In reply to leecamonline: OK today I did a test with the Lidl BBQ lighting fluid.
First I left the G jet on the MSR Dragonfly which is the one recommended for white gas and unleaded fuel just so I could do a comparison. The Lidl BBQ lighting fluid is actually quite difficult to light. The lighter I keep with my stove and only sparks which is fine to ignite unleaded petrol wouldn't light it. I had to find a lighter with a decent flame and even then you have to hold it there to get this stuff to light. It also seemed to take a long time to vapourise the fluid. When it did get going it burned hot and strong with a clean blue flame with no flare ups.
I switched to the K jet and again the stuff is quite difficult to light and again it took a little longer than usual to prime and vapourise the fluid but it was a bit faster/easier with the K jet. Again, once going, burned strong with a clean blue flame and no flare ups.
I don't know if this priming is usual with e.g. kerosene because I have only ever used unleaded petrol.
I'll run it like this and if I encounter any problems will post on here.
As it is harder to light it may be safer than unleaded petrol? However the fact that it doesn't vapourise easily means that you are possibly pouring a jet of fluid on to a hot stove which made it flare. Maybe it's just a case of getting used to the priming, amount of initial fuel to let into the cup and priming time.
Also, it may only be suitable for multi fuel stoves?
If ultimately it's cleaner, less toxic and cheaper than unleaded...
The choice is yours!
