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.

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, do you require 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.
Do premium fuels have better fuel economy?
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.
Is premium fuel actually worthwhile?
Most vehicles accept standard, but few only accept premium. There have been some erroneous purchases made at the pump because it is not quite clear how these two kinds of gasoline differ from one another. Continue reading if you’re unsure about what to put in your car’s gas tank. You could end up saving money.
So, what’s the difference between premium and regular gas?
In most areas, regular gas has an octane rating of 87, whereas premium gas frequently has a higher rating of 91 or 93. Higher octane fuel can withstand greater compression before detonating. In essence, the risk that a detonation occurs at the wrong time decreases with increasing octane grade. This event will occasionally probably not cause any damage to your car. However, if it occurs frequently, it could hasten the performance deterioration of your engine.
For optimum performance and fuel economy, engines with high compression ratios or turbochargers frequently need the high octane gasoline found in premium gas. The majority of vehicles on the road today, however, are designed to run on ordinary gas.
If your car doesn’t require premium, fill up with regular.
Why spend a lot of money on something you don’t require? Premium petrol costs around 50 cents more per gallon than regular gas and doesn’t affect vehicles that can’t use it in any way. The Federal Trade Commission warns consumers that, “In most circumstances, using gasoline with a higher octane rating than your owner’s manual suggests delivers absolutely no benefit. It won’t improve the efficiency, performance, speed, or mileage of your vehicle.
In order to clean your engine and improve performance, the detergent additives in your gasoline are significantly more significant than the octane rating. Every shop offers a unique mixture of additives that are applied to all grades. For instance, Chevron’s Techron is available in both their normal and premium gas.
Some people hold themselves to a higher standard when it comes to additives. The Top Tier Gasoline standard, which requires a higher-percentage of detergent additive than the EPA minimum criteria, was developed with the assistance of BMW, General Motors, Honda, Toyota, Volkswagen, and Audi. They contend that lesser detergent additive concentrations may cause greater deposits to form on engine parts like the intake valves and fuel injectors. As a result, emissions may rise and engine performance may be affected. j
If your car requires premium, fill up with premium.
For high compression ratio engines to operate at their intended levels of performance, fuel economy, and emissions, higher octane gasoline is often required. Don’t cut corners if your car requires premium fuel. Your automobile will be less powerful and fuel-efficient even though you might save money on gas. When driving a car with a turbocharged engine, this can significantly alter the performance.
What if premium gas is needed but isn’t readily available? While newer automobiles have sensors that are watched by the engine’s computer to assist prevent knock and, by extension, engine damage, older ones may be subject to engine knock when driving on low octane fuel. As the engine’s computer can alter the ignition timing, your car will probably be alright running on normal occasionally, but we don’t advise doing so frequently.
A modern vehicle’s ECU (Electronic Control Unit) can take differing octane levels into account and adjust when you use a lower grade of fuel than what is advised or required. Your horsepower and MPG are likely to decrease as CO2 emissions increase. Gas may be cheaper, but in this case, you get what you pay for.
If your car only recommends premium, the choice is yours.
The Ford F-150 and Mazda MX-5 Miata are two examples of automobiles for which automakers advise premium fuels but do not mandate it. According to AAA’s research, these vehicles’ performance and fuel efficiency somewhat improved while using premium gas. If you drive a luxury or performance car, premium gas might assist highlight your car’s desired qualities.
However, you can safely run on ordinary if your owner’s handbook specifies “premium fuel suggested.” Commuters trying to get from point A to point b might not notice or care depending on what and how you drive. It all comes down to personal preference in the end. Your rules, your car.
Need some fuel-friendly vehicle choices?
It can be challenging to compare all the vehicles that are now on the market with rising gas prices. Check out these vehicles that use little to no gasoline to make things simpler! Check out these gas-saving suggestions as well.
Does premium fuel make your engine cleaner?
It’s a myth, my dear buddies (or perhaps old car guys tale would be more apt). This rumor has the tenacity of a cockroach or a garden weed. Every time someone decides to treat their car to petrol, this message appears: “No ordinary gas for you today, car! The nice stuff is what you’re receiving today.
Hogwash. You should follow the instructions exactly. Do you realize why everything you heard from someone else is false? as they have never produced an automobile.
If it was designed to run on ordinary gas, then no. Your car won’t operate any more smoothly, energetically, cheerily, or efficiently. The engine’s combustion process was carefully constructed by the maker using a lot of science. No more than eating a carrot enables you to lift a bank vault, switching to a different gasoline blend won’t miraculously give your car greater power.
Nope. All types of gasregular, plus, and premiumcome with detergents to reduce the buildup of carbon deposits in your engine. The special abilities for cleaning the engine are not included with Plus and Premium. You would be better off having your engine serviced if you were interested in cleaning it out.
No. Regular gas and premium gas both contain the same amount of energy. Premium gas is unique in that it can endure higher pressure levels without combusting. High-performance engines apply more pressure to the fuel in order to produce more power. Therefore, premium gas isn’t necessarily more potent. The engine it’s going into was built to produce more power, that’s why.
Yes. Do what your owner’s handbook directs. It’s alluring to believe that spending more money at the pump will somehow benefit your car, but we’re afraid this is a fantasy. As we previously stated, have your car inspected by a manufacturer-trained automotive specialist if you truly want to increase its lifespan. The greatest method to ensure that your car runs as effectively and as long as possible is to do that.
