Why is the gas mileage on my Corolla so poor?
Oxygen sensor that is dirty: An oxygen sensor determines how rich or lean the exhaust gases are as they exit the combustion chamber. The data is utilized by the car’s computer to modify how much fuel is injected into the engine. A decrease in miles per gallon may result from a dirty or malfunctioning sensor. It may also result in a rough idle and failed emission testing.
Fuel injectors that are dirty shoot fuel into the cylinders, where it ignites when it comes into contact with air. The fuel injector system is susceptible to clogging over time. This may result in decreased fuel efficiency, poor acceleration, and insufficient power for the vehicle. If discovered early, the issue can be resolved by simply cleaning the injectors. The injectors could need to be changed as it develops.
Spark plugs that are faulty or dirty light the fuel in the combustion chamber. They can cause the engine to misfire and perform poorly if they’re unclean or operating improperly. This may result in both a loss of power and a significant drop in fuel efficiency.
Mass airflow sensor malfunction: A mass airflow sensor measures the volume of air entering the fuel injection system. It sends that data to the computer of the car, which computes the data and then injects the right amount of gasoline into the car’s air. As the issue worsens, a filthy airflow sensor can efficiently deteriorate fuel, cause a rough idle, and possibly cause stalling.
Tires that are out of alignment or that are low in the air might reduce fuel economy. Regularly checking the alignment and tire pressure can also help to avoid this issue.
Gasoline supply problems, such as a defective fuel pump, can significantly reduce fuel economy. Fuel is transported to the fuel injectors by the fuel pump from the gas tank. The gasoline pump may develop a blockage or stop working. A malfunctioning fuel pump can cause an engine to run poorly because it is not receiving enough fuel. Gas mileage will decrease as a result of this. If this problem is not fixed, the engine will run rough, idle, splutter, and stall.
Fuel filter blockage: A fuel filter clog will also result in poor gas mileage. The gasoline filter removes impurities from the fuel, however it will eventually become blocked. Periodically, fuel filters must be updated.
Stuck Brake Caliper: A jammed caliper on a drum brake or a jammed shoe on a disc brake can significantly reduce fuel efficiency. Furthermore, any brake problem can make driving the car risky. The brake system needs to be checked right away if the car pulls to one side along with the efficiency reduction.
Why does my Toyota Corolla consume such a lot of fuel?
Have you ever wondered why a city car gets a different mpg on the highway? In typical gas-powered vehicles, highway driving consistently results in higher mileage ratings. Take a look at the Corolla as an illustration. Highway driving results in a greater MPG estimate than city driving does.
The cause of this is because of abrupt changes in pace. On the highway, dips in speed and bursts of quick acceleration might result in a 30 percent rise in gasoline consumption. Because of this, abrupt stops and starts can lower fuel efficiency. If possible, try to avoid making abrupt starts and stops when driving outside of urban areas.
If you have a long commute or are planning a road vacation, cruise control on the highway can save you money on gas. It conserves fuel and keeps your car running smoothly. Simply be cautious when driving, pay attention to official traffic signs, and turn off cruise control when necessary.
How can I improve my fuel efficiency?
Now is an excellent moment to consider your driving habits, whether you’re struggling with increased gas prices or trying to reduce your spending. You might be happy to know that there are only five easy actions you need to do to increase your fuel efficiency.
Remove the excess clutter
You should keep some things in your automobile, such as an emergency pack. However, even 100 pounds can cause your fuel efficiency to decrease. You’ll be surprised at how much accumulates if you get rid of unnecessary books, sports gear, and neglected backpacks.
Don’t overlook the exterior of your car either. Remove extraneous accessories that raise wind resistance and reduce fuel economy, like:
- a roof rack
- boxed cargo
- bike stands
- If you need to carry more stuff, rear-mounted cargo boxes are a better choice. While their rear-mounted counterparts typically have a 1 to 5% impact, roof-mounted cargo boxes can lower fuel economy by 6 to 17% while traveling at highway speeds.
- Reduce idling
You might have observed that the stop-start mechanism is already present in many late-model cars. By automatically turning off the engine when the automobile comes to a stop, this enables vehicles to save gasoline. When the brake is let off, the engine restarts itself.
