I touched on why diesel engine are more efficient and it seems to come down to 2 big things. diesel have better thermal efficiency and diesel fuel in general has more energy density in then gasoline. overall this 3L Duramax was more efficient then every other full sized truck engine I have tested in the city, out in the country and on the highway. very impressive little engine. 00:00 - Intro 00:32 - EPA Ratings 01:02 - City Driving Economy 03:21 - Why are Diesel Engines Efficient? 04:38 - Country Driving Economy 06:23 - Highway Driving Economy 07:22 - Diesel Engine DARK SIDE 08:48 - Final Economy Results
