Use only unleaded gasoline, please. Choose 87 (Research Octane Number 91) or above as the octane rating. Engine knocking may occur if unleaded fuel with an octane value less than 87 is used. Damage to the engine might result from persistent knocking. In the United States, the gasoline you use must, at the very least, adhere to ASTM D4814 criteria.
Note:
Very seldom, the gasoline brand you are using may be the root of your vehicle’s driveability issues. If you continue to have issues with driveability, try switching the gasoline brand. Consult your local Toyota dealer if this does not resolve the issue.
To prevent the accumulation of engine deposits, Toyota advises using gasoline with detergent additives.
According to the EPA’s lowest additives concentration program, all gasoline sold in the United States has a minimal amount of detergent additives to clean and/or maintain clean intake systems.
In some cities, you can get reformulated gasolines as well as gasolines that contain oxygenates such ethers and ethanol. If the fuels meet all other conditions, they are usually acceptable for usage.
As a result of the formulas’ ability to lower vehicle emissions, Toyota recommends these fuels.
Utilize only gasoline with up to 15% ethanol.
AVOID using any flex fuel or gasoline that may contain more than 15% ethanol, even if it comes from a pump marked E30 (30% ethanol [
Make sure the gasoline you use in your car has an octane value no lower than 87.
MMT is an octane-boosting ingredient found in some gasoline (Methylcyclopentadienyl Manganese Tricarbonyl).
Toyota does not advise using MMT-containing gasoline. Your emission control system may suffer if fuel containing MMT is utilized.
On the instrument cluster, the malfunction indicator lamp may turn on. If this occurs, speak with your local Toyota dealer about service.
While accelerating or going uphill, you could occasionally experience light banging for a brief period of time. There is no cause for alarm because this is usual.
Notice:
Use only appropriate fuels. The engine will be harmed if the wrong fuels are utilized.
Use only unleaded fuel.
Your car’s three-way catalytic converters may become damaged by leaded fuel, which will disrupt the emission control system.
Use only the type of gasoline that was specified previously.
Other gasoline may harm the fuel system or impair the performance of a vehicle.
Use of unleaded fuel with an octane number or rating below the above mentioned level may result in chronic strong knocking.
In the worst case scenario, this can result in engine damage and nullify the car warranty.
Stop using a new type of fuel if poor driveability (poor hot starting, vaporization, engine knocking, etc.) is experienced after doing so.

Do Toyota vehicles need premium fuel?
What octane fuel is recommended for my Toyota? My people believe that it is advantageous to fill up their Toyota with high-octane or premium gas (90 octane or higher). The truth is that no Toyota uses a fuel grade greater than 87, with the exception of the Toyota Supra, which has a BMW engine.
Which Toyota models need premium fuel?
Premium gasoline has a higher octane rating than regular fuel and will burn cleaner, quicker, and more efficiently, which can increase power and fuel efficiency. In high-compression and turbocharged engines like the ones featured in the 2021 Toyota GR Supra, high-octane premium fuel performs best. The Toyota GR Supra is the only Toyota car that suggests premium fuel. For more information and recommended fuel, consult your Toyota owner’s manual.
What Are the Differences Between Regular and Premium Fuel?
The octane rating is the primary distinction between regular and premium gasoline. In most states, regular gas is rated at 87 octane. In the majority of states, premium gas has an octane rating of 91 or 93. More detergents and other additives with hydrocarbons that are less susceptible to predetonation in your engine are frequently found in fuel types with higher octane ratings. Your engine may knock or ping, and the cylinders may experience unusual wear as a result of predetonation. Premium fuel reduces the possibility of predetonation and will ignite at the precise moment required for performance optimization.
Which gas engine does the Highlander have?
A 2.4-liter four-cylinder engine with 265 horsepower is standard on the Highlander, and it is mated to an eight-speed automatic transmission and either front- or all-wheel drive. Although we haven’t driven this particular version yet, we will be able to remark on its performance then. The Highlander Hybrid has a 2.5-liter four-cylinder engine and two electric motors working together to provide 243 horsepower. This variant offers both front- and all-wheel drive and a continuously variable automatic transmission (CVT). Utilizing Toyota’s hybrid expertise, this engine offers customers a vehicle that is far more fuel efficient than the normal model without significantly reducing performance; on our test track, the most recent hybrid model we examined was capable of reaching 60 mph in 7.3 seconds. The ride is excellent for serving as the family chauffeur because of its boring but stable handling. Potential customers in this market may be aware that the Ford Explorer is also available in a hybrid version. But if you compare the fuel efficiency of different utes, the Toyota comes out on top.
What occurs if you use 93 gas instead of 87 gas?
Most of us regularly operate a car or truck that runs on ordinary, unleaded fuel. This makes filling up at the gas station rather straightforward. But occasionally, someone can unintentionally use a different type of gasoline than usual to fill their car.
The majority of today’s cars and trucks are equipped with electronic fuel management systems that can detect the difference between ordinary and premium gas (lower and higher octane) and modify the ignition timing and fuel injection accordingly.
Don’t worry if you mistakenly put a higher octane blend (such 91, 92, or 93) into your tank than the standard 87-octane fuel. Actually, you’re using a different gas blend to fill your car or truck, which means your engine will operate differently as a result. There might be a slight difference in how the car feels and you might see better gas mileage, but that’s about it.
Premium Gas Vehicles
Do not become alarmed if the manufacturer of your automobile or truck suggests premium fuel for your vehicle but you instead use normal. Even though premium is advised, you are not required to use it; the engine can run just as well on standard gas.
