The gas mileage of a vehicle is determined by several factors such as engine efficiency, aerodynamics, vehicle weight, and driving habits. The difference between using 87 or 89 octane gasoline may not be significant since it’s only a 2-point difference in octane rating.
In general, higher performance engines require higher octane gas to prevent knocking or pre-ignition. However, if your vehicle manual recommends regular gas, using a higher grade will not provide any benefit in terms of fuel economy or engine performance.
According to the US Department of Energy, the average fuel economy of a passenger car in the US is around 24.9 mpg. With that said, using a higher octane gas doesn’t necessarily translate to better gas mileage if your driving habits are not efficient. Driving habits such as rapid acceleration, speeding, and idling can significantly decrease fuel efficiency.
To determine which type of gas will give you better gas mileage, it’s best to conduct a fuel consumption test. Fill your tank with 87 octane gas, record the mileage, and calculate how far you drove per gallon of gasoline. Then, repeat the same process using 89 octane gas. By comparing the results, you can determine which type of gas gives you better gas mileage.
The difference in fuel economy between using 87 or 89 octane gas varies depending on several factors. It’s best to follow the manufacturer’s recommended fuel type and maintain your car’s engine to maximize its efficiency. Additionally, adopting fuel-saving driving habits can help you save money on gas and reduce your carbon footprint.

Is it better to use 89 gas instead of 87?
Selecting the appropriate grade of gasoline for your vehicle is essential to maintain its optimum performance, fuel economy, and engine life. The grade of gasoline refers to its octane rating, which is a measure of how effectively the fuel would resist engine knock or pinging.
Typically, regular unleaded gasoline has an octane rating of 87, while mid-grade gasoline ranges from 89 to 90 octanes, and premium gasoline can range from 91 to 94 octanes. The general rule of thumb is that you should use the fuel grade recommended by your vehicle’s manufacturer. In most cases, such as non-performance vehicles, the manufacturer may indicate that regular unleaded gasoline is acceptable.
However, in some cases, you may find a manufacturer whose vehicles require a higher fuel grade for optimum performance. Higher octane gasoline is more resistant to engine knock because it burns more slowly and smoothly than lower octane gasoline. Hence, if your vehicle’s engine is designed to run on higher octane gasoline, it will produce more power and have better acceleration with the appropriate gasoline.
Moreover, premium gasoline may also contain more detergents and additives to minimize the buildup of deposits and maintain the fuel injectors’ cleanliness, which can enhance fuel economy and engine longevity. It can also help reduce emissions and protect the catalytic converter, which can lead to significant cost savings in the long run.
However, using a higher octane fuel than recommended by the manufacturer is not only unnecessary but also can be wasteful and expensive. If the engine requires regular unleaded gasoline, there may be no advantage to using a more expensive mid-grade or premium gasoline. Additionally, using higher octane gasoline in a lower octane requirement engine will not necessarily enhance the engine’s efficiency or power but will only cost more.
Hence, it is essential to refer to your vehicle’s owner’s manual or consult a licensed mechanic for advice regarding your vehicle’s fuel grade. That way, you can determine whether you require a particular grade of gasoline and avoid potential engine performance or fuel-related issues. using the recommended fuel grade ensures that your car runs optimally, efficiently, and cost-effectively without any harmful effects or damage to the engine.
Is there a big difference between 87 and 89 octane?
Yes, there is a significant difference between 87 and 89 octane fuel.
Octane rating indicates the fuel’s ability to resist knocking or detonation of the air-fuel mixture in the engine. The higher the octane rating, the better resistance it has against detonation. When the fuel detonates too early, it causes a knocking noise in the engine, causing damage to the engine’s components.
Therefore, it is essential to choose the right octane rating fuel for your vehicle.
The main difference between 87 and 89 octane fuel is their octane rating. 87 octane fuel is the regular unleaded gasoline available at most gas stations in the US. It is suitable for most cars on the road and has a lower price point than higher-octane fuels. On the other hand, 89 octane fuel contains additives that increase its octane rating.
