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 may 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.
NOTICE:
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.
