Gas gauge!!

Its been below freezing outside and my gas gauge stopped reading right, it still works, but it never goes below half of a tank. Is there a quick fix to this? I tried different gas, and some dry gas. Its been broken for a couple weeks.

You may have ice on the meter wand in your gas tank. Try adding a product called Heet in the red bottle into your gas tank. It is an anti-freeze/water absorber. Get it at any auto parts store/walmart. Franco

ill give it a try, thanks
