That was a good article, but!!!!! "(To date, they have declined to scrap money-making gasoline production units worth many billions of dollars and replace them with even more expensive diesel hardware.)" This statement refering to "expensive diesel hardware",is an out-right lie!!!!!!!!!! The person he got this information from was feeding him some big stories and or exadurations! I know several people who work at refineries, including my father, the refining techniques are faster and easier than that of gasoline. This includes lowering the sulfur emissions. My dad pointed this out to me just last week. He showed me from the road the diesel refining area. It is new and much smaller than the gasoling facilities! You have to WATCH your sources!!!!!!!! Don't believe half of these articles, they don't want you to know the truth!!!!!!!!!!
