Hi mga tsikoteers, may alam ba kayong bilihan ng timer counter. Someone has told me that this is the best way for change oil schedule. This will count the number of hours na umaandar yung makina ng kotse natin. For Gasoline engine ideal is 250 hours and for deisel is 200 hours. This is more accurate compare to the millage that registered on our Odo where we base. He has a point because they are using this in Middle east on their change oil schedule. has anyone have tried this or installed this in here? Pa share naman kung saan nakabili. Salamat...
