E20 fuel or E20 petrol is the combination of petrol and ethanol in the ratio of 4:1. It means 80% of the E20 fuel is petrol and the remaining 20% is ethanol. Irrespective of the growing concern over the impact of E20 fuel on the vehicles, especially the engine parts, the government is keen on its nationwide implementation.
There are several reasons for it. The first reason is that the E20 petrol is more sustainable as it burns cleaner and reduces the carbon emissions and smoke. Also, the higher percentage of ethanol in petrol means fewer crude oil imports that burden the nation’s economy. Also, increased ethanol demands will support the local ethanol producing companies which shall also strengthen the economy to some extent.
However, ethanol is a solvent with hygroscopic properties i.e. ability to attract moisture from the surrounding air. This creates concern in the mind of vehicle owners regarding their vehicle’s performance, maintenance, fuel-efficiency, and warranty. Luckily, most car brands have upgraded their vehicles to comply with the BS6 norms. Hyundai was one of the earliest brands to understand this and started making E20 complaint cars in 2023. More details on the E20 compatible Hyundai cars and the impact of E20 on their warranty, performance, and maintenance are discussed in the below sections.
What is E20 Fuel?
E20 fuel is a blend of ethanol and petrol. The concentration of petrol is higher (around 80%) whereas the concentration of Ethanol is up to 20% in this blend. Ethanol is a biofuel meaning it can be easily produced from plant waste. Its higher octane rating prevents engine knock but it produces less energy as compared to petrol. This forces your vehicle to produce more power for the same level of acceleration or speed. The specific properties and behaviour of E20 petrol have forced the car brands to redesign the fuel lines, Engine Control Units (ECUs), and some other parts of their models.

How to Check if Your Hyundai Car is E20-Compatible?
Firstly, read the car owner’s manual properly. Under the fuel section, it will be mentioned whether the car is E20 petrol compatible or not. Or else, it will be written that 20% ethanol blend is safe for your car.
The sticker on the fuel lid may have the E20 sticker or label. If it’s there it means that your car is E20 compliant and no further investigation is needed. You can also check with the dealer if you don’t find any E20 sticker on the fuel lid. The details regarding the E20 compatible models will also be available on the official site of Hyundai.
Impact of E20 on Hyundai Cars
Let’s check the impact of E20 fuel on the various aspects of Hyundai cars:
Mileage
E20 produces around 30 to 35% less energy than petrol. So, you have to keep pressing the accelerator harder to achieve the intended speed. This makes the engine work harder which ultimately affects the mileage of your car. A decrease in mileage ranging from 5 to 7% can be observed in this case. This difference might seem to be negligible but may impact your savings in the long run.
Performance
Car brands like Hyundai have adjusted their engine and ECU to fill the gap of power delivery and performance. Also, the high octane rating of E20 fuel tackles the engine knock better.
Engine Wear
The engine of older cars and variants may wear faster due to the E20 fuel. This happens because ethanol attracts water that eventually separates out from the fuel. This leads to moisture deposits in the fuel tank, filter, and other engine parts which expedites the rusting process. Also, the solvent properties of ethanol leads to rust deposits in the fuel filters and gaskets further accelerating the rusting process.
The E20 compliant cars from Hyundai do not face this problem because they have integrated ethanol-resistant materials in their fuel pumps, lines, and seals. This ensures the safety of your engine and vehicle too.
Resale Value
As more and more cars are getting E20 compatible, the resale value of non-compliant E20 cars shall get affected. However, this won’t affect the resale value of cars compatible with the E20 fuel. In fact, those who purchase the E20 compatible cars can expect a higher resale value while selling their vehicles in the future.
Summary
We hope you’ve understood the difference between E20 compliant and non-compliant cars. Hyundai is one of the leading brands when it comes to launching E20 compatible cars. Most of their car models such as Creta, Venue, Verna, i20, Exter, and Grand i10 Nios released after the first quarter of 2023 are E20 compatible. Therefore, you don’t have to worry if you own one of these models.