You can run into issues if you use standard fuel when your manufacturer calls for premium. How well your car or truck will handle normal petrol depends on the sophistication of your fuel system as well as other elements like how your engine is tuned, what the timing is, and how hot it runs. Most of the time, the car will run just fine, although you might notice less power and reduced gas mileage. Because the fuel isn’t burning properly in more acute cases, you might hear engine banging or valve chatter. You should take it to your mechanic because these things might harm your engine.
Diesel Vehicles
You must be aware of how diesel fuel and unleaded fuel differ from one another and which your car needs.
Inadvertently using unleaded fuel in a diesel-only vehicle will actually reduce the lubrication that diesel provides for the car’s components. As a result, there will be significant damage from the pieces grating against one another.
The damage may not be as severe if you fill your ordinary gas vehicle with diesel, but you won’t travel more than a few miles before the engine starts to splutter, cough, and lose power. You’ll be able to drive the vehicle once more when you replenish the diesel tank and flush out the fuel lines.
Do yourself a favor and refrain from starting your automobile if you have the wrong kind of gas in it and haven’t done so yet. When the incorrect fuel is pulled up into the fuel lines, engine damage results. Call a mechanic instead, and ask them to fix the problem.
What happens if premium and normal gas are combined?
Can I combine unleaded and premium gas? Yes, drivers are allowed to mix the two fuel kinds. According to The Drive, the mixture of gas types will produce an octane level somewhere in the center, which the vehicle “will survive.
Does premium fuel provide greater mileage?
Is higher octane fuel therefore more effective? Simply put, no. Paying more for premium gas doesn’t, by itself, improve how well your car runs or how much gas it uses. Your fuel mileage will change if you give your automobile the gasoline it needs to function smoothly and efficiently without endangering the engine.
Premium Gas Offers Better Performance
This myth is partially true and partially false. The majority of automobiles operate at the same level of performance whether you use standard or premium petrol. You’ll only notice a noticeable difference between the two with particular car models and engine types.
You Need to Use Premium Gas if It’s in Your Car Manual
This myth also rests on circumstantial evidence. Many automakers, like GMC, Ram trucks, and the works, will indicate in the owner’s manual for some of their cars whether they advise or demand the use of premium gasoline. What counts is how these two terms differ from one another.
There are certain advantages to using premium gas when the manual advises against it, but using regular gas won’t hurt your car. It won’t void your warranty in this situation either. Premium gas could potentially improve the performance of these vehicles.
But if the owner’s handbook specifies premium fuel, it signifies the engine does really require higher octane levels to operate properly. Using conventional fuel in these vehicles could potentially harm the engine, and your warranty won’t cover these damages.
Make sure you carefully study your owner’s manual before buying a new or used automobile to make the best decision. Save yourself the money if it’s not necessary.
Premium Gas Lasts Longer
So, is premium fuel more durable? This appears to be a lure of using the ostensibly higher grade fuel for many people. Who among us wouldn’t like to visit the petrol station less frequently?
Regrettably, premium gasoline contains nothing that would extend its shelf life relative to other fuels purchased at the pump. Since the higher octane levels are what set them apart, the only true advantage is a decreased risk of engine knocking, which poses no danger with most contemporary fuel systems.
Premium Gas Cleans Your Engine
This myth is untrue, much like the idea of living longer. The majority of engines are effective in removing residue. You’re in better shape keeping up with routine maintenance checks if you’re worried about the cleanliness of your vehicle’s components.
What automobiles exclusively need premium fuel?
A List of 15 Regular Cars That Use Premium Fuel
- Cadillac Envision (with 2.0L turbo)
- Bugatti Regal (all models)
- Chevrolet Regal TourX (all models)
- Cadillac Equinox (with 2.0-L turbo)
- CORVETTE MALIBU (with 2.0-L turbo)

What issues are there with Toyota Highlanders?
Similar problems with the motorized tailgate and air conditioning system plagued the Toyota Highlander’s previous version from 2008 to 2013. A few owners have also complained of oil leaks from the engine and clunking sounds they hear when rotating the steering wheel.
Is the Toyota Highlander a dependable vehicle?
The Toyota Highlander has a 4.0 out of 5.0 reliability rating, placing it seventh out of 26 midsize SUVs. It has cheaper ownership costs than the national average due to the $489 average annual repair cost. When compared to all other vehicles, the frequency and severity of repairs are both about average.
Cost
A Toyota Highlander’s total yearly cost for repairs and maintenance is $489, whereas the average for midsize SUVs is $573 and the average for all vehicle models is $652.
the typical annual sum for unplanned maintenance and repairs for all model years of a car. A vehicle’s greater average cost alone does not imply that it is less dependable. For instance, your car’s parts and labor may be pricey, especially if it’s a European luxury model, but if there are few serious problems and frequent service visits on average each year, that’s a sign of a dependable vehicle.
The typical annual frequency at which a vehicle is taken in for unplanned maintenance and repairs. This metric is produced by monitoring millions of distinctive automobiles over a number of years to ascertain the typical yearly visits for each make and model. Controls were included to prevent small, routine shop visits, such those for oil changes.
The severity element of dependability calculates the likelihood that a repair will cause a significant problem. The cost of a repair is assessed to be excessively expensive given the unscheduled nature of the repair if it is three times the average annual repair cost for all models. Due to their more expensive labor and component expenses, premium and luxury brands have a higher barrier.
Frequency
Owners of Toyota Highlander vehicles must take them into a shop for unplanned repairs on average 0.3 times year, as opposed to 0.4 times on average for medium SUVs and 0.4 times for all vehicle models.
Severity
The Toyota Highlander has a 13 percent chance of needing a significant or catastrophic repair, compared to a midsize SUV average of 13 percent and a nationwide average of 12 percent.
