An interesting video...

And at the same time, hybrids reach the mileages of 400k miles and more without issues 🙂 So they have to be built from the titanium I guess? 😄 Or maybe, just maybe, the engineers took that into their calculations and that's why they recommend 0W8 (which some of my fellow countryman describe as the water after boiling sausages ) 😉

Indeed they do...

I just thought that the technicalities and details were interesting... (even though it is a sponsored video)

Well that was a blast from the past. 8-10 years ago I had an American V8 and his channel was on my subscription list.

But I take some issue with the water problem - 100°C is not a magic bullet. Water evaporates at lower temperatures too - not many washing lines (or tumble driers) run at that high a temp but the water still gets away. (Fun fact - washing put outside when it's sub-zero and thus freezes will still dry (if it doesn't rain/snow) though it may take a while. The water actually sublimes from it, going directly from ice to vapour.)

Heat just speeds up the process and I'm not sure the difference between 70-80 and 90-100 is really a huge problem. Of course never getting to those temps due to very short journeys is a problem for all ICEs.

It's one of the reasons I started hooning mine around - It made my diesels noticeably happier compared to when they were only pottering through London's hell roads, and even the hybrid, which everyone assumes runs better on urban roads, seems much happier when I let it stretch its legs a bit, so to speak, now and then.

Interesting indeed, thanks for sharing. 
In fact there is nothing new here or strange and we all know about the mayo that happens to all engines when car not used long enough to make water evaporated. All these things been examined, tested and all adjusted and taken care by the Toyota engineering team. All we need to do as owners is just maintain on time and drive sensibly. That’s it.

Hmm, well it’s clearly an advert for his sponsor and I’m all for far more frequent oil changes than 10k but his examples are extreme and if I refer to the huge taxi hybrid population in Manchester that get zero special treatment, most are over 100k, many are over 150k and a few are over 200k and when they eventually get booted off, it’s the car that’s cream crackered, not the powertrain.  He’s not talking rubbish but by heck, he’s labouring the point.

I think that the point about frequent starts that he covered, but didn't labour in deference to his sponsors, is that they aren't cold starts or starts with long stopped intervals. A warm, oiled engine doesn't really have a lubrication problem. 

That said ... Will the MK4 Yaris with the greater EV capability have a problem with the ICE being stopped for longer periods? Curious minds want to know.

[Cyker]

I think that's one of the genius decision Toyota made with the Mk4 - At first I was very confused by why the traction Battery is so tiny - It's literally half the capacity of the one in the Mk3, but I think someone there had a zen moment: As we always point out to new people, hybrids are not EVs, they aren't designed to run on the Battery alone, so you don't actually need a big Battery, just one 'big enough'.

By halving the size of the battery and making it lithium, it's shed a load of weight - I think, despite the increase in structural bulk in the car for safety reasons, it's still comes out lighter than the Mk3?

That alone helps with mpg, but also because it's smaller and can't run MG2 for as long, the engine has to cycle on and off a lot more. It's made the EV mode button completely useless, but the engine doesn't have the opportunity to cool down as much which keeps it in optimal operating temperature more often.

The Mk4 could do with a radiator shutter or something though, as in winter, the tiny mass of the engine means it does lose heat very quickly when in slow traffic which, combined with the HVAC sucking heat out for the cabin, really hurts the mpg as the engine struggles to stay at its operating temp when struck in a long queue for ages.

The guy in the video is no fool but I used work for a friction material manufacturer and the aftermarket guys are always trawling for snippets of information to do the competition down.  The info he’s using has come from Mobil’s marketing department - it’s written all over it.  It comes across like they’re one up on Toyota but Toyota don’t guess at such things, they’ll consider aspects that lots of us don’t even think about.  These Dynamic Force engines are so well made with such fine tolerances that the oil more or less stays where it is when the engine stops and if you force oil through fine gaps it speeds up so fast it’s up to pressure again virtually instantly within the parameters of temperature they control by starting the engine if needed.  Poor old Colin will be thinking we don’t appreciate his YouTube offering!!!

Per Oscar Wilde (allegedly) "There is only one thing in life worse than being talked about, and that is not being talked about." (In modern parlance it'll be clicks/likes/views, or lack thereof.)

