Lexus RX Hybrid and Premium Gas Requirement
The Lexus RX Hybrid’s gas requirements depend on the specific model and year. Here’s a breakdown based on the information gathered from various sources:
– Lexus RX 450h: The 2021 Lexus RX 450h requires premium gasoline. However, for the 2011 Lexus RX 450h, some users have reported using mid-range or “Plus” gas (89 octane) without noticeable performance deterioration.
– Lexus RX 400h: Some users have reported that the Lexus RX 400h does not require premium gas, and using regular gas may result in a slight decrease in fuel efficiency without noticeable performance differences.
– Lexus RX 350: The 2020 Lexus RX 350 does not require premium gas and has a recommended minimum octane rating of 87 for fuel. This is consistent with the general recommendation for the RX 350 model line to use regular gasoline without sacrificing luxury or style.
– Other Lexus Models: It’s important to note that not all Lexus models require premium gas. For example, the Lexus UX, US Hybrid, NX Hybrid, and ES models require only 87-octane (regular) gas, while all other Lexus models require premium gas.
In summary, while the 2021 Lexus RX 450h requires premium gasoline, the gas requirements for other models, such as the 2011 RX 450h and the RX 400h, as well as the RX 350, vary. It’s advisable to consult the specific owner’s manual for the exact gas requirements of a particular Lexus RX Hybrid model.

As I understood it, the platform and engine in the 350h is the same as the one used in the Rav h model and it runs on regular fuel.

What kind of gas does a Lexus hybrid take?
| Model Year | Model(s) | Recommended Minimum Octane Rating |
|---|---|---|
| 2022 | NX 350h | 91 (recommended) or 87 (minimum) |
| 2021 | GX 460, IS 300, IS 350, LC 500, LC 500C, LC 500h, LS 500, LS 500h, LX 570, NX 300, RC 300, RC 350, RC F, RX 450h | 91 |

Since these engines operate on an 87-octane fuel rating, putting in higher-grade gasoline will not improve fuel economy estimates, nor provide additional power. Your Owner’s Manual will specify which gas to use. MYTH #2 – The hybrid battery only charges when the vehicle is plugged in. False!
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. Of course, you are free to put premium gas in your Lexus RX, as it can provide better performance, but it is not needed.
Can you put regular gas in a Lexus hybrid?
So, if you are wondering “Can I put regular gas in my Lexus?” The answer may be yes. Some vehicles like the Lexus UX 250h can utilize regular 87-octane fuel whereas other models like the 2022 Lexus GX require premium 91-octane fuel.
When it comes time to fill up, the Lexus NX requires premium unleaded gasoline. You should be looking for an octane rating of 91 or higher, to ensure the NX runs efficiently while providing the best possible performance. Any gas used in the NX should not contain any higher than 15% ethanol.
