Whether we want to round up or simply get as much gas into the tank as possible, some of us top off our vehicles by squeezing in a little more, even after the pump shuts off to indicate the tank is full. Can adding that extra bit of fuel damage components in your car’s fuel system?
Adding more fuel after the gas pump clicks off can damage the charcoal canister by saturating it with fuel and cause the check-engine light to illuminate. If the onboard refueling vapor recovery (ORVR) is damaged, it won’t adequately capture those harmful vapors. The system typically lasts the lifetime of a car, but topping off could lead to an avoidable repair that could cost hundreds of dollars.
