What type of fuel can a Hyundai Elantra run on?
The Hyundai Elantra requires normal unleaded gasoline with an octane rating of 87 or higher for all models and model years. Technically speaking, “higher” will work, but research shows there is no benefit to using premium fuel in an engine whose compression ratio does not require it, as the Elantra’s does. Having said that, Hyundai does not currently have any vehicles that can run on flex fuel, so you shouldn’t use anything like E85 either. Regular unleaded 87 is the only fuel you should use for the best price and performance; anything less can damage your engine and cause knocking, and anything more will cost you more money in the long run.
details on the Hyundai Elantra’s fuel. Your new car is made to only run on unleaded fuel that has a pump octane ((r+m)/2) number of 87 or higher (research octane number 91). Unleaded petrol is used in your new car to increase efficiency, lower exhaust emissions, and prevent spark plug fouling.

Ethanol or Methanol in Gasoline
It’s important to remember what fuels may and cannot be used while refueling the Hyundai Elantra. Ethanol is one of the fuel components that requires caution. Regular gasoline contains ethanol, which poses no hazard to your engine in modest amounts. However, bear in mind the following:
Hyundai Elantras produced from 2000 to 2016 can only use fuel containing a maximum of 10% ethanol (E-10). Hyundai Elantras produced after 2016 can only utilize fuel with a maximum 15% ethanol content (E-15). The E-85 fuel, which is a blend of 15% conventional gasoline and 85% ethanol, cannot be used with any generation of the Elantra. Excessive engine damage that is not covered by any warranty will result from exceeding these standards.
It’s also important to remember that no Elantra can run on methanol and that doing so would result in warranty-voiding engine damage.
What type of fuel will a Hyundai Elantra run on?
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.

Will 89 fuel damage my car?
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.
Should you fill a new car with premium gas?
High-tech fuel monitoring features and electronics in modern cars are easily adaptable to various gasoline grades. There is no risk of imminent engine damage if you need to fill up with a tank of lower octane fuel, even though the manufacturer recommends premium gas for your automobile.
What type of gas should I use?
The cheapest fuel that your car’s engine can run on is the solution. If your car was built to run on ordinary octane gas, premium gas won’t increase the performance or power of your engine. Please consult your owner’s manual to establish the octane rating your car requires. Once more, if it says “premium fuel required,” go with premium. You can choose between ordinary or premium fuel if the owner’s handbook says “premium fuel suggested.” For these kinds of engines, the higher octane rating may result in a minor increase in power or fuel efficiency.
Can 87 and 91 gas be combined?
Yes, drivers are allowed to mix the two fuel kinds. According to The Drive, the mixture of gas types will produce an octane level somewhere in the center, which the vehicle “will survive.”
What is deemed premium gasoline?
Because it has an octane rating between 91 and 94, premium gas is also frequently referred to as high-octane gas. A midgrade gas has an octane rating between 88 and 90, while regular gas normally has an octane value of 87. Although some engines operate better with premium gas, it is a fallacy that premium gas is more fuel efficient. Any increase in fuel economy would result from engine performance rather than gas itself. Purchasing premium fuel won’t reduce how frequently you visit gas stations, particularly if you have a conventional engine that isn’t built to take advantage of premium fuel.
When is premium gas recommended?
According to AAA’s manager of technical services, Michael Calkins, choosing premium gas is easy. Two words sum up when to utilize premium: necessary or advised.
You must use premium gas if it is specified as such in your car’s owner’s handbook (or on the inside of the gas door) in order to protect your engine.
When premium fuel is suggested in your owner’s handbook or on the inside of the gas door, you can still use your vehicle with lesser grade fuel.
According to a November 2017 AAA study, premium petrol may very marginally enhance performance (increased horsepower) and fuel efficiency for vehicles that merely recommend it. But until you take out a stopwatch and run the quarter mile, you probably won’t notice a difference in performance.
The bottom line: Don’t bother if your automobile doesn’t need premium. According to Calkins, when you purchase lower grade fuel, “the savings you obtain are significantly more than the expense of the loss in fuel economy.”
If you don’t use premium gas, what happens?
For an automobile whose engine requires premium fuel, the situation is different. In an emergency, the automobile will run on standard fuel, but you shouldn’t do it frequently. The lower octane of the fuel can lead to higher exhaust-gas temperatures and potential knocking, both of which can eventually be harmful to the engine’s health.
