Somewhat, but really, Toyota is a very smart company, and they take everything into consideration. I think it's just that the ECU is smart enough to handle 87 octane under any circumstances. If they didn't take that into account I think they would be remiss.

I’m not saying the car can’t handle regular, I’m saying it’s MOST likely a bad idea to run regular on a car tuned for 91 octane for a long time.

.I'm just stating the facts:
- Using gas with an octane rating of 87 isn't going to damage the engine
- Toyota recommends 91 because they use HP numbers to help sell cars
- There is good evidence across multiple data sets to suggest that you will get an increase in power at certain times if you use 93
- There is good evidence across multiple data sets to suggest that you'll get better gas mileage with higher rated octane gas
Pretty simple.
If you can't afford premium fuel, buy a TOYOTA! --------> https://www.clublexus.com/forums/is-...gular-gas.html

Current gas price in my area.
Regular (87) = 2.55/gallon
Premium (93) = 2.95/gallon
Using premium
I fill my tank every month (2.95 x 17.4gal = 51.33/month ) x12 = $615.96 / year x 10 years = 6,159.60
Using regular (2.55 x 17.4 = 44.37/month) x 12 =532.44 / year x 10 years = 5324.40
Difference of $83.52 a YEAR!
and
835.20 in 10 years
Difference is not even enough to buy tires for 10 years
C'MON MAN!

Not everyone is like you, drives their car like you, or lives in your area. The prices will massively fluctuate within 3 years as well.
I shoot for Mecum auctions and drive mostly for a living (about 1 hour shooting for every 5 hours driving), and I can tell you it makes a big difference over the long haul.
Just keep doing what you're doing, no one is trying to convince you otherwise.

Completely agree, but also consider putting 87 will drop MPG so will also end up putting more gas which equals to more $.
... Why do I have a feeling we will never meet an end to this lol.

I think there is a discussion like this on many forums, probably once every few months. To each their own I say, as long as they know the facts, like literally using 87 octane rated gas will not damage your engine, even if the manual says it might. It has literally never happened on this engine.

You're right, there is some efficiency loss under load under certain conditions, but on the highway at cruising speed at what, 2,000 rpm? I don't think it's much. Maybe that's a better argument for in-town driving.

Oh, and looks like this engine is capable of having issues due to using lower octane after all.

25 years of anecdotes - that's just a lot of anecdotes. (Granted, this is just one story, but it's a story nonetheless. There's lots of discussion in that thread about this same subject, by the way - with lots of sifting through facts and hearsay - read: dealership recommendations.)
The fuel filler door says "PREMIUM UNLEADED ONLY", but I reckon that's just not good enough for some.

If the answer is no, then there is simply no discussion to be had.
And even if the answer was yes, what, once? Ever?
I mean, come on bro, you're literally grabbing at ghosts.

In a thread in the NX forums, two 8AR-FTS engines were broken down at 60k miles probably due to misfiring caused by carbon build-up on the valves, however it is unclear if less than 91 gas was used or is at fault.

I agree with that, I just feel like if it were a real issue we'd see a lot more of this sort of thing, and we just don't. Maybe something else was wrong with the car? Maybe he was driving it like he stole it constantly, running 87? Who knows?

I still don't think you have a strong argument. I would take an educated guess and say 98% of drivers driving Lexus' that require premium do so. You want proof of engines that were destroyed due to running 87. You won't hear about them because people don't run 87 lol.
