Can I use 87 octane in my Lexus?
The short answer is no, you should not use 87 octane fuel in your Lexus. Lexus vehicles are designed to run on higher octane premium gasoline, typically 91 octane or higher. Using a lower octane fuel can potentially cause engine damage and negatively impact your vehicle's performance.
Understanding Octane Ratings
Octane rating is a measure of a fuel's resistance to premature ignition, also known as "knocking" or "pinging." Higher octane fuels can withstand higher compression levels before igniting, making them better suited for high-performance engines found in many luxury vehicles like Lexus.
Lexus recommends using 91 octane or higher fuel to ensure optimal engine performance and prevent potential damage. Using a lower octane fuel, such as 87 octane, can cause the engine to knock or ping, which can lead to long-term issues like reduced fuel efficiency, decreased power, and even engine damage over time.
Why Lexus Requires Premium Fuel
- Engine Design: Lexus engines are engineered to take advantage of the higher octane rating of premium fuel, allowing for increased compression ratios and more efficient combustion.
- Performance: Premium fuel helps maintain the high-performance characteristics of Lexus vehicles, providing better acceleration, power, and overall driving dynamics.
- Fuel Efficiency: Using the recommended premium fuel can help improve fuel economy and reduce emissions compared to using a lower octane fuel.
- Engine Protection: The higher octane rating of premium fuel helps prevent knocking and pre-ignition, which can cause long-term damage to the engine over time.
While it may be tempting to save money by using a lower octane fuel, it's important to follow the manufacturer's recommendations to ensure the longevity and optimal performance of your Lexus vehicle.
What happens if I put 87 instead of 91 in Lexus?
For one, too low grade gas leads to engine knocking, which can damage your engine in the long run. In addition, using regular gas when you should use premium could void your warranty, which will cost you much more than your small savings at the pump.
