Only a Toyota engineer would know what the "rated" hp should be at the wheels as measured on a dyno (it's not what is used in marketing for "engine hp")
Fuel - Premium only?
- Thread starter ET2041
- Start date
I have about 5200 miles on mine and have tried regular, mid grade and premium. My mileage has not changed, but I rarely am over 3K on thae tach, so for those of you that do, I can't comment on that, My mileage has never varied from around 20 to 21 in mixed driving. I have currently gone to regular only.
I treat the owners manual as a minimal guideline (except for fluid change intervals) and will pump 93 or 94 if it’s available.
Ever since I crossed 5000km, my mileage seems to have improved big time and I have been consistently getting 9.3-9.5 L/100km or 24-25 mpg.

Tacoma puts posted torque and HP ratings at the wheel,
There is one dyno test where they found Tacoma puts hp&torque numbers close to what the engine is rated for at the wheels. So the engine probably has higher hp and torque at the crank compared to what is reported. This may mean Land Cruiser is actually even higher.
I run 87 octane most of the time . I honestly can’t tell a difference in running low octane versus premium.
Gas mileage still sucks .
11487 miles my average is 17.6
Notice those dyno tests are part time 4WD Tacomas which will likely put down more wheel hp than a full time Torsen differential Tacoma or LC250. Toyota probably picked a conservative crank hp rating to account for differences in drivetrain power losses.

17.6 is still better than my 2012 4runner Trail Edition at 16.4 mpg.
I routinely use 87 from Shell or Citgo
Mazda posts different numbers for their turbo straight six in the CX90. If you run premium, then you get 340 HP and 369 ft-lbs. But, 87 octane produces 280 HP and 329 ft-lbs. The ECM has to recognize that it can run more boost to get those numbers. If Toyota doesn't program the ECM to take advantage of the higher octane, then that's pretty disappointing.
Are you trying to Jumpstart the debate as to whether octane just eliminates knocks or also helps with power and fuel efficiency? Isn't this topic long enough 
Ummm. Maybe? Higher octane allows higher compression which leads to more HP and torque. That's not really the question. The question is whether or not we really need the higher octane in our fuel tank. The numbers from Toyota suggests that the higher octane isn't necessary. I use premium, but I wonder if I'm getting more HP and torque than people who use regular.Are you trying to Jumpstart the debate as to whether octane just eliminates knocks or also helps with power and fuel efficiency?

Maybe the admins can create a quarantined forum section for tire size w/out lift, best motor oil, and minimum octane threads?Are you trying to Jumpstart the debate as to whether octane just eliminates knocks or also helps with power and fuel efficiency? Isn't this topic long enough
Enter at your own risk.

Premium fuel required, or not?
So, will the 2024 LC operate successfully on regular (87) fuel, or not? The owners manual recommends premium, but does not seem to demand it. To be precise, from the owner's manual... "Select premium unleaded gasoline with an octane rating of 91 (Research Octane Number 96) or higher required...

Premium Fuel Requirements Explained “Not Required”
At 21:00 minutes into the video David does a very good job explaining. He did a good job and once and for all putting an end to all the mystery. Yes, if you want maximum performance you will need to put in 91. If you us 87 you will not get the performance, but it will not damage your engine...

Super Confused in Fuel needed for 2024 Land Cruiser.
Read where the gas opening says premium only yet I’ve also read this is preferred not required. Any definitive answer? Thanks

Premium Fuel or not?
I have seen mixed information. Is premium required or not? What is everybody running? Is there an advantage?

2024 Land Cruiser require Premium Fuel?
Not sure if this has been posted, but does the LC 2024 require premium gas only? With the now known much lower MPG it may very will take me out of the LC buyer and onto the 2025 4Runner gang.

Watch this for final word on which fuel to use (Hint: Premium fuel matters)
I've seen a lot of debate about premium vs. non-premium fuel. I suggest everyone watch this video. You can skip to the 17:07 mark. The whole video is good, but he specifically addresses premium fuel at the time mark I provide. I guess there are those who don't value this guy's opinion, but...

So it has been confirmed, 2024 Land Cruiser require's Premium Fuel.
Well that is just giving me gas!! I know the difference where I live is 6 cents per litre between the reg unleaded and premium....but you know, still. Shouldn't really make a difference if i purchase or not , but it is giving me second thoughts.

Premium vs Regular MPG: A 34-Tank Test
Like most of you, I've been curious about why the T24A-FTS is rated at the same horsepower when spec'd for Premium on the LC vs Regular for the Tacoma. Since I didn't have access to a dyno or a Tacoma I could run on Premium vs Regular and comparing that data to my LC, the most I could do was to...
