What kind of fuel does a Kia run on?
You normally have three alternatives when you fill up at your neighborhood gas station.
87, 89, and 93 octane gasoline. The majority of Kia owners can fill up with regular 87-octane fuel. The 2021 Kia Stinger with track tuning is the only Kia car that suggests using Premium 93-Octane fuel. The Kia Stinger’s two turbocharged engine options will enhance performance with Premium 93-Octane fuel at every turn.
What Are the Differences Between Regular and Premium Fuel?
Regular and premium fuel differ in crucial ways, which many drivers may not be aware of if they want to maximize performance and fuel efficiency. The octane number, which measures how resistant the fuel is to knocking or igniting too soon in your engine, determines the fuel grade. The higher the octane rating, the cleaner the performance. Most states classify 91- and 93-octane as premium grades, with 87-octane being the ordinary grade and using additional additives. The majority of automobiles will operate efficiently using regular octane fuel. For automobiles with turbocharged engines, premium octane fuel is often advised or necessary as it will burn cleaner and more effectively to boost performance.
The best gas for a Kia?
Fuel Needs for Kia Automobiles These days, ordinary 87-octane fuel is the norm and what automobiles are built to run on, even new Kia models.
87 normal gas is it?
Any type of gasoline with an octane level of 91 or higher is commonly referred to as premium gasoline, with 91 octane and 93 octane being the most popular brands sold at gas stations in the United States (93 octane gasoline may be called “ultra or “super-premium in some cases). Most gas stations designate gasoline with an octane level of 89 as “midgrade,” whereas gasoline with an octane level of 87 is known as “regular.”
What kind of fuel is 87 octane?
Measures of gasoline stability are called octane ratings. These rankings are based on the pressure at which a gasoline will spontaneously ignite in an engine under test. Actually, the octane number is the simple average of two separate octane rating techniques, research octane rating (RON) and motor octane rating (MOR), which differ mainly in the particulars of the operating conditions. The fuel is more stable the higher the octane number. According to octane rating, retail gas stations in the United States offer three different classes of gasoline:
- Regular (the lowest octane fuelgenerally 87) (the lowest octane fuelgenerally 87)
- Midgrade (the middle range octane fuelgenerally 8990)
- Premium (the highest octane fuelgenerally 9194)
The octane rating is referenced in all of the names for these kinds of gasoline that certain corporations use, including unleaded, super, and super premium.

The minimum octane rating is shown by the huge number on the yellow octane label on petrol pumps. The octane testing method is identified on the label as (R+M)/2 Method, where R stands for Research Octane Number and M for Motor Octane Number.
The 2,2,4-Trimethylpentane molecule, which is extremely resistant to auto-ignition, is one of the 18 isomers of regular octane (C8H18), which is where the name of the fuel comes from. For testing purposes, this iso-octane has been given the reference value of 100. The 0 octane reference fuel is the exceedingly unstable normal heptane (C7H16) molecule.
Which automobiles can use 88 gas?
- E15, which is frequently marketed as Unleaded 88, is a mixture of 15% ethanol and 85% gasoline. It has 5% more ethanol in it than E10, the most widely used fuel in the US. While E10 has an octane rating of 87, E15 has a higher octane typical of 88. To emphasize its high octane value, retailers are selling E15 as Unleaded 88.
- Up until recently, gasoline ethanol mixes could include no more than 10% ethanol, or E10. 97 percent of the gasoline sold in the US is E10. Unleaded 88 uses the same kind of ethanol as is blended into E10, but the amount of ethanol in a gallon of gasoline is increased from 10% to 15%.
- The U.S. Environmental Protection Agency (EPA) has given unleaded 88 permission to be used in all automobiles, trucks, and SUVs manufactured in 2001 and later. According to the EPA, more than 90% of gasoline sales is used in vehicles with a model year after 2001.
- The ethanol sector petitioned the EPA in 2009 to lift the current cap of 10% and allow a blend of up to 15% ethanol in gasoline. By replacing conventional gasoline with low-carbon ethanol, increasing the blend from E10 to E15 will hasten the use of renewable fuel, boost energy security, generate jobs in the United States, lower transportation costs, and benefit the environment.
