Why gas prices vary by state

Have you ever wondered why gas costs so much more in California than in Texas? Gas prices aren’t just about the cost of crude oil. State taxes, refinery locations, environmental regulations, and demand all play a role. For example, West Coast states often have higher prices due to stricter fuel standards and fewer refineries. In contrast, states like Texas benefit from nearby refineries and lower fuel taxes.

Use this tool to find the cheapest gas near you

The best way to save on fuel is by comparing prices in your area. Use the official FuelEconomy.gov price finder. It lets you search by zip code and shows real-time prices at local stations. You might be surprised how much you can save by driving just one mile further.

Tips to save money on gas

  • Use gas rewards apps: Apps like GasBuddy, Upside, and even grocery store rewards can offer cash back or discounts.
  • Drive efficiently: Avoid sudden stops and starts, and don’t idle too long.
  • Maintain your car: Keep tires inflated and get regular oil changes to boost fuel efficiency.
  • Plan smart routes: Combine errands to reduce miles driven.
  • Go easy on the AC: Using air conditioning constantly can lower your miles per gallon.

How taxes affect gas prices

Each state adds its own tax on top of the federal gas tax (18.4 cents per gallon). States like Pennsylvania and California have the highest fuel taxes, often adding over 50 cents per gallon. These taxes fund road repairs and infrastructure, but they also raise your fuel bill. Knowing your state’s fuel tax can help you understand why you’re paying more—or less—at the pump.