This fuel type burns cleaner and more efficiently, providing better performance and fuel economy.
If your vehicle recommends 87 octane fuel, it is unnecessary to use higher-octane gasoline. However, if you use a higher-octane fuel when your vehicle’s engine is designed for 87 octane, it can lead to poor fuel economy and no extra performance gains. In contrast, if your vehicle requires 89 octane fuel, using a lower-octane gasoline can cause engine problems such as engine knocking and reduced power.
Therefore, choosing the right octane gas for your vehicle is essential for optimal engine performance and fuel efficiency. It is recommended to check your vehicle’s manual for the recommended octane rating and use fuel that meets the manufacturer’s requirements. While the cost of higher-octane fuel might be marginally higher, it provides better fuel economy and engine performance, helping you save in the long run.
Does 89 gas burn slower than 87?
The octane rating of gasoline determines how well the fuel resists knocking or pinging in your car’s engine. In simple terms, it indicates the fuel’s quality and ability to withstand compression before igniting.
The higher the octane rating, the less likely the fuel is to ignite under high-pressure conditions. Therefore, it seems reasonable to assume that 89 octane gas would burn slower than 87 octane gas.
However, the reality is somewhat more complicated. Gasoline’s combustion rate is influenced by multiple factors, including fuel quality, ignition timing, engine design, and driving conditions.
It’s true that higher octane fuel can help reduce engine “knock,” or detonation, but it doesn’t necessarily mean the fuel will burn slower than lower octane gas. In fact, the combustion rate might be faster with higher octane fuel because it can better resist detonation.
Additionally, the type of fuel you use can add some performance to your engine. Typically, higher octane fuels are recommended for high-performance engines or to compensate for high ambient temperatures.
While it’s hard to make a definitive statement about whether 89 gas burns slower than 87, it’s safe to say that it can perform better in high-performance engines and may be necessary in extremely hot weather conditions. However, in everyday driving with an average engine, there may be no discernible difference in actual burn speed.
Is 89 gas better for your car?
It depends on what type of car you have and what the manufacturer recommends for fuel. Generally, higher octane fuel, such as 89, is recommended for cars with high-performance engines that require a higher compression ratio for optimal performance. However, using a higher octane fuel than your car requires will not give you any additional benefits.
Using a lower octane fuel may cause knocking or pinging noises in the engine, which can lead to damage over time. This is because low octane fuel burns too quickly and may ignite before the spark plug ignites, causing the engine to misfire. It can also decrease fuel economy and cause the engine to run less efficiently.
Most modern cars are engineered to operate on regular unleaded gasoline with an octane rating of 87. However, some vehicles with turbocharged or supercharged engines may require premium gasoline with an octane rating of 91 or higher. It is important to check your owner’s manual or consult with a dealer or mechanic to see what type of fuel is recommended for your specific make and model.
Using 89 gas is only beneficial if it’s prescribed by the manufacturer, in other cases, the type of gasoline you should use depends on the specifications of your car’s engine. As a car owner, it is crucial to maintain the performance and durability of your vehicle by regularly following the recommended fuel guidelines and maintenance schedule.
What is the point of 89 gas?
89 gas, also known as mid-grade gasoline, is a type of fuel that falls in between regular and premium gasoline in terms of octane number. Octane number is a measure of a fuel’s ability to resist knocking or pinging during combustion, which could damage the engine.
The point of 89 gas is to provide a balance between cost and performance. Regular gasoline with lower octane numbers may be cheaper, but it may not be sufficient for high-performance engines that require a higher octane rating. On the other hand, premium gasoline with higher octane numbers may be too expensive for daily use in regular vehicles that do not require a higher octane rating.
