I have a similar post to a recently closed thread (you guys are ruthless ) except my case is probably the more typical rather than the exception.

I've noted in previous threads that it's not worthwhile to import my 2006 Sonata V6 to the Philippines. Things have also been said about its "thirst" for gas.

Well then, I want to know how much gas will I save if I decide to commute from say, Las Pinas (RFC Mall) to say, Manila City Hall instead of driving. Has anyone ever estimated how much gas is used on a round trip between those 2 places and compared it to the current jeepney/bus fares?

If my wife and I do go back to the Philippines, the very first thing I'd do to while away the time is finish my BSME course in Mapua. I'm contemplating if commuting or driving is more cost-effective. Time doesn't matter. I have all the time in the world.

Let's say the car I'll have there is a Mazda 3 1.6L 4-door or a Focus 1.8L Ghia.
