Can you mix 87 and 91 gas? This is a question with a simple answer: yes, you can mix 87 and 91 gas, however, it is not recommended. In order to understand why, it helps to understand the differences between the two types of fuel.
87 gasoline is a type of unleaded gasoline with an octane rating of 87. This fuel is typically used in cars with older engines or vehicles that don’t require higher octane fuel. 91 gasoline, on the other hand, is a type of unleaded gasoline with an octane rating of 91. This fuel is typically used in vehicles with higher-performance engines, such as sports cars.
The difference between the two fuels lies in their octane rating. 87 gasoline has a lower octane rating, meaning it has a lower resistance to pre-ignition. This means that it is more likely to ignite prematurely during combustion. 91 gasoline has a higher octane rating, meaning it has a higher resistance to pre-ignition.
When you mix 87 and 91 gas, you are essentially diluting the octane rating of the fuel. This can cause a variety of issues in your engine, such as engine knocking or decreased engine performance. In addition, mixing fuels can change the chemical composition of the fuel and cause your engine to run less efficiently.
Because of these potential issues, it is not recommended to mix 87 and 91 gasoline. If you need to use higher octane fuel in your vehicle, it is best to purchase fuel with the octane rating indicated in your owner’s manual. If your vehicle requires 87 gasoline, it is best to purchase fuel with an octane rating of 87.
Should You Mix 87 And 91 Gasoline?
Often, it is hard to know which type of gasoline to choose when you pull up to the pump. There are several types of gasoline available, including 87, 89, and 91 octane. If you’re wondering “can you mix 87 and 91 gas?”, the answer is yes, but you should know what you are doing.
Mixing 87 and 91 gas properly can actually help improve your car’s performance and will not damage your engine. However, it is important to know how much of each type of gas to use. Generally, you should use more of the higher octane fuel, such as 91. As a rule of thumb, aim for around 70% of the higher octane gas and 30% of the lower octane gas. This ratio will provide you with a fuel blend that is close to the average octane rating.
When you mix 87 and 91 gasoline, you may experience an increase in power, better fuel economy, and smoother acceleration. It is also important to note that not all cars will benefit from this mix. If your car is designed to run on a specific octane rating, it is best to stick to the manufacturer’s recommendation.
In terms of cost, mixing 87 and 91 gas can be a good way to save on your fuel costs. 91 octane gasoline typically costs more than 87 octane gasoline, so when you mix the two, you can get a fuel blend that is closer in price to 87 octane.
In conclusion, mixing 87 and 91 gas is not necessarily bad for your car, and it can actually improve performance in some cases. However, it is important to know what you are doing and to follow the manufacturer’s recommendation if you want to get the best results.
87 Octane VS 91 Octane
| Octane Rating | Cost | Performance |
|---|---|---|
| 87 | Cheaper | Lower |
| 91 | More Expensive | Higher |
The Pros And Cons Of Blending 87 And 91 Gasoline
87 and 91 gasoline are both grades of fuel used to power vehicles with spark ignition engines. While both grades of fuel have the same octane rating, the difference between them lies in their composition. 87 gasoline has a lower level of volatility and contains fewer aromatics than 91 gasoline, while 91 gasoline contains more and is more volatile.
87 gasoline is typically cheaper than 91 gasoline and is good for most day-to-day driving. 91 gasoline is typically more expensive than 87 gasoline and is ideal for performance vehicles, as it provides better acceleration, more power, and better fuel economy.
Mixing 87 and 91 gasoline is a contentious issue, and opinions vary on whether it is a good idea or not. There are pros and cons to blending the two grades of fuel, which are outlined below:
- It can reduce emissions from your vehicle – blending 87 and 91 gasoline can reduce the level of emissions produced by your vehicle as the blend is more volatile than either 87 or 91 gasoline alone.
- It can reduce the cost of fuel – blending 87 and 91 gasoline can reduce the cost of fuel, as it is cheaper than buying 91 gasoline alone.
- It can improve the performance of your vehicle – blending 87 and 91 gasoline can improve the performance of your vehicle, as it provides more power and better acceleration.
- It can damage your vehicle – blending 87 and 91 gasoline can damage your vehicle’s engine, as the fuel is more volatile and can cause deposits to form on the fuel injectors.
- It can reduce fuel economy – blending 87 and 91 gasoline can reduce fuel economy, as it is more volatile and can cause the engine to work harder.
- It can reduce the life of your vehicle – blending 87 and 91 gasoline can reduce the life of your vehicle, as the fuel is more volatile and can cause more wear and tear on the engine.
Ultimately, whether or not you decide to blend 87 and 91 gasoline is up to you. It is important to consider the pros and cons of blending the two grades of fuel before making a decision. If you do decide to blend 87 and 91 gasoline, it is recommended that you use a fuel stabilizer to help reduce the risk of damage to your vehicle’s engine.