That’s where 89 gas comes in. It offers a middle ground for drivers who want better performance than regular gasoline but at a lower cost than premium gasoline. It is recommended for use in vehicles with engines that require a mid-grade gasoline rating, usually in the range of 87-91 octane.
The point of 89 gas is to provide a cost-effective and optimal solution for those who want better than regular gasoline performance for vehicles that do not require premium gasoline.
Does 89 octane gas last longer?
The octane rating of gasoline refers to its ability to resist knock or detonation. This is the undesirable explosion or ‘pinging’ sound that occurs when the air/fuel mixture in the engine’s combustion chamber is ignited prematurely or sporadically. A higher octane rating means that a fuel can withstand a higher compression without detonating.
However, it does not necessarily mean that it will last longer.
The longevity of gasoline is influenced by a variety of factors, including storage conditions, composition, additives, and usage. High-quality gasoline, which typically has a higher octane rating, may last longer than low-quality gasoline, but this difference is minimal. More important is the freshness of the gasoline – that is, how recently it was produced.
Gasoline inevitably degrades over time due to exposure to oxygen and moisture. As a result, it can form clumps, debris, and varnish inside the fuel system, which can impair performance or cause damage to the engine over time. This deterioration process is accelerated with high temperatures, sunlight, or exposure to air, so it’s essential to store gasoline in a cool, dark, and dry place.
Another factor that affects gasoline’s lifespan is the type of additives used to enhance its properties. Some fuel companies may include detergents, rust inhibitors, or corrosion inhibitors to maintain the fuel, reduce deposits, or prevent rust from forming in the fuel system. These additives can extend gasoline’s shelf life and also provide benefits for engine efficiency and emissions control.
The octane rating of gasoline does not necessarily correlate with its longevity. The lifespan of gasoline is determined by various factors, including storage conditions, composition, additives, and usage. Still, generally, high-quality gasoline with better additives, and low ethanol content will last longer.
Therefore, it is essential to use gasoline within a reasonable time frame and store it appropriately to ensure its optimal performance and safety.
Will 89 gas hurt my engine?
Using 89 octane gasoline for most cars and trucks usually won’t hurt the engine. In general, the octane rating is a measure of how resistant the fuel is to pre-ignition or knocking. Therefore, using a higher octane fuel typically means that the fuel operates in a more controlled manner, with less chance of pre-ignition.
Most modern vehicles, however, are built to run on regular 87 or 88 octane gasoline. Using a higher-octane gasoline may not provide any noticeable benefits to the car’s performance or fuel economy. While using 89 octane gasoline won’t necessarily harm your engine, it will lead to unnecessary expenses that can add up over time.
Switching to a higher-octane gas, such as 91 or 93 octane, is typically recommended only for high-performance vehicles or for those with high compression ratios. Using a lower-ranked gasoline in those cars can cause knocking and pre-ignition, which can ultimately damage the engine.
Using 89 octane gas is unlikely to cause any harm to an average vehicle. However, since most cars and trucks are designed to run on regular unleaded gasoline, using 89 octane can lead to unnecessary expenses. It is always important to check your car’s owner manual to determine the most recommended gasoline octane rating for your particular make and model.
What gas gets the mileage?
The gas that provides the best mileage depends on various factors. In general, gasoline that has a higher octane rating may offer a slightly better fuel economy than gasoline with a lower octane rating. However, using gasoline that has a higher octane rating than your car’s engine requires may not improve mileage and can even decrease fuel efficiency.
Additionally, factors such as driving habits, vehicle condition, and road conditions significantly affect mileage. For example, driving at higher speeds, accelerating and braking abruptly, and carrying extra weight in the car can decrease fuel efficiency. Regular maintenance, such as keeping the engine properly tuned and ensuring the tires are correctly inflated, can help boost fuel economy.
Apart from gasoline, other gases such as diesel and compressed natural gas (CNG) also offer good mileage for certain types of vehicles. Diesel engines have a reputation for being more fuel-efficient than gasoline engines, especially for heavy-duty vehicles like trucks. Meanwhile, CNG is a cleaner-burning fuel that is often used in buses, taxis, and other commercial vehicles.
