My friend once told me...

He uses the cheapest unleaded fuel from Shell.

Pero twice a year, when he goes out of town, he fills it up with V-Power (full tank) tapos regular fuel na ulit once maubos yung V-Power.

IMO, "Injector Cleaners" are the cheapest thing na pwede mo ilagay sa car mo to clean the injectors.

With modern fuels, it is not required.

Pero wala naman sigurong mawawala kung minsan minsan lang.
