When to Pump Gas?

Gas Pump Tip #3: One of the most important tips is to fill up when your gas tank is half full (or half empty depending on your orientation). The more gas you have in your tank, the less air occupying the empty space in your tank.

Is it better to pump gas in the cold?

Gasoline might be more dense in the morning, but you probably won't see a difference in your gas mileage. It's true that gasoline is more dense when it's cold, which means typically it's most dense in the early morning hours when it tends to be coolest outside.

How do you know when your gas tank is full?

You pull into the nearest gas station and pull up to a dispenser. You swipe your credit card, put the nozzle in, and squeeze the handle. You watch the numbers on the read-out climb and climb when suddenly *click* the handle disengages. Anyone who's pumped gas knows this means your tank is full.
