I don't know how old you are. Those under the age of 20 can learn. Your skills are not overwhelming, but you need to find a school or training center that focuses on gas maintenance. Nowadays, gas repair is not just a matter of changing parts. Many devices are controlled by computers. It is not easy to learn it well. On the one hand, it is theory, and more importantly, practice (internship).

You don't have to be engaged in gas repair industry to learn gas repair. This is a technology. After you get it, you can do other work. When there is really no work to do, you can take out a skill to support your family. Needless to say, the future car will be repaired like the current mobile phone. Knowing its working principle is also very convenient for you to use.

In short, there is no harm in learning more while you are young.

I studied gas maintenance, cook, and now I do logistics. Many times, I can use the technology I have learned, which not only won people's envy, but also proved my strength.
