Almost two years ago I had to replace a part on my truck (4 cyl S-10). My mechanic couldnt find an exact and ended up putting a heavy duty part on and told me my mileage would drop some. I lost 3mpg, dropping it down to 22 instead of 25.

So this year I decided to reduce my speed to 50-55 hwy, 60-65 freeway (which I dont travel much now that I dont work in the twin cities). By reducing to 50-55 I have gained back what I lost to 25 mpg highway.
