Bear in mind that the EPA requires better fuel mileage and emissions but has nothing to say about the pollution created by the manufacture of the components to bring newer vehicles into compliance and the manufacturing of vehicles to replace existing vehicles that with proper maintenance would be usable and efficient for thousands of more miles. Ethanol addition to fuel also reduces fuel mileage significantly and requires more trucking for the same quantity of product due to mixing logistics especially in remote areas let alone hicher maintenance costs for any vehicle using ethanol that wasn't specifically designed for it. Low sulphur diesel is another joke. Destroying injector pumps and other lubricated components and the process of removing sulphur and the addition and use and manufacture of additives for lubricity quality also has an effect on the quantity of pollution and efficiency of motor vehicles created. Over all it is my opinion that someone is making a lot of money on all this hogwash at the expense of hardworking people and the enviroment and would have you believe otherwise. I do remember when I was a auto mechanic in the late seventies and the egr valve was finally understood. The first thing you would do was disconnect the vacuum hose and retard the timing a tad.We new nothing of the damge to the catalytic converter at that time. Then came emissions testing. A car pre 1971 in good tune would actually pass the emissions test better than a catalyst engine. It became clear to me at that point that the emissions systems were only covering up the cars that weren't properly maintained. The only problem was NOX. Lean fuel mixtures would burn clean but would emit high nitrides of oxygen. Overall I think it is too little too late . Methane will be our enemy soon . Hang on to your military vehicles because pollution isn't going to be the problem soon. My opinion.great thread Harry
