Highway mileage should be about 22 mpg. The tank is around 18 gallons if memory serves me well. Very good cars.

Im getting about 28to to the gallon I think. I've been trying to average my gas as to how many miles I've driven how much gas I put in it. The gas gauge doesnt work in the car.


Here's what you do. Fill the tank to the top. Fill it so you can see the gas in the filler neck. Write down the mileage or set the tripodomerter to zero. Drive around like you normally do. After 200 miles or so fill up again. Just like before. Now divide the gallons into the miles. This will give you your MPH's.

I topped my tank off once. Then I drove 144 miles. 5.2 gallons filled the tank up After I drove that 144 miles and I was just trying to find out how big these tanks are in these cars. There must have been quite a bit of gas in here when I got it, I just wasn't sure how much cuz I didn't know how big the tank was thank you for your response
