As a general rule of thumb, you should always use the octane rating recommended by the manufacturer of your vehicle. If you experience any knocking or pinging noises from your engine, you may want to try a higher octane fuel to see if it resolves the issue. However, if your engine is running smoothly with the recommended octane rating, there is no reason to switch to a higher octane fuel.
Here are some additional reasons why it may not be worth it to use more than 85 octane fuel:
* Higher octane fuel is more expensive. The higher the octane rating, the more expensive the fuel will be. This is because higher octane fuel requires more refining and processing, which adds to the cost of production.
* Higher octane fuel can actually decrease fuel efficiency. Higher octane fuel has a lower energy density than lower octane fuel. This means that you will get fewer miles per gallon when you use higher octane fuel.
* Higher octane fuel can cause problems with your vehicle's engine. Using higher octane fuel than recommended can damage your engine's oxygen sensor and catalytic converter. This can lead to costly repairs down the road.
In conclusion, there is no real benefit to using higher octane fuel than what is recommended by your vehicle's manufacturer. In most cases, it will simply cost you more money and provide no additional benefits.
