How can i find the gas mileage on my car

And you know what happens next. How many of you spend time to check the integrity of your gas cap? For most of us, we are only mindful of this part of our vehicle whenever we have to reach for that button to pop open the fuel door. The gas cap contains a rubber seal which forms an airtight protection against the possible entry of air into your gas tank. Unfortunately, this rubber seal degrades over time, forming cracks or failing altogether. Because of this increased air in the fuel, your engine will have to burn more gas and this increases your fuel consumption.

Thankfully, most modern cars now have sensors to detect the integrity of the seal. Replacing these should be pretty straightforward. Did you know that running your engine at idle actually consumes roughly half a gallon to about a gallon of fuel every hour, not to mention the carbon dioxide that your engine pumps into the atmosphere? If this is the case, you can easily do the math. This easily translates to about The same is true early in the mornings. Most of us have this tendency to rev it up in an effort to warm the engines quickly enough. Unfortunately, doing so burns more fuel than actually driving it.

So start your engine, let it run for about 20 seconds, and roll off. It might be counterintuitive, but it makes perfect sense. Running at high speeds in low gear can rob you of as much as 45 percent fuel than what is necessary. So keep this in mind. While these may work, theoretically, its real-world results specifically in your type and make of car may be different.

And in some instances, they do impact fuel consumption but in a negative way. Remember, even products that are endorsed by celebrities do not necessarily mean quality or that they are effective. Use the internet for such a purpose. Even when on the road, you can use your internet-enabled mobile device to search for the petrol stations that offer the cheapest fuels within any given location.

There are even hour convenience stores, fast food restaurants, and burger joints that give you petrol coupons when you purchase any of their products. Did you know that refueling early in the morning can actually save you a dollar or two? You take advantage of the physical properties of petroleum products. Petrol stations have their storage tanks buried deep underground. Early in the morning the ground itself is still relatively cold, making the petrol dense. As the day progresses, temperature rises.

With each increment in the temperature scale, you can expect the molecules of petrol to be expanding. This is because it has already expanded giving you an actual volume of less than 1 gallon. The pumps used in petrol stations measure the flow rate of the fuel passing through the system. Fuel volume is then estimated based on this flow rate.

Sensors in petrol station fuel pumps do not measure the actual density or volume of the fuel; only estimation based on the flow rate. Temperature affects density but not the flow rate. As such, if the fuel pump has been pre-programmed to deliver 1 gallon in 10 seconds, provided the flow rate is at maximum, colder petrol will be denser giving you substantially more fuel.

But just how much more, you say? Well, studies show that refueling on a morning at 59 degrees Fahrenheit will net you 2.

What causes decreased gas mileage?

What many do not know is that you can actually use the same process to tweak the ECU for better mileage, which is technically the opposite of performance tweaking. Do understand however that remapping the ECU of your car is typically an expensive proposition. This effectively shakes, loosens, and dislodges carbon deposits that may have accumulated in your fuel injectors.

This gives you the full functionality of fuel injectors, enabling you to obtain a more efficient and more ideal fuel-air mixture in your engine. This leads to the more efficient burning of fuel, resulting in significant improvement in your gas mileage. Related Post: Fuel Injector Cleaners. A lot of vehicle owners are guilty of this. The reason is simple. If you own a car vacuum cleaner , you know that the powerful suction of your machine can be affected by the degree of blockage or obstruction due to debris and other particles in the bag.

Cleaning or replacing the bag helps bring back the vacuuming efficiency of your gadget. This increases fuel consumption and lowers gas mileage. Not bad for an easy DIY quick fix. Most new cars today already come with electric fans replacing the belt-driven fans of old.

The good news is that you can also replace your engine driven fan with more modern electric thermatic units. In fact, it may be even negligible. But, given that fans are an important component of your car, then installing more efficient ones should help in the overall reduction of fuel consumption.

Here Are Some Things You Can Do Now to Get the Best Gas Mileage on Your Car or Truck

You just came home from work when your wife asked you to go to the grocery for some stuff. Why not just accomplish all of these things even before you drive home? Several short trips can actually consume up to 2 times more fuel when initiated with a cold engine. So, even before you start bringing your car out of your garage, make sure you already have your list of things to do and errands to run to maximize the fuel you will be using for the trip.

The wheel is one of the easiest ways to deck out a car. All you need are some really nice-looking wheels to get the attention of the crowd. Remember that weight really matters when it comes to fuel economy. That is why it is important to choose wheels that are lightweight yet super tough and durable that they can hold the entire weight of your vehicle without adding substantial weight on their own. This is where alloy wheels can be quite a joy to have. Upsizing your wheels can also impact fuel economy. Let us say you have a 15 x 6. Upsizing this to say, 19 x 8. Upsizing it to about 2 inches 17 x 8.

So you see, the greater the upsize of your wheels, the greater the reduction in fuel mileage. As such, it will be wise to really take your time to study which type of wheel will suit your car best.

Maintenance Is Very Important

It is also important to factor in what type of tires you have fitted to your car depending on the conditions you are driving. Our guides on all-season tires , all-terrain tires and winter tires may prove helpful when making a selection. You can also use our tire size calculator here. Not only is this illegal, it is also very unsafe, not to mention very fuel-inefficient.

9 Easy Ways To Increase Your Gas Mileage

Cars run their best and consume less fuel when they are well maintained. Below are a few ways to keep your car in peak condition and keep money in your wallet:. Keep your vehicle well tuned. Simple maintenance—such as regular oil changes, air-filter changes, and spark plug replacements—will lengthen the life of your vehicle as well as improve fuel economy and minimize emissions. Check your tires. Keeping your tires properly inflated and aligned saves fuel by reducing the amount of drag your engine must overcome. Tires that reduce rolling resistance by 10 percent can improve gas mileage by one to two percent for most passenger vehicles.

5 Proven Ways to Get Better Gas Mileage in Your Car

Be weight-conscious. For every pounds of weight in your vehicle, fuel economy decreases by one to two percent. Also, reduce drag by putting bulky items inside the vehicle or trunk instead of on a roof rack. Keep track of your fuel economy. A drop in your vehicle's fuel economy can be a sign of engine trouble. Keep track of your fuel economy by noting the odometer reading and the number of gallons purchased each time you fill up. To calculate your gas mileage, divide the number of miles traveled between fill-ups by the number of gallons purchased.

Most hybrid cars and even some conventional gas vehicles have special gauges that make it even easier to keep track of your fuel economy in real-time, so you can see how your driving habits are impacting your fuel efficiency. The way you drive can have a big impact on your mileage and your wallet.

Consider the following when cruising down the road:. Drive moderately. High-speed driving and jack-rabbit starts increase both fuel use and emissions. Going 65 mph on the highway instead of 75 can cut your fuel use up to 20 percent, and making more gradual stops and starts will bring even more savings. Don't let your vehicle idle for more than a minute. During start-up, your engine burns a little extra gasoline.

However, letting your engine idle for more than a minute burns more fuel than turning off the engine and restarting it. This technology, once only found on hybrid vehicles, is beginning to enter the marketplace on conventional gas-powered cars and can cut fuel consumption by around 5 percent.
