Which fuel is best for a Toyota Yaris?

Regular unleaded gasoline that meets your region’s minimum octane standard is the best choice for most Toyota Yaris models. Premium fuel is not required and is unlikely to improve performance, even in hybrid versions.


The question of fuel for a Toyota Yaris varies by drivetrain, region, and model year. The Yaris is offered as a conventional petrol hatchback and as a hybrid, and fuel compatibility can differ for markets around the world. This guide explains the general rules, region-specific notes, and practical tips to keep your Yaris running efficiently.


Conventional petrol Yaris


Before the list: The standard Yaris engine lineup in many markets runs on unleaded petrol. The key factors are the octane rating and compatibility with ethanol blends. The following guidelines summarize common practice, but always follow your owner’s manual for your exact model year and market.



  • Regular unleaded gasoline is typically suitable for most petrol Yaris engines. In the United States and many other regions, this means the minimum octane grade required by the manual (often 87 AKI or equivalent in regional charts).

  • Premium gasoline (higher octane) is not usually required for everyday driving and does not guarantee noticeable gains in fuel economy or acceleration for standard Yaris engines. It may offer marginal benefits in certain operating conditions, but it isn’t a universal upgrade.

  • Ethyl alcohol blends: Most Yaris models tolerate ethanol-blended fuels such as E10 (10% ethanol) in many regions. Always verify compatibility in the owner’s manual or on the fuel cap label; higher ethanol blends (like E15 or E85) are generally not recommended unless the manual explicitly states support for your engine.

  • Diesel and other non-petrol fuels are not suitable for conventional petrol Yaris engines. Do not use diesel, biodiesel, or other alternative fuels unless the vehicle is specifically designed for them.


Conclusion: For a typical petrol Yaris, use the regular unleaded fuel that matches your region’s octane specification. Premium fuel is optional and usually unnecessary for daily driving.


Yaris Hybrid fuel guidance


Before the list: The Yaris Hybrid combines a petrol engine with electric propulsion. While fueling patterns are similar to the petrol version, the octane and ethanol guidelines can differ by market. Always consult the owner’s manual for your exact hybrid model and year.



  • Regular unleaded gasoline is commonly recommended for Yaris Hybrid models. In many markets, this means the same minimum octane as the petrol version, with premium fuel not required for routine driving.

  • Regional differences apply: in Europe, many hybrid Toyotas are specified to use petrol with a 95 RON or higher rating; in the United States, 87 octane is commonly acceptable. Check your manual to confirm the exact requirement for your vehicle.

  • Fuel ethanol content: Yaris Hybrids generally tolerate E10 in many regions; avoid E85 unless the manual explicitly states that your model supports flex-fuel or higher-ethanol fuels.

  • Octane and performance: Higher-octane fuel rarely yields a meaningful efficiency or acceleration advantage for the Yaris Hybrid. Consistently high-octane fuel should not be viewed as a substitute for proper maintenance and driving style.


Conclusion: The hybrid version follows the regional octane and ethanol guidance in the manual. Premium fuel is not a universal requirement and is often not necessary for everyday driving.


Region-specific notes and tips


Europe and UK


Europe often recommends unleaded petrol with a minimum octane around 95 RON for many Yaris variants, including hybrids. E10 is widely available and suitable for most modern Toyotas. Always check the exact fuel specification printed in the vehicle’s manual or on the fuel-filler label for your specific year and engine version.


Conclusion: In Europe, plan for a higher octane minimum in many cases, but verify your exact model’s requirements in the owner’s manual.


United States and Canada


In North America, regular unleaded gasoline (87 octane) is typically adequate for most Yaris engines, including the Hybrid. Some drivers may choose premium for perceived performance in extreme heat or heavy-use scenarios, but it is not required by the manufacturer for normal operation.


Conclusion: Use the manual-specified octane in your region; for most daily driving, regular grade is appropriate.


Other regions (Asia, Africa, Latin America)


Fuel standards vary by country, but modern Yaris models are designed to work with commonly available fuels in their markets. Most regions support E10 and other standard blends; always confirm octane and ethanol compatibility in the owner’s manual or at the fuel label on the filler door.


