What fuel policy should I get?

Most rental car companies provide you a full tank policy. We advise bringing it back with a full tank of gas. If you want to save some money, it is best to fill up your tank before you return the car. Stations near airports or car rental places tend to have higher prices.

Unlimited miles is a good option if you plan to do a little sightseeing or visit a lot of clients all over O Fallon. You can drive wherever you want and not incur extra charges. Go over your policy to find out if there are mileage limitations.

Before you drive off

Before you begin on your O Fallon vacation, be sure you go over a few things prior to leaving the rental lot. You should:

  • Look over the car and make certain there is no dents or scrapes. Be sure to make note of it on the paperwork, or you may get charged for it
  • Inspect the trunk to see if the spare is inflated and the jack and lung wrench are there
  • Familiarize yourself with the car. Adjust the mirrors and seats to your liking, and figure out how to turn on the lights and wipers
  • Get comfortable working the navigation and entertainment. It's best to limit any unnecessary distractions when you are driving around a new city
