Want to reduce the money you give to the corrupt state, reduce waste and save money? Make your own diesel.
People are complaining about fuel prices going up because of Operation Epstein Fury, but part of the reason prices are high is because of high taxes:
Biodiesel is easy to make from new or used vegetable oil and can be used instead of diesel in 21st century cars.
If you want to save a lot of money, ask restaurants for their old cooking oil cheap or for free. Biodiesel can also be made from animal fat, which is cheaper than vegetable oil, but there are fewer guides on the process.
Diesel can also be made from used motor oil if you have a centrifuge and a still for distillation: https://carobjective.com/how-to-make-diesel-fuel-from-used-motor-oil/

With this you could potentially separate crude oil into various components and use them for both gas and diesel cars, stoves, heating, oil lamps or sell them. Small sellers may be exempt from taxes depending on where you live.
For gasoline you could also try the ideas here, although they seem to be expensive or impractical for road users: https://www.wikihow.com/Make-Synthetic-Gasoline
