I don&#x27;t get the math about diesel. American refineries produce 12 gallons of diesel and 19 gallons of gasoline on average[1] from a barrel of oil(42 gallons). I seem to remember that figure being lower and it looks like googles answer was 10 gallons at one point using the same site reference. I think that there was a push to get most cars off of gasoline and on to diesel before the VW scandal, and that diesel was going to save the world. I didn&#x27;t see how we were going to make that work when there is 50-80% less of the stuff per barrel of oil. I think in the real world the MPG gains are 25-35%[2]<p>I don&#x27;t know that EVs are the savior they&#x27;re pitched as, unless we can make battery tech and power generation cleaner. It looks like there is progress in that arena, so hopefully that continues. I think that we have demonstrably cleaned up gasoline cars while also increasing power output and MPG, and progress in that arena should continue as well. I think that diesel for passenger cars is a dead end, and it should be left to big rigs and heavy duty vehicles.<p>[1] <a href="http:&#x2F;&#x2F;www.eia.gov&#x2F;tools&#x2F;faqs&#x2F;faq.cfm?id=327&amp;t=9" rel="nofollow">http:&#x2F;&#x2F;www.eia.gov&#x2F;tools&#x2F;faqs&#x2F;faq.cfm?id=327&amp;t=9</a>
