Well, it's less than $4 per gallon in Russia; one has to wonder which country is being sanctioned
Gas today typically contains 10% bioethanol, and that number is expected to increase in the future. The goal is to burn less fossil fuel, which is a good thing.
Problem is: bioethanol often comes from sugar beet or cane, we literally run our cars on processed food. For Diesel, it is typically mixed with vegetable oil, again, burning food.
There is hope that one day, we will be able to make biofuel in a way that don't compete with food production, but we are not there yet. There are some successful experiments, but nothing at scale.
The sanctions on Russia are only just getting started.
With new car sales in Russia down over 80% in May, the pressure will increase the prices of used cars.
One way or another, Russians are paying for the barbarity of their countrymen, and the price they pay will only continue to get higher.
