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.
Does the Lexus RX 350 take regular 87 gas?
Do I Need to Put Premium Gas in the RX? You must only use unleaded gasoline in the RX, with an octane rating of 87 or higher. This means the Lexus RX does not require premium gasoline, as the premium octane rating is 91 or higher.
What happens if you accidentally put 87 instead of 91 in a Lexus?
If you put lower-octane fuel into your high-octane vehicle, whether by mistake or to save money on gas, you'll probably notice the effects right away: things like poor fuel economy, reduced acceleration, and spark knock, which sounds like a high-pitched pinging or rattling noise.
Which Lexus can use 87 octane?
If you're looking for a Lexus that runs on 87-octane fuel, there are a few options in the lineup: Lexus ES (ES 250, ES 350, ES 300h) Lexus UX (UX 250h) Lexus NX (NX 250, NX 350, NX 350h)
Is it better to use 87 or 89 gas?
89 is mostly for older cars that can run significantly better on higher octane, but it isn't really that popular anymore. 87 is the standard for basically all modern vehicles.
