There is a common belief that filling up your gas tank in the cool morning air will get you more fuel. The theory is that gasoline is denser when it is cold, so you get more liquid per dollar before the heat of the day arrives. While it is true that gasoline expands when it gets warm, the actual difference you see at the pump is usually quite small. Most gas storage tanks are located underground, where the temperature stays relatively stable throughout the day. Even so, there are still some good reasons to get your errands done early during a heatwave.
Understanding Gas Density
Gasoline does expand and contract with temperature changes, but the change in your tank is not as drastic as many think. Because gas stations store their fuel deep underground, the temperature of the liquid you pump is not the same as the air outside. The underground insulation keeps the fuel fairly cool even on a very hot afternoon. You might gain a tiny, almost invisible amount of fuel by pumping in the morning, but it will not drastically change your budget. Do not stress yourself out trying to reach the station at sunrise.
Why Mornings Still Help
The best reason to fill up in the morning during the May heat is to avoid the heat itself. Pumping gas in the afternoon when it is ninety degrees outside is uncomfortable and exhausting for anyone. Getting the task done early means you can stay inside or in the air conditioning during the hottest part of the day. You will also find shorter lines and less crowded stations in the early hours before everyone else hits the road. Using your time efficiently is a great way to reduce the stress of your weekly routine.
Avoiding Heat-Related Stress
High temperatures can be hard on your car, and keeping your tank at least half full is a good habit. You should avoid letting your car run on fumes when the weather is extremely hot to keep the fuel pump cool. If you are stuck in a traffic jam in the middle of a heatwave, having plenty of gas provides peace of mind. Focusing on these practical habits will do far more for your driving experience than worrying about gasoline density. Your comfort and your car’s health are the most important things to prioritize this month.
Stick to Smart Habits
Do not feel like you have to follow every single online trick you see about gas prices. Focus on maintaining your vehicle, driving efficiently, and finding the stations that offer the best everyday value. A well-maintained car will save you much more fuel over the long term than any trick about the time of day. If you prefer the morning for the quiet and the cooler air, then by all means keep doing it. Just do not expect it to be a magical solution for rising gas prices.
