Does Lexus RX hybrid take regular gas?
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.
For most Lexus models the answer to this question is yes.
So, do you have to put premium in a Lexus? The answer depends on the specific model you’re driving. Some vehicles like the 2022 Lexus ES can utilize regular 87-octane fuel whereas other models like the 2022 Lexus GX require premium 91-octane fuel to provide you with optimal performance on the St. Petersburg roads.
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, so the Lexus gas type depends on the model.

What happens if I accidentally put 87 instead of 91?
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.
Can you mix 87 and 91 gas?
Is it bad to mix premium and regular gas? Well, not necessarily. If your car requires premium to run smoothly, but you aren’t able to find a station with premium gasoline, it won’t hurt to top off with regular gasoline. You do want to avoid running on regular gasoline for extended periods of time.
With that said, you’re probably asking yourself, “Does Lexus require premium gas?” For most (but not all) of the Lexus lineup, the answer to that question is yes. Most Lexus models require you use at least 91 octane (premium) gasoline, while there are a few that can use 87 octane regular unleaded.