Unexpectedly, idling consumes more gasoline than restarting your automobile and emits 80% more pollution than driving. Consider turning off your engine the next time you are waiting at a stoplight to save fuel.
Maintain a constant speed that complies with the speed limit.
Your car’s fuel economy begins to decline after 45 to 50 mph. And the worse it gets the quicker you go. When feasible, stick within the speed limit and use cruise control. Avoiding abrupt acceleration and severe braking is always recommended because they quickly deplete petrol.
the pressure in your tires
Under-inflated tires might result in a 3% increase in fuel consumption. Additionally, improper tire pressure puts your treads at danger of wearing out more quickly. For the appropriate PSI for your tires, consult your owner’s handbook or the tire wall.
carry out routine maintenance
Spark plugs, connectors, and dirty air filters can all reduce fuel efficiency. Your car will run more efficiently and emit less greenhouse gases if you adhere to the maintenance schedule advised by your dealership. To replace air filters, engine oil, rotate your tires, and other items, schedule frequent tune-ups with your dealership.
Put the five strategies you now know to increase your gas mileage to use and cut down on your trips to the gas station. Do you want to completely eliminate fuel from the equation? Purchasing an electric vehicle can be ideal for you.

Why does my car get bad gas mileage?
The flow of gasoline into the engine can be significantly impacted by a malfunctioning fuel injector or an outdated or unclean fuel filter. One of the most frequent reasons for poor gas mileage is an issue with the fuel system. Gas mileage will decrease when you use your air conditioner more frequently.
Why does gas mileage decline?
It would seem logical that a car’s gas mileage will decrease over time as it ages. Actually, it’s more correct to state that cars with poor maintenance are more likely to experience declining gas mileage over time. In reality, owners who follow the maintenance schedule recommended by the manufacturer are typically less likely to experience significant drops in fuel economy throughout the course of their vehicle’s lifespan.
Maintaining routine maintenance is one of the simplest ways to increase gas mileage. Maintaining fuel-saving maintenance can be challenging, however, when your car approaches 100,000 or even 200,000 miles, especially when you take into account how other factors, such as hot weather, can significantly impair fuel economy.
What should you watch out for to ensure that your automobile continues to run smoothly, just like the day you got it? Start by dealing with the typical issue areas outlined below.
Clogged or Damaged Fuel Injectors
Clean fuel injectors are one of the most frequent causes of a decrease in fuel efficiency. The nozzles that spray fuel into each engine cylinder are known as fuel injectors. To effectively mix with air and ignite inside the engine, the spray pattern of a fuel injector must be extremely exact.
Like a shower head with little pressure, a fuel injector that is unclean or clogged may spray gasoline ineffectively. This can quickly impair your engine’s efficiency and decrease fuel efficiency. The fuel injector nozzles can frequently be cleaned. Other times, if internal damage is the root of a poor spray pattern, the injectors may need to be replaced.
Old Engine Air Filter
For engines to operate, air must be drawn in. Your engine won’t be able to “breathe” if your engine air filter is excessively dusty or blocked. Older engines would require more gasoline to move at the same speed as a compromise. In an effort to make up for a blocked air filter, newer engines could operate less efficiently.
In older cars that rely on carburetors, this issue is more prevalent. Every 15,000 to 30,000 miles, engine air filters should be replaced, but check your owner’s manual to be sure or have it checked at your next oil change.
Dirty Oxygen Sensor
Since about 1996, all newer automobiles have used oxygen sensors in place of the carburetors that many older vehicles used to make sure the engine received the right amount of air and fuel for combustion. An O2 sensor determines how rich or lean the exhaust fumes leaving your engine are, and it sends a signal to the computer in your automobile to change the amount of gasoline injected into the engine.
According to Edmunds, a filthy oxygen sensor might result in inaccurate readings that cause your engine to use too much fuel, reducing efficiency by as much as 40%.
One of the most frequent reasons for a check engine light is a malfunctioning oxygen sensor, which has to be examined and perhaps replaced before the 100,000-mile mark. O2 sensors can thankfully be replaced for a reasonable price, saving you money on gas and ensuring that your car emits as little pollution as possible.
Clogged Fuel Filter
Fuel filters prevent impurities from entering the engine where they could harm fuel injectors and other crucial components. Low fuel pressure and poor engine performance might result from a clogged fuel filter.
