What kind of gas does a 2024 Lexus ES 350 take?

The 2024 Lexus ES 350 runs on regular unleaded gasoline with an octane rating of 87 or higher. Premium fuel is not required for normal operation. In most regions, fuels with up to 10% ethanol (E10) are compatible, but you should avoid higher-ethanol blends unless your owner's manual specifies otherwise.


Fuel requirements explained


Understanding octane ratings and ethanol content helps ensure optimal performance and longevity of the ES 350’s 3.5-liter V6 and eight-speed automatic transmission. The vehicle is designed around regular gasoline. Higher-octane fuel is not mandated for this engine, and using regular 87-octane will meet the manufacturer’s standard. If you experience knocking or reduced performance, you may choose higher-octane fuel, but consult the owner’s manual first.


Key fuel considerations for the ES 350:



  • Octane rating: 87 octane (regular unleaded) or higher; premium gasoline is not required for normal operation.

  • Fuel type: Gasoline only; avoid diesel or alternative fuels unless specified by the manual.

  • Ethanol content: Fuel with up to 10% ethanol (E10) is typically supported in the U.S.; avoid fuels with higher ethanol content unless explicitly approved in the manual.

  • Performance expectations: Higher-octane fuel will not necessarily improve performance or efficiency on the ES 350; use higher-octane only if knocking occurs or per manual guidance.

  • Regional considerations: Fuel formulations can vary; verify local recommendations in the owner’s manual or with a Lexus dealer if you’re outside standard U.S. spec.


In practice, this means you can fill with standard 87-octane gasoline at most U.S. gas stations, and you should not be required to buy premium for regular driving. If you notice knocking or reduced performance on regular gas, consult a dealer to ensure there are no underlying issues before switching to higher-octane fuel.


Additional notes about the ES 300h hybrid


The ES 300h hybrid model shares the same general gasoline requirements, but always consult the manual for any model-specific notes or regional variations.


Practical fueling tips


To keep the fuel system and engine running smoothly, follow these general guidelines. The following notes highlight the most important practical points:



  • Use regular unleaded gasoline with an octane rating of 87 or higher unless your manual specifies otherwise.

  • Avoid fuels with ethanol content beyond the recommended limit (commonly more than E10).

  • Do not use diesel or alternative fuels in the ES 350.

  • Consider higher-octane fuel only if you encounter knocking or if your region requires higher-octane fuels for certain conditions; otherwise, it is not necessary.


Bottom line: Following these guidelines will help maintain engine performance and fuel economy as designed by Lexus for the ES 350.


Summary


In short, the 2024 Lexus ES 350 is designed to run on regular unleaded gasoline with an octane rating of 87 or higher. Premium fuel is not required for normal operation, and fuels with up to 10% ethanol are generally acceptable. Always check the vehicle’s owner’s manual or consult a Lexus dealer for any model-specific nuances or regional fuel variations.
