Technically, Latio can safely accept 95 RON, but I felt my Latio was smoother running on 98 RON.Wonder if this is psychological or does 98 RON really make our Latio's engine smoother?
Definitely there a difference, but it difficult to measure.
Actually don't have to measure just a little maths. 98-85=3, even my kid knows that.
Your math fail is it?
