Present (Hybrid)
With an octane rating of 8790, the 2.5L hybrid gasoline engine in the 2021present Toyota Sienna is made to run on premium unleaded regular fuel. The engine in the current Sienna is also tuned for fuel with an octane rating of 9192.
The 3.5L V6 gasoline engine that powered the Toyota Sienna from 2010 to 2019 was designed to run best on premium unleaded fuel with an octane rating of 87. For this vehicle, premium gas is not advised because it would not provide any significant benefits over regular gas.
However, premium gasoline with an octane level of 91 is also suitable with the Sienna.
From 2003 through 2010 versions, the Toyota Sienna used a 3.3L V6 gasoline engine that was built to run on premium unleaded fuel with an octane rating of 87.
It is not advisable to use premium gas with this car because it does not profit from it. On the other side, the Sienna can run on premium gas with a 91 octane rating.
The 3.0L V6 gasoline engine that powered the Toyota Sienna from 1997 to 2003 was designed to operate with premium unleaded fuel with an octane rating of 87. For this vehicle, premium gas is not advised because it would not provide any significant benefits over regular gas.
Does Toyota require premium gas?
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.
What Toyota Sienna mileage qualifies as high?
Numerous Sienna owners attest to regularly witnessing odometer readings of 100,000, 200,000, 250,000, and even 300,000 in their vehicles. For instance, owners of vehicles characterized as “still running way strong” on this Sienna forum report odometers as high as 364,514 miles. Owners of more recent 2015 Toyota Sienna cars had 200,000 miles on their odometers, according to other reports on Edmunds.
If you purchase a Toyota Sienna minivan, it would seem reasonable to assume that it will easily reach 100,000 kilometers. A Sienna should be able to travel 200,000 miles with regular and appropriate maintenance. This van is built to last a long time.
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.
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.
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.
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.

Which minivan is the most durable?
The Toyota Avalon leads large sedans in this category, with 2.6 percent of them having surpassed 200,000 miles. The Honda Accord is the leader in the midsize vehicle segment, followed by the Honda Civic in the compact car segment, the Audi TT in the sports car segment, and the Honda Odyssey in the minivan segment.
4.2 percent of all Toyota Highlander Hybrid crossover SUVs are still going strong after logging 200,000 miles, contrary to some drivers’ beliefs that gas/electric hybrids and fully electric vehicles will have shorter-than-average usable lives due to depleted batteries. The hybrid Toyota Prius (2.0%) and the fully electric Tesla Model S are also praised for their durability (2.3 percent). The latter groups do have one restriction, though. “Ly says there aren’t many models that have been on the road long enough to reach the 200,000-mile milestone because many hybrid and electric cars didn’t enter the market until recently.
The analysis also identified the automakers whose products are most likely to last a long time. The top two obvios selections for the industry’s above-average nameplates in this regard are Toyota (with seven of the top 15 models) and Honda. GMC, Chevrolet, and Ford are three domestically produced brands that round out the top five. “According to Ly, American SUVs and pickup trucks tend to endure the longest, which helps explain why they are ranked above average on this list.
