The gas gauge in our shop truck quit working over 10 years ago. As already recommended, we rely on the odometer. We fill it up when it gets close to 300 miles as we know it'll go at least 340-350 miles with a 26 gallon tank. This is a 2002 Silverado with over 315,000 miles on the original 5.3 engine and transmission.
Just read your odometer like a gas gauge. If you think about it, it's probably more accurate anyway. That is unless you're leaking or burning real rich, and if so, you would most likely already know you have other problems just by the smell.
