Fill Up Your Car During The Coolest Times Of The Day
– higher temperatures mean that the gasoline you’re pumping is partially going straight into the atmosphere.
Don’t Squeeze The Trigger To The Fastest Setting
– pumping at higher velocity results in more of your gas becoming vapor, which the pump is designed to suck back into the underground tank. Pumping at a lower velocity means you’ll get more gas for your money and less fuel will escape into the air.
Fill Up When You’re Only At HALF
– as your gas tank drops below half-full, it becomes easier for the remaining gas to evaporate. Plus, with all of the impurities in gas these days, the lower your gas level, the better the chance that those impurities that have settled in your tank will stir up and get burned up with the fuel, meaning more pollutants in the atmosphere.
Avoid Gas Stations Where The Gasoline Truck Is Pumping Into Storage
– like in the point above, the gas truck adding new fuel to the underground tanks is probably stirring up the impurities that had settled to the bottom. Adding those to your tank increases that chance that that dirt and grime will get burned and put into the air.
