The gas hand in my car is never right, When it is empty it shows half a tank left till empty. it took me a while to notice my car was just running out of gas and not a serious problem. what is this problem called and how much will it cost to get it fixed? Can i get this fixed somewhere besides the dealership. My car has also been saying low brake fluid, is this an easy process i can have done when i get my gas level checked here in Stillwater as well?
