Gas for the Hyundai Tucson must be at least 87 octane unleaded. Parts for cars will ultimately stop working. Every 30,000 miles, the gasoline filter needs to be replaced. You will experience performance issues if it doesn’t. To get the most miles per gallon, the fuel must burn extremely. Your gas tank must be in excellent condition. You will eventually run into problems. There could be a faulty control valve. The fuel tank can come undone. There can be gas leaks, which require immediate investigation. It can be quite a nuisance to cope with the stuck gas cap.
In Tucson, 87 min octane is needed. Based on a call to Hyundai’s corporate office in California. It does call for “Top Tier” fuel. Almost all of the premium names are rated in that category.
In my 22 Tucson hybrid, my mpg has been really low. According to the Hyundai service manager in Colorado Springs, this is normal during the break-in phase (defined as less than 4000 miles). Additionally, he cautioned against using 91 octane petrol. Use ordinary gas with an octane rating of 87 or even 85.

Hyundai Tucson SEL in 2022: I’m hoping someone can shed some light on this sentence from the car’s manual:
This is for the inline 4-cylinder, naturally aspirated base engine (Smartstream G 2.5 GDI). When I saw this, I was more than surprised. Both fueleconomy.gov and Hyundai dealers promote this trim as consuming normal gasoline. The phrase “premium gasoline is necessary” in the manual goes beyond the more usual phrase “premium gasoline is suggested.” I called the dealer, who informed me that ordinary gas should be used and that premium was merely advised, not required. But the “truth” should be contained in the vehicle manual. Can someone confirm that my decision to use premium for the time being is the right one? Do I need to use premium fuel? Although the engine may be tuned differently, the base Sonata only comes with a normal gasoline engine.
Fuel Types Used By A Hyundai Tucson (All Generations)
We’ve written a lot about the American-built Hyundai Tucson and its different characteristics on this blog. Today, we’ll discuss the type of fuel that this SUV need to function properly. Let’s begin by providing a succinct response to that query:
In the USA and other countries, ordinary unleaded gasoline has an octane rating of 87 AKI, whereas in other countries, it has a rating of 91 RON (Europe only). The Tucson of the year 2021 runs on premium unleaded fuel with an octane rating of 91 AKI (for usage in the USA and other countries) or 95 RON (Europe only). When the temperature is above 23°F (–5°C), Tucsons with diesel engines use No. 2 Ultra Low Sulfur (climatized) diesel, and when the temperature is below 23°F (–5°C), they use No. 1 Ultra Low Sulfur diesel (-5degC).
That doesn’t, however, completely address the subject. We’ll discuss the various types of fuel that are sold below and whether or not they work with the Hyundai Tucson. In addition, we’ll discuss the Tucson’s fuel economy, tank capacity, and fill-up prices. Read on!
Do I need octane for my 2022 Tucson?
The 2.5L 2497CC l4 GAS DOHC Naturally Aspirated engine in my 2022 Hyundai Tucson SEL is brand new.
Dealers for Hyundai promote this car as consuming normal gasoline. There isn’t a sticker or other reminder to use premium anywhere to be found. Only in the handbook, which I read after I bought it, is there a sentence that says premium gasoline 91 octane or higher is REQUIRED, which goes beyond the more common “premium gasoline is recommended” comment. When I called the dealer, they told me that standard 87 was already in the car and that premium was merely advised, not essential. However, as you advise, READ THE MANUAL and abide by it. To at least protect you from a warranty rejection!
When I contacted Hyundai, they advised me to visit a Hyundai Service Center because they were unable to provide any information beyond the manual. lol! I spoke with a service center clown who said you “should” be alright as long as the check engine light doesn’t come on or you notice any vibration or knocking. That’s the response I receive, ya. Obviously the service department. wants me to arrive with an engine problem! Lol
So, I ask: Do you honestly believe that running 87 will damage my engine? Although the manual specifies 91 and they might void my warranty if they find out I’m running 87, what else? Really?
Many thanks Scotty; I like watching you every day and value your expertise! A fun man like you!
I recently bought the same automobile and encountered the same issue. What has changed since you’ve owned it for almost a year? The octane you used was. Regular gas can be utilized on the government website. As a result, the data are inconsistent. View the link.
And based on what I’ve already observed, it’s not a good engine: it consumes oil even when brand-new; cat chunks break off and get sucked into the cylinders (a problem unique to Hyundai engines; the cat is too close to the engine, which I assume causes higher cat temperature for emissions); and it has hydraulic tappets, which is problematic given the longer maintenance intervals Hyundai recommends. Hyundai estimates it to have 150k miles, however I suppose that will depend.
Do you have any images of the instruction manual or the sources you used? As a NA 4 cylinder, I’m certain that it needs standard gasoline. Even though premium is advised, you can still get by with normal and your engine won’t suffer.
Follow the instructions in your owner’s manual. Since Hyundai engines (and dealer/warranty servicing) are already in doubt, I would abide by their specifications. Additionally, as you can see below, you should stick to higher octane gas if you switch to a lower octane and experience knocking.
The OP stated in his initial post that the owner’s manual for his vehicle calls for 91 octane. It goes beyond the standard “premium fuel is suggested,” he claimed.

