Premium Fuel Requirements Explained “Not Required”

That very well could be true, I have run Kroger gas in my BMW X5 and my Mercedes 280 and have never had an issue with it. To each their own.........
From what I can gather, European vehicles can be more susceptible to intake port and valve deposits than other makes. VW had grief in this regard. This is why I love the Toyota D-4S dual-injection system.
 
What really surprises me is all of these guys that bend over backwards to have ceramic coating, hand wash their cars, change the oil twice as often, do everything they can to treat it right and then complain about spending a little extra for a good premium detergent fuel.

I could be proven incorrect, but I believe the detergent level is the same for regular and premium fuel. However, no ceramic coating nor hand washing, but I do change the synthetic motor oil at 5K or 6 months, whichever occurs first.

Oil change at 5K for me as well!
 
I normally buy a couple cases at a time from amazon Toyota dealers for approx $100.00 per case.
Mobil 1, and OEM filters. I see Walmart now has Mobil 1 0W-8, which the normally-aspirated 4-banger now uses. Who would have thought oil would be that thin? The clearances must be ultra-tight.

Soon we’ll be using 0w-0, aka purified water
 
Regardless which gas you fill up your LC with, the gas tank is WAY TOO small!
This puzzle me, as noticed the specs on the LC in an international market, albeit most likely a diesel, but it was right at 30 gallons. Some might say the hybrid battery intrudes on space for the fuel tank, but to me it appears to actually intrude on what would normally be rear floor space.
 
But it still doesn't explain why the powertrain output (hp and torque) is the same for the Tacoma Hybrid and the Land Cruiser ...but the Land Cruiser "requires" premium but the Tacoma Hybrid does not (it's certified/rated on regular unleaded). There is still something funky about the setup—that they are different. I do agree with David...the Land Cruiser powertrain should be "safe" running on 87 but I still wonder what powertrain output (and fuel economy) is when running 87 vs. 91 (and 93) octane on the Tacoma Hybrid and the Land Cruiser.
What I was thinking as I listened to video.
 
I hope he is correct, but a query to Toyota re the 2024 Land Cruiser has responded that the warranty may be voided. Obviously, he is not driving a Land Cruiser, where directly on the fuel filler door it indicates premium fuel is a must. This said, with modern engine technology, there is no reason in my opinion the engine could not accommodate 87, or even 85 (which is what is typically sold here, such as at Costco) grade fuel, especially at our roughly 4000 ft. altitude. In Death Valley, possibly another story...
David does have a FE LC.
 
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. Before you add comments, please look up the pedigree of David, his engineering background and his direct contact to the Tahra Plant.



Waaaaht… ?. Great video.. .nonbiggie.. minor tradeofffs. Simple as that… .. only if it were.. in reality it is.. … .. fwiw… Using higher than req Oct.. is 0 gain.. all on board ya? Cool!, And why.. ,, all together … because the plug fires b4 the “higher” Oct flash pt (👋 few bucks). …



(Reelin it in, it’s late or early.. ) same engine, various models, prob same ECUs.

Slightly diff programming. …..

knock knock LC. ( wt?)… a Yota87 .. (a 87who.)…. Knock around n ask…. 🤯



Small drop in performance/ efficiency.. little ping, etc. Nothing the Knock sensor can’t handle. Better hope it throws a MIL… Maybe knock the operator sense..

Combustion detonation.. (synonym. ). There’s a tug o war in combustion chamber.. run rich.oil loves it.. .. catalytic too..

David previously worked as a vehicle evaluation engineer at General Motors headquarters in Detroit. He is also an experienced automotive process engineer (he was the first employee of CAMI GM/Suzuki joint venture plant) and was a former Management Consultant specializing in Supply Chain.

Process engineer and specializing in supply chain does not make anyone expert on piston engines just because they have a you tube channel.



David if you are reading this i live in same city as you and would love to share my 35 years of piston and jet engines overhaul knowledge and manufacturing process. Difference between 87 and 93 and we can also talk about 100/110 LL.



Follow manufacture recommendations not you tube or google mechanic

The first record of using a lubricant industrially is during the building of the pyramids. Some of the artwork/hieroglyphics show the Egyptians using water to help move the giant stones used to build the pyramids. Why do I know this stuff?

You have an A & P license? Worked as an aircraft maintenance engineer?
 
I just picked up our LCP yesterday and while the service tech was filling up our first tank he told me that it's very pick and to only fill it up with premium and that he recently had to drain the entire fuel tank of an LC because the owner put in 87 and it started knocking really bad..

They may have drained the fuel tank at the owner's request but the rest is BS. I have 10k on the ticker using 87 and it has NEVER knocked once.
