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: the Rocket III is designed to run on unleaded gasoline with a CLC or AKI octane rating (R+M)/2 of 89 or higher.
Caution! The use of leaded gasoline is illegal in some countries, states or territories and will invalidate the vehicle and emissions control warranties. Additionally, leaded gasoline will cause damage to emissions control components.
To help in meeting clean air standards, some areas of the U.S. use oxygenated gasoline to help reduce harmful emissions. The Rocket III 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 fuel is a mixture of 10% ethanol and 90% gasoline and is often described under the names 'gasohol1, 'ethanol enhanced', or 'contains ethanol'. This fuel may be used in Triumph motorcycles.
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.
