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. Most Toyota vehicles have an electronic control module calibrated to 87 octane. Many individuals mistakenly think that choosing better grade fuel can enhance your car’s performance.

Is it okay to fill a Corolla with premium gas?
There is no need to use premium fuel because your car was designed to run on standard petrol. With vehicles constructed for regular gas, premium materials are not used. It merely increases cost, that’s all.
How much petrol should I put in my Corolla?
So, does Toyota have a preferred gas type? Regular or mid-grade fuel or fuel with a Toyota octane rating of either 87 or 89 yields the best performance from the majority of vehicles in the lineup.
Do Toyotas accept 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.
Can I fill up my 2021 Toyota Corolla with premium gas?
There are no Toyota models available right now that need high-octane fuel. Your car needs normal fuel with a minimum octane value of 87, which is standard pump gas.
What happens if I fill an ordinary car with premium gas?
Engine knock is reduced by using premium gas, which has a higher octane rating. According to The Drive, 87 octane will almost immediately start the engine banging in older vehicles that need premium fuel.
Does using premium fuel increase mileage?
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.
What automobiles exclusively need premium fuel?
How much more will you pay to fill up a car that calls for premium fuel? For instance, the 1.5-liter or 2.0-liter turbocharged four-cylinder engines are options for the midsize Chevrolet Malibu vehicle. The smaller of them is rated at 32 mpg, has a gearless CVT transmission, produces 163 horsepower, and uses regular-grade petrol. The larger turbo-four, which has a nine-speed automatic transmission and a peppier 250 horsepower, only gets 26 mpg and costs more.
It may be unfair to compare apples and oranges, but the EPA estimates that purchasing the regular-fuel-powered Malibu will result in fuel savings of $750 year when driven 15,000 miles in total in city and on the highway at rates in effect as of May 1. Over the course of a five-year ownership tenure, that will cost an additional $3,750 in operating expenses, and when gas prices eventually start to climb, that amount may well increase.

What happens if 87 octane fuel is used in a 93 octane vehicle?
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.
Answer
Yes, you may use E10 fuel in your Corolla. All Corollas produced before July 1994 are ineligible, while cars produced after that date are, thanks to the presence of ethanol-compatible parts including fuel lines and the interior of the gas tank. You have the option to use E10 or not. Although it would be worthwhile to compare a tank of E10 to the premium fuel you have been using and see if there is any significant difference in performance or economy, Toyota maintains the car is compatible, so you shouldn’t have any mechanical difficulties. You can then decide on the advantages.