Fuel filters should be changed roughly every two years or every 30,000 miles, especially for older vehicles. Bring your car to your neighborhood Firestone Complete Auto Care for a fuel pressure test if you think your poor gas mileage is due to a filthy fuel filter.
Worn Out Piston Rings
Your engine’s piston rings seal against the cylinder walls to produce compression in the cylinders. When piston rings are worn out, they can no longer form that seal, which causes the engine to lose pressure. As a result, fuel economy is completely lost.
In addition to lubricating the piston rings, engine oil also improves fuel economy. Making ensuring your automobile receives routine oil changes with the manufacturer-recommended oil type described in your owner’s manual is the best option.
Bad Ignition System Parts
The air-fuel mixture in the engine is ignited by the coils, spark plugs, and wires that make up the ignition system. The engine may misfire if one or more of these components is broken. When the fuel in an engine cylinder does not ignite, a misfire happens. Unburned gasoline wastes gas and reduces fuel efficiency because it cannot power your car.
If the ignition system is to blame, you can suffer rough idling, stumbling, or a general loss of power from the engine. The spark plugs are the ignition system’s most frequent cause of failure.
Old or Incorrect Engine Oil
There is a widespread misconception that heavier engine oil is necessary to stop leaks in older vehicles. The theory holds that heavier oil would be less likely to seep through the breaches because internal seals and gaskets deteriorate and shrink with time.
Older seals can be made more flexible and perform a better job of sealing with the use of seal conditioning additives included in specially designed “high mileage engine oils.” Additionally, a small increase in viscosity is made to aid in the better sealing of worn piston rings. However, heavier oil actually increases friction between moving elements of the engine, reducing fuel efficiency.
Modern engines need the proper motor oil to stay lubricated and protected. Regular oil changes using the type of oil recommended in your owner’s handbook are the best thing you can do to maintain your car’s fuel economy. High mileage engine oils may aid in lowering oil use and leakage, but they will limit some of the possible fuel efficiency.
Dirty Mass Airflow Sensor
Mass airflow sensors calculate how much air is entering the engine. Similar to an oxygen sensor, the mass airflow sensor transmits information to the onboard computer so that it can determine the proper air-to-fuel ratio in the engine and modify the fuel injection as necessary. A filthy airflow sensor, on the other hand, will make the car’s computer calculate the correct air-fuel ratio incorrectly, resulting in poor fuel efficiency or even engine stalling. It is recommended to use a specialized cleaning spray to clean mass airflow sensors.
Underinflated Tires
Because an underinflated tire has increased rolling resistance with the road and a somewhat smaller effective diameter, low-pressure tires are frequently to blame for decreasing MPG. To alert drivers when their tires need more pressure, modern cars are equipped with tire pressure monitoring systems (TPMS). However, the alarm is only activated when there has been a significant loss of PSI. Even if the TPMS doesn’t yet show a warning, running five PSI below the optimum pressure is enough to increase drag and reduce fuel economy.
Regularly checking your tire pressure and adding air as needed is one of the simplest ways to maintain fuel economy. Using Bridgestone Ecopia tires, which are designed with fuel efficiency in mind, is another shrewd decision. With fewer trips to the gas station, Ecopia tires’ reduced rolling resistance tread can help you save money and fuel. Ecopia tires are best used in conjunction with other gas-saving maintenance, but they do contribute significantly to a greener, more cost-effective journey.
Worn or Stuck Brakes
In addition to being risky to drive with worn-out brake components, sticky brakes may also be lowering your MPG. For instance, a locked brake caliper or sticky brake pads will hinder the forward motion of your car. Brake drag makes your engine fight with the brakes all the time to move, drastically decreasing fuel economy. Make sure you routinely check your brakes, or just bring your car to Firestone for a thorough brake inspection.
Poor Alignment
You may be paying more for gas because of your wheel alignment if you’ve been driving for some time with a crooked steering wheel. Misaligned wheels create difficulty to driving straight down the road, similar to low-pressure tires. Fighting this resistance all the time makes the engine work harder and reduces fuel efficiency. Fortunately, a quick service like wheel realignment is available at any Firestone Complete Auto Care shop nearby.
