On this blog, we do a lot of research regarding specific questions about different cars including Genesis like the GV80 model or G70 among others.
Today we’ll look at the Genesis GV70 and answer what kind of gas this car requires. We’ve gone through the owners’ manuals of the 2022 – present-day GV70 to find the answer.
So what type of gas does a Genesis GV70 takes?
Genesis GV70 manufactured from 2021 onward take premium unleaded gasoline with an octane rating of 91. The GV70 is a luxury SUV, therefore, using gasoline with an octane rating lower than 91 will likely damage the fuel system and the engine. If 91 octane is unavailable, please opt for an 93 or 95 octane.
However, that doesn’t tell the whole story. Below we’ll dive deeper into what kind of gas this car takes. We’ll talk about reformulated gasoline, E-85, and gasoline with additives. Should or shouldn’t you use this for the GV70?
We’ll also talk about the fuel mileage of each generation as well as possible knocking noises and so much more. Read on!

Does The Genesis GV70 Need Premium Gasoline?
First, it’s essential to establish what kind of gasoline is genuinely best for the GV70. Since the GV70 is a luxury SUV, Genesis recommends using premium gasoline with an octane rating of 91. This is relatively common for engines placed in luxury cars because they’re more aimed at achieving performance (which is when higher octane gasoline is helpful).
In some cases, carmakers allow these cars to run on gasoline with a lower than recommended octane rating. For example, using 87 – 89 octane when 91 octane is not available. However, for the GV70, nothing about this is mentioned in the owner’s manual.
This typically indicates that using gasoline with an octane rating lower than 91 will result in problems and/or damage to the fuel system and the engine. Therefore, if 91 octane is not available, please opt for a more premium type of gasoline such as 93 or 95 octane.
What Types Of Gasoline Can And Can’t Be Used?
Besides knowing the proper octane levels, there are several other things that you should be aware of concerning the gasoline you use in your GV70. These mainly include different kinds of additives used in the fuel.
Reformulated Gasoline
First, there’s the use of reformulated gasoline compared to non-reformulated gasoline. Reformulated gasoline is gasoline that’s become popular over the past decade because it burns cleaner than its counterpart. For this reason, it has even become mandatory in some areas of the United States.
Therefore, it’s good to know that Genesis recommends reformulated gasoline. Its use won’t negatively affect the engine or decrease its performance. Overall, it’s just a better type of gasoline that should be used whenever available.
Gasoline/Oxygenated Blends Or E-85
Another important aspect we need to discuss is the use of oxygenated blends of gasoline. Oxygenated blends contain chemicals such as ethanol, methanol, or MTBE that aren’t typically found in large quantities in gasoline. However, some types of gasoline may have these chemicals added.
One of the main reasons to add oxygenates to gasoline is because they tend to burn cleaner because they’re made out of biomass. The most common example of this is ethanol, widely used throughout the United States.
Therefore, it’s good to know that the second generation of the Genesis GV70 can take gasoline with a maximum of 15% ethanol, also referred to as E15. This also means that it can take the other popular ethanol blend, E10. On the other hand, it can’t take E30 (30%), and E85 (51-83%). Doing so will result in damaging the engine and the fuel system.
Other possible oxygenates include methanol. As a general rule of thumb, we advise you to avoid methanol since it’s a very corrosive substance. Genesis GV70 aren’t compatible with gasoline that has been mixed with methanol in any way or form.
Gasoline With Added Materials
Finally, we have to talk about additives in these types of gasoline. As a general rule of thumb, just using any additive marketed to you is a bad idea. This is because many aftermarket additives contain harmful elements to the fuel system and engine.
These elements are most likely going to be some form of silicon or micro metals. Even though many additives are supposed to clean your engine, many will harm your engine. Also, octane boosters are advised against since it’s better to immediately tank the proper octane levels.
To prevent you from figuring out what kind of additives are good or bad, it’s best to buy gasoline from certified TOP TIER gasoline retailers. Lexus for example, like many other carmakers, actually endorses buying this gasoline. This is because it already has all the proper additives mixed into it, and it has been proven to clean the engine and improve the lifespan of the engine.

What If I Hear A Knocking Noise From The Engine After Refilling?
Hearing a knocking noise in a car is a normal occurrence. However, it’s essential to listen carefully to the loudness of the knocking noise. A slight knocking noise is normal, especially when the car achieves peak performance (such as when towing or driving up a hill).
However, a loud knocking noise is a problem, especially if you refilled the car. In this case, you’re likely using gasoline with a lower than recommended octane level, and the car is not handling this well. In the case of the GV70, this means filling the car up with 87 – 89 octane.
In the instance in which you do hear a loud knocking noise, the best thing to do is stop the car and call your dealer or garage. It’s very likely the car needs to be drained from its fuel, and the fuel filter will need to be changed. Ignoring the knocking noise will result in severe mechanical damage.
Does the Genesis GV70 Have Good Gas Mileage?
Furthermore, it’s important to know more about the gas mileage a GV70 gets. As can be expected, this luxury SUV is not particularly developed for its phenomenal fuel economy. As can be seen in the table below, the 2.5 L engine gets a combined MPG of 24, whereas the larger 3.5 L engine is stuck at the 21-mark.
| Engine | Combined | City | Highway |
| 2.5 | 24 | 22 | 28 |
| 3.5 | 21 | 19 | 24 |
What’s The Gas Tank Size Of A Genesis GV70?
Genesis GV70 have a fuel tank capacity of 15.8 gallons or 60 liters. Assuming an average gallon price of $4 this means it costs $63,20 to fill up a GV70.
Closing Thoughts
The Genesis GV70 is a machine crafted for performance and luxury, and as such, it demands high-quality fuel. Specifically, it requires premium unleaded gasoline with an octane rating of 91. If 91 octane is not accessible, opting for a 93 or 95 octane is a prudent move.
Fuel is more than just a necessity; it’s the element that brings your GV70 to life, so it’s essential to get it right.
