I bought this car brand new and it gets the worse gas mileage I have ever seen. I never get better than 25 mpg highway. I bought this car with the Ford dealer telling how great it was on gas. That I would average 32 mpg. I complained to my dealer when I bought it and they said I was averaging 31. 7 mpg according to there computer. That is not true! then they said it needs a break in time of 5000 miles. I have 15000 miles on the car and I drive on the highway every day. Many other Focus owners have complained but Ford ignores us.
