    I'm off to Sweden and Norway from Wales, UK, in 3 days time. I was going to run my Primus multifuel stove on unleaded petrol, syphoning it out of my petrol tank when needed. I've only used it a couple of times. It ran fine the first time and then got very smoky and clogged up the jet the second time. I put it down to my inexperience but my brother, a former RTW motorcyclist, said he would only run his multifuel stove on petrol in an emergency, prefering to use paraffin instead. What fuels are people using in multifuel stoves and why? Thanks :)

    I use the Primus Powerfuel or the Colemans in my Omnilite Ti.

    A 1 litre bottle will give you about 400 mins of burn time which gives you 28 mins per day over 2 weeks or 19 mins over 3 weeks. That should be plenty for most people assuming making a cup of tea or coffee in the morning (max 5 mins) and then boiling water for pasta or whatever in the evening.
    Yes the per litre cost is high vs petrol but over a 2 or 3 wk holiday, the price is insignificant and the benefits (NO CLOGGED JETS and less smell) for me more than offset the high price.

    Thanks. Yes, heaps of reading but only one review went into lots of detail about stoves and fuel. Although this review more-or-less said to avoid petrol, others reviewers didn't seem to have an issue with burning petrol with this stove, so I don't feel any the wiser!

    Thanks, but I don't have time to get those other fuels. I have petrol and I have paraffin. I haven't seen any reviews on using paraffin, so I'm still utterly undecided as to what to take. Hope to do some test burns tonight and see how I get on.

    No problems running mine with petrol. Have to use the cleaning magnet on occasion, but seems happy.

    I have a Primus Gravity MF 3281 stove, I've been using it since 2010. For multiday trips I usually use US unleaded gas, same as goes in my bikes, although the first bottle is generally ethanol free since that is what I normally keep in my fuel bottles at departue.

    Yes it is very sooty, but has always worked for me. After heavy uses, I take it apart (once at home) and clean all the soot from everything (baby wipes help in the field). Simple overnights I usually use the gaz bottles (if I have one handy) so maybe that has helped keep the innards flowing too. I was always worried about the thing sooting up and not working on a trip and bought a primus repair kit that I carry.......so of course I've never needed it.

    I use unleaded in the stove as my fuel bottles are "reserve" for my bikes as well.

    PS: make sure you are using the right jet for the fuel you are using.

    I have the same Primus stove. Make sure you’re using the right jet for petrol (marked with a “B” I think). You will need to clean the jet much more often than you would with white gas. Not sure whether paraffin is the same as white gas. You might be able to find the butane canisters in the Eurozone.

    Paraffin is kerosene.

    I've used motor petrol almost exclusively in my Primus multifuel Ti. In North America that's regular motor fuel with about 10% ethanol.

    The jet will start to clog up after 60 or 80 uses. I believe it's the shutdown procedure on that stove that causes clogging. Instead of turning off the flow of fuel, you upend the bottle so it feeds air to the burner until all the fuel in the line is gone. Pretty simple jet to clean, though and Primus provides the tools. Be sure to clean the parts just under the jet. A couple times I had a flake of soot in there that would float up and clog the jet after cleaning.

    admittedly I know nothing about camping stoves but why deal with the aforementioned problems with soot and cleaning etc when you could use propane instead? burns cleaner I think and bottles are easy to find. I would want a stove that real cooking could be done too, simmer and above...:y0!

    Our Omnilite TI ran with unleaded fuel in Iceland for two weeks with one little cleaning session (used for 3 persons, 3 l for tea and coffe in the morning and for the thermos, and a bigger meal with 30-45 minutes stove-time in the evening.

    The Sota Muka stove is designed to run on unleaded gasoline. Mine burns soot free on high octane.

    "Easy to find" depends on where you are. I like the convenience of propane stoves. I like the range and independence of petrol.

    The Primus Omnilite Ti can use propane too. Requires a jet swap.

    Wasn't that discontinued by Soto a few years ago? I don't think they've replaced it with anything comparable.

    Didn't know that. Mine is about 4 years old. A quick search shows a few still available from Japanese vendors. It is a good stove if a little pricey.

    Thank you all so much for your comments. I feel reassured that I can use unleaded. Last night I tried the stove again with petrol after a good cleaning. The wind was an issue to start with but after using the wind break (bit fiddly) I managed to get the stove running on a nice blue flame. Seems to take a long time to switch off (by turning bottle to Off and letting the remaining fuel in the pipe and air expel). Shortly to set off the 3.5 week trip to Scandinavia. Shame about the 40 mph winds I'll have to set off in!

    You'll soon learn when to turn the bottle over to complete cooking near when the fuel runs out. Or if you want to heat water with for a beverage, you can complete cooking, put on a pot of water, and soon after turn the bottle over so the water is more or less the right temp.
