Many are complaining about fuel prices going up because of the war on Iran, but prices were already high because of high taxes:

You can avoid these taxes by making your own diesel at home, potentially saving money while reducing waste and being less dependent on geopolitical affairs.

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/

How to make a simple still from a pressure cooker, copper tubing and bucket: https://www.instructables.com/How-to-make-a-still/

Making a fractional distillation column isn’t that much harder: https://www.instructables.com/Build-a-Lab-Quality-Distillation-Apparatus/

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

    Like I said, follow the instructions. That includes removing impurities if you’re working with used cooking oil. If it’s unused then that simplifies things.

    Doing it at scale may not be economical because of taxes as well as the fact you either need to buy expensive vegetable oil or collect large amounts of used oil from disparate places. For personal use the taxes are avoided and you may be able to get sufficient used oil from a couple of restaurants or neighbors.

      You’re speaking with confidence you can’t have, as you’re using wording that makes it clear you’ve no actual experience.

        StopTech doesn’t understand that when biodiesel is manufactured properly, the hydrocarbon-chain-lengths are limited to the appropriate-for-that-specific-type-of-fuel lengths-range.

        Used cooking-oil is chemically a mess & will void the warranties on engines, in its 1st use.

        NO engine-manufacturer ought have to warranty ANY engine that has had random “fuel” burned in it.

        That it’ll “work”, for awhile … while wrecking sensors, gumming/laquering/carbonizing all kinds of things in the engine, enforcing that the engine-itself won’t be able to perform properly soon … that is a wartime-only “solution”, in my eyes.

        MentalEdge@sopuli.xyz you are right, on this one, I hope readers of this page see.

        I’m only speaking from what I have read. Apparently it is perfectly fine to run engines on biodiesel from using cooking oil or diesel from used motor oil as long as you have a good filtering process using a centrifuge. And I’m not saying that everyone will be able to save or make money this way, just that it’s something one could explore and at least limit the amount of tax they give to a corrupt government.
