Bad gas mileage

Ok so I did some calculations and I found out my gas mileage.

I can run 160s on a tank and my tank is (I think 16g) so that's 10mpg that not good for a /6 is it.

you figuring out mileage properly?


divide miles by the gallons it took to fill..


plus like stated it you have taller tires on the car and didn't put the proper speedo gear in for the tire height then your showing less miles then you actually went.
