According to the search results, most Lexus models require premium gas, but there are some exceptions. The Lexus UX, US Hybrid, NX Hybrid, RX, ES, and ES Hybrid models require only 87-octane (regular) gas, while all other Lexus models require premium gas.
Therefore, it is important to consult the owner’s manual or check the specific model’s requirements to determine whether premium gas is required for a Lexus LS 400. If the manual states that premium gas is required, it is recommended to use it to avoid potential engine damage and to maintain the warranty.

What happens if you put regular gas in a Lexus?
Use of unleaded gasoline with an octane rating lower than what is listed for your model year vehicle could potentially result in engine knocking. If the octane rating used is less than required, damage to the engine may occur and which could void the vehicle warranty.

- 2022 Lexus ES 250 Fuel Requirement: Regular 87-octane unleaded.
- 2022 Lexus ES 350 Fuel Requirement: Regular 87-octane unleaded.

If it’s running, shut it off. Get it towed someplace that can remove and drain the fuel tank. But as long as you’re sticking with good old gasoline—octane references the likelihood of mistimed combustion. Basically, higher octane ratings mean there’s less of a chance that combustion will occur at the wrong time.
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.
What kind of gas does a 1995 Lexus LS400 take?

First, using too low of a grade of gas can lead to engine knocking, which can cause long-term damage to your engine. And second, using regular gas when you should use premium could void your warranty, meaning you would have to pay for any costly repairs out of your own pocket.
