Can You Drive Without A Gas Tank Cover

Although modern car tech is really helpful, in the case of the gas tank, not properly securing your gas cap can force some modern cars into “limp mode.” This means the car will limit power output not to exceed 20-30 mph. So, with some cars, driving without a gas cap will not work.
