Regular or Premium Gasoline Required?

I was going to say the same thing last week, but knew most here would say it's placebo effect.
Smooth and more responsive almost immediately.
Costco fuel 93 seems to be worth it.

Ok, you guys convinced me. I will fill up my next tank with 93oct and see if I feel any difference.
Just curious though, what exactly feels smoother? Does the engine seem smoother or the way
the transmission is shifting.
Personally I have no problem spending the extra money if there truly is a difference. To be honest I am
Suprised that an engine with this compression ratio is tuned for 87oct.

Hi Everyone,
Just picked up my RX450h this weekend. I'm all about following what the manufacturer recommends. There is a clear sticker on the inside of the fuel door that says "premium unleaded fuel only." I plan on following these guidelines and using Costco's premium fuel.

Well curiosity got the best of me so I have been using 93oct gas to see if I can notice any difference. As of now none of the annoying characteristics have changed. Still lugs and drones from the 4th to 5th gear switch. However on more than one occasion when the car was lugging I could swear I heard the engine knocking. That was on 87oct, I'll see if it happens again with the premium gas.

After 3 tanks of premium (91) and several hundred miles of driving, this is what I noticed in the RX350:
-engine runs smoother, less vibrations
-when accelerating, the "drone" many people mention is almost eliminated
-hesitations seem less; engine is more responsive, but acceleration is the same (no noticeable power increase).
I'll switch back to regular (87) after this tank and run it a few weeks and see if the things I noticed were real or not.

I am having very hard believing such reports. If someone filled up the tank for you (and you had no idea what was in the tank) and did it several times, and collected your impressions then perhaps I would be a believer. By the way, results might be very surprising from such 'blind' tests.

Just use what ever makes you happy.

2020 RX f sport octane requirement
Does anyone know if the 2020 RX f sport requires premium gas? I’ve read where regular unleaded can be used in the 2019 RX f sport but I was watching a video recently and the reviewer stated that the manufacture recommended premium in the 2020.

Hello Oldloanman,
I just bought a RX 350 F 2020. The day I have pickEd it up from the Dealership, the person who walked me through the features of my SUV recommended me specifically that I should use only the Regular gasoline not the premium. He stated that otherwise some of the elements of its engine will get damaged. In fact, I have found a link in which it talks about the recommended fuel for Lexus. Please see the attached link:

Nevertheless, it is always recommended to ask this question to you Dealer.
I hope it helps, greetings.

Thank you for the information. I’ve ordered a 2020 f sport which hopefully will arrive this week. My current ‘13 RX f sport uses regular unleaded and each RX since 2013, except the hybrid, has used regular unleaded. It just didn’t make sense that the manufacturer would recommend premium now. Thanks again!
