Gas Mileage 101

The number of miles your car can drive on one gallon of gas is referred to as gas mileage, or miles per gallon (MPG). This is also known as fuel economy. The more miles per gallon your car gets, the more fuel efficient it is.

To achieve the highest level of fuel economy possible for your vehicle, the key is regular maintenance and quality automotive parts and products. The better you care for your car, the better it will perform and the longer it will last.

To understand your vehicle’s routing car maintenance needs, refer to the owners’ manual. If you do not have the owners’ manual, you can download one online for your make and model vehicle, or you can ask a trusted Carmel IN mechanic for a recommended auto maintenance schedule.

Calculating Your Vehicle’s MPG

There are 7 simple steps to calculating your vehicle’s miles per gallon. It will take some time, as well as some basic, elementary-level math. Here’s how to determine a car’s MPG:

➊ Fill Your Tank All the Way – Be sure your gas tank is topped off all the way.

➋ Record the Odometer Reading – Write down the number of miles that reads on your odometer. You may also set your odometer’s trip meter is applicable.

➌ Use Up All Your Gas – Drive your vehicle as you normally would until the gas tank is on E again. This should take a week or so depending on how much and how far you drive on a daily basis.

➍ Record the Odometer Reading AGAIN – Write down the number of miles that shows on your odometer.

➎ Record the Number of Gallons Refueled – Write down how many gallons of gas it took to refuel your tank all the way full.

➏ Do the Math – Subtract the first odometer reading from the second reading. This will tell you how many miles your car drove on one tank of gas.

➐ Do Some More Math – To get your MPG, divide the number of miles you drove by the number of gallons it took to refill your gas tank.

Does Your Car Have Good Fuel Economy?

The U.S. Environmental Protection Agency provides us with a fuel economy rating system that evaluates vehicles on a scale from 1 to 10, with lower numbers being worse and higher numbers being better. If your vehicle has an MPG less than 14, you are assigned a rating of 1, while a MPG of 44 or more rates a full 10.

How Does Tire Width Affect Gas Mileage in Cars?

Posted on February 25, 2021 by Autohaus

Today, everyone is looking for the answer to better gas mileage. Vehicle owners and drivers are on a constant hunt for secrets, miracle cures, rises in the economy, and blatant luck to reduce gas mileage, prices, and fuel consumption. There are several reasons why vehicles can get good or bad gas mileage. There are so many factors that affect this area of concern; however, there is one variable that is hardly discussed but highly influential when it comes to fuel mileage. This variable is tire width. Tires have a large influence on how a car or truck operates on the road.

The 101 on Gas Mileage and Tire Care

There are two things to consider when thinking about tires and their effect on gas mileage; one is wind resistance, and the other is rolling resistance. When a car is driving at higher speeds, it experiences higher wind resistance; this means lower fuel economy. Rolling resistance is the impact the road has on the tires, and how it affects drivability. If you change the features (size and width) of your tires, it will then influence the interaction it has with the road, thus affecting the gas mileage. This is where tire width can begin to influence gas mileage.

Tire Size and Width Influences Gas Mileage

Many people believe by changing the height of a car’s tires, they can increase its fuel economy. This is not a reliable idea. You see, speedometers are specifically calibrated to the number of revolutions a set of tires makes per mile while driving. If the original set of tires is replaced, the calibration will be off and changes in fuel economy will be blurred. Shorter tires will calculate at higher gas mileage because they will make so many more revolutions per mile. This negatively affects fuel consumption because it makes the car’s engine work at a higher rpm to achieve the same speeds. Taller tires will do just the opposite while still offering an inaccurate reading.

Tire Width versus Gas Mileage

Tire width is one of the only tire size factors that can influence gas mileage in a positive way. For example, a narrow tire will have less wind resistance, rolling resistance, and weight, thus, increasing gas mileage. If choosing a narrower tire, be aware that they can make the car’s handling characteristics more difficult to control. It is best to always install the proper size tires for your particular vehicle. A professional tire tech or mechanic will have no problem helping you figure this out. Also, keeping your tires fully inflated can improve gas mileage.

