You are using a really good oil in the correct spec 0w20 API SP for your engine. Your changing intervals are also pretty good 👍

Me too mate! It is about 1 in 100 among the cars we are monitoring now, so fingers crossed! 🤞

Milages 70000km. 0w-20 Engine Oil and only RON 97 fuel. Stock standard and no modification at all. So far no complaining and running absolutely good.

Suit yourself mate, but the people involved go all the way to Toyota and I’m walking on thin ice here…

Yes mate, you nailed the point exactly: they can’t make this kind of product and then not stand behind it. They are missing out, because people could decide to turn elsewhere…

Yes, everyone that has opened these engines to forge them have seen this

Yes I agree, I said this also in the video, they are not honoring warranty claims or recalling because this would be super expensive for them! But, cases are increasing and if they reach the number, they will have to recall. Imagine those poor people that saw their cars burning down!

In reality, I have seen no downsides in using this weight of oil mate, just go with it. While it isn’t s guarantee, it helps preventing the issue. Cheers for your support!

The main and rod bearing clearances will be set to run 0w-20, running 5w-30 for the life of the engine will possibly shorten the life of the bearings. Is it worth the benefits of decreased cylinder bore wear? I think so.

@@vipercrazy9910I strongly disagree, sorry

They don’t shatterbm for pressure, they shutter due to the consequences of mega blowby!

Most cars are running well, but about 1% is having this issue, already now thst the cars are only 3 years old!

By the sound of it it’s a lottery.

@@GRfourfunyes, but older engines get, this possibility increases

My pleasure!

@@BushNG-cq1hm I’m using the same oil, but still 0W-20.

Please stop mis leading my subscribers: if you don’t like the channel, there are many more to explore. OW20 doesn’t protect the engine against the issue described!

@@AJClubsport I never said or suggested that 0W-20 protects the engine from this failure. I’m simply stating which oil I’m still using. Part of it has to do with warranty.

@VidNibs 5W30 is now accepted by dealers

Many stock cars are failing…

@@AJClubsport how many 100% stock cars exactly do we know of that failed from this issue?

@@VidNibsid like to know this also, as bad as this appears it could be <1% and highly unlikely to happen. More information needed

Thankyou, please share everywhere, and ask people with failures tonreport back to me

Yes, the 5W30 has a much more protective oil film than 0W, that is mostly used for consumption and emissions nowadays

@@AJClubsport I searched on Toyota's Microcat the original part number for the piston of the Yaris Gen1, Yaris Gen2 and Gr Corolla: on the GR Corolla untill september 2024 it's 13101-18040 GR Yaris Gen1 is 13101-18030 GR Yaris Gen2 is 13101-18040 and for the GR Corolla from september 2024 it is 13101-18050 The latest GR Corolla has not the same pistons as the GR Yaris Gen2 !!! So I wonder if they actually fixed the problem on the GR Yaris Gen2 ? And for all these different pistons they use the same piston rings ! 13011-18040

Hi, “reinforced pistons” - does it mean they took the same pistons from GR Corolla? If yes, then the issue can still occur.

@@bemisz3948 Seems like they did

@@erwinpaumen132 maybe they will change the pistons for GRYG2 from September(+) for the same as GR Corolla has? 🙏

This is great to know!

Hoping you won't have channels bullying to remove, like when Tundra videos started a few months before the recall. Steadfast

@@ryandoyle4344Thankyou mate, you understand, I had one today and another few go close… My information is very accurate, that is why I can’t tell who it comes from, this is a big issue now

No, many blow on the streets too

Cheers mate! I’ve been informing people about the oil for over a year, and you can’t imagine how much hussle from haters I got!

Not really, unfortunately, because the issue occurs with different heat conditions

Agree, I'm sticking with the oil they they recommend, Toyota should at least have a kit made available free of charge headgasket, head bolts and all seals etc + new piston ring set be made available for those who want to do this themselves or they re-call .

Best thing you can all do is to share your history and failures, I will collect and then we can move as class action

In 2013, Ford says 5w30 for v8, but 5w50 for v8 PP (performance package). Same engine, but more protection; now 0w8 b/c fuel mileage, but also less protection

Totally agree!

Probably because it's not happening enough to warrant a large-scale recall that requires basically the entire engine to be pulled and taken apart completely.

Yes, this is the point, bit numbers are increasing now…

It’s economics. Toyota will be very well aware of this issue. Loose rings seems to be a general design feature across Toyota’s current engine range, to save fuel by reducing friction but it’s now causing other (albeit less catastrophic) issues. They will try to avoid the (extremely costly) GR1 recall by all possible means for as long as possible. This means denying there’s a problem and rejecting warranty claims for any possible reason and quietly doing the odd “goodwill” repair. Let’s hope they do the right thing without delay and preserve their high reputation.

Thankyou Russ! It still isn’t clear what pistons they have really put in the Gen2: if they are the Corolla pistons, it isn’t fixed…

@@AJClubsportis there any way to checki it? E.g. verifying parts number - but I guess a casual user/driver doesn’t have access to it 😎

Not really a big factor in this lottery, as long as things are kept sensible

Yes mate, forging is the only way to have complete piece of mind. For sure they are gapping the rings for a reason, maybe the specific material they use expands more than what we usually see, and this dimension shift makes the issue happen

@@AJClubsport I suppose more time will tell if this is a build issue on certain cars or something fundamentally flawed on all of them?

