I have also used my friend's oil stove, which is much more prosperous than the gas stove, and the later use cost is also cheaper than the gas stove. It's suitable for cooking, but there are two problems: 1 It's difficult to make gasoline, and now the fuel tank of the car is anti-theft, so I can't pump oil, unless I jump off the gun and continue to refuel, I can always pump some oil to the fuel filler, or I can remove the pipe of the engine compartment nozzle. Another way is to go to the police station to issue a certificate, and the gas station can take out gasoline (this seems very difficult, I have never operated it)!
All oil stoves need to be preheated, and black smoke will be emitted at the initial stage of preheating, and it will be blocked after long use. Even a stove without preheating will emit black smoke in the early stage, but the problem of black smoke in the early stage of preheating is easy to solve. I found that the problem of black smoke in the early stage of preheating can be solved by preheating without putting oil, pouring some alcohol and burning with alcohol. Blocking prevention is also simple. When the split gas stove is turned off, the oil bottle turns upside down, the oil suction pipe head can suck air, and the oil in the pipe can be washed away by the air pressure in the bottle, so that the fire can be naturally extinguished, and at the same time, the blockage can be avoided and the oil bottle can be decompressed.
Another way is to replace the oil stove with an oil nozzle, which can burn 95% concentration of medical alcohol. This kind of nozzle can burn alcohol by enlarging the aperture of gasoline nozzle. Alcohol is much easier to handle than gasoline, and it is sold in almost most pharmacies. However, due to the increase of nozzle aperture, the burning time of a bottle of alcohol is naturally shorter than that of a bottle of gasoline, but from then on, I bid farewell to complaining and plugging. However, sealing with alcohol will age faster than using gasoline. Just change it often.
