IsoPro™ Fuel

 

Product Description

This premium fuel, an 80/20 blend of isobutane and propane pioneered by MSR, boosts the performance of canister stoves.
It outperforms standard butane/propane mixtures and burns clean to reduce soot and clogs.

Features

* Improved Performance:
80/20 blend of isobutane and propane delivers superior performance throughout the life of the canister and in colder temperatures.
* Clean-Burning:
Optimal fuel blend results in reduced soot and clogs.
* Recyclable:
Canisters can be recycled. Consult your local recycling center for regulations.

Tips

How much fuel should I bring?
MSR recommends 4 oz. (114 ml) of liquid fuel per person per day for cooking or 8 oz. (237 ml) of liquid fuel per person per day for melting snow and cooking. An extremely cold trip, like skiing in Antarctica, may require as much as 15 oz. (444 ml) of liquid fuel per person per day.

How long will a canister of MSR IsoPro last?
In general one 8 oz. canister of MSR IsoPro fuel will be sufficient to boil water for two people over four days in summer. Wind, low temperatures and longer cooking times will increase fuel consumption.

Transporting Fuel
Carrying flammable fuel on passenger aircraft in carry-on or checked baggage is forbidden. Before transporting a MSR fuel bottle on an aircraft, safely empty all fuel from the bottle, wash inside with soapy water, rinse thoroughly, air dry, and stow uncapped.

Storing Fuel
Fuel degrades when it contacts air. Store your fuel in an airtight container, such as an MSR fuel bottle.


An Isobutane Seminar

Different fuels in a mixed fuel canister burn at different times over the life of that canister, beginning with high pressure propane and ending with lower pressure fuels like isobutane and n-butane. Canisters containing isobutane, like MSR's IsoPro will consistently perform at a higher level throughout the life of the canister than fuel mixtures containing n-butane. This is because isobutane has a higher vapor pressure than n-butane.