- In the history of the EPA fuel waiver procedure, Unleaded 88 has undergone more testing than any other gasoline additive. The U.S. Department of Energy tested Unleaded 88 in a variety of vehicles for 6 million miles and found no issues.
- Unleaded 88 is permitted for use by automakers. More than 93 percent of model year 2019 vehicles have express manufacturer approval for the use of Unleaded 88, according to an RFA analysis. Ford recommends Unleaded 88 for its 2013 and newer vehicles, and General Motors recommends Unleaded 88 starting with its 2012 model year vehicles. Volkswagen, Audi, Toyota, Land Rover, Porsche, Jaguar, Honda, Subaru, and some Mercedes-Benz and Lexus cars are also permitted to run on unleaded 88.
- It’s also crucial to remember that certain fuels and gasoline additives, like fuel stabilizers or octane boosters, aren’t always included in vehicle owner’s manuals. The use of fuels and gasoline additives not specifically listed does not always make a vehicle’s warranty void. In fact, if the use of a different fuel did not cause the issue for which the warranty claim was submitted, vehicle manufacturers may not reject a warranty claim based on that reason.
- Unleaded 88 and normal gasoline have very imperceptible mileage differences in a real-world setting. In a controlled environment, ethanol’s effect on fuel economy would be equal to the loss of energy density, according to studies by Oak Ridge National Laboratory and the National Renewable Energy Laboratory. When compared to ordinary gasoline, this results in an Unleaded 88 loss of less than 2%. This would translate to a loss of about 29.4 mpg for a car getting 30 mpg, or roughly the loss of miles per gallon when a car’s tires are not properly inflated.
- Ethanol continues to dramatically cut greenhouse gas emissions, according to a U.S. Department of Agriculture report (GHG). According to the report, using ethanol as a transportation fuel reduces greenhouse gas emissions by 43%, and if current trends continue, these reductions will reach 47% by 2022.
- At the pump, unleaded 88 is clearly distinguished. For usage in passenger cars manufactured after 2001 and flex-fuel vehicles, look for the government-mandated orange and black label mentioning E15 (as seen on the right).
- Nearly all of the gasoline infrastructure that is currently in place can use unleaded 88 without risk of damage. According to studies by Underwriters Laboratories, gasoline blends having 15% ethanol should be used at American gas pumps.
- Unleaded 88 was not permitted to be used in automobiles manufactured before 2000 by the EPA. This was partly because older vehicles have a variety of factorssuch as mileage, state of repair, and types of usethat would render test results ambiguous.
- Because many non-automotive engines lack sophisticated computer controls to account for fuel variances, the EPA did not approve usage for Unleaded 88 outside of the automotive industry. These engines come in several sorts and sizes and are used in different applications.
Is premium fuel actually worthwhile?
Most vehicles accept standard, but few only accept premium. There have been some erroneous purchases made at the pump because it is not quite clear how these two kinds of gasoline differ from one another. Continue reading if you’re unsure about what to put in your car’s gas tank. You could end up saving money.
So, what’s the difference between premium and regular gas?
In most areas, regular gas has an octane rating of 87, whereas premium gas frequently has a higher rating of 91 or 93. Higher octane fuel can withstand greater compression before detonating. In essence, the risk that a detonation occurs at the wrong time decreases with increasing octane grade. This event will occasionally probably not cause any damage to your car. However, if it occurs frequently, it could hasten the performance deterioration of your engine.
For optimum performance and fuel economy, engines with high compression ratios or turbochargers frequently need the high octane gasoline found in premium gas. The majority of vehicles on the road today, however, are designed to run on ordinary gas.
If your car doesn’t require premium, fill up with regular.
Why spend a lot of money on something you don’t require? Premium petrol costs around 50 cents more per gallon than regular gas and doesn’t affect vehicles that can’t use it in any way. The Federal Trade Commission warns consumers that, “In most circumstances, using gasoline with a higher octane rating than your owner’s manual suggests delivers absolutely no benefit. It won’t improve the efficiency, performance, speed, or mileage of your vehicle.
In order to clean your engine and improve performance, the detergent additives in your gasoline are significantly more significant than the octane rating. Every shop offers a unique mixture of additives that are applied to all grades. For instance, Chevron’s Techron is available in both their normal and premium gas.
