What kind of gas does the Lexus HS250H take?
The Lexus HS250h runs on regular unleaded gasoline (87 octane). It’s a hybrid vehicle that combines a gasoline engine with an electric motor, and premium fuel is not required for normal operation.
Fuel type and octane requirements
In daily use, the HS250h uses gasoline as its primary fuel source. The recommended octane is 87 (regular unleaded) in markets like the United States. Premium fuel is not mandated for ordinary driving.
Notes on performance and fuel choices
Using higher-octane fuel (premium) does not typically provide a meaningful performance or efficiency gain for this hybrid. If you experience knocking or unusual engine sounds under heavy load, you may consider higher-octane fuel, but for everyday driving 87 octane is generally sufficient.
Key fuel facts for quick reference:
- Fuel type: Gasoline (regular unleaded)
- Minimum octane: 87 AKI (regular octane)
- Premium gasoline is not required for normal operation; higher octane offers no guaranteed benefit for this hybrid
In summary, the HS250h is designed to run efficiently on regular gasoline, aligning with other Toyota-Lexus hybrids of its era.
