Pretty much exclusively 85 from Sam's club since it's cheap and right by my house lol
How often do you use 93 octane in your LC? (1 Viewer)

From a monetary standpoint, "extra" octane is a losing proposition.
Use the lowest octane that avoids pinging under load.
Ethanol free? Would be awesome if it was the same price. My tests showed NO difference in MPG, unfortunately.
Great for all my small engines though.

I do a 9 hour drive monthly, and I average 17.1 on the dot on my 100% stock LC200. My most recent trip I tried two tanks of back to back 93 shell and I got 17.6. I didn’t calculate it by hand, just what the computer said to me.
After reading the comments I’m just going to run 87 “top tier” I.e. from shell/chevron gas stations.
Maybe a couple tanks of 93 after an oil change because they supposedly have more additives (to “clean” the engine) and it can’t hurt the engine.
I emailed BP asking why they're not top tier. They responded their fuel ("invigorate") has higher detergent levels than top tier. Basically saying top tier label would be a step down for their current blend.
I've had some bad fuel before in prior vehicles courtesy of no name fuel stations in CONUS. Thankfully not so bad to have to drain the tank and replace fuel pumps, etc. This obviously can happen in chain stations too, but independent testing has continuously shown the discount gas stations have lower detergent levels than their "name brand" counterparts. YMMV.

I noticed I too got better fuel economy running 93 vs 87 octane. I ran the numbers and even with the marginal bump in MPG, the juice wasn't worth the squeeze on price differential.
Two things:
big reason I bought this truck is Toyota port injected engines are traditionally not finicky when it comes to gas and oil. Coming from the turbo direct injection world having to deal with LSPI, caked up valves, carbon deposits, sticky rings, and blow by , the 3ur is a relative sewing machine. It will run on practically anything. And I have to laugh when I see someone clean a “dirty” maf, if you only saw the inside of these Mazda/BMW/VW GDI motors OMG.
Second, i never had to worry about “bad gas” until I bought a car that ran on premium. It was usually on road trips, I’d hit up some station that maybe doesn’t see a lot of premium customers so the tank ends up being half full of water. Not as much of a worry with regular since it’s so much more popular.

Headgaskets gonna blow if you don't use 93

Depending on what someone means by “take advantage”, testing shows that may not be the case.
Regular VS Premium - let’s put an end to an ongoing debate?
I read many informative posts on this site, some scientific and some speculative but truly nothing very conclusive. Even emails to Toyota drew little assurance. I historically ran Regular gas in my LX with great results even while towing. I recently found a very good source of 93 Premium as...

Note that I’m not saying premium will add a ton of power of mileage, just that the ECU does appear capable of tracking knock feedback and adjusting timing parameters to suit.
Gas mileage as it relates to gas has more to do with percentage of ethanol in gas. For any given tank you might have up to 10% ethanol. You could have way less. When we lived in AZ, the station I got gas at had ethanol in mix 6 to 7 months of year the other months no ethanol. I always got better mileage from all our vehicles on the none ethanol. Ethanol does not have a much energy as gas in comparable volume 30% less is given number.
As to additives most of that is mixed at distribution stations before ships to individual stations. However the bulk gas for most all stations comes from the same distribution point in given area. What can matter most is station age and holding tank age and filter system from tank to delivery at pump. Older tanks will have more water as they tend to allow for more condensation in the tanks. Also older tanks and pump will not have the better filter systems for removing water and particles. In the end GAS is GAS. Run anything that meets or exceeds the octane rating and do not run anything with more than 10% ethanol. You as consumer have next to no control beyond these points.

Higher octane number just mitigates pre-ignition, it does not clean anything.
Additives perform cleaning.
Use what the manual recommends, unless you have a tune or aftermarket *-charger.
Here is what my manual says (2021), note they do not use (R+M)/2 method (how most pumps measure Octane), but only R.
"Octane rating 87 (Research octane number 91) or higher"

You think that’s bad? Buy gas off a wagon in a rural area in Central America. Never know what you are going to get but if is from the red barrel you should be fine. Better than running out.
I’m imagining that to be featured on the top tier list there’s a cost to be associated with them and BP didn’t wanna play along.
OMG and yours hasn't blown up yet!!!!
200s around the world, like yours, are doing fine on cheap stuff....
I’m NA, yes it was fairly putrid comparatively to what is the norm given our proximity to world class refineries. I’m not comparing it to the third world or Asia where unattended liter bottles sit unattended in front of houses, etc.
Seconded. I’ll lob the grenade into the thread and state that running higher octane in my vehicle absolutely increases the ability of the engine to advance engine timing under load, which sometimes results in a noticeable difference in power. Or more specifically, it prevents a reduction in power which can occur with lower octane fuels under load at high ambient temperatures.Depending on what someone means by “take advantage”, testing shows that may not be the case.

Knock correction learning value when I run 91 octane is typically around +18. I’ve seen it cross 19 with 93. On 87 it sits around 14-15 and very occasionally will get up to 17. KCLV for the uninitiated is the amount of timing advance permitted by the ECU before it predicts engine knocking and has to retard the timing. So there’s no difference in power driving around town, but if I’m on the highway going 75, especially loads down towing, and it’s 95F in Nebraska with a little crosswind on 87 I consistently will find the truck has to downshift to maintain 65-70. If I consistently run premium this doesn’t happen.
All that said to the OP my rig is modified and I notice it more when towing (which means running in 5th gear for me). Your experience may vary. And except in the circumstance where I would have a drop in power in the above conditions and have to drop down to 4th gear on the highway to maintain speed there’s zero actual difference in MPG
With your screenname .... there is no. need for a thread around here
Just saying the Land Cruiser V8 will run on just about anything. Premium is definitely not required.
I just filled up with 91 at Costco his a.m. noticed the 87 was .75 cheaper, at about 2.50/gallon. Yikes.
OMG!
I paid $4.65 (and nine tenths) at Costco for the cheap stuff yesterday
