Can Toyota Aygo Use E10 Fuel? (Let’s Find Out)

Whenever you drive your car, you are concerned about your auto’s health.

An important determinant of the longevity of your engine is the type of gas that is used on the car.

In this article, I will tell you what type of fuel best suits your Aygo car and explain the reasons why. 

A Toyota Aygo can use E10 because the engine of the Aygo is compatible with it. E10 fuel is cleared for use in all cars made after 2000. You may find some records dating as far back as 1998; whichever the case, your Toyota Aygo was made in 2005. Then there is nothing for you to worry about.

Is E10 Fuel Good for Toyota Aygo?

Can Toyota Aygo Use E10 Fuel?

The E10 is good for the Aygos engine. It works by burning the E10 efficiently to generate the car’s energy.

The E10 fuel is a combination of gasoline and ethanol.

The gasoline is used to initiate the energy generated, while the ethanol is used to sustain and maintain that energy generated. 

What is E10 Fuel?

E10 is a fuel with a unique proportional blend of ethanol and gasoline.

The E stands for Ethanol, and the number attached is the amount in which ethanol is present in percentage.

The ethanol in fuel is in an anhydrous form and mixed with gasoline, used in internal combustion engines.

Internal combustion engines are designed for automobiles, light-duty trucks, motorcycles, and most model petrol engines.

Though E10 fuels are relatively new, they are compatible with these engines without modifications. They are compatible with Toyota Hybrid Alphard & Toyota Prius as well.

The reason is that it is produced from materials with which these engines are conversant.

The ethanol present in E10 is anhydrous in form; this implies that the ethanol does not contain water. 

An octane means that the contents of the gasoline have branched chains in its chemical composition.

The longer the chain, the higher the octane rating. So, an octane rating is simply an index of the fuel’s resistance to burning out too early inside the engine.

E10 has a minimum octane rating of 91 and may vary up to 95 depending on the production technique employed. 

The significant difference in most fuels is the composition of ethanol. The ethanol is present in varying quantities or nonexistent in other gas types.

Ethanol is a chemical compound popularly referred to as alcohol.

This alcohol is not different in chemical composition from the one you know which you consume.

Ethanol is alcohol obtained from green sources like sugars, grains, and wood. These agricultural substances are subjected to a process of fermentation and distillation.

The fuel from ethanol powers vehicle petrol engines with energy containing less carbon and therefore marginally less carbon dioxide and better suited for our environment.

Little wonder it is often described as Bioethanol.

Pros and Cons of E10 fuel?

The use of E10 fuel provides some advantages and also exposes the engines to other disadvantages. 

Some advantages of using E10 include:

  • Economical to use
  • Preserving the environment by reducing air pollution
  • Easily accessible to everyone

Some disadvantages of the E10 include:

  • Difficulty starting the car in cold weather
  • Stalling due to vapor lock
  • Corrosion and leakages

Let us now look at these points in tiny detail.

Pros of E10 Fuel

#1. Economical to use

First, E10 fuels are economical because they have a higher octane rating.

This feature allows them to burn slower than other fuels when used in a Liter Turbo Engine like the Aygo.

The slower these fuels burn, the longer they last, and fewer resources are channeled into purchasing fuels.

#2. Environmental preservation

Greenhouse gases can trap sunlight and radiate them to the earth while preventing this heat from leaving the earth’s surface.

An accumulation of these gases produces the greenhouse effect, leading to global warming.

Due to the less carbon present in E10 fuel, fewer greenhouse gases are emitted.

#3. Easily Accessible

A mixture produces E10 fuels of gasoline and substrates widely available in many world regions.

Due to the widespread availability of the substrates, the E10 fuels are easily available.

That is because the mainstream gasoline fuels may only be gotten by regions rich in fossil fuels.

Cons of E 10 Fuel

#1. Difficulty Starting in Extremely Cold Weather

Hot surfaces cause condensation of water vapor. Since it is heavier, this condensed water vapor sinks to the bottom of the tank.

It immediately mixes with the ethanol in the fuel and then prevents the gasoline from entering the engine. 

Furthermore, this condition is usually worsened in cold weather where the water vapor sometimes freezes within the tank.

The gasoline is responsible for igniting the engine, while ethanol takes over in the sustenance of the energy supply to the engine. 

#2. Stalling Due to Vapor Lock

The engine can be stalled as a result of increased temperature.

Ethanol fuels are highly volatile, leading to petrol becoming gaseous when operating in higher temperatures.

The temperature of engines is higher when used for a long period, such as during a long cross-country trip or used in hot weather conditions.

#3. Corrosion and Leaking

E10 fuel causes corrosion to the parts it lubricates. Such corrosion affects the rubber parts, gaskets, seals, metals, and plastics, which causes engine damage.

This damage would predispose the engine to pore spaces previously not present, leading to leakage within the engine. 

Additionally, the corrosion can also dislodge fragmented particles from corrosion, depositing them at distant sites from their origin.

These dislodged particles block other openings in the engine, damaging the engine.

What Fuel Does a Toyota Aygo Use?

Toyota’s Aygo vehicle is powered by petrol. The engines are made to run by burning the energy supplied from the petrol.

The engine found in the Aygo is the 1.0 liters three-cylinder engine rated at 51kw hour.

This functionality describes a Liter engine FSE strictly powered by gasoline fuels. 

Also,  this engine is suitably powered by a wide range of gasoline-powered fuels.

Through a blend of gasoline and ethanol, these fuels include the E5, E7, and E10, well suited for the Aygo engine.

What Happens If You Put E10 in An Unleaded Car?

One-time usage of E10 fuel does not completely damage the engine of an unleaded car.

Your car can still run with the fuel but ensure to return to a more compatible fuel immediately after the tank is emptied or halved.

E10 fuel in an unleaded car is sure to cause damage after prolonged usage.

E10 fuel is an unleaded fuel, which does not contain additives such as lead. Most cars run suitably with e10 fuels, but a few exceptions exist.

Assuming you have e10 fuel momentarily in a car that is not suitable with e10 fuel, then you have only little to worry about.

However, do not make its usage a custom! 


The Toyota Aygo is a car that uses the E10 fuel to power its activities.

The E10 fuel is a blend of gasoline and ethanol in the ratio of 90 to 10 percent.

Though some other fuels exist, Toyota Aygo’s engine is well suited for this fuel. 

The E10 fuel allows for less emission of CO2 because ethanol provides greater energy delivery with the use of moderate fossil fuels.

E10 fuel comes with some disadvantages for the Toyota Aygo car.

These include corrosion of engine parts, difficulty starting in cold weather, and blockage of engine parts.
