Below is the link for gas prices in Texas. If you are traveling, please check the gas information for the town you are traveling to. Based on your travel, select the most likely place you will add gas in your rental vehicle.
Remember, you will have to turn in your rental vehicle with the same amount of gas as there was when you picked it up. Typically, it is full when you do. Any excess charges from the rental vehicle company for not following this process will result in those charges being assigned to the traveler. So remember to re-fill the tank before dropping the vehicle off.
