Tips for saving on gas:
The tips provided below are intended to apply to the broad spectrum of gas prices that are exhibited throughout the United States and do not attempt to target on specific locale.
General tips:
One of the best ways to cut down on your gas prices is to check Oil and Gas prices daily. Apart from the basic sources you can use to keep track of this information such as CNBC, Yahoo Finance, or BarChart.com, one great site to compare gas prices in your state is gasbuddy.com. This site allows you to search for the lowest price of gas based on city, state, or zip code.
Based on the research you come up with, if there is a spike in oil prices, it may be beneficial to hold off on filling up for a day or two if possible. The reason for this is simply that many times oil spikes are transitory, and some are self-correcting within a few days.
At the Pump:
First, one innovative tip in saving on gasoline is to fill up early in the morning. The rationale behind this is that when you fill up in the morning the ground temperature is still cold. This means that the 'specific gravity' of the gasoline will, as a result of the temperature, be denser than at other times of the day, and thus you will get more gasoline for your money.
Second, resist the temptation to squeeze the trigger of the nozzle to the 'fast mode.' Normal gas pumps typically have three different settings ranging from low, to middle, and high. The rationale behind this is that if you pump at the quickest pace, it is more likely to create vapors in your tank that essentially are recycled by the gas hose into the underground storage tank.
Third, fill up your tank when your tank is half full. The main reason for doing this is that the more gas you have in the tank, the less space you have in the gas tank occupying empty space. This is important because gasoline, given its chemical composition, evaporates very easily. The storage tank has an internal floating roof, which serves as a clearance between the gas and atmosphere that in effect minimizes evaporation.
On the Road:
First, try to keep the ride as smooth as possible. Because a car expends the most gas when accelerating, it makes sense to keep the ride as smooth as possible. In heavy traffic, many drivers are not capable of maintaining constant speed even when traffic is still moving. It is important to simply afford more distance between you and the car in front of you, and try to break as little as possible, thereby cutting down on the subsequent acceleration necessary to get your vehicle moving again, which is what cuts down most on fuel economy. In heavy traffic, if this technique is applied, drivers can get anywhere from 10 percent to 20 percent better gas mileage.
Second, reduce weight in your vehicle. This tip is common sense, but many drivers forget that the weight of their vehicle directly impacts their gas mileage.
Third, close your windows. By closing your windows, you reduce drag on your vehicle, thereby making the vehicle more aerodynamic and increasing fuel efficiency.
Fourth, try drafting techniques. When driving long distance, it has been proven that if you draft behind other vehicles it can significantly improve gas mileage.
Conclusion:
While each tip can result in an increase in fuel economy, it is best to apply the tips above simultaneously to see the biggest increase in your gas mileage.
