I will be getting my getz this afternoon I'm so very excited coz this is my first car. Please advise me which fuel should I use for my first full tank. Ang malalapit d2 na pagasulinahan is ung caltex and total mejo malayo na ung shell at petron... ok po ba gas sa total?
I suggest you use the octane written in the manual. Using a lower one will be bad while using a higher one WON'T have benefits other than more expense. As for brand, why don't you do trial and error for the next few fill-ups and check your FC and performance with each?
You should be ok with regular unleaded fuel, IMO, if the car does not specify premium fuels like Shell V-power/Petron blaze/Vortex Gold, don't fill up with these fuels because its just going to be a waste of money as you are not going to benefit from using premium fuels.
