Premium fuel required on the RX350?
#46
Hey guys. I originally ordered the NX350h but someone canceled an order for a RX350, so I jumped the gun and got that instead. I'm seeing a ton of debates regarding which fuel type to use. I understand that the 2023 rx350 now has a new turbo charged engine, so does that change the fuel required? I'm from Toronto and regular gas here is 87. I read on a dealers website that the 2022 rx350 can use a minimum of 87. Anyone know if that's the case for the 2023 rx350 as well? I'd rather not spend the extra money on more expensive fuel if I don't have to. Thanks in advance!
Do any of the new RX's take regular gas?
Yes, even though the RX 350H is recommending premium fuel for the best efficiency and power, you can certainly put regular gas in it! However, the gas-only RX 350 and, also, the RX 500H both require premium fuel!Source: https://www.performancelexus.ca/2023...premium%20fuel!

nothing to misunderstand here if one can read. rx350, 350h and 500h are all covered in that one response from lexus

In NJ, dealers don't have gas pumps.

I was looking at the specs for the Toyota Grand Highlander Hybrid Max. Seems to be the same powertrain, but only requires 87 octane and power is only 340 VS 367 for the 500h. 0 - 60 MPH is only a half-second different.

Wonder if that is the difference in 93 octane VS 87?

What type of fuel you use for your regular (non hybrid) RX350
We all know the dealer and user manual says Premium Gas is Required for new 2023/2024 RX 2.4 turbo. however has anyone used regular (87) on their 2023/2024 RX and experienced any issue?
The reason for that is that many ppl says it is required, will void your warranty, will damage engine etc.. BUT I literally know many people that have BMW and Mercedes and user regular gas for 5-10 years and had 0 issue with their car despite BMW and Mercedes Require premium fuel.
I care less about losing a little bit of performance or HP as I am not racing in streets. but at least in Canada, there is big difference in price of gas between regular to premium (20-30 cents per liter - over a dollar a gallon).

I have the hybrid so it doesn't apply but if I had the turbo I wouldn't risk damaging my engine. If you can afford a 60K car, spend the extra $ and get the premium. If its a lease or your getting rid of the car in a few years, then maybe its ok if you don't hear any pinging when accelerating. Will it void your warranty if the engine has an issue?

I have used regular gas for over a million miles on six different cars that either required premium or recommended premium gas. Obviously no engine problems. No knocking problems. Never noticed a difference when I experimented with premium in better gas mileage or better acceleration. However none have been turbos.

Unless you are towing a boat, I am betting that regular is just fine for the turbo. You might lose a couple of horsepower but for the difference in cost from regular to premium . . . let the horse die.
