1.Buy gas early in the morning or later in the evening:
By getting your gas while it is cooler outside helps because the gasoline tanks are measure the volume of the gas, not the density.Gasoline becomes denser in colder temperatures. Gas pumps are set to measure the volume of the fuel that you pump and not the density.
2. Avoid driving when your gas tank is close to empty :
Driving your car until the gas tank is almost empty can cost you to use more fuel! Dirt can accumulate in the fuel tank over time can be pulled into the engine. This will cause the engine to operate less efficiently and will reduce the miles per gallon your engine runs at.
3.How You Drive Can Affect Your Mileage:
Don't drive too fast or too slow. It takes 20% to 30% more gas to drive at 70 mph than 50 mph.
Coast up to traffic jams by lifting your foot off the gas pedal instead of approaching at full speed and slamming on the brakes. It takes 20% more gas to accelerate to normal speed from a full stop than it does from four or five miles per hour.
Keep a consistent speed while driving on the highway and avoid getting behind slow driving cars where you have to slow down to their pace and then speed up to pass them costing you a surge of fuel.
4.Tire Pressure:
Check your tire pressure weekly. For every pound of underinflation, you can lose up to six percent in gas mileage, so if your tires are five pounds underinflated, you'll use up to 30% more gas.
5. Good Ol Common Sense:
Keeping your car up to date on its maintenance can help you save on gas as well. A poorly tuned car can use more than 25% more gas than a properly maintained car.
6.Park in the Shade!
This minimizes fuel evaporation while the car sits. In summer months, the gasoline in your tank actually evaporates faster when in the direct sun! The shade will help keep your car cool and keep your fuel in your tank longer.
7. Turn the A/C off :
Instead of running your AC, lower your windows; AC can waste up 15% of your gas, However, at faster speeds, studies have shown that the significant drag caused by sunroofs/windows being open nullifies the difference. The point at which AC is most efficient is at 35-40 mph.
8. Don't get Trigger Happy:
When filling up, don't squeeze the trigger of the nozzle to a fast mode. If you look you will see that the trigger has three (3) stages: low, middle, and high.
In slow mode you should be pumping on low speed, thereby minimizing the vapors that are created while you are pumping.
All hoses at the pump have a vapor return. If you are pumping on the fast rate, some other liquid that goes to your tank becomes vapor. Those vapors are being sucked up and back into the underground storage tank so you're getting less worth for your money.
9. Keep Away if you see the Tanks being Filled:
If you see a gasoline truck pumping in to the storage tanks when you stop to buy gas, DO NOT fill up--this causes the the gasoline to be stirred up as the gas is being delivered, and you might pick up some of the dirt that normally settles on the bottom.
10. Half Full or Half Empty?
Fill up when your gas tank is HALF FULL or HALF EMPTY. The reason for this is, the more gas you have in your tank the less air occupying its empty space.
Gasoline evaporates really fast and Gasoline storage tanks have an internal floating roof. This roof serves as zero clearance between the gas and the atmosphere, so it minimizes the evaporation.
Anyone else have a gas saving idea that you would like to share?
