2011 Accent AT - Engine Knock!

[andretti]

edi meaning sa fuel nga talaga natin to if ganon?

added: *miekey and andretti saan ka nag kakarga nang fuel mo?

ako kase sa caltex lang and always gold lang.

I have been a regular shell unleaded user, pag wala naman its either XCS or caltex gold.
Up to now wala naman knocking sound yung akin (2500km + on my ODO)
