10 States With the Absolute Highest Gas Prices
If you’re planning to visit one of these beautiful states – budget a little extra for gas.

Why Do Gas Prices Fluctuate?

The price of gasoline fluctuates depending on crude oil prices and how much gasoline is available at any given time to meet the demand of the people. When the demand is high, it can put a lot of pressure on whatever is available, which drives up prices. These costs you pay to fuel your vehicle cover several prices like the process of refining crude oil once it’s acquired. Sometimes geopolitical events have an impact on the per-gallon dollar amount you pay as well.

Sometimes these changes in cost are minimal and on other occasions, when you look at state-to-state comparisons, you realize the difference is quite notable. These differences across states occur not just because of supply chains but also because the cost to do business in each state varies. While some states have state taxes, others don’t. Some states house oil refineries and pipelines while others are further away from the supply.

Proximity to oil refineries and pipelines plays a role in the cost of gasoline from state to state.
