I don't know firsthand, but I did google on "Solo Storm" + lighter and came up with this web page:

Sorry if this only tells you what you already know - I would assume that the lighter came with these instructions but I'll post it here anyway:

"Recommended Fuel:

The Lighter Company recommends using premium butane fuel, which is butane blended with propane. Premium butane fuel is sometimes characterized as "triple" or "double refined" butane.

Recommended brands include: Lava, Lucienne, King, Prometheus or Vector. These fuels are available at many outdoor specialty shops, sporting goods stores and tobacco shops.

The Lighter Company does NOT recommend using Clipper, Ronson, Scripto, Zippo or Sun butane fuels, as they may clog the butane feeding system in the Solo Storm Lighter and affect its overall performance."

I would assume that Coleman Butane fuel, even though it's not mentioned, is simply butane, not butane/propane, unless it specifically says otherwise.
