This going to greatly divide the camp . I originally done this purely for my own curiosity . This is one of my old anchor lamps it has a blacks of scotland badge . At this moment it is running on aspen 4 ,I have also had it previously running on E5 pump gas. I know very well the dangers that can happen, I would never had done this if I hadn't of completely stripped out all the old rubber pips and replaced with new viton pips . I also serviced the foot valve and nrv with a fresh spring to give a good seal I also readjusted the conducting rod so that it allowed for a better seal when the lamp was in off position . I also took the old packing out of the packing gland and used new graphite . I was only able to do this because I was confident with how I serviced the lamp and I would never suggest that anyone should just go and put petrol in a lamp designed for paraffin/ kerosene . Marten
It is running well As you are already well aware about the dangers of such attempts, I wouldn't want to elaborate those here. I have done so a fair number of times using pump gasoline. Not only on Petromax-styled lanterns but also on a Tilley X246-B and some kerosene stoves. Some behaved while there was at least one that turned out catastrophic with complete destruction of the lantern. It may run well for now. It might not be so after several light-ups. Those rubber pips (both the vaporizer's footvalve and the pump's NRV) are notorious for failing after prolonged exposure to gasoline. Even faster if you're not using Viton. On other occasions, even without apparent failure on the rubber materials, they might not always seat well in the NRVs. While Aspen 4 is far less damaging on rubbers than unleaded gasoline, it is still just as inflammable. You need to keep watch over it (from some distance) and keep away from the house. You don't want to risk property or other's lives as well... It is kind of thrilling(due to the inherent dangers) but someday we are going to get roasted if we continue to tempt it
@MYN your a lot braver than me running a Tilley on pump gas . Yes all the pips I cut myself from viton cord also a fresh filler cap gasket . I've used it probably 5 times now on this fuel and so far all is good although I shan't take it for granted that it will always be good . Your advice about not using near the house is understood , I hav'nt even had it alight in the shed always outside . @ColinG I was thinking about your post that you submitted a few weeks ago as I was typing this out . I do have a fire extinguisher at hand but hope to never use it . Marten
While Aspen 4 is unlikely to degrade Viton, unleaded gasoline(petrol) can certainly change its properties after prolonged immersion.
