From Dach's words....... Personally, I hope GM never adopts this idea. Great for city people; crappy for rural people who drive gravel roads, or work oil rig sites, construction sites, etc. I have 3 friends with them on farms and they replace more fuel filters than ever before. Ever open up your gas lid and see dirt, dust and gunk around your cap from muddy/gravel roads? Without the cap all this crap covers that little “flap” that keeps gas from spilling out and as you push the gas bowzer in, it all falls into the tank.
That is why Ford now has an “accessory” through their parts department for a new gas cap for these capless vehicles. Makes you wonder why if it is such a great idea.
