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.
Toyota does not accept unleaded fuel.
A 2021 Toyota RAV4 will only run on standard unleaded fuel with an octane rating of 87 or above. Using fuel with an octane rating less than 87 may cause engine knocking, which could seriously harm your engine in the future.
Along with using at least octane rating 87 gasoline, the following fuels should be avoided:
- Avoid using MMT (Methylcyclopentadienyl Manganese Tricarbonyl) gasoline in your RAV4 since it may result in emission problems.
- Detergent-free gas: Since detergents keep your car’s fuel system clean and maintained, using gas without them could lead to buildup over time. Due of this, you should try to fill up at reputable gas stations that make sure to only add a small amount of detergent to their fuel. Try to stay away from stores like BP, Amoco, Walmart, and 7-Eleven if you can because they might not have detergent.
You should hunt for affordable auto insurance to protect your vehicle and your finances now that you are aware of the fuel types your 2012 Toyota RAV4 will accept and which ones you should avoid. With

What type of fuel does a Toyota Camry use in 2021?
Regular gasoline is required to operate a 2021 Toyota Camry efficiently. The more expensive fuel alternative does not improve the performance of your car, but it does not harm it if you put it in the tank.
A Toyota Highlander: Does it need premium fuel?
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.
Can a Toyota Corolla run on 88 RON?
Use Unleaded 88 in any gasoline or flex fuel vehicle manufactured in 2001 or later. The usage of this gasoline in all light-duty cars produced in 2001 and later has been evaluated and certified by the U.S. Environmental Protection Agency (EPA). The Energy Department test program included 86 vehicles that were each driven for up to 120,000 miles while following an EPA-defined test cycle that was industry-standard (called the Standard Road Cycle). The Energy Department data that resulted from this testing indicated no statistically significant loss of vehicle performance and was allowed for use all year round.
Is it acceptable to use normal gas with premium?
Does it really matter if I use premium fuel? Could your engine be harmed or lose its warranty if you don’t use premium fuel? The solutions might surprise you. Before your next trip to the gas station, continue reading to learn the truth.
What If the Manufacturer Requires It?
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.
Differences Between Premium and Regular Gas
Similar to ordinary unleaded fuel is premium gas. Both are highly flammable and made from crude oil. But one of the biggest variations is that premium fuel has a higher octane rating. The majority of premium fuel has an octane rating of 90 or above. When it comes to supplying automobiles with power while avoiding knocking, octane is crucial. Pre-ignition, an explosion that results from gasoline and air igniting before they should, produces a knocking sound. The term “octane” describes how effectively a fuel can withstand pre-ignition. Premium gasoline is less likely to pre-ignite or knock when it has an octane rating of 90 or higher. Additionally, premium fuel has additives and detergents that make engines run cleaner. Less pollution is produced as a result of the additives and detergents.
The Bottom Line
Modern engines’ computers can, up to a degree, modify the ignition system to work with lower-octane fuel. Fuel efficiency and acceleration are likely to suffer at least significantly when using normal gas. Regular is more likely to detonate because it has a lower octane rating. Long-term or under extreme loads, burning regular in an engine made for premium can induce engine knock, which can harm the pistons, valves, or spark plugs. You might not hear knocking because of the knock sensors and the capacity of the automobile to delay the spark timing, but that doesn’t mean premium isn’t necessary.
In most premium-designed automobiles, regular can be utilized at least occasionally without consequences, but it’s not a good idea to do it frequently. In conclusion, see the owner’s manual. You should take the engine manufacturer’s word for it if they say premium is needed. Don’t try to buy normal gasoline to save a few cents per gallon. This could result in future costs that are significantly higher.
If you don’t use premium gas, what happens?
Other factors to think about include the possibility of component damage, voiding your warranty, and engine knocking or pinging that sounds like a big woodpecker is under your hood if you don’t use high-octane fuel in your premium vehicle. Ouch.
What occurs if I fill up with normal gas rather than premium?
For an automobile whose engine requires premium fuel, the situation is different. In an emergency, the automobile will run on standard fuel, but you shouldn’t do it frequently. The lower octane of the fuel may cause higher exhaust-gas temperatures and potential knocking, both of which may eventually be harmful to the engine’s health.
