Bennington Chevrolet’s Reasons To Avoid Topping Off Your Tank:

Gas topping damages your vehicle 

  • Did you know that gas topping can damage your vehicle’s vapor collection system? It’s true! And your vapor collection system is designed to reduce harmful emissions and manage fuel vapor making it a pretty important part of your vehicle. So, overfilling your tank sends excessive fuel into the charcoal canister or carbon filter which is strictly designed for vapor only. When fuel gets into this system, it will affect your vehicle’s performance and could damage the engine meaning hefty repair costs. 

Gas topping hurts your wallet 

  • Often times, gas stations are equipped with a vapor recovery system that will feed vapors and gas from the pump back into the station’s tank once your tank is full. Why? This is to prevent vapors from escaping into the open air and environment, according to the EPA. That means an excess gas pumped into the tank that you’ve already paid for could end up back in the gas station’s storage tanks. Doing so can also cause damage to the station’s vapor recovery system which leads to the following…. 

Gas vapors are harmful to people & the environment

  • Topping off your gas tank might be a good idea but if any gas spills out of your tank and onto the ground it can cause harmful effects to both the environment and people. A damaged vapor recovery system will not be able to effectively protect people from harmful vapors which will lead to bad ozone days. So long story short, don’t overfill or top off your tank!
