Diesel prices used to just lag behind the going rate of gas. If gas was increasing, diesel would usually be cheaper for a period because consumption wasn't as high as regular gas, then diesel would be higher as gas went down. That doesn't seem to happen anymore though. Seems like diesel is always higher. I smell an agenda.
Perhaps I was fed a line of BS but I thought gas had more pollutants than diesel but people usually freaked cuz they could see the smoke from diesel? Perhaps that was before unleaded?
I wish we had more diesel cars in the US like Europe. Wouldn't cost that much to maintain if we had a lot of them here to support the mechanics. Love the gas mileage.
