I guess (bringing it back to the OP) it reminds me a little of the "purring" sound a happy, well-fired Svea would make. Not as good, but Svea owners know what I mean.

I've heard from what I consider credible sources that the additives in automobile gaz are not good at all on camp stoves. The stove shouldn't give you any problem, but the fumes are (potentially?) very bad for your body. I've never heard of any problems with soothing on the pans using white gaz stoves before.

Where I live, major gaz stations sells something that translates to "environmental white gaz" for use in lawn movers and the like. The stuff is 95 octane "white gaz", but without additives. Much cheaper than coleman or MSR fuel.

Unleaded Gasoline

Our DualFuel™ appliances are made to accommodate automobile fuel. Coleman's modified valving even allows for differences between summer and winter blends. At 1/10 of the cost of propane, unleaded gas is the cheapest of all appliance fuels. And it's available everywhere, of course. In an emergency, you can siphon gas from the tank of your RV or car to use in a DualFuel lantern or stove. Although it's the most economical fuel to use, you'll extend the life of your appliance by using purer Coleman™ Fuel most of the time.
Main advantages: availability and low cost.

Doug,
I haven't tested it so I honestly don't know. It's pretty obvious to me after a week or two's use that the Superfuel burns cleaner though.

Agreed on the XGK. Nothing like it to draw some stares from the dedicated car campers at the trailheads.

I haven't personally used the Svea stove but growing up without electricity , we used Coleman gas lanterns every day and you definitely don't want to burn unleaded gas in those as it ruins the parts... so am assuming the same might work in any other white gas stove or lantern.

@7point82,

My testing gives the superfuel a slight (maybe 10%) advantage in the amount of cooking done, but I buy and use it because it is so much cleaner.

I don't know about my new XGK, but my old one went through many gallons of 80 octane avgas and quite a bit of 100 LL in AK. Lots easier to find when you were flying in (later I used a lot of Jet Fuel too). The avgas was dirty and required more cleaning but worked fine.

Used in my old SVEA, it clogged a lot.

The leaded gas was proscribed because the lead fumes were toxic. Unleaded is not so toxic, but I would still only use it outdoors.

The best,

Jerry
