Which fuel grade should I use for my Lexus?
When it comes to fueling your Lexus, the recommended fuel grade can vary depending on the specific model and year. In general, Lexus recommends using premium unleaded gasoline (91 octane or higher) for most of their vehicles. This is the fuel grade that will provide the best performance, fuel efficiency, and engine protection for your Lexus.
Understanding Fuel Grades
Fuel grades are determined by the octane rating, which measures a fuel's resistance to premature ignition or "knocking" during the combustion process. Higher octane fuels, like premium (91-93 octane), are less prone to knocking and are better suited for high-performance engines found in many luxury vehicles like Lexus.
Using a lower octane fuel than what is recommended by the manufacturer can lead to engine knocking, reduced power, and potentially even long-term damage to the engine over time. It's important to always refer to your Lexus owner's manual or the fuel information label inside the fuel door to determine the right octane requirement for your specific model.
Lexus Fuel Recommendations
- Most Lexus models, including sedans, SUVs, and coupes, recommend the use of premium unleaded gasoline (91 octane or higher).
- Some high-performance Lexus models, like the Lexus IS-F and Lexus LFA, may require the use of even higher octane fuel (93 octane).
- Lexus hybrids, like the Lexus ES Hybrid and Lexus NX Hybrid, can typically use regular unleaded gasoline (87 octane), but premium is still recommended for optimal performance.
It's always best to follow the fuel grade recommendations provided by Lexus to ensure your vehicle runs at its best and to avoid any potential engine issues down the road.
