Mid-grade fuel is usually 89 octane
Mid-grade fuel, also known as mid-grade gasoline, is a type of fuel that falls between regular and premium fuel in terms of quality and price. It typically has an octane rating of 89, although it can sometimes be rated at 88 or 90. It is often marketed as "Super" or "Super Premium", but these labels refer to its octane rating. The octane rating of a fuel is based on the pressure at which it will spontaneously combust in a testing engine, with higher octane numbers indicating greater fuel stability. Mid-grade fuel is recommended for certain vehicles, such as Fiat Chrysler's Hemi 5.7-liter V-8 engine, which recommends the use of 89-octane fuel.
When deciding which type of fuel to use, it is important to refer to the vehicle's owner's manual, which will specify the minimum octane level required for the vehicle. Using a higher octane fuel than is required for your vehicle will not provide any additional benefits and will only result in wasted money. For example, if your car's manual recommends regular fuel, which typically has an octane rating of 87, there is no advantage to using mid-grade or premium fuel.
However, if your car's manual recommends or requires the use of mid-grade fuel, it is important to use this type of fuel to ensure optimal performance and avoid any potential issues. Mid-grade fuel is designed for vehicles with specific engine requirements, and using a lower octane fuel in these vehicles may result in reduced performance or engine damage.
The price difference between regular and mid-grade fuel can be significant, with mid-grade fuel costing around 50 cents more per gallon on average. Therefore, it is essential to factor in the additional cost of mid-grade fuel when purchasing a vehicle that requires it. Additionally, it is worth noting that the difference in price between mid-grade and premium fuel is smaller, and the benefits of using premium fuel may outweigh the cost for some drivers.

It is a waste of money to use mid-grade fuel in a car that requires regular fuel
Most gas stations offer three grades of gasoline: regular, mid-grade, and premium. Regular gasoline typically has an octane rating of 87, while mid-grade falls in the 88-89 range, and premium is 91-94.
If your car's engine is designed to run on regular fuel, using mid-grade is a waste of money. Higher grades of gasoline do not contain more energy for your car to run on, and your car will not perform better because you put premium gas in the tank. The only time you should use premium fuel is if your car's manual recommends or requires it. If your owner's manual says to use 87 octane gasoline, you will save money by buying cheap gasoline. There is no advantage to running mid-grade or premium gas in your car.
For example, during a Car and Driver test, an Accord powered by a 3.0-liter V-6 made more power and accelerated quicker on regular fuel than on premium. Similarly, the Honda CR-V, which asks for 87 octane, showed no improvement in performance when tested with 93 octane fuel.
However, it is important to note that if your car requires premium fuel, using regular unleaded gas can reduce engine performance and cause damage over time. Additionally, if your engine is knocking when you use regular gas, your car might need a mechanic.

Premium fuel is required for optimal engine performance in luxury or high-performance models
Most gas stations offer three grades of gasoline: regular, mid-grade, and premium. While most cars are optimized to run on regular gas, luxury or high-performance models may require premium fuel for optimal engine performance.
Premium fuel is recommended or required for vehicles with high-performance engines, such as those with high compression ratios or turbochargers. These engines are designed to take advantage of the higher octane ratings of premium fuel, which can range from 90 to 94 octane. The higher octane rating helps to prevent engine knock or "pinging", which can occur when vaporized fuel and air mix and ignite at the wrong time in the combustion chamber. While this may not cause immediate damage, frequent engine knock can lead to a decline in engine performance over time.
Performance Benefits of Premium Fuel
For vehicles that require or are designed to run on premium fuel, using the recommended fuel grade can provide noticeable performance benefits. In turbocharged engines, for example, the use of premium fuel can result in improved acceleration and overall engine performance. This is because higher-octane fuels enable more ignition advance, allowing spark plugs to fire sooner and the engine to generate more power.
Cost Considerations
It is important to note that premium fuel typically costs more than regular gasoline, often by 50 cents or more per gallon. Therefore, it is generally not recommended to use premium fuel in vehicles that are designed to run on regular gasoline, as it will not provide any additional benefits and may only result in higher fuel costs. However, if you own a luxury or high-performance vehicle, using the recommended premium fuel can help ensure optimal engine performance and maintain the health of your engine over time.
Consulting Vehicle Manuals
To determine the appropriate fuel grade for your vehicle, it is essential to refer to the owner's manual. The manual will specify the recommended octane rating for your vehicle's engine, ensuring optimal performance and fuel efficiency. In some cases, the fuel requirements may also be indicated on a label near the gas cap or by the fuel gauge.
