Returned from Canadian Grand Prix and needed to knock 1,200 miles of crud off the TDI. Gave the GTI a bath too while I was at it. TDI got 57.3 mpg and 51.3 mpg (actual) on the two road trip tanks. The second one included both border crossings (Canada was long and US was longer ) and Montreal traffic and had to turn on A/C due to bit of a heat wave that rolled in.
