"Just" 1-2mpg is a lot of fuel when you're in the teens or twenties.

I find that the gas saved driving 60 mph instead of 70 mph is quite large too!
I find using liters per 100 km is more understandable for comparing fuel economy. It's kinda weird to think about gallons used for 60 miles range, though.
My wife discovered that Costco's premium fuel is about 15 cents per liter (55 cents per US gallon) lower than the competition. So I'm going to try a few tanks of premium. If the gas costs 10% more and I get >10% better fuel economy ... the numbers work!
