Hi, I'm John... I drive a 2012 Jetta Sportswagen TDI with the DSG. According to the trip computer I am just over 38mpg. My commute is from SF to the Palo Alto area, which is roughly 30 miles each way, mostly highway. I previously had a 2010 Golf TDI with the manual transmission. In that I was just around 41-42. The two cars (despite the name the JSW is really the Golf wagon, as it's sold everywhere else in the world except the US.) are pretty much the same, and I know the wagon is heavier but I was hoping the mpg drop would not be as much as it is. The engine at 70mph in the golf would be at 2000 rpm (roughly) and in the JSW it's at 2200 rpm. Any advice?
