Regular gas 350h
I just ordered a 2022 nx 350h. I know that we are supposed to use premium gas for the nx 350h. However, I've also heard reviews say that the engine is the same as the Rav4 hybrid, just with the stronger RX electric motor. If the engine is the same, why can't we use regular gas just like the rav4 hybrid does?

Per the NX 350H manual, premium is recommended, not required. For the NX 350, premium is required.

I downloaded the manual. You are right it can take 87 gas. It's the rav4 engine with the more powerful RX electric motor so it just makes sense.

The ECU is tuned differently to the RAV4, where the expects the recommended RON.

"Recommended to use premium unleaded gasoline with octane rating of 91 (Research Octane Number of 96) or higher for optimum engine performance. You may use unleaded gasoline with octane rating of 87 (Research Octane Number of 91). In this case, engine performance may be decreased.
Use of octane rating unleaded gasoline with an octane rating lower than 87 may result in engine knocking. Persistent knocking can lead to engine damage."
So it looks like premium is not required.

You can use 87 octane. I am leaning towards using 87 when my 350h arrives

I would stick with premium. Yes premium is more expensive and it's expected when you buy a Lexus. Degrade performance and possible engine damage could in fact cost more if it happens.
It also depends on how much you drive and how frequent you fill up. Also if you are leasing the car, sure regular gas shouldn't matter much... Just leave it to the next owner to deal with.

Already discussed - see thread in message response
Not required on Lexis 2022 NX 350h, regular will work fine. This has already been discussed ad Infinitum.
Yhis is one of the better, more complete discussions on grade of gasoline required: https://www.clublexus.com/forums/sho...errerid=161523

It is tuned for premium. The US user manual is written poorly and confusing people. Other countries user manual is much more clear.
The question here is not if it can run on lower octane. Of course it can.
The question is what it should run on to get the optimal performance. And the answer is premium. No discussion thread is going to change what is published by Lexus. If one wants to run on regular, buy a RAV4 hybrid and not an NX350h.

The fine print, on page 724 of the owner's manual, states:
"Recommended to use premium unleaded gasoline with octane rating of 91 (Research Octane Number of 96) or higher for optimum engine performance. You may use unleaded gasoline with octane rating of 87 (Research Octane Number of 91). In this case, engine performance may be decreased.
Use of octane rating unleaded gasoline with an octane rating lower than 87 may result in engine knocking. Persistent knocking can lead to engine damage."
So it looks like premium is not required.

As someone once said when I had a similar question on reg. vs premium for my 2010 RX 450h. You pay good money for a quality hybrid. Why worry about a few dollars more at fill up.

Use regular and enjoy the savings on a nice steak dinner.
