Fill Petronas for my UDM most of the time unless can't find one during a journey, why make the ang moh's rich. Political filling ekekkekeke :lol:
Personally, I find:
Projet = smooth, perfomance average, FC slightly better
Petronas = smooth, perfomance average, FC average
Esso/Mobil = smooth, perfomance average, FC average
Shell V-power(vapourising power, hehehe) = Excellent but costly, smooth, power to certain vehicles. No difference in my UDM but previous car FIAT UNO can feel the difference. Vapourises fast that's why make us think our FC is high. :nyehehe:
