FUEL INFORMATION
The WhisperLite™ Internationale stove burns a variety of fuels by using two interchangeable Jets.
1.
The UG Jet is used for White Gas and Unleaded Auto Gas. This Jet is preinstalled in your stove.
2.
The UK Jet is for Kerosene. This Jet is included in the parts kit with your stove.
To exchange Jets, see “Cleaning the Jet and Fuel Line.”
Use MSR
®
SuperFuel™ (White Gas) for optimal performance. It is the highest quality fuel available for your stove.
Do not use leaded fuels. Fuels other than MSR SuperFuel white gas lead to rapid stove clogging and require
more frequent Jet and Fuel Line cleanings. Also, the use of Unleaded Auto Gas may shorten stove lifespan. Use
the fuels chart below to help you find your fuel when traveling internationally.
Visit www.msrgear.com for more information on international fuel names and safe stove transportation.
