It's 1.0L. I got 5W-40 yesterday, but replaced it with Kixx 0W-20 today
. The fuel consumption has improved from 12 KM/L to 16 KM/L.
I see many people here complaining about hot weather conditions. I intend to contact Toyota Japan for their input on this. I'll also update on 0W-20's performance and anything that I can notice. Can you tell me what things to note to see how the engine oil is affecting the engine's performance? I'll keep a log book to notice any changes.
Thanks
