What You'll Learn
Premium vs. regular gas
The octane rating of fuel is a measure of the fuel's tendency to ignite (or knock) from the compression force of the piston. Regular grade gas is typically rated at 89 octane, while premium is rated at 91 octane. Higher octane fuel can be compressed to a higher ratio without detonating erratically, which usually manifests as knocking or pinging.
Some cars require premium gas, while others simply carry a recommendation that owners use it. If a vehicle is meant to use regular gasoline, there are no benefits to purchasing premium gasoline. However, if a car requires premium to run, it means the compression has been tuned to not knock on premium fuel. If regular fuel is used, it will knock, and the computer will adjust the spark timing to compensate, resulting in less power.
Performance cars with higher-end engines may require the more advanced formula of premium gasoline to maximize their horsepower and torque. However, if you drive an everyday sedan or SUV, premium gasoline might be unnecessary. There may be no difference in performance between premium and regular gasoline, as these cars were built to run effectively on unleaded. If the manufacturer recommends regular gas, you might as well save money at the pump!
According to the AAA's national average gas prices, the difference between regular and premium gas is $0.80. Owners who pay for premium when they don't need it can find a real dent in their budget. In a vehicle averaging 25 mpg and traveling 15,000 miles a year, that amounts to a $354 annual surcharge for using premium fuel.
It's important to note that whether a car takes regular grade gas or prefers premium, it's a good idea to only use "top-tier" fuel. It contains extra additives that help prevent performance-crippling deposits in sophisticated fuel delivery systems.

Cost implications
The cost implications of using premium fuel are significant, especially considering the price difference between regular and premium fuel. As of July 2024, the difference between regular and premium gas was 80 cents, according to AAA's national average gas prices. This can result in owners paying hundreds of dollars more per year if their vehicle requires premium fuel. For example, a vehicle rated at 25 mpg that takes premium-grade gas will cost an average of $300 more to drive per year than one that takes regular gas. Over a five-year period, this can amount to an extra $1,500 in fuel costs.
Additionally, choosing a car that runs on regular gas has become increasingly difficult as more vehicles, including those from mainstream brands, now require premium fuel. More than half of all new vehicles sold in 2024 require higher-octane gas, which can be a surprise to some new-vehicle buyers. This means that buyers have a more limited selection of vehicles if they specifically want a car that runs on regular gas, which can impact their budget and vehicle choices.
While some luxury and performance models still run on regular-grade gas, there is a common misconception that luxury vehicles require premium fuel. This misconception leads many luxury vehicle owners to buy premium gas unnecessarily, incurring higher fuel costs. However, several luxury vehicles, such as the 2014 Volvo XC90, 2013 Infiniti M37, 2015 Lexus ES350, 2012 Cadillac CTS, 2011 Lexus CT200h, and 2010 Lincoln MKS, perform perfectly fine with regular gas.
It is worth noting that using regular gas in a vehicle designed for premium fuel may have potential drawbacks. Running a vehicle designed for high-octane fuel on lower octane can lead to engine knocking and a decrease in power and efficiency. While modern cars may have knock sensors to prevent this, it can still impact the long-term health of the engine and potentially lead to costly repairs. Therefore, it is essential to consider the vehicle's preferences and performance when selecting fuel to avoid any negative consequences.

Performance and speed
The octane rating of fuel is a measure of how much compression it can withstand before igniting. Regular grade gas typically has an octane rating of 87 or 89, while premium fuel has a rating of 91 or above. Higher octane fuel can be compressed to a higher ratio without detonating erratically, which can manifest as "knocking" or "pinging". Knocking refers to the rattling noise produced when the fuel-air mixture in the engine detonates in more than one place at a time.
Higher octane fuel allows the engine controller to dial in more aggressive timing and higher boost pressures, improving performance and speed. This is especially true for turbocharged engines, which are more likely to require high-octane fuel. Turbochargers allow automakers to get more performance out of a smaller engine.
However, it is important to note that using premium fuel does not always translate to better performance and speed. If a car is built to consume 89-octane regular gas, using premium fuel will not provide any additional benefits. In fact, a study by the AAA found that using premium fuel in vehicles designed to run on regular fuel could result in wasted money.
When it comes to new cars, the requirement for premium fuel varies depending on the make and model. While luxury and sports cars often require high-octane fuel, there are also mainstream brands that now specify the use of premium fuel. For example, in 2023, all gas-powered MINI Coopers recommended premium fuel. On the other hand, not all powertrains in the 2023 Chevrolet Camaro and Corvette sports car lines required premium. It is always recommended to refer to the owner's manual to determine the appropriate fuel type for a specific vehicle.

Luxury cars
There is a common misconception that luxury vehicles must be filled with premium gas. While some luxury cars do require premium gas, many do not. The key factor in determining whether a car requires premium gas is the engine compression ratio. High-performance engines, which are common in luxury cars, typically have higher compression ratios. These engines compress the air-fuel mixture to a greater degree prior to ignition, which can lead to increased pressure within the combustion chamber.
The use of premium gas can ensure maximum performance and fuel efficiency in luxury cars, but it is not always necessary. Premium gas has a higher octane rating, which means it is more resistant to "knocking" or "pinging" during combustion. Knocking occurs when the fuel-air mixture ignites unevenly or prematurely after the spark plug fires, causing abnormal combustion and pressure waves that collide, creating a knocking sound. Repeated knocking can eventually cause permanent damage to the engine.
While modern engines have some adaptability, using regular gas in a luxury car designed for premium fuel can lead to reduced performance, lower fuel efficiency, increased engine wear, and potential warranty issues. However, some luxury car owners alternate between premium and mid-grade fuel for daily driving, reserving premium for high-performance situations. Ultimately, it is important to refer to the owner's manual for the recommended fuel type, as using the correct fuel is critical to prolonging the vehicle's lifespan and optimizing its performance.
