How many times have you put gas into your car and driven off with the gas cap still sitting on top of the pump? If you’re like me, that’s happened at least a few times.

But some of the new Ford cars are going to have a new system so you can prevent that from happening. The automaker’s new Easy Fuel system is a feature where you never need to remove a gas cap again. Instead, the place where you put the gas pump’s nozzle is simply a “spring-loaded flapper door” that opens and closes on its own.

Once you’re done fueling, the Easy Fuel system seals itself. In addition to being quicker and less annoying than a gas cap, the new system also emits “fewer evaporative emissions into the environment.”

Motorists are expressing interest in the new system, too. More than 75 percent of women surveyed and about 67 percent of men said this would be a feature they’d appreciate regardless of what type of car they drive. The 2008 Ford Explorer and the Mercury Mountaineer already have this new system installed on them. It’s also going to be a standard feature on the 2009 F150s, the Ford Flex models and the Lincoln MKS. Within the next five years, the automaker hopes to integrate the Easy Fuel system on all of its brands and models.
