People are more concerned with increasing their fuel efficiency because the cost of gas is continuously shifting and they want to save money. Depending on whether the vehicle is two-wheel drive or four-wheel drive, the Toyota Sienna minivan achieves fuel economy ratings of 16 to 18 miles per gallon in the city and 22 to 24 miles per gallon on the interstate. You may increase the fuel efficiency of your minivan by altering your driving habits and keeping up with routine maintenance on your Sienna.

Step 1
Modify your driving technique. Instead of accelerating quickly, press the gas pedal more slowly for a smoother acceleration. Another piece of advice is to anticipate stops to use your brakes less. Take your foot off the throttle and gently come to a stop when you notice a stop sign or stop light up ahead. Set your Sienna’s cruise control to between 60 and 70 miles per hour when you’re on the freeway.
Step 2
Keep track of your Sienna’s maintenance plan and get oil changes every 2,500 miles. One of the best methods to increase your mileage is to take care of your engine. To access the maintenance schedule for your Sienna, click the “Toyota Maintenance Schedule” link under Resources at the bottom of this page, then enter your model, year, and mileage interval. Maintaining your vehicle’s upkeep includes changing soiled air filters, keeping all fluids topped off, and checking the pressure of your tires.
Step 3
Drive with caution during rush hour. On the interstate or in the city, idling and stop-and-go driving wastes gas because they don’t move you very far. Your fuel efficiency will improve if you drive during periods of light traffic and try to use the motorway as much as possible.
Take anything extra out of your minivan. Your Sienna certainly transports numerous kids and their equipment to sporting events, but extra gear adds weight to your car and strains the engine. Remove all racks from the top of the roof and extra weight from the Sienna’s interior while not in use. The Sienna loses aerodynamic efficiency when it has roof racks.
Go Easy on the Pedal
Rapid acceleration, braking, and speeding up produce waste gas. Poor driving practices can reduce fuel economy by 15% to 30%, depending on the type of vehicle. A sensible driving style can result in gas savings of between 31 cents and $1.24 per gallon, based on the current national average of $3.09 per gallon (for regular gasoline).
Slow Down
Above 50 mph, gas mileage efficiency starts to decline. According to fueleconomy.gov, drivers spend an additional 22 cents per gallon of petrol for every five miles per hour that they travel over the speed limit. Speeding can lead to a 7% to 14% reduction in fuel economy, even though each vehicle has its own ideal speed for fuel economy. You can save 22 to 43 cents per gallon by driving more slowly.
Leave Extras at Home
Your car’s gas mileage can drop by up to 1% when you add 100 pounds to it. Relative to the vehicle’s weight, the reduction is as follows: Increased weight has a greater impact on smaller vehicles than it does on larger ones. Expect to pay up to 3 cents more per gallon for every 100 pounds more weight.
Turn off the Car
The U.S. Department of Energy estimates that idling uses many billion gallons of fuel annually and gets 0 miles per gallon. A car should be shut off if the anticipated delay will be greater than 10 seconds, according to the California Energy Commission (CEC), as an idling vehicle can use up to one gallon of gas per hour.
Check Tire Pressure
Gas mileage can be significantly increased with just a little bit of car maintenance. 1.25 billion gallons of gasoline annuallyor about 1% of total consumptionare wasted on underinflated tires, according to the U.S. Department of Energy. About 2 pounds per square inch (psi) can be lost by tires per month. Each tire that is 10 psi underinflated affects fuel efficiency by around 3.3%. The fuel efficiency of a car would be reduced by a significant 10% with four tires that are 10 psi underinflated, costing an additional 31 cents per gallon.
Not what is inscribed onto the tire itself, but rather what is recommended in your vehicle’s owner’s handbook (which is also displayed on a sticker inside the driver-side door jamb).
Replace Spark Plugs
According to the National Institute for Automotive Service Excellence, defective spark plugs can cost drivers up to 94 cents per gallon at current pricing and can reduce fuel economy by up to 30%. There’s a strong probability that spark plugs that aren’t firing properly are to blame if a car’s fuel efficiency suddenly lowers.
Check the Alignment
Misaligned tires don’t roll freely; they drag. A 10% reduction in fuel efficiency, or 31 cents per gallon, can be caused by improper alignment. The tires may also deteriorate more quickly.
Uneven tire wear from unbalanced tires might lead to decreased gas mileage (symptom: shaking in the steering wheel). To enhance tire performance and fuel efficiency, tires should be rotated and balanced in accordance with the owner’s manual for the vehicle.
Fill Your Tank Early in the Morningor Late at Night
Fuel is distributed based on volume. The fuel will be denser if you fill up when it’s cooler outsideearly in the morning or late at nightand avoid the heat of the day. You will therefore receive more petrol for your money as a result.
Really, the Sienna gets 36 mpg?
The Toyota Sienna is a hybrid in 2022. A third electric motor is added to the existing two electric motors and 2.5-liter four-cylinder engine to form the optional all-wheel-drive system. Its battery stores energy from the engine and brakes (it is not a plug-in hybrid like the Pacifica Hybrid, which is also available but costs more and has an all-electric range). 245 horsepower is the total system output, which is less than its V6-powered rivals.
However, fuel efficiency is significantly better. In EPA testing, Toyota predicts the Sienna will achieve 35 mpg combined with all-wheel drive and 36 mpg combined with front-wheel drive. On a 454-mile road trip, we averaged 39.4 mpg without trying to drive economically. 22 mpg combined for the Odyssey, Carnival, and V6-powered Pacifica. Given how people often drive minivans, this gap should allow you to save hundreds of dollars annually on petrol. It also appears to considerably exceed any performance advantages the Sienna may have over its competitors.
How can I extend the life of my gas?
Here, we examine some of the top techniques to improve fuel efficiency and reduce your fuel costs.
- Take care of your car.
- Get rid of extra weight.
- tire pressure should be set properly.
- Fill your tank only as much as is necessary.
- Drive carefully.
- Do not idle.
- Utilize the engine stop-start if you have one.
Does Eco Mode reduce fuel use?
To improve fuel efficiency, Eco Mode limits the performance of the engine and transmission. This implies that even if you pound on the throttle, your car won’t accelerate as quickly as it possibly can. Instead, it will carry out all of the manufacturer’s permitted actions while installing Eco Mode.
Eco Mode fine-tunes all of the fuel, air, and other key adjustments to obtain the most fuel efficiency out of your car without any negative side effects, in addition to restricting both engine and gearbox performance. Only a minor loss in power and responsiveness will be apparent.
When you engage Eco Mode on your car, the manufacturer essentially imposes a set of limits. Although this isn’t always a bad thing, they didn’t have any cutting-edge technology.
Is gas saved when using the cruise control?
Yes, generally speaking. Due to its capacity to maintain a constant pace, cruise control can help you become more fuel-efficient and can help you save on gas on average by 714%. In contrast, the constant acceleration and deceleration caused by the driver’s foot on the pedals might use up more gas.
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.