Only regular unleaded petrol, or 87 octane as determined by the (R+M)/2 technique, is needed for the 2022 Hyundai Tucson. I think that’s how octane ratings are shown in all US gas stations. Note: Hyundai does strongly advise using fuel that complies with the TOP TIER program’s guidelines; a list of these fuels may be found here: top-tier brands of gasoline. — Hope this was useful.
How is the fuel tank on a 2022 Hyundai Tucson opened?
The term “88-octane” is simply another name for “e15 gas.” This fuel blend combines regular petrol with ethanol to the tune of 15%. No more than 10% ethanol is permitted in 87-octane fuel. There is an extra 5% ethanol in 88 as opposed to 87.
Are Hyundai Tucson vehicles dependable?

Can E85 be used in a 2022 Hyundai Tucson?
E15, which is frequently marketed as Unleaded 88 at the pump due to its octane rating, is safe to use in any automobiles, trucks, and SUVs manufactured after 2001. More than 90% of the cars on American roads now are from those model years. According to the ethanol business, the fuel has undergone some of the most extensive testing ever and has no impact on how a car drives.
Are Tucson automobiles reliable?
No, premium fuel does not keep running longer in a fuel tank than conventional fuel. If a car has been idle for a while, the owner might start thinking about how long a tank of gas will last.
Tucson’s all diesel, right?
Is a pre-owned Hyundai Tucson 4×4 trustworthy? In our most recent poll, the Tucson had a high reliability rating of 97.8%, placing it third out of 28 vehicles in the family SUV category. Additionally, the brand of Hyundai performed admirably, placing third out of 30 manufacturers.
Will 89 fuel damage my car?
Most of the time, the car will run just fine, although you might notice less power and reduced gas mileage. Because the fuel isn’t burning properly in more acute cases, you might hear engine banging or valve chatter. You should take it to your mechanic because these things could harm your engine.
What kind of vehicles need premium fuel?
The octane rating tells you how volatile a certain grade of gasoline is. The octane level rating for regular gas ranges from 85 to 88, with an average rating of 87. The octane rating for plus grade gas ranges from 88 to 90, with an average of 89. The average octane rating of premium gas, which ranges from 90 to plus, is around 92.
Describe ordinary gas.
According to octane rating, retail gas stations in the United States offer three different classes of gasoline: Regular (the lowest octane fuel-generally 87) (the lowest octane fuel-generally 87) Midgrade (the medium range octane fuel-generally 89-90) (the middle range octane fuel-generally 89-90) Premium (the highest octane fuel-generally 91-94) (the highest octane fuel-generally 91-94)
Burning of 89 gas is slower.
“Use 91 octane or higher premium unleaded fuel that has been posted on the label. If the octane level is below 91, you risk damaging the engine and voiding the warranty on your car. When using gasoline with an octane rating of 91 or above, the engine requires maintenance if loud banging is observed.”
Is premium fuel more durable?
If a luxury car has a high performance or turbocharged engine, premium gas may be necessary. More opulent trim levels for a car may offer engine choices that need premium petrol even if you’re not buying a luxury model.
What makes 87 and 89 gas different from one another?
I’ve read earlier postings where it was mentioned that the 2022 Tucson SEL is described as such in some (older) manuals: Only unleaded fuel with an octane number ((R+M)/2) of 91 (Research Octane Number 95) or higher is intended for use in your new car.
What makes 87 octane gas different from 88 octane gas?
Your car is incompatible with “E85.” The use of “E85” could harm your car’s engine and fuel system and result in poor engine performance. Customers are advised by Hyundai not to use fuel with an ethanol percentage higher than 15%.
Definition of “flex fuel”
- Cut the engine off.
- Lock the door to the driver.
- To open the fuel door, push the fuel door’s middle edge.
- The gasoline cap is visible when the door opens.
- Open the gasoline lid by turning it counterclockwise.
- refuel the car
What occurs if you enter 89 rather than 87?
Internal combustion engines are used in flexible fuel vehicles (FFVs), which may run on gasoline or any gasoline-ethanol mixture up to an ethanol content of 83%. E85 (or flex fuel) is a gasoline-ethanol mixture that, depending on the region and the time of year, contains 51% to 83% ethanol.
