So if that was highway driving but a highway that is full of traffic and construction, that is really good. Just imagine if it all was smooth sailing! 50MPG? hmmmI just filled up today for the 1st tank. The computer said 38.5/mpg. But when I figure it went 340 miles on the odometer and it used 8 gallons, that comes out to 42.5. I did mostly hwy driving, but a lot of it is in traffic/construction like it always is in a minnesota summer. Not too bad, I'll be happy if it stays around there.
