FUEL SYSTEM/ENGINE MANAGEMENT 9
FUEL REQUIREMENTS
Fuel Requirements — all countries except USA
Outside America, all motorcycles are designed to be run
on 95 RON unleaded fuel.
Fuel Requirements — USA
In the United States of America where the octane rating
of fuel is measured in a different way, the following
information may be applied:
Triumph motorcycles are designed to run on unleaded
gasoline with a CLC or AKI octane rating (R+M)/2 of 89 or
higher. Federal regulations require that pumps
delivering unleaded gasoline are marked `UNLEADED'
and that the Cost of Living Council (CLC) or Anti-Knock
Index (AKI) octane rating is also displayed. These
ratings are an average of the Research Octane Number
(RON) and the Motor Octane Number (MON).
CAUTION: The use of leaded gasoline is
• illegal in some countries, states or
territories. Check local regulations before using
leaded gasoline.
Oxygenated Gasoline
To help in meeting clean air standards, some areas of the
U.S. use oxygenated gasoline to help reduce harmful
emissions. These gasolines are a blend of conventional
gasoline and another compound such as alcohol.
Triumph motorcycles will give best performance when
using unleaded gasoline. However, the following should
be used as a guide to the use of oxygenated fuels.
CAUTION: Because of the generally
• higher volatility of oxygenated fuels,
starting, engine response and fuel consumption
may be adversely affected by their use. Should
any of these difficulties be experienced, run the
motorcycle on normal unleaded gasoline.
Ethanol
Ethanol fuel is a mixture of 10% ethanol and 90%
gasoline and is often described under the names
`gasohol', `ethanol enhanced', or `contains ethanol'. This
fuel may be used in Triumph motorcycles.
Methanol
CAUTION: Fuels containing methanol
• should not be used in Triumph
motorcycles as damage to components in the fuel
system can be caused by contact with methanol.
MTBE (Methyl Tertiary Butyl Ether)
The use of gasolines containing up to 15% MTBE
( Methyl Tertiary Butyl Ether) is permitted in Triumph
motorcycles.