CNG-powered vehicles can offer excellent mileage and lower fuel costs over time.
The gas that gets the best mileage depends on several factors, including the vehicle type, engine requirements, driving habits, and road conditions. Using the appropriate fuel and maintaining the vehicle can help improve fuel efficiency, save money on fuel costs, and reduce environmental impacts.
What grade of gas is for my car?
The type of gasoline that is suitable for your car largely depends on the make and model of your vehicle, as well as the engine’s specifications. Therefore, to determine the most appropriate grade of gas for your car, you should refer to the owner’s manual provided by the manufacturer.
As a general guideline, most modern cars run on unleaded gasoline with an octane rating of 87. Such fuel is commonly referred to as regular-grade gasoline and is available at most gas stations. This type of gasoline is usually suitable for most cars that have a standard engine and do not require a higher octane rating.
However, some cars, particularly higher-performance cars, require a higher octane rating of 91 or 93. This is because high-performance engines typically have a higher compression ratio, which can cause pre-ignition or engine knocking when using lower-octane fuel. In this situation, using higher-octane fuel can prevent damage to the engine and ensure optimal performance.
It is essential to note that using a higher octane rating than what is recommended for your car does not necessarily enhance performance or improve fuel economy. In fact, using a higher octane rating than what is necessary can result in wasted money, as these fuels are typically more expensive.
The best way to determine the appropriate grade of gasoline for your car is to refer to the owner’s manual or consult a professional mechanic to ensure optimal performance and avoid potential engine damage.
What is the gas to put in your car?
The type of gas to put in your car depends on the type of engine in your car. Most gas-powered cars in the U.S. use unleaded gasoline with an octane rating of 87. This is a type of gasoline that is formulated to work best with most engines, and it is widely available at gas stations across the country.
However, some high-performance cars require higher octane gasoline (usually 91 or 93) to operate at peak performance levels.
It is important to always look at your car’s owner’s manual to see what type of gasoline is recommended for your specific make and model. Using the wrong type of gasoline can cause damage to your engine, and lead to various performance issues such as reduced fuel economy, increased emissions, and decreased power.
Another important factor to consider is the ethanol content of the fuel you are putting in your car. Many states require gasoline to contain a certain amount of ethanol, which can range from 10-15%. Ethanol is a renewable fuel that is made from corn and other crops, and it can help reduce petroleum use and greenhouse gas emissions.
However, ethanol can also have some negative impacts on engines, particularly older engines or engines that are not designed to run on ethanol.
Finally, it is important to consider the quality of the gasoline you are putting in your car. Gasoline that is contaminated with water or other impurities can cause engine damage, reduced performance, and potentially dangerous driving conditions. In general, it is best to purchase gasoline from reputable gas stations that have a good track record for quality and cleanliness.
The gas to put in your car depends on your car’s engine type, as well as any recommendations in your car’s owner’s manual. Paying attention to ethanol content and gasoline quality can also help ensure that your engine runs smoothly and efficiently.
Why is 89 gas better than 87?
89 gas is better than 87 gas because it has a higher octane rating. Octane rating is the measure of the fuel’s ability to resist knocking and pinging during combustion. Knocking and pinging occur when the air-fuel mixture ignites before it is supposed to, resulting in a combustion that is not as smooth and efficient as it could be.
When the fuel has a higher octane rating, it burns more slowly, allowing for a more complete combustion process. This results in a smoother running engine with better performance and fuel efficiency. It also reduces the chances of engine damage caused by knocking and pinging.
Moreover, many high-performance engines require higher octane fuel to achieve their optimal performance. If such engines are not able to get the required octane fuel, they may suffer from power loss, poor performance, or even engine damage.