Conclusion: Follow local specifications and the manual to ensure compatibility and optimal performance.


Tips to get the best efficiency from your Yaris


Before the list: Fuel type is important, but driving habits and maintenance play a major role in efficiency. Here are practical steps to maximize miles per gallon and reduce wear.



  • Keep tires inflated to the recommended pressure to reduce rolling resistance and improve fuel economy.

  • Drive smoothly: accelerate gradually, anticipate stops, and use cruise control on highways when safe.

  • Follow the maintenance schedule for the engine and hybrid components to maintain efficiency and performance.

  • Choose reputable gasoline brands and, where possible, top-tier fuels for cleaner deposits and better engine cleanliness.

  • Be mindful of ethanol content and refuel with the appropriate blend for your region as indicated in the manual or on the fuel label.


Conclusion: Fuel choice matters, but consistent maintenance and mindful driving have a larger impact on real-world efficiency.


Summary


The Toyota Yaris is designed to run efficiently on the appropriate unleaded gasoline specified for your model year and market. In most regions, regular unleaded fuel is sufficient for both petrol and hybrid versions, with premium fuel offering limited to no decisive benefits for everyday use. Ethanol blends such as E10 are commonly supported, but higher-ethanol fuels should only be used if your manual confirms compatibility. Always refer to the vehicle’s owner’s manual and fuel-label guidance for your exact model, and pair the right fuel with good driving habits and regular maintenance for best results.

Should I use 87 or 89 gas?


Your car will run just fine. All modern cars can run 87,89,91,93. It's suggested that for maximum power that you use 93. If you're not at a track day event and just daily commuting 87 will serve you well. All modern cars are equipped with knock sensors to prevent engine damage from running lower octane fuel.



What happens if I put 93 instead of 91?


Putting 93 octane instead of 91 in a car is generally fine, and you will likely not notice a difference, as the engine's computer will adjust to the higher octane. In some high-performance or tuned vehicles, using 93 may provide a slight increase in performance or fuel economy, though this is not guaranteed. You may be wasting money, as higher octane fuel is more expensive and not needed if your car is not designed for it. 
What to expect

  • No change: Most modern cars are designed to automatically adjust to the higher octane fuel, so you probably won't notice any difference in performance or fuel economy. 
  • Potential for slight improvement: In some specific cases, particularly in high-performance or turbocharged engines, the higher octane can provide a slight increase in power or fuel efficiency. 
  • No harm to your engine: Using a higher octane fuel than recommended is not harmful to your engine. 
  • Higher cost: You will pay more at the pump for a fuel you don't need. 

What to do if your car requires 91 octane
  • Check your owner's manual to confirm the minimum octane requirement for your vehicle. 
  • If your car is not a high-performance model and requires 91 octane, there is no benefit to using 93 octane. You can simply use 91 octane and save money. 
  • You can continue to use 91 octane for all future fill-ups. 



What brand of gas does Toyota recommend?


Top Tier Detergent Gasolines
Toyota recommends the use of “Top Tier Detergent Gasolines,” where available. Gasoline brands with this designation meet new, voluntary standards and have demonstrated their ability to keep engines clean through a series of demanding tests.



What type of gas does a Toyota Yaris take?


The Toyota Yaris uses regular unleaded gasoline (87 octane). You do not need premium fuel, as higher octane gas provides no performance benefit and using it is a waste of money. Newer Yaris models, like the Yaris Cross, use a hybrid system and have a fuel tank for unleaded petrol. 

  • Fuel type: Use regular unleaded gasoline with an 87 octane rating. 
  • Octane: Higher octane fuels are not recommended for the standard Yaris and can be a waste of money, as the engine is designed for 87 octane. 
  • Hybrid models: Hybrid versions of the Yaris use a fuel tank for unleaded petrol but also have an electric motor for assistance. 
  • Check your manual: Always check your specific Yaris's owner's manual or fuel cap for the most accurate recommendation.
