Wow, 13 mpg sounds very low. I am pretty sure that I get 20 to 25 mpg. Even when all I do is drive the very short trips to work at low speed, I get about 20 mpg. When I drive the highway on a trip for vacation, I always get 25 mpg. I only have 70K miles, but it seems like there must be something affecting your mileage.

I think it might be like always going back to that same bad relationship with an ex girlfriend.
You feel you love them too much, or you are just too stupid to know any better.
