Petron XCS, Shell V-Power or Caltex Gold?

[emj21]

Shell V-Power gives me good experiences. But current supplies for Shell fuels is kinda so-so with so many stations without fuel to sell.

BTW Petron XCS is just like Shell Unleaded. If you want the high octane gasoline from Petron, its Blaze100.

sir gh....
pareho lang Xcs ng petron sa super unleaded ng shell?
hindi po ba super premium ang ka level ng Xcs sa Shell?
ramdam ko parang mas okay ang hatak ng Xcs sa car namin and less ang vibration compare sa sa super unleaded ng shell.. o baka naman placebo effect lang sakin?