@@STIStuff​​⁠at the moment its with all with them, then some have a more fortunate life of others…

@@AJClubsporthelp me make sense of this, if the ring material expands more than it should that means the ring gap is not big enough so the circumference of the ring would be greater? Surely that would be a tighter tolerance in the bore and be better for not allowing blow by? Or are you saying the ring expands too much and causes scoring leading to blow by?

Not sure it is a mistake, I think that is how they engineered it and it isn’t working ad intended. Not any mechanic, somebody that specialises in these engines

Well, there aren't many specialists for this engine, and it's not always easy to find one nearby😢

@@jorgeluismedinabegazo1043there is at least one in every country

Ant major brand, full synthetic, 5W30 API SP rated will be fine mate!

​@@AJClubsportWhy not OEM Toyota 0w20?

@@STIStuff Don’t use 5w30 or other grades of oil, Use only 0w20 API SP real full Synthetic oil ( Like Ravenol DFE 0w20) This engine is designed for the 0w20 viscosity and nothing else!! It states on the oil cap for a good reason !!All this engine failures and blown up motors like in this video are from wrong oil viscosity , no API SP specific oils and wrong software tunes and nothing else!!

@@STIStuff any oil that’s API ILSAC GF-6. Critical it’s GF-6. Oil change intervals at 3000 miles and please, please do not go with higher viscosity. Stick with the 0W20

Happy to help and share this information: please share the video with everyone!

Well said mate!

Wouldn't the ring gap also cause excessive positive crankcase pressure to vent oil back into the intake?

@ryandoyle4344 no mate, the PCV takes care of that!

LSPI , against this, the car needs the API SP Oil Generation. It's no big difference between the 0W20 Oil and the 5W30 Oil. Important is a big oilcooler for taking care of the engine with an oil temperature between 85 and a max.100 of degrees. The hotter the oil, the bigger the risk for LSPI. Important is also a very clean Max. 3000 km and then change. In Japan, they change the Oil before the track and after the track. And shure a good catch can system helps to filter the oil and the gasoline in the oil out of the system. Yeah, and another LSPI Problem with Pre Ignition is the Gasoline. 102-105 oktane gives Safety. And never forget, this is a street car, not a race car, same a 2JZ Engine.

@@holgerstoll4682​​⁠Thankyou, I agree with your statement, but 5W30 will always provide a better protection film with no downside

My question also….?

Yes, this is exactly the point: we still don’t know if the issue is fixed on the Gen2 or not, till we manage to get eyes on the pistons and understand what they actually used. Toyota is very aware of the problem and are trying to keep on top while trying to stay away from a huge recall on Gen1’s and Corolla’s

I’m not sure of your question, but my map peaks at 1.8bar and tapers to 1.3

1.8 bar on torque and taper 1.3 on max hp for the turbo speed ?

@TheSol115 350hp

Hello, yes on some rims the arms have a minimum interference at full lock. Not a big deal if you know. Best practice is always to check upon installation so you know if there is interference

@@AJClubsport do you know some rims that are not touching? :) would be a good data-point for the next rim set.

@@dvim​​⁠best thing is to reach out to Wiborg for this mate!

Almost as much as with the EZ cams on EcuTek, yes… Syvecs gives you much more flexibility and control in tuning, but at a huge cost

Very welcome mate, glad to support the community! Please share and subscribe to support me!

Don't you think the car is quick enough as it is? I suppose if you are racing it more power would be good but the standard car has more than enough for fast road use.

Hello, Basically same mods: intercooler, airbox, 70mm exhaust decat

Stock Turbo and “A” cams: this shows exactly the difference with the EZ cams, that nobody should buy

@@AJClubsport I guess Im going to have to return mine... glad I have not opened them yet :O

Without an ECU tune the engine won’t work mate! Thankyou for your support

Glad to bring you this information, it cost me a lot of money and time!

Engine Hp, where these cars make 260hp stock

Thankyou Lambros, this really supports me in this venture, and I’m going to do better in the near future! We will see about those two mods, still no confirmation

This is true, but OEM’s usually have at least 1.5x safety factor on sports engines. Next week a video explaining the failings is due

@@albertocarvalho8091 yeah well the engineer also designed the engine bay to be extremely difficult to swap turbos off of the motor set in addition to all the play in the motor from factory but you see us fixing the engineering mistakes. NVH or not.

I just moved the turbo and made one 800hp going strong still so I like this platform to tune on. Ash SRD Tuning

​@@ashleighcurtishahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahaha

@@albertocarvalho8091 go to my youtube bro.... SRD Tuning. It's also been on officially gassed and fastest GR Yaris in UK/Europe and it does track days almost every weekend.

Yes, that is the beauty of tuning, everyone can make their informed choices based on objective information like this we shared!

Yes, not everthing shoes up on the graphs, but the EZ cams I got are quite pointless unfortunately: its either a good tune on stock or A cams from my point of view. Driving the car, you don’t really fell anything missing down low, but much more in the high rpm range!
