Absolutely agree. New car, especially sporty car, requires all oils changed after running in period completed, and after that at more closer intervals than what the constructor says if heavy duty road use, and after each track day especially in hot summer months.
you live in a country where synthetic motor oil is real synthetic P.A.O and ester base lubricant, here in Canada and the USA synthetic is group 3 oil, so it is just well-refined petroleum base oil, your lucky I wish I could have some of that here.
In my GR Yaris after changing from stock Toyota oil to Millers 0w20 EE Performance I noticed higher fuel consumption. About 0.5-0.8 l/100km. I consider switching to AMS oil. They have one oil which meets the specification. Regarding drivetrain oils. After 8kkm (and 3-4 track days)I changed all the oils. Rear diff and transfer case looked bad. Transmission oil looked like new. Good videos like always :)
Rear diff on these are pretty special, changed mine for factory Torsen LSD. Yep plan on changing my transfer and R diff fluids very 2nd service from now on (15,000kms) I engine service at 7500kms. Genuine Fluid and filters for me.
The rear diff also contains the all wheel drive "torque" split clutch pack. These clutches are constantly slipping! I did my change around 1000 km and the oil was very dark and contaminated. I think big portion of that is due to the clutch pack saying hello to each other. I also think this is a big reason why the next oil changes look so much better. Also keep in mind the diff and clutch pack swim in only 0.5 l, not much oil. I plan on doing the additional rear diff changes very time i change engine oil, its a very simple job. As for oils, Toyota calls for 4 different LT, LX, LF and SP (including engine) grades/package additives. The rear diff/clutch pack requires GL5 with limited slip additives. The transfer case does not require GL5/LS additive but is perfectly happy with it. Gear box is GL5, no LS additives because of the synchros. Finally engine needs to be low speed pre ignition approved.
This is wrong. The rear differential and the clutch pack have seals between them. The clutch pack fluid is sealed for life. The rear deferential fluid is contained within its own compartment
@@JFontes1969 according to Toyota the rear LSD needs the LX specification oil regardless of type of rear differential. There is a version of the manual floating about that calls for LT in the rear diff, evidence so far suggests that this was a typo as the up to date online versions all call for LX Finally I would highly recommend you look at aftermarket oils with the required additives as the LX fluid from Toyota is disgustingly overpriced. We are talking of factor of 5X compared to reputable brands with the equal specifications
@@JFontes1969 There is no front differential fluid as the front differential is part of the gearbox. Therefore you need to use the appropriate gearbox oil LT is officially for the transfer case. But because the oils come in 1L pack a lot of people just use LX for both of them as they both take combined total of around 1L
Thanks for all this content, great stuff! I’m just coming up to 600 miles 950 ish km so a timely catch of this video. It’ll be interesting to see the what comes out in the 1st and 2nd changes.
Hello, thank you for this information. The recommended oil change you describe on this video, are you specifically saying this only for GR Yaris featured? Tnx
I did my first engine oil change at 5000km and change it every 5000km. I did my first full drivetrain oil change at 20000km and will change them all every 20000km
You don't really mean to change the rear differential oil "as soon as possible" do you? I mean I could change it as soon as I drive it home from the dealer but why since it's brand new? Oh okay you explained it better later in the video. I change our engine oil every 5,000 miles and I'll likely do a drain and fill of the ATF every 25,000. We don't have a rear differential since our RAV4 is only FWD (front wheel drive).
@@RotheliRacing why? I want to ask you a question.... how has a piston ring changed in the last 40 years? Tolerances? All the same. So will a thin oil provide same oil film strength as thicker oil?
No advantage to using thinner oil other than fuel economy or tiny power increase. Nada. If you go too thick yes it may mess with flow rate /oil to some area but slightly thicker is negligible
@@Roboticpycotic i‘m no engineer. 🤷🏻♂️ A few months ago, i read a huge article about why Toyota uses this specific oil in this engine and it made a lot of sense to me. Plus i didn‘t heard of any problems from anyone ever with this oil specification in a GR, and neither did we, so i don‘t see any need to change it. You‘re free to use whatever you like, but i just recommend sticking to this oil specification.
@@RotheliRacing i work at dealer... what i see pisses me off beyond belief. They are literally going to suggest 16k oil change on an engine with higher cylinder pressure than anything they have developed? Engineers? NO!!! They take backseat to the marketing/bean counters every time!!

Thanks for creating all these videos , we learn so much about the GR thanks to you... Keep it up Philipee
Thank you Mate. ☺️

Hallo, may i know which AMS oil to use for GR yaris?
Rear diff on these are pretty special, changed mine for factory Torsen LSD.
Yep plan on changing my transfer and R diff fluids very 2nd service from now on (15,000kms)
I engine service at 7500kms.
Genuine Fluid and filters for me.
1145 km, went to service to get oil changed. Engine oil was as new, but rear diff was bad - black. Got recommended to change rear diff oil every 5kkm.
The rear diff also contains the all wheel drive "torque" split clutch pack. These clutches are constantly slipping! I did my change around 1000 km and the oil was very dark and contaminated. I think big portion of that is due to the clutch pack saying hello to each other. I also think this is a big reason why the next oil changes look so much better.

what does that mean? for the GR circuit/track version with torsen the differential oil rear is with LSD additive or not?

thank you for your informative answer, so with LX for the rear. But for the front we put the LT? however we also have the torsen at the front !

Amazing video phil, thank you! Where do you buy the Miller's engine oil? I'm lookinh into buying it for my soon to come GR Yaris as well
Hello, thank you for this information. The recommended oil change you describe on this video, are you specifically saying this only for GR Yaris featured? Tnx
Yes. That‘s specifically for the GR Yaris.
I did my first engine oil change at 5000km and change it every 5000km. I did my first full drivetrain oil change at 20000km and will change them all every 20000km
Another great video, thank you!
May i know the fuchs titan sintofluid sae 75w with 80 or 75w only? Thank you sir

Thanks for the video - assuming regular change interval for driveline oils is every 40tkm? doing every 10tkm with mine..
Depends if you track the car or not.
Another really good video 👍👍
Thanks Mate
Listen, I do not track my car, but I do drive fast and it is very hot where I live. I will go with 0w40. What do you think?
Just use the Oil Toyota recommends.
Thats what i think. 😁
Why don't you just use a thin 5w30????
Because i like to use what Toyota says you should use…
