Gasoline is an essential commodity in our daily lives, and we all know that it comes in various grades. Two of the most common grades available in gas stations are 87 and 88 octane. But what exactly is the difference between these two types of gasoline, and which one should you use for your vehicle? In this article, we will explore the differences between 88 and 87 gas and help you understand which one is better for your car.
What is Octane Rating?
Before we dive into the specifics of 88 and 87 gas, let's first discuss what octane rating is. Octane rating is a measure of a fuel's ability to resist "knocking." Knocking is a phenomenon where the air-fuel mixture in the engine's combustion chamber ignites unevenly, causing a knocking or pinging sound. Knocking can damage the engine and reduce its efficiency. The higher the octane rating, the more resistant the fuel is to knocking.
All gasoline sold in the United States has an octane rating printed on the pump, usually in the form of two numbers separated by a slash (e.g., 87/88). The first number is the minimum octane rating required by most cars, while the second number is the maximum octane rating that the fuel can have. Now that we know what octane rating is let's discuss the difference between 88 and 87 gas.
What is 88 Gas?
88 gas, also known as premium or high-octane gasoline, has an octane rating of 88 or higher. It is more expensive than regular gasoline because it contains more additives that increase its octane rating. Most high-performance cars require 88 gas because their engines are designed to burn fuel at higher temperatures and pressures, which can cause knocking if the fuel has a low octane rating.
If your car is designed to run on 88 gas, using a lower octane fuel can cause knocking, which can damage the engine over time. However, using 88 gas in a car that is designed to run on 87 gas will not provide any benefits and is a waste of money since the engine is not designed to take advantage of the higher octane rating.
What is 87 Gas?
87 gas, also known as regular gasoline, has an octane rating of 87. It is the most commonly used gasoline in the United States and is suitable for most cars on the road. Most car manufacturers design their engines to run on 87 gas, and using a higher octane fuel is unnecessary and a waste of money.
Using 87 gas in a car that requires 88 gas can cause knocking, which can damage the engine over time. However, using 87 gas in a car that is designed to run on 91 or 93 gas will not provide any benefits and can even reduce the engine's performance.
Which One Should You Use?
Now that we have discussed the differences between 88 and 87 gas, which one should you use for your car? The answer depends on your car's manufacturer's recommendations. Most cars on the road today are designed to run on 87 gas, and using a higher octane fuel will not provide any benefits. However, if your car requires 88 gas, using 87 gas can cause knocking and damage the engine over time.
Using the right gasoline for your car is essential to ensure optimal performance and prevent engine damage. Always check your car's owner manual or consult with a professional mechanic to determine the right fuel for your vehicle. Remember that using a higher octane fuel than what is recommended for your car is a waste of money and will not provide any benefits.
In conclusion, the difference between 88 and 87 gas is the octane rating. 88 gas has a higher octane rating than 87 gas and is suitable for high-performance cars that require it. 87 gas is the most commonly used gasoline in the United States and is suitable for most cars on the road. Always use the gasoline recommended by your car manufacturer to ensure optimal performance and prevent engine damage.
