I had no idea that the NA GP's get that kind of mileage, looks like most are at around 18 mpg....and I get and average of 19.7 in the city and 30 hwy with me romping on it at least 25% of the time. What gives? I would have thought at least 22-24 city on the NA's
Yes, but I read somewhere that it only makes about a 10% difference.
