Engine longevity

[dougmaz]

For sure. With a turbo engine, I personally would not exceed 5K/6 months oil changes. Actually, 5K with any engine for me...

I just brought my '25 LC in for its first scheduled service (5K miles) at the dealer and they told me that they don't change the oil until the 10K mile service, which I found crazy. I am going to change it myself.

The Fumoto valve makes it so much easier!!! And faster!!!

Battery will outlast the engine. That is why engine has 5 year warranty while battery has 10 year.

I wish that were true however all currently available battery data and engineering information does not support that claim.
I am not allowed to share the information i have access to. The value proposition is still a good one. The hybrid program is a good one and shall continue to improve over time. It will be very interesting as an energy systems engineer to see how this unwinds over time.

I wonder if driving for many years on 34" or 35" tires would diminish the engine longevity by added strain?

Engine longevity is relative. Some thinks 200K is good enough. Some think 300K is non-starter. What is your definition of longevity?

I don’t expect this engine to outlive the one from J200, or even the previous gen 4-Runner. But I do think 300K should be a no -starter, and 400K+ in average. They are put on a Land Cruiser so better live up to its reputation..

I would love to see these kinds of numbers, i won't, will probably play with other toys along the way.
200k miles on a turbo 4 cyl at a base weight of 5500 lbs would be impressive alone. Very impressive.
I sure hope you are right.
Time will tell all.

There are 1st gen Prius’s on the road with +200k miles still with original batteries…

No need to act like this is some cutting edge untested tech. It’s been around for close to 25 years now.

If this engine only pass the 200K mark and die, it will damage Toyota’s most iconic LC trademark so bad that it can barely recover. Even crappy American cars can pass this mark with reasonable maintenance.

And the batteries don't last forever, but they're also not expensive batteries. You can refresh a Prius for a grand or less all-in.

It's also fairly irrelevant to discuss the 4cyl surviving in a 2.5 ton vehicle, because the engine itself doesn't often take that load by itself. The engine likes to keep lower RPMs, where its peak torque is. It's not like these things are constantly in the higher ranges straining to move the truck.

The technical data and specs of the T24A are impressive. I know turbos are scary to the Toyota crowd, but they clearly learned a lot with their partnership with BMW. The T24A should be expected to be as reliable as the B48 (which has zero outstanding common issues btw) but with added redundancy and reduced complexity. It's a brilliant design. The turbo is cooled frankly more than it needs to be, and the engine itself is appropriately reinforced.

Tangentially related data point: https://www.autotrader.com.au/for-sale/toyota/hilux/4-cylinder?sortBy=odometer&orderBy=desc

there are i4 hiluxes (hiluxs? hiluses?) with 500K+kms (300K+ miles). Doesn't look to be turbo. . . and of course without hybrid. . . and hilux is likely lighter than LC250. . . oh, it is also diesel but some historic data is better than no historic data. FWIW likely these trucks spent good chunk of these miles on washboard roads under scorching sun in Australian deserts.

or even a better match prev gen prado, there is also a bunch with ~500K kms on them: https://www.autotrader.com.au/for-s...prado/4-cylinder?sortBy=odometer&orderBy=desc

I hope all the high expectations are met.
It is certainly an interesting experiment in real world end user data.
As i say, time will tell.

There is a guy who works as a medical courier who has driven 50K miles in just five months. I follow along and check back in each month.

Toyota’s nimh battery tech is rock solid, the main thing that kills them is heat and non use/sitting, high mileage is healthier for the battery than letting it sit for long periods.

Keep the battery cooling vents clear and make sure you drive the car regularly and the battery should last 15 or more years.

Also it’s a good practice to turn on the AC in a Toyota hybrid if you feel hot vs opening the windows since the batteries rely on cabin air to cool down.

How often do you mean by regularly? Is roughly once a week with occasional long multi day road trips(2 to 3 times per year) thrown in enough?

 

[Area 51]

To be clear, this is all anecdotal data and information. The Cruiser use case is new and unique.
Time and mileage will tell the tale as things unwind over the next few years.
Charge discharge cycles, heat aging, infant mortality rates, on and on. To try and guesstimate and influence buying decisions based on historical pretty much non applicable claims and data is futile at best.
Warm fuzzeee stuff ok, time will tell young Skywalkers.

I suspect that the few people who baby their engines (keeping RPMs relatively low and changing the oil often, etc.) will see high mileage. The weight and aerodynamics must have some negative affect which is why I think babying the engine is key.

The batteries will degrade over time and need repair/replacement. I look at that as a normal part of owning a hybrid. My understanding is that other Toyota hybrids will continue to drive with degraded (not dead) batteries for a long time.

What's high mileage? We're all just guessing. My guess is that 200-300k won't be uncommon and over 400k will be less common. There will be some oddball who gets a crazy high number and some poor folks who only get 100k.

If you’re spooling up the turbo a lot, you’re really missing the point as to how Toyota designed this drivetrain to deliver power. At low rpm’s, the engine (w/o the boost of the turbo) and electric motor combine to yield close to 400 ft lbs.

Driving it like it’s intended to be driven is not necessarily “babying” the engine. I think it’s better described as better matching one’s use with the design of the tool.

They said the same to me. Mine was almost at 2500 miles but I’d had it for about six months. I told the guy I want the oil changed. They did. I don’t care what they are going to say. If I’m paying for an oil change, I should be able to bring it in weekly for one.

 

[markofky]

I’m curious. How well do we (LC owners) expect the 4 cyl turbo hybrid engine to last? Part of me says that the vehicle’s weight is going to reduce the lifespan. BUT, I admit I’ve never owned a turbo, hybrid, or a combination of both. I’d love to hear from experienced Toyota owners. Cheers.

Being my 12th Toyota in 42 years and still seeing older ones I sold years ago, I have no doubt my LC will outlast me. I’ll never know but would expect hundreds of thousands of miles with regular preventive maintenance. All of mine go to the dealer every 5k and that represents a lot of value to anyone considering buying when I decide to sell

I don't want to sound mean so please don't take what I write as mean spirited. It doesn't seem like you know what you're talking about

In terms of the battery/hybrids system Hino has been using a similar hybrid system in their trucks for years. There's nothing new in terms of battery chemistry or a parallel hybrid system.

Toyota has also been using turbo 4's for decades (not in the NA market) and they've proven reliable.