And he (Colin) did acknowledge it was sponsored.

Good point. Capillary action hadn't occurred to me.

[Cyker]

Also good oil should cling to metal surfaces for a fairly long time; All that guff about how Castrol magnatec sticks to metal actually applies to all decent oils, although that's more surface tension rather than any magnetic quality  

One way to really know when oil really needs changing rather than the colour is when it can no longer retain a properly slippery and substantial layer of oil film on a metal surface, although it can be harder to tell with some of the thinner oils!

Nah... I'm made of sterner stuff... 😉

Could his hypothesis also be linked to those silly stop/start systems? Similar scenario.

Actually the hybrids has absolutely no issues with oil , these are all customers oriented talks and advertising.
The Toyota hybrids engines aren’t any harder on anything. They are the best from all types internal combustion engines.  The stop start technology is stupid and those hybrids with dedicated starter like Mercedes’, bmw , Audi hybrids. These perhaps might be hard on oil and anyone else. Except Toyota hybrids where they are simplified engines all others are in fact over complicated, over engineered and not reliable, neither more efficient then purely petrol or diesel equivalents. You want a hybrid, buy a Toyota. 

[Maurice Mynah]

I possibly worded my post incorrectly? I'll try again - it does seem strange he only refers to the engine stopping and starting with a Hybrid system and an alleged issue with oil circulation, or lack of. He should also have referred to the (stupid) stop start system fitted to many non Hybrid vehicles - same sort of thing - engine stops to save the Planet, engine starts.

I believe Toyota did the sensible thing and now don't use stop/start?

The video author is American. I'm not sure they have stop/start over there.

True, and it’s taking a bit the pleasure of smooth driving experience, but easily turned off by a button. I believe the stop start might be mandatory similar to all other stupidity like tpms and more. 

[Cyker]

I will say the Toyota stop-start system, when it works, is quite good and very unobtrusive, esp compared to some other manufacturers ones - Some of them have a nasty delay when they restart, but the Toyota ones I've experienced have been smooth and nearly seamless and made me wonder why starting the car normally isn't as smooth or immediate! (I'm not talking about the hybrids though - Those are on a totally different level!)

A lot of people were saying stop-start would create a load of unreliability but surprisingly it doesn't seem to have done much; Once the engine's warmed up and has circulated oil around it doesn't significantly increase the wear, and the starter motors seem to have been more reliable than normal starter motors in most cases.

I do think the stop-start systems are a bit pointless as their benefits are quite dubious, and they generally don't stay off long enough to make any significant reduction to emissions once the system's got a few years under its belt.

[anchorman]

I think if a car is Type Approved with stop/start you shouldn’t be able to disable it.  If you need it to meet emissions standards, it should be used all the time.  All our hybrids do it and I had several Mazda CX-5s that all worked perfectly.  I used to love the way it used to set the climate back to a very low state in traffic and sit there in virtual silence.  If you were to plug your ears, you wouldn’t know it was stopped, the start up was so seamless.

What's if it's there just for the WLTP result and not the Euro emission standards? 🙂

So as he states where i have started the video below if you live on a small island where the engine rarely gets up to temperature you may have issues the rest of us who drive fairly often, fairly far or leave our cars in ready mode to charge the Battery are not going to have oil related issues as our engines will reach working temperature often enough to get rid of the moisture, move along nothing to see here  😉

EE was a good channel but it has gotten a lot more click-baity over the years, with fewer 'normal' videos and an increase in sponsored vids... ChrisFix also has reduced output a but at least his videos are still objectively informative. I'm worried EE is going the way of Scotty Kilmer...

A lot of channels do this. Google's advertising algorithms and other Ts & Cs  get updated quite often and it's not uncommon for a channel to suddenly have reduced or no income for a time (until they can adapt - if they can). Sponsoring, and Patreon or other subscriptions, is a way to buffer against that uncertainty.

And of course some channels eventually just burn through everything worth saying about a subject and have to get 'ideas' from other sources. That's especially true of ones that have a regular date for uploading a video - typically weekly. Tom Scott pretty much did that, but at least he admitted and accepted it - sort of - and basically shut the channel down for new content.
