Thank the author for providing us with such a good vehicle module, but the energy of the vehicle of this module is too single, there is only one choice for gasoline, and the synthesis method of gasoline is too cumbersome, and some raw materials cannot be obtained in the world of some module servers, such as various doomsday module services, which only brush zombies and various module monsters, Can you consider learning about the modern bio oil scheme, that is, all kinds of food are converted into vehicle usable oil through converters, including rotten meat from zombies.
In reality, there are new energy vehicles, especially electric vehicles, which have developed rapidly in recent years. Here, I suggest whether we can also find a second vehicle energy mode and imitate real electric vehicles, such as driving vehicles through Redstone or solar energy. In this way, we can protect the liver a little and don't have to collect energy raw materials,
This is my suggestion. If there is anything missing, please correct it.

The fuel process will be getting some improvements for the next big update. I've already implemented a config option for the next update where you can specify valid fluids to use as fuels.

Cool, can it be in 1.12.2?

Oh, thank you so much,
So when are you going to release the updated new module?
I can't wait to install it into my minecraft doomsday module server！

there are configurable fuels coming soon™ so the server can handle that themselves, soon™
