Gas mileage is the ratio of the number of used gallons and the number of traveling miles. MPG is used to measure this figure. For example, if your vehicle travels 30 miles per gallon of fuel, it gets 30 MPG.

MPG on highways is often higher than in city driving. The latter necessitates idling, slower speeds, and higher revolutions.

Causes To Lowered Gas Mileage 2015 Toyota Corolla

Old Oil

Gas consumption varies greatly due to a wide range of outside factors. Among them, oil takes one of the greatest toll on fuel consumption.

Failure to supply cars with a suitable and new power source will make them less energy-efficient. Worse, old oil can lead your vehicles to operate improperly during the journey.

Thus, changing the oil regularly lowers your fuel consumption. For vehicles of newer models, oil and fuel technologies have been improved, saving you several oil replacements.

Compared to every 3,000 miles like previous models, innovative ones will call for new oil every 7,000 – 10,000 miles.

Under-inflated Tires

Under-inflated tires are a possible culprit behind the decrease in fuel efficiency. Check your cool tires for an accurate pressure reading and fill them up at the right time.

Poorly inflated ones will adversely increase friction while extending the rotating times during the same distance.

Wrong Gear

Cars with stick shifts should be equipped with the appropriate gear. A lower gear will work best for heavy loads to save your engine from working too hard.

If you frequently travel at higher speeds, a higher gear would be a better choice. Always listen to your engine. Underworking or overworking engines will waste your gas.

Apart from normal gears, Toyota Corolla also has B gear of which you need to be aware to put in the right gear. So keep that in mind!


Aggressive driving is a bad habit, adding up to your monthly fuel consumption bill. Fast driving, quick accelerating, and sudden stop will also lead to high oil use.

Thus, if possible, you should drive at a reasonable speed and accelerate slowly. It would be best to spare enough space between the front car and yours.

This way, you can ensure personal safety, stop gradually, and don’t need to slam on the brakes. Your fuel efficiency will be enhanced by a brakeless and natural deceleration.

Another issue with fuel consumption is air conditioning. Using air conditioning too much pressurizes the engine and lowers the operating efficiency.

To deal with this problem, you can open a window to lower the internal temperature.

Keep The Tire Pressure Stable

Keeping the tire pressure stable is always one of the most annoying chores for drivers.

But, it is worth noting that maintaining a proper PSI in your tires is the most simple method to improve energy efficiency.

There are some cases when the car sounds like a flat tire, but it doesn’t. So, it’s best to examine it carefully to track down the root before inflating the tire.

Maintain Stable Speed

A large amount of fuel is wasted due to constant acceleration and braking. While these two practices are unavoidable, try to accelerate slowly and predict the surrounding people and vehicles’ movements.

Coasting between stop lights is also highly recommended.

Inspect The Air Filter

A dirty air filter will restrict the airflow into the engine. This can harm the overall performance and economy.

It is simple to check, remove, and change air filters. To test its condition, hold the filter under the sun.

If no light can penetrate it, you should replace it with a new one.

Minimize Idle Engine State

Always check the frequency of your engine’s unnecessary operation. Warm up your vehicle for morning commuting, leave the car on while waiting for a train, or run into the grocery store.

All these practices can waste a valuable amount of energy and fuel.

Get acquainted with turning off your car when you must stop for a long time.

Turn Off Energy-Consuming Devices

Air filters, fuel injectors, oxygen sensors, and spark plugs seem unrelated to your fuel consumption. Yet, they have a serious impact on your energy efficiency.

Make sure all these parts are well cleaned and operating correctly. If unnecessary, try to turn them off to save energy.

Clean Out The Car

If you have a leisurely attitude towards the cleanliness of your car, you will surely fall into this category.

Let’s go through your car and identify anything needing to be tossed out. The more weight your car lugs around, the more fuel it consumes.

Back Of The Bling

New tires and wheels will surely improve handling. Yet, when these parts and stock ones are not the same sizes, more rolling resistance will be created, thereby increasing fuel costs.

For this reason, when upgrading your wheels and tires, you should keep the old ones for comparison.

It would be best to stock some spare tires and wheels with compatible sizes and good performance in the garage.
