engine oil

[mrfudgeu]

2015 yaris 1.3 sedan 4automatic asian...

now its at 210.000 km...



since i got it(new ZEROs)

& i change it with 10w40 as recommended by the dealership

up till it reached 210k/km

the dealer was out of stack(to buy & DIY...)

so was wandering what type of oil my engine use since i forgot

cuz i usually go there & ask for yaris oil 10k... the blue bottle...

so i opened the book if the car

found that it says that its recommended for 5w30 .. but 10w30 Ok on heated area's...

so i asked toyota dealership mechanic...

& some response by "idk" or "10w40 & no WHYs"...



& some big DIY mechanic's like scotty from youtube .. says to stick by the book



so im wandering what U pour for your yaris...? whats best
