What do you want for Hyundai Yashi 15000Km three packs? how much is it?

Change the oil and oil grid, and then check whether the air conditioning filter and air filter are clean. If it is not clean, replace it together, and nothing else needs to be replaced. What engine cleaner will 4S let you add? You can add it if you have money. You don't have to add it if you don't want to. Anyway, 15000 km will not be dirty. They will also let you wash the throttle. I felt very wronged when I let them wash it once last time. I just washed a bottle of carburetor lotion, and the light working hours are 80. I won't let them wash it now anyway. I wash it myself, five yuan at a time.
