Hi all, 08 Vios S spec reported in
Any sifu(s) can enlighten me? Previous time, been using Chemlube full syn 10w/30 all the way. This few services change to Torco SR1. Used 5w/30 for the 1st time and problem came on 2nd time, TER-used 5w/40 . Just wonder can use back 5w/30 cos few of my friends mentioned "old" car better use 5w/40 instead of 5w/30 due to better protection (more thick). But i miss the 5w/30 pedal feel. light light Please advise.