Some people hold themselves to a higher standard when it comes to additives. The Top Tier Gasoline standard, which requires a higher-percentage of detergent additive than the EPA minimum criteria, was developed with the assistance of BMW, General Motors, Honda, Toyota, Volkswagen, and Audi. They contend that lesser detergent additive concentrations may cause greater deposits to form on engine parts like the intake valves and fuel injectors. As a result, emissions may rise and engine performance may be affected. j
If your car requires premium, fill up with premium.
For high compression ratio engines to operate at their intended levels of performance, fuel economy, and emissions, higher octane gasoline is often required. Don’t cut corners if your car requires premium fuel. Your automobile will be less powerful and fuel-efficient even though you might save money on gas. When driving a car with a turbocharged engine, this can significantly alter the performance.
What if premium gas is needed but isn’t readily available? While newer automobiles have sensors that are watched by the engine’s computer to assist prevent knock and, by extension, engine damage, older ones may be subject to engine knock when driving on low octane fuel. As the engine’s computer can alter the ignition timing, your car will probably be alright running on normal occasionally, but we don’t advise doing so frequently.
A modern vehicle’s ECU (Electronic Control Unit) can take differing octane levels into account and adjust when you use a lower grade of fuel than what is advised or required. Your horsepower and MPG are likely to decrease as CO2 emissions increase. Gas may be cheaper, but in this case, you get what you pay for.
If your car only recommends premium, the choice is yours.
The Ford F-150 and Mazda MX-5 Miata are two examples of automobiles for which automakers advise premium fuels but do not mandate it. According to AAA’s research, these vehicles’ performance and fuel efficiency somewhat improved while using premium gas. If you drive a luxury or performance car, premium gas might assist highlight your car’s desired qualities.
However, you can safely run on ordinary if your owner’s handbook specifies “premium fuel suggested.” Commuters trying to get from point A to point b might not notice or care depending on what and how you drive. It all comes down to personal preference in the end. Your rules, your car.

It can be challenging to compare all the vehicles that are now on the market with rising gas prices. Check out these vehicles that use little to no gasoline to make things simpler! Check out these gas-saving suggestions as well.
Premium Gas Offers Better Performance
This myth is partially true and partially false. The majority of automobiles operate at the same level of performance whether you use standard or premium petrol. You’ll only notice a noticeable difference between the two with particular car models and engine types.
You Need to Use Premium Gas if It’s in Your Car Manual
This myth also rests on circumstantial evidence. Many automakers, like GMC, Ram trucks, and the works, will indicate in the owner’s manual for some of their cars whether they advise or demand the use of premium gasoline. What counts is how these two terms differ from one another.
There are certain advantages to using premium gas when the manual advises against it, but using regular gas won’t hurt your car. It won’t void your warranty in this situation either. Premium gas could potentially improve the performance of these vehicles.
But if the owner’s handbook specifies premium fuel, it signifies the engine does really require higher octane levels to operate properly. Using conventional fuel in these vehicles could potentially harm the engine, and your warranty won’t cover these damages.
Make sure you carefully study your owner’s manual before buying a new or used automobile to make the best decision. Save yourself the money if it’s not necessary.
Premium Gas Lasts Longer
So, is premium fuel more durable? This appears to be a lure of using the ostensibly higher grade fuel for many people. Who among us wouldn’t like to visit the petrol station less frequently?
Regrettably, premium gasoline contains nothing that would extend its shelf life relative to other fuels purchased at the pump. Since the higher octane levels are what set them apart, the only true advantage is a decreased risk of engine knocking, which poses no danger with most contemporary fuel systems.
Premium Gas Cleans Your Engine
This myth is untrue, much like the idea of living longer. The majority of engines are effective in removing residue. You’re in better shape keeping up with routine maintenance checks if you’re worried about the cleanliness of your vehicle’s components.
Can I fill up my automobile with premium gas?
Can I use unleaded fuel in a premium gas vehicle? Fuel Express claims that even if the manufacturer recommends premium gas for your car or truck, you may still use normal gas in it. However, if they need premium, pumping unleaded can be problematic.