Don’t Throw Away Your Hard-Earned Cash. Save Gas Money With These Tips!

Get Better Fuel Efficiency in 2021!

Remove Unwanted Junk From Your Vehicle

The first step to reducing fuel consumption is reducing any excess weight within your vehicle. Remove any heavy items that have been stored there for some time. Things like sporting equipment, clothes, books, trunk items, electronics, building materials, hobby supplies, and garbage can add unnecessary weight to your car. The heavier a vehicle is, the more fuel it requires for motion, so this is the easiest and quickest way to immediately improve gas mileage on your own.

Try Not to Idle So Much

Another approach to saving on fuel is to avoid long idle times in your car. Next time you go to pick up pizzas for the family, park and walk into the store rather than pulling up and allowing your car to run while you are inside paying. Unbeknown to ordinary drivers, this action causes our fuel to burn up almost as fast as it would if we were driving. Avoid taking lunch breaks in your car, leaving it on while applying makeup, or listening to music before school. This will eat your fuel up faster than you can say fuel economy!

Embrace Better Driving Habits

If you really want to reduce your gas mileage and fuel consumption, try driving better. You may believe you are a fantastic driver, especially if you have a solid record. But this does not mean you can’t improve on your skill. Driving fast, erratically, taking off fast, and coming to abrupt stops can cause your vehicle to use more fuel than it needs to. It can also damage your vehicle’s inner workings. Try driving slower, smoother, and in a more consistent manner can help reduce fuel consumption and save you money in the long run.

Using the right fuel grade is also important to ensure optimal gas mileage and overall vehicle performance!

Have Your Car Serviced Regularly

Perhaps the most effective and recommended way to reduce fuel consumption is to make sure your car is operating optimally. The only way to ensure top vehicle performance is to have your vehicle serviced regularly, and to stay on top of all its necessary factory scheduled maintenance. Car maintenance services like oil changes, automotive fluid changes, air filter changes, engine cleaning, tire rotation and balancing, and tune-ups all contribute to how efficient your car’s fuel consumption will be now and in the future.

5 Ways to Improve Fuel Efficiency:

Check the Tire Pressure

Under-inflated tires are a huge contribution to poor gas mileage. It can increase the fuel consumption as much as 6%. By regularly checking your tire pressure and ensuring they are properly inflated, you can save more fuel with every trip. Tires should be inspected once a month and done so before driving, while the vehicle is still cold. Do not let radial tires fool you; they may look inflated but can actually have low tire pressure. Always check anyway.

Use Less AC

During the hot summer months, your car’s ac unit contributes to almost 10% of increased fuel use. On cooler days, avoid using the car ac unit by rolling down the windows and keeping a cool beverage in your cup holder.

Avoid Jack-Rabbit Driving

Jack-rabbit driving looks similar to a person learning to drive in first gear for the first time. Abrupt starts and hard stops is what we refer to as jack-rabbit driving. Aggressive driving causes your vehicle to use more gas. This can happen when we are stuck in traffic, or in a hurry to get somewhere. Avoid this type of driving and increase your gas mileage.

Obey Speed Limits

Another way to get better gas mileage is to maintain a steady speed when driving. Accelerating and decelerating causes your car to pull more fuel. If you typically drive ten miles over the speed limit on the highway, try going slower to save gas. You will see a difference within a few days. Also, on long stretches of highway, use cruise control. This helps regulate the amount of fuel being consumed per mile.

Drive Less

The most obvious, yet, difficult remedy to poor gas mileage is too much driving. If you can make the commitment to drive less often, it can greatly reduce the amount of fuel you consume per week. Try taking buses, organizing car pools, and walking to closer destinations. Not only can this be good for your fuel budget, it is a great way to improve the environment.
