What's the average US monthly gas bill?
Around $130–$160 for a typical commuter driving 1,000–1,200 miles per month at ~28 MPG.
How do I lower my gas bill?
Drive a higher-MPG vehicle, combine errands, check tire pressure, and use apps like GasBuddy to find the cheapest stations.
Does premium fuel save money?
Only in cars that require it. Putting premium in a regular-fuel car wastes money with no MPG benefit.
