Used regular gas in last six vehicles that required premuim or recommended it and logged over a million miles. Noticed no difference in gas mileage or horsepower and of course zero engine problems. Want another opinion go to YouTube and search regular gasoline versus premuim and watch two clips one from Consumer Reports and one from CBC News.

There is, of course, a huge difference between using regular in a car that recommends using premium gas vs using regular in a car that absolutely requires it. Hard to tell from that anecdote how many cars actually prospered that required high test. It's no secret that cars that recommend premium don't require it, Consumer Reports has noted this, but I've never seen them say you should use regular in a car that requires premium.

Personally, i run the recommended 91 in our RX450h+, but I'd have no problem running 87 if 91 wasn't available. Sure, it's not necessary, but I believe Lexus optimized it for 91, so that's what I run.

I guess if some want to get by on the cheap they can try. I wouldn't.

89 octane
I’ll admit I know little of car things other than I like Lexus. We are looking at our 4th one now and it’s a 2023 RX350 Premium.
We’ve just started looking as some 2023’s are coming out used.
if we purchase it and do some traveling, can 89 octane be used instead of 91.
I appreciate your responses.

There is a rather large fuel reserve, so even if you get the gas gauge to ZERO you still had ~5 gallons of 93 in the tank.

If you want to run lower octane fuel, I'd recommend against the RX350 and suggest the RX350h instead.

That’s why I’d be concerned buying a used car that requires premium. People either can’t read or don’t care.
One of my cars recommends premium, I put in Shell midgrade or Costco premium.

Every forum I’ve been on, the same stuff is asked. I find it wierd that 80 posts in, the same question is being asked. How many times do you have to be told required means REQUIRED.

p.s. my Volvos (turbos) all recommended premium gas but did not require it, even the general manager of the dealership said to use regular, and I always did....

I've read on forms ppl that lease and know they're not keeping the car won't take time to change the oil and put whatever fuel that will run in it.
It's always a gamble unless you look up the maintenance records, just like you would when checking for accidents. I believe ppl on this form actually care about their vehicles.
