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!

What type of fuel is best for a Hyundai Tucson?
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.

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.
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 couldn’t provide any information beyond what was in the manual. 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. Naturally, the service department wants me to visit them 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.
What kind of fuel does Hyundai advise?
Standard and Plus The majority of automobiles can run on 87 octane gasoline, also known as “normal” or “regular unleaded” gasoline.
Can E85 be used in a 2022 Hyundai Tucson?
- Leaded or unleaded gasoline is sold alongside or in place of gasohol, a blend of gasoline and ethanol (commonly known as grain alcohol). For instance, “E15” gasoline contains 85% gasoline and 15% ethanol.
- Avoid using gasoline or gasohol that contains more than 15% ethanol or any methanol at all. Both of these fuels have the potential to harm the engine control system, emission control system, and fuel system in addition to causing drivability issues.
- Any type of gasohol should not be used anymore if driving becomes difficult.
- The alternative fuel known as “E85” is produced specifically for use in flexible fuel vehicles and contains 85% ethanol and 15% gasoline. 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 that contains more than 15% ethanol.
- Never use methanol-containing gasohol.
- Never use gasoline that has 15% or more ethanol.
- Never use leaded gasoline or fuel.
- Use only “E85” fuel.
Your New Vehicle Limited Warranty does not cover performance issues or harm to the fuel system brought on by the use of “E85” fuel.
Do Hyundai vehicles demand premium fuel?
It does seem like premium gas would be preferable to regular. However, many vehicles—including yours—do not operate in this manner.
A Hyundai Elantra uses standard unleaded fuel with an octane rating of 87. It is better to utilize the suggested ordinary unleaded petrol as premium gas does nothing unique for your engine.
Remember that premium petrol is also more expensive! You all want to save money wherever you can, especially with the already-exorbitant rates of gas. and Jerry can help you begin your auto insurance comparison shopping.

What kind of vehicles need premium fuel?
If a luxury car has a high performance or turbocharged engine, premium gas may be necessary. More opulent trim levels for a car may provide engine options that require premium gas, even if you’re not buying a luxury vehicle. The make and type of your car ultimately determines whether it requires premium gas or not. Find out more about luxury and sports car insurance.

What happens if 89 gasoline is placed in a 91 vehicle?
When a vehicle manufacturer specifies premium fuel, it’s because the fuel system of that specific vehicle is built to function best with higher octane fuel. In an engine that needs premium fuel, using normal petrol could violate your warranty. That is most likely to occur if repeated use results in severe engine knocking or pinging (premature fuel ignition, also known as detonation), which harms the pistons or other engine components. Other issues, such as worsened engine performance and poorer fuel economy, may result from using the incorrect gasoline.
As an illustration, the following is what GM states about the matter in the owner’s guide for a car that needs premium:
“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.”
Keep in mind that this only applies to engines that demand premium gas. Although some manufacturers advise using premium gas, you can also use standard or mid-grade gas. Usually, they mention that using gas with a lower octane rating could affect performance and fuel efficiency. They advise using premium when that starts to become noticeable, or if engine knock starts to happen.
Does my Hyundai work with E10?
1. Can I fuel my Hyundai with E10? All Hyundai cars developed since 2005, as well as a few of our previous models produced since the late 1990s, may use E10. Today, almost all gasoline-powered vehicles on the road can also use E5.
