The 30 fluid ounce MSR Fuel Bottle is constructed in a single-piece impact-extruded aluminum process and painted with the signature MSR red. This fabrication technique creates a smooth surface, free of seams or welds, which yields exceptional strength and stability when pressurized.

- 591 mL / 20 fl oz.
- 887 mL / 30 fl oz.
All three sizes are designed to work with the entire line of MSR white gas (or liquid fuel) camp stoves. The threaded opening fits the pump while the tapered shoulders of the fuel bottle allow the fuel pick-up tube to properly contact the lowest point of the bottle. When placed horizontally during use it allows every last drop of fuel to be burned.
Both cap styles are fitted with an O-ring which sits perfectly within the beveled edge of the bottle’s lip, allowing for an air-tight seal. As with any O-ring it’s important to periodically check for cracking or signs of deterioration. Moreover, when closing the bottle make sure the thread and O-ring on the cap is free of any debris, especially if you’ve dropped it. This will ensure a leak-free bottle. Should your bottle leak, the first place to look is the cap.
While the MSR fuel bottle is designed for white gas and other liquid stove fuels it is very popular amongst motorcyclists as an emergency auxiliary fuel source. However, you shouldn’t be using the same bottle for multiple uses since automotive fuel can damage a stove.
With the largest bottle at $19.95 and even less for the smaller sizes it’s certainly a worthwhile purchase if you consider the sturdy construction and safety it affords while backpacking or camping with volatile fuels. Just don’t get too attached to the immaculate red paint job. Laying it down while in use will quickly scratch the shiny finish, but don’t fret, it doesn’t chip very easily.
