The first car I got was a 1989 Toyota Corolla. I don't know how many mpg it got but I refueled it every couple of weeks for $16 for a full tank.
Now I got a 99 honda civic. I refuel it every 2 weeks for $20, the lowest mpg I got was 21mpg and the highest was 44mpg.
I hope this one lasts a couple of more years so I can get an electric car, no gas, less maintenance, and I would do my part on getting off the oil dependence.
