Vios Engine Knock 2013 1.3

Mga sir pagnagpalit kayo to other gas intayin nyo makailang palit. Pag gas muna kayo 300 pag near empty na then ubusin nyo ulit then same procedure ulit bago kayo magfull tank. Ive been fillinup up petron xtragasoline then nun nagkaron ng engine knock tuwing cruising nagpalit ako ng blaze then nun nawala balik ulit xtragas. Lipat na rin ako gas station. So far wala na knock khit xtragas lang

AFIAK, 93RON ang required sa Vios. 91 is too low. Baka you are looking at US Spec RON where 91RON US =95RON.

Kinda weird that our gas stations are still selling 91RON. Its just too low. Just load up with 95RON to avoid engine knock .

WTF?! That picture I posted was from my Vios' manual. The very same Vios that has been running on 91 octane since I got it, and still able to do over 190 kph on the highway with never an instance of knocking.

It's not weird that our stations are selling 91 RON, because majority of cars sold locally require 91 RON only. Unless it's stated in your manual that the car requires 95 RON, you don't need 95 RON.
