GASOLINE

IMPORTANT: 

ALWAYS use gasoline that 

meets the following guidelines:

•

Clean, fresh gasoline.

•

A minimum of 87 octane/87 AKI (91 
RON). High altitude use may require a 
different octane. Consult your engine 
manual.

•

Gasoline with up to 10% ethanol 
(gasohol) or up to 10% MTBE (methyl 
tertiary butyl ether) is acceptable. 

•

Use of any gasoline other than those 
approved above will void the engine 
warranty. If the pumps are not marked 
for the content of alcohol or ethers, 
check ethanol and MTBE levels with 
the fuel supplier.

•

Do not modify the fuel system to use 
different fuels.

•

Never mix oil and gasoline.

NOTE: 

All gasoline is not the same. If the 

engine experiences starting or performance 
problems after using a new gasoline, switch 
to a different fuel provider or fuel brand.

IMPORTANT: 

Excessively oxygenated or 

reformulated fuels (fuels blended with 
alcohols or ethers) can damage the fuel 
system or cause performance problems. If 
any undesirable operating problems occur, 
use a gasoline with a lower percentage of 
alcohol or ether.

LUBRICATION 

Add a few drops of oil to the throttle control 
cable and wire to help keep it operating 
smoothly.