89 gas is better than 87 gas because of its higher octane rating, which results in better engine performance and efficiency, reduced risk of engine damage, and is required for some high-performance engines to run at their best.
What happens if I put 87 instead of 89 in my car?
If you put 87 octane gasoline instead of the recommended 89 octane gasoline in your car, it could result in some problems. Octane rating is a measure of a fuel’s resistance to pre-ignition or engine knocking. High-performance and turbocharged engines require higher octane fuel because high compression engines are more likely to knock or pre-ignite with lower octane ratings.
When you fuel your car with lower octane fuel, your engine’s computer might adjust the engine’s timing to prevent engine knocking or detonation. This adjustment may result in reduced performance, fuel economy, and power, making it harder for your car to perform optimally. Your car’s Engine Control Unit (ECU) needs to detect a knock before it can initiate advance spark timing retardation.
If the ECU doesn’t pick up the miss, your engine’s performance will be affected.
Over time, it can also cause damage to your engine. The knock sensors are responsible for detecting an engine knock, and when they work too much, they can overheat and get damaged. If the knock sensor fails, the engine can begin to knock on a consistent basis.
In short, putting 87 instead of 89 octane gasoline in your car might not cause immediate damage, but it can lead to reduced performance and potentially long-term damage to your engine. It is always essential to use the recommended gasoline with the correct octane rating for your car to ensure optimal performance and longevity.
Do you get better gas mileage with 87 or 88?
The octane rating is a measure of a fuel’s ability to resist “knocking” or detonation during combustion. The higher the octane rating, the more resistant the fuel is to knocking, which can occur when the air/fuel mixture in the engine cylinders detonates prematurely. Knocking can result in reduced engine efficiency, power output, and fuel economy, among other problems.
Premium gasoline typically has an octane rating of 91 or higher, while regular gasoline usually has an octane rating of 87 or 88. Unless a vehicle’s manufacturer requires premium fuel or if the engine has a high compression ratio or turbocharging, using regular fuel is usually sufficient and will not adversely affect performance or fuel economy.
In fact, using a higher octane fuel when it is not necessary may actually decrease fuel economy, as premium fuels typically have a different chemical composition and burn more slowly, which can negatively impact combustion efficiency and result in reduced mileage.
Therefore, in general, there is no advantage to using 88 instead of 87 as the difference in octane rating is unlikely to affect fuel economy or performance. However, it is always best to consult with the owner’s manual or with a qualified mechanic to determine the optimal fuel type and octane rating for a particular vehicle.
Which gas is better 87 89 or 93?
The better gas between 87, 89, and 93 depends on the individual’s car manufacturer’s recommendation and the driving conditions. Gasoline with a higher octane rating, such as 89 and 93, is designed for high-performance cars that have engines with higher compression ratios. On the other hand, gasoline with an octane rating of 87 is intended for regular cars with standard engines.
If your vehicle only requires 87 octane gasoline, there is no need to spend extra money on higher-octane fuel. Using 87 octane fuel in high-performance cars can decrease their fuel economy and power output. Conversely, using high-octane fuel in standard engines designed for regular unleaded gasoline may waste money since higher octane fuel is not necessary for such engines.
Therefore, before deciding which gasoline to use, one should always consult their owner’s manual for the recommended fuel. In some instances, manufacturers urge the use of top-tier gasoline, which frequently includes higher-octane levels than what owners might have selected otherwise.
Furthermore, driving conditions also play a role in determining which gas is better for your vehicle. For example, if you have to commute long distances, drive in heavy traffic, or go up steep hills frequently, higher octane gasoline may be more appropriate since it can minimize engine knocking and decrease engine wear and tear in such situations.
The better gas between 87, 89, and 93 relies on the make and model of the vehicle, driving conditions, and the manufacturer’s recommendation indicated by the owner’s manual. It is necessary to follow the recommended fuel type to guarantee the vehicle’s optimal performance and prevent damage to the engine.
