One drawback is that you tend to need more fuel than a shellite stove, and need to take more. Apparently if a small quantity of water is added, it reduces the blackening of the cook sets. Kerosene stoves are somewhat outdated and bulky . There are newer ones on the market for base campers that are quite good. Still a safer fuel than shellite, it spoils every thing when it leaks.
Shellite stoves are the best stoves to use.
Some have some type of preheating to quickly start the stove. They can be quite noisy and put out an intense heat that tends to burn every thing. They are very fuel efficient and good to take on extended walks. The fuel is volatile and care must be taken, especially lighting the stove. When lighting the stove, one must make sure that it is preheated properly and the fuel is turning to vapour before turning the fuel fully on .
