Chief kung hindi na cover ng warranty advie gls sport mo pwede na sa labas ng casa yan!

you can go to your nearest "reputable" gas station (like petron and caltex). Not only that labor is cheap for oil change and tune ups, pwede ka mgdala ng oil of your choice sa kanila, unlike shell wherein there is extra charge if you're not going to purchase their oil! Although shell gas stations has more likely casa-type service (Helix Service Center), may package din naman yung ibang mga gas stations and they are also equipped to provide good pms (depende sa branch!--makati area, quezon ave area...) similar to what casas do.
