With all the new enviromental control systems on todays diesels, what is everyones opinion about them?
You are correct, stop and think about the heat from the extra fuel burnt, it is a different type of pollution but it is still pollution.you sacrifice 10-30% in fuel economy and increases engine wear. I may be a lil crazy, but I would think overall less pollutants would come out a vehicle getting 20mpg as opposed to an identical one getting 16mpg in the long run by the reduced consumption of fuel. Over 100,000 miles @ 20mpg is 5000 gallons. Identical vehicle at 16mpg over 100,000miles uses 6250 gallons. Thats an additional 1250gallons of diesel fuel burnt. How can that be better for the enviroment?
