear light "spark knock" or "pinging" (metallic rap-
ping noise) while operating under heavy loads. This is no cause for
concern.
If spark knock or pinging occurs at a steady engine speed, under normal
load, change brands of gasoline. If spark knock or pinging persists, see an
authorized Honda snowblower dealer.
II Ru
nning the engine with persistent spark knock or pinging can
cause engine damage.
Running the engine with persistent spark knock or pinging is misuse, and
the Distributor's Limited Warranty does not cover parts damaged by
misuse.
Oxygenated Fuels
Some conventional gasolines are being blended with alcohol or an ether
compound to increase the gasoline's octane. These gasolines are collec-
tively referred to as oxygenated fuels. Some areas of the United States
and Canada use oxygenated fuels to help meet clean air standards.
If you use an oxygenated fuel, be sure its pump octane rating is 86 or
higher.
ETHANOL (ethly or grain alcohol)
Gasoline containing more than 10% ethanol by volume may cause
starting and/or performance problems. Gasoline containing ethanol
may be marketed under the name "Gasohol".
METHANOL (methyl or wood alcohol)
Gasoline containing methanol must contain cosolvents and corrosion
inhibitors to protect the fuel system. Gasoline containing more than
5% methanol by volume may cause starting and/or performance pro-
blems and may damage metal, rubber, and plastic parts of your fuel
system.
MTBE (methyl tertiary butyl ether)
You may use gasoline containing up to 15% MTBE by volume.
Before using an oxygenated fuel, try to confirm the fuel's contents. Some
states (provinces in Canada) require this information to be posted on the
pump.
If you notice any undesirable operating symptoms, switch to a conven-
tional unleaded gasoline. Fuel system damage or performance problems
resulting from the use of an oxygenated fuel are not the responsibility of
Honda and are not covered under warranty.
(NOTlCEI 0
xygenated fuels can damage paint and plastic. Be careful not
to spill fuel when filling your fuel tank. Damage caused by spilled fuel is
not covered under warranty.
