Fuel Requirements Based on Engine Type
Furthermore, we have to clarify that the use of premium gasoline (91-octane or higher) is not necessary for the Hyundai Ioniq. People often believe that premium gasoline will keep the engine cleaner and perform better.
This is only the case for engines that are designed to make use of premium gasoline. Furthermore, premium gasoline is most often used in sports cars or vehicles that tow heavy loads. Since the Ioniq does not fall into either of these categories, it´s best to take regular gasoline whenever you can.
Also, keep in mind that going below 87-octane is strictly advised against and will result in engine problems (more on that later).
What Type of Gasoline Can A Hyundai Ioniq Take?
Gasoline/Oxygenated Blends or E-85
First of all, it´s important to clarify that methanol should never be used in any Hyundai Ioniq. Methanol is too much of a corrosive substance, and the internals of the Ioniq aren´t made to deal with this kind of fuel in any percentage.
On the other hand, ethanol can be used. All Ioniqs with a gasoline engine can take gasoline with a maximum percentage of 15% ethanol. This means both E10 and E15 are fine to use. However, E30, E50, and E85 (which is also referred to as flex-fuel) cannot be used, and doing so will result in damage that´s not covered by any form of warranty.
Addition of Cleaning Agents
If you can´t find TOP TIER gasoline in your area, then Hyundai recommends using a bottle of its own additive every 7,500 miles. You can find the additive that´s recommended for your Ioniq at a local Hyundai dealership.
What If The Engine Makes A Knocking Noise?
What’s The Gas Mileage Of The Hyundai Ioniq?
One of the main selling points of the Hyundai Ioniq is that all versions of this car are incredibly fuel efficient. That´s because all versions make use of an electric drivetrain in one way or another. Below, you´ll first see the MPG for the hybrid versions of the Ioniq.
|Drivetrain||Combined MPG||City MPG||Highway MPG|
|1.6L (Hybrid, Blue version)||59||58||60|
|1.6L (Hybrid, Limited version)||55||54||57|
However, things get even better when we look at the PHEV and the EV versions:
|Drivetrain||Electric only MPGe||Gasoline only MPG|
What Is The Tank Size Of A Hyundai Ioniq?
All Hyundai Ioniqs with a gasoline engine manufactured between 2017 – 2022 have a fuel tank capacity of 11.9 gallons or 45 liters.
In conclusion, the Hyundai Ioniq, produced from 2017 to 2022, thrives on regular unleaded gasoline with an octane rating of 87 or above. Whether you own a hybrid or plug-in version, the fuel requirements remain consistent. To ensure optimal performance and longevity for your Ioniq, it’s imperative to use the recommended fuel. We delved into the specifics of its fuel compatibility, tank capacity, and mileage, offering you a comprehensive understanding of the Ioniq’s fuel dynamics. Always refer to your owner’s manual for precise information and safe driving!
