Welcome to EM! I have a truck that gets really crappy gas mileage too, but it spends most of it's time playing in the mud instead of being my daily driver...........
Once I got a fuel efficient car, I started saving tons of money even when I had to do major repairs to it. The fuel savings were astronomical and over time has really saved me some cash..............
I used to have a Tempo! I loved that car! It had A/C and an automatic transmission. The car would get me about 22 MPG because I drove on the highway with it. If I kept the speeds at 55 MPH or less, it would get me 25 MPG. My friend had a manual Tempo that would get 43 MPG as he claimed.
I wish I never hit that damn deer with my Tempo.................
