Thx to Jason for sending me the following link about my gasoline tips post-
While not totally disputing the tips as in some other Internet rumour emails, the above link does make you think how much you will actually save for the trouble. Maybe not accelerating so fast and other bad driving habits can save you more. (You can buy a Prius too).
I was looking at one of those Smart cars that they just started selling here in the U.S. I was surprised that they required premium gas.
