A general question ; guesses count. In the past diesel ( aka , heater oil and furnace oil) was lower price than gasoline .In 1970 I paid near $ 0.15 / gal for home furnace oil when gasoline was $ 0.35 - I think it was $ 0.20 wholesale.no tax. Today diesel. etc is about 7% higher price than gasoline. I would have thought the relative costs would stay about the same . ( I worked for Amoco and am familiar with pipe stills, cat crackers. etc).
