E20 fuel is a blended fuel that consists of petrol and ethanol. While petrol is still the larger ingredient contributing to 80% of the blend, ethanol content is now increased from 10 to 20%. Available in India since 2023, the E20 petrol is widely considered as the standard petrol in India now. The government of India launched it as it burned cleaner reducing the carbon emissions and smoke released from the exhaust pipes of the vehicles. Also, it meant better business opportunities to the local ethanol manufacturing companies.
Eventually, the companies also started upgrading their models according to the E20 fuel. Renault has started making fully E20 compliant cars in India since April 2023. However, as per their official announcement, the models released between 2021 to 2023 can also use the E20 petrol. They have recommended avoiding the E20 fuel for cars manufactured before 2021. The details regarding E20 compliant models and how the E20 fuel impacts the performance of the non-compliant and compliant models have been explained in this blog.
What is E20 Fuel?
E20 fuel is a combination of petrol and ethanol. It is named E20 because ethanol comprises 20% of the fuel. Produced from crops such as corn, wheat, maize, or sugarcane, the E20 fuel is 100% plant-based. Due to its higher octane rating, it is ideal for avoiding engine knock issues. Also, it is considered more eco-friendly than the E10 or E5 petrol because it releases lesser carbon emissions and smoke in the environment.

How to Check if Your Renault Car is E20-Compatible?
Some simple ways to check the E20 compliance of your Renault car models are explained below:
- Check the Fuel Flap
The fuel flap of your cars usually contain the stickers such as E10, E5, or E20. If the E20 sticker is present on the fuel flap of your Renault car, it means that it is E20 compliant.
- Read the Owner’s Manual
The owner’s manual of any car contains all the crucial details regarding it. You can also find the details regarding whether the model is E20 compliant or not by going through this manual. These details will be specifically mentioned under the fuel section of your car owner’s manual.
- Official Website
The official website of Renault also contains information regarding the E20 compliance of their cars. Here, you can check whether the specific model you own is compatible with the E20 fuel or not.
- Contact the Dealer
The Renault car dealer can also provide you with the details pertaining to the E20 upgrades. You only have to provide your Vehicle Identification Number (VIN) to them and they will provide all the details of your vehicle including whether it is E20 compatible or not. The E20-resistant materials used in the car models can also be shared with you during this conversation.
Impact of E20 on Renault Cars
The E20 fuel has different kinds of impact on compliant and non-compliant cars. The fuel pipes, injectors, filters, and other parts of compliant cars are made from ethanol-resistant materials. This slows down the wearing and ensures a longer life of engine and engine parts.
As ethanol has a lower energy density, the E20 fuel tends to deliver slightly lower mileage than the fuels that have lower levels of ethanol. Due to the hygroscopic nature of ethanol, it tends to draw moisture from the surroundings. This results in the moisture accumulation in the fuel tanks.
As the engine starts, the higher content of water in the fuel can result in shaky starts and poor power delivery. The unused fuel during idling can enter the engine oil and tend to affect its engine protectant properties. Overall, the higher ethanol content in the E20 fuel results in faster deterioration of parts and reduces performance and fuel-efficiency of your vehicle.
As the E20 compatible cars are prepared to handle these risks, the impact of E20 on such cars is minimal. For instance, the Electronic Control Unit (ECU) in the E20 compatible cars are engineered to balance air-fuel ratio. This leads to a smooth and consistent power delivery and also enhances the overall performance of your car.
Both the E20 compliant and non-compliant cars must be serviced regularly to maintain their optimal performance. Special attention must be given to fuel filters, gaskets, and hoses that get impacted by the E20 fuel the most.
The resale value of the compliant cars will also be higher in the future as compared to the non-compatible Renault car models.
Summary
These were some details on the E20 compatible Renault cars. The owners of Renault cars can opt for the E20 petrol if their vehicle is produced after April 2023. The older vehicles that were compatible with the E10 vehicles might also be technically secure from the harmful effects. However, the models produced before 2021 must avoid the E20 fuel as per the company’s instructions.
