With an $11 OBD2 Bluetooth reader and a free app, you can read how many misfires by cylinder your 5.7 has during a trip.
Then you can determine, based on your truck, your elevation, and your driving style, if a lower octane rated fuel is appropriate.

If what you’re saying is doable, then this is by far the most intelligent answer I’ve read on this topic thus far.
I've been on here forever and have owned land cruisers since 1998. I find it funny that we drive 90,000-100,000 vehicles yet bitch over the extra .30 cents per gallon It cost (in my area) for premium gas. If you drive 100,000 miles divide that by 15 miles per gallon, that 6,666 miles, times that by .30 cents that’s 2,000 bucks it takes on average 6 years to drive that many miles so divide 2,000 bucks by 72 months, that’s 27.77 per month. Everyone talks about saving money on gas (driving a full time 4wd 5.7 v8) while putting on heavy ass bumpers that have horrible aerodynamics (kills mpg), throw on some bigger heavy ass mud tires or at tires (kills mpg), put on a lift, further more killing aerodynamics (kills mpg) put on a roof rack that is not very aerodynamic (kills mpg) add like 1,000lbs worth of gear (kills mpg) but let’s save money on gas.... funny, just funny.You obviously haven’t been here long enough
tfl did a towing test with the land cruiser and the lx570 going up Ike gauntlet. the lx570 made it up the hill a full 45 seconds faster why?? Who knows it just did. I would like to see a dyno on both the lx570 and the land cruiser seeing power through out the entire power band. Then we can scientifically see the difference. I have towed with both the land cruiser and the lx570 for some reason I feel the 570 has more power up the hills. That being said the 570 is the wife’s suv, I’m going to get me a 200, throw on some 17’ wheels, ko2’s an ome lift, with some slee sliders and put in 88 ethanol free in that one. Not look at the mpg’s focus on making more money and enjoying it.

I was specifically speaking about your comment about nobody debating oil weights and viscosities.
There are multiple threads on the subject.

In Jacksonville Florida it’s $.80-$.90 a gallon difference between regular and premium that’s about $80-$90 more per month. If it’s not gonna damaging anything why wouldn’t I want to save $80-$90 a month?

Has somebody gone over 150,000 miles in their LX 570 on regular gas with no problems??
Yes. Me. And over 400k miles on my LC100 that also requires premium fuel. And 200k and 125k on my son’s and my wife’s Lexus RX hybrids. Zero issues. I do have a Lexus SC430 that has only had premium but then again i drive that car pretty hard and have for 18 years. But i doubt it would have had a problem with regular either.
remember - all of these vehicles are also owned by people living jn rural areas that may have access to 87 or even 85 only. The car engines dont get ruined. Our Toyotas are not Ferraris. They aren’t that picky.
So why is the SC430 the exception when it comes to premium? Lexus was correct in saying premium for THAT car but not others? It contradicts your entire post.
No reason other than it makes me feel special
. i put less than 3k miles on the SC a year. I drive my other vehicles about 40k miles a year often far from anything over 87 octane.
premium for me....gas prices way down and my shell card gives me another $.05 off per gallon!!

Coronavirus took care of the problem with high priced premium fuel I guess this threads done
hahahaha don't give toyota that much credit. Have you seen techstream...that's like from when computers were invented. There are way worse issues with modern gasoline than octane rating.
This is the same 5.7 that goes into every Tundra that runs on 87.
I have LX and put 35k miles of towing with reg. gas. 10-12mpg towing 4k lbs and 15-16mpg on highway.
EDIT: I'm kinda curious now, I'm gonna fill up premium when I need to drive and see if there is any noticeable difference (I expect none).

