why does the manufacturer confuses us by pasting a yellow sticker under bonnet of 10w40 and in manual it says 0w20.
0w20 looks like would be better if you use it in alaska if temprature is the main selection factor.
the manual is regulated by PTA so there is no chance it didnt go thru anyone else mind and they just kept distributing UK celerio manual lol
10W40 sounds too thick, i used to use it in my 7th gen civic 140k driven.
