The FTC enforces several rules for labeling and advertising fuels, oils, and cars. The FTC also brings law enforcement actions against marketers that make false or unsubstantiated energy-saving and other advertising claims for automotive products.

These web pages are designed to explain the labels consumers see on automotive fuel dispensers and alternative fueled vehicles, and provide information to consumers who are considering buying a car, filling it up, or improving their gas mileage. These pages also provide businesses with guidance on the labeling and advertising of fuels and vehicles.
