Types Of Gas A Toyota Yaris Takes (Explained)

On this blog, we extensively research your queries about various automobiles. Today, we’ll look at the Toyota Yaris and see what kind of gasoline it needs. To find the answer, we looked through all the Yaris’s owner’s manuals since 2006. Here is a quick response:

All generations of the Toyota Yaris manufactured from 2006 onwards and sold in the North-American market take regular unleaded gasoline with an octane rating of 87.

Simple fuel requirements are typical for Toyota vehicles whether you’re talking about a gas-powered SUV like the 4Runner or a compact hybrid like the Corolla it’s usually just octane 87 that’s required.

Using the right fuel is essential to get the best performance of your car. However, this doesn’t tell the whole story. Below, we will detail what kind of gasoline should and shouldn’t be used in the Yaris. Furthermore, we´ll discuss this car’s fuel tank capacity and gas mileage. Read on!

Fuel Requirements Based on Engine Type

All generations of the Toyota Yaris manufactured from 2006 onwards have 87 octane gasoline recommended. Gasoline with an octane rating higher than 87 is possible; however, using premium gasoline (91 octane or higher) is unnecessary for your Yaris.

That’s something we’ve seen in most Toyota vehicles that we’ve looked at whether we’re talking about fueling up hybrids like the Highlander and Prius or a minivan like the Sienna 87 octane is typically all you need.

Many people believe that premium gasoline will improve the lifespan of the engine as well as improve performance. However, this is not the case for the Yaris, and typically it´s only wise to use premium gasoline when the manufacturer recommends this. In the case of the Yaris, it will only lead to a higher bill.

What Type of Gasoline Can A Toyota Yaris Take?

Furthermore, different types of gasoline are and aren´t appropriate to use in your Yaris. Below, we´ve outlined all these types so you know exactly what can and can´t be used.

Reformulated Gasoline

First, we have to talk about the use of reformulated gasoline. This is a type of gasoline that burns cleaner than non-reformulated gasoline. For this reason, it´s mandatory to use in some regions of the United States. Toyota Yaris can run on reformulated gasoline just fine. If you have the choice between these two types of gasoline, it´s best to go with reformulated gasoline since it doesn´t cost anything extra but does help the environment and the air quality in your region.

Gasoline/Oxygenated Blends or E-85

Secondly, there´re oxygenated blends of gasoline. Oxygenated gasoline blends typically contain ethanol or methanol, both of which are bio-sources of gasoline. Using both of these substances comes with strict rules that must be followed.

First, methanol cannot be used in any model year of the Yaris. Methanol is a very corrosive substance that will damage the internals of your engine and fuel system.

On the other hand, ethanol can be used, and it´s pretty common to do so. All model years made until 2020 can take gasoline with a maximum percentage of 10% ethanol. For this reason, the Yaris cannot take E15 (15% ethanol). Also, no model year of the Yaris has flex-fuel capabilities (which is also referred to as E85 and contains 51-83% ethanol in the United States).

Addition of Cleaning Agents

The use of cleaning agents or octane boosters is something that you´ll hear about from time to time. Therefore, it´s good to know that Toyota recommends against the use of these cleaning agents. This is because cleaning agents often use silicones or metallics that will damage your engine’s fuel system and the internals.

Instead, Toyota recommends the use of TOP TIER gasoline. TOP TIER retailers sell this type of gasoline. This group of retailers is an alliance that provides gasoline that contains all the suitable cleaning agents your car needs and in a larger quantity than what´s stated by law. You can find a TOP TIER gasoline retailer at

What If The Engine Makes A Knocking Noise?

If you hear a knocking noise coming from your engine, then it´s most likely the case you´ve used gasoline with a lower than recommended octane rating.

You must stop the vehicle immediately and call your dealer or mechanic if you hear a loud knocking noise from your engine, especially right after refilling. Your vehicle needs to be towed away and drained from its gasoline, and your fuel filter will also need to be replaced.

Continuing to drive Toyota cars, like the Toyota Tacoma, Sequoia, and all the other models, with a loud knocking noise will result in irreparable damage that is not covered by any warranty.

What’s The Gas Mileage Of The Toyota Yaris?

One thing is for sure, and that´s the fact that the Yaris has always been able to get great MPGs. Throughout the generations, the Yaris has had the same engine in the United States, and this is a 1.5L 4-cylinder engine.

Between 2007 – 2012 this engine got a combined MPG of 32, a city MPG of 29, and a highway MPG of 36. From 2013 onwards, the MPGs slightly improved with a combined MPG of 35, a city MPG of 32, and a highway MPG of 40.

What Is The Tank Size Of Toyota Yaris?

Toyota Yaris that were manufactured between 2006 – 2016 have a fuel tank capacity of 11.1 US gallons or 42 liters. The Yaris was updated in 2017, after which all subsequent models had a fuel tank capacity of 11.6 US gallons or 44 liters.
