Even I would never be so foolish as to use vegetable oil in an EV. I was merely pointing out that IF petroleum runs low, then I can still use vegetable oil for salads. Also, if modified properly, I can buy an old combustion-engine auto, and use Extra-Virgin to run that, as well. I expect the oil shortage to be very persistent, this time. As I did post in the Political Soapbox section, this morning.... It may be the overall and long-term strategy of the USA to cause the availability of petroleum products to dramatically take a nose dive. The reasons for this align with the policy of America, vis a vis China, to curtail the further expansion of China's military, and also its economic strength. This is why I say: This Oil Crisis these days, unlike the 1970s, has just begun. And, the Iran War is JUST STARTING, and Iran has only just begun to fight. I would be very worried if I had a combustion engine vehicle, at this point. Trump might decide to LAY WASTE to all of Iran's energy production capability...PDQ... So, you can see, now, what I am on about, I guess....
