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.

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.

Can 87 and 91 gas be combined?
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.
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.
What kind of fuel is 87 octane?
Measures of gasoline stability are called octane ratings. These rankings are based on the pressure at which a gasoline will spontaneously ignite in an engine under test. Actually, the octane number is the simple average of two distinct octane rating systems. The main differences between research octane rating (RON) and motor octane rating (MOR) are the particulars of the operating conditions. The fuel is more stable the higher the octane number. According to octane rating, retail gas stations in the United States offer three different classes of gasoline:
- Midgrade (the middle range octane fuelgenerally 8990)
- Premium (the highest octane fuelgenerally 9194)
- Regular (the lowest octane fuelgenerally 87)
The octane rating is referenced in all of the names for these kinds of gasoline that certain corporations use, including unleaded, super, and super premium.

The minimum octane rating is shown by the huge number on the yellow octane label on petrol pumps. The octane testing method is identified on the label as (R+M)/2 Method, where R stands for Research Octane Number and M for Motor Octane Number.
The 2,2,4-Trimethylpentane molecule, which is extremely resistant to auto-ignition, is one of the 18 isomers of regular octane (C8H18), which is where the name of the fuel comes from. For testing purposes, this iso-octane has been given the reference value of 100. The 0 octane reference fuel is the exceedingly unstable normal heptane (C7H16) molecule.
The meaning of up to E15 gas
15% ethanol and 85% gasoline are combined to form E15. It has 5% more ethanol in it than E10, the most widely used fuel in the US. While E10 has an octane rating of 87, E15 has a higher octane typical of 88. To emphasize its high octane value, retailers are selling E15 as Unleaded 88.
All automobiles, trucks, and SUVs built in 2001 and later can run on unleaded 88. More than 90% of the cars and trucks on the road today are from these model years. It is the most thoroughly studied fuel in history and has no impact on how well a car drives. Unleaded 88 has been used to drive more than 20 BILLION miles so far, and that number is still rising.
The mileage obtained when using Unleaded 88 and the mileage when using E10 are identical and cannot be distinguished.
The least expensive fuel for vehicles made in 2001 and later is unleaded 88, which normally costs 510 cents less per gallon than E10. Unleaded 88 is about 40 cents more expensive than regular gasoline without ethanol.
Due to lack of testing, unleaded 88 has not been certified by the EPA for use in non-automotive engines such as those found in boats, motorbikes, lawnmowers, and other small or off-road engines. However, E10 is permitted for all on- and off-road engines.
A Toyota Highlander’s range on a single tank of gas
The Toyota Highlander is a multipurpose car that excels at both long road trips and daily commuting. How far can you go, though, before you need to call for assistance when the gas gauge reads empty? Let’s look at what’s underneath.
In a Toyota Highlander, the gas light will often come on when you have 35 to 45 miles left. However, how you drive will determine this. For instance, driving at high speeds and in stop-and-go traffic will use up gas more quickly.
It’s never enjoyable to experience the worry that sets in when the gas light turns on. But don’t worry—in this post, we’ll outline how long it will be before the Toyota Highlander runs out of gas entirely. Continue reading for advice on how to maximize the remaining mileage as well as other information.

What does a car becoming a hybrid mean?
An internal combustion engine and one or more electric motors, which utilise energy stored in batteries, work together to power hybrid electric cars. The battery of a hybrid electric car cannot be charged by plugging it in. Instead, the internal combustion engine and regenerative braking are used to charge the battery. A smaller engine might be possible thanks to the electric motor’s added power. Additionally, the battery can reduce engine idling while stopped and power auxiliary loads. These features work together to improve fuel efficiency without compromising performance. Raise your knowledge of hybrid electric automobiles.
How far can a Highlander Hybrid travel on a single tank of gas?
On a full tank of gas, the Highlander has a driving range of more than 510 miles. The projected EPA mileage for each front-wheel drive model is 29 highway and 21 city. If all-wheel drive is used, the vehicle gets 20 mpg in the city, 27 mpg on the interstate, and 23 mpg overall.
What if I unintentionally entered 87 rather than 91?
When a vehicle manufacturer specifies premium fuel, it’s because the fuel system of that specific vehicle is built to function best with higher octane fuel. In an engine that needs premium fuel, using normal petrol could violate your warranty. That is most likely to occur if repeated use results in severe engine knocking or pinging (premature fuel ignition, also known as detonation), which harms the pistons or other engine components. Other issues, such as worsened engine performance and poorer fuel economy, may result from using the incorrect gasoline.
As an illustration, the following is what GM states about the matter in the owner’s guide for a car that needs premium:
91 or higher posted octane premium unleaded gasoline should be used. If the octane level is below 91, you risk damaging the engine and voiding the warranty on your car. When using gasoline with an octane rating of 91 or above, the engine requires maintenance if loud banging is observed.
Keep in mind that this only applies to engines that demand premium gas. Although some manufacturers advise using premium gas, you can also use standard or mid-grade gas. Usually, they mention that using gas with a lower octane rating could affect performance and fuel efficiency. They advise using premium when that starts to become noticeable, or if engine knock starts to happen.
Do you get higher gas mileage when you use premium fuel?
In luxury and performance automobiles with turbochargers or high-compression engines, premium gas offers a stronger resistance to engine knock, allowing you to reach that horsepower effortlessly. Additionally, premium petrol can improve fuel efficiency, possibly resulting in longer-lasting better gas mileage while lowering pollutants.
Keep in mind that these advantages are only seen in vehicles that actually demand premium fuel, not necessarily in the majority of other vehicles. Note that the definition/label for premium gas can vary from state to state and station to station. Check your owner’s manual to verify what your manufacturer recommends for your individual automobile make and model.
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.