Because it has a V8 that actually does require premium. You can drive that 4.3 on regular but you lose noticeable power. I've used regular on my LS430 before, it felt sluggish.
The 5.7 needing premium is just pure Lexus marketing garbage. I've had my truck months now, not a drop but 87 I use and I'm almost 100% sure PO used premium.
Engine hasn't blown, nothing is knocking. The truck hauls ass. I get 20MPG highway, lol. All on 87 octane.
Throwing my hat into the ring.
Im all for following OEM recommendations but im not a child and I know how things work.
There are instances where having appropriate knowledge on a subject exposes variables you would otherwise overlook and it may be best to concede to your ignorance.
HOWEVER, that is often not the case. And it certainly is not the case here due to the overwhelming evidence.
Weve had multiple conversations about oil weight and fuel. In regards to the former, im not putting 0W-20 in my engine.
Sorry but we have multiple pieces of information to contradict the need for that. (CAFE, 3UR specs worldwide being identical running range of oils, common sense, personal experiences etc.) I don't care what oil you choose to run, as we should all be running diffrent weights if you understand the basics involved.
The world is a big ****ing place... Some people live in Phoenix for crying out loud where last year it was above 100 for half the GD year. If you're using 0W oil, you may as well run it dry in the summer.
"Phoenix broke records for the most 95-degree days (172), 100-degree days (145), 105-degree days (102), 110-degree days (53) and 115-degree days (14) in a year with daily heat records being shattered 18 times throughout 2020"
Im not saying to def run a 0 or 50W oil because you are looking at your engines operating temp not the ambient. Although ambient will surely make enough of a difference (ESPECIALLY AT START) that you REALLY need to consider sources outside of your USA Toyota manual for guidance on whats right for you. We are also lucky to have an oil pressure gauge and I encourage everyone to use and experiment.
ANYWAY to get back to fuel there is just so much evidence that it doest matter at all what you run that you would have to be crazy not to be okay with it.
One small example is that i cant even get 93 in California, i can only get 91. Those 2 octanes are absolutely meaningless. Why would they sell the same car in Cali without accounting for this if -2 octane rating is detrimental? Is the LX more reliable (or any care for that matter) in state with 93? Not at all. And if you have the data to show otherwise please do. There is also the LC with an identical powertrain using 87. Is that less reliable? No. If I can safely use 87, 91, and 93 on the exact same vehicle then we can certainly run 89 as well in this platform without issue. Someone will have to prove to me that the ECU is adjusted for this from the factory for me to even care. I doubt there is even any difference between the two ECUs in the first place other than year to year updates.
On top of all of that obviousness, most people dont even realize they are running different ethanol concentrations from station to station. Most people don't even know about summer and winter gas. There are already a host of different additives that you are running that are changing all the time including octane on interstate road-trips.
Ive never experienced one iota of difference between fuel grades on my many cross country tours from NYC to LA with my 100 (towing and fully loaded through elevation) or now 200. It just does not care what you give it. Believe me Ive had cars that were very sensitive to fuel leading to multiple issues but this is not one of them. Im sure the 300 series will change all of that though. Forced induction makes fuel and timing that much more critical and it will probably cause issue in some way or another for the 300. (sorry i had to take another s*** on the 300 but it just sucks, fight me)
I understand there is more complexity involved with combustion and everything surrounding that, but with the level of crap gasoline here in the states, and abysmal quality elsewhere i doubt there is any need for concern because we simply have not seen anything happen to think otherwise after the millions or billions of miles out there. I dont think ISIS is running premium and the fuel in the middle east is notoriously bad. I doubt they use anything OEM or OEM spec actually.
Point is this entire vehicle is designed from the ground up to be robust and just because there is a legal disclaimer in the manual does not make it a reasonable assumption. All that being said I am open to learning more and i run premium 93 here in TX because i can. If one of the forum elders wants to rip me a new one please do, but unless you bring direct contradictory evidence, im not interested.
I just want to add this since its a peripheral issue and im seeing it on a daily basis everywhere in my life:
Empirical evidence matters, first hand direct experience is not "anecdotal evidence", these obsessions with academic dogma are whats driving a lot of our societies problems today and is leading to a high level of intellectual regression. Appeal to authority is not a valid interpersonal tool for debate.
We can not let our children and future generation today believe that truth is institutional. If you understand the first thing about people and their inherent biases and motives you will gain the wisdom to understand that authority is fallible just as much as any individual.

I live in Alachua county. Used to fill up with premium all the time and was able to get 13.5 - 14 mpg mixed city/highway. After using 2 tanks of regular (had no issues) and reading all the regular/premium discussions here I came to the conclusion there is really no difference between these two. Just for fun decided to switch to Wawa's non-ethanol gas 89 octane and I love it. Cost a bit less than premium but I get 14.8 mpg - 15 mpg same driving style. Also, I have noticed the truck got a bit more responsive on non-ethanol gas as well.
As somebody mentioned here 3UR-FE is not a high compression engine and does not really require premium gas. But hey this is you car you can use whatever you like LX not gonna have any problems with neither.
It is interesting to call this a low compression engine, the octane is just right for the compression. Displacement and Compression Ratio - https://autocalc.onlinedyno.com/displacement.php
- This is massively higher compression than the old street gas v8 engines because of the many, many design improvements. The compression and octane rating is right in line with non-boosted aluminum V8s that have a real towing capacity.
- It also has a pretty sophisticated valve system...which also influences octane needs beyond what a static compression would indicate.
Exactly. Selective comprehension to arrive at a conclusion? Fail.
