Valid data shows that
A bottle of good refrigerant can be used for years. A bottle of bad refrigerant will stop cooling in two years. Eighty percent of the original refrigerant for cars! ! !
All replacement:
》Mini car: Bottle (single air conditioner/double steam air conditioner)
》Mid-level sedan: Bottle
