Unfortunately, substandard gas is commonly used, especially at unauthorized workshops:

Many workshops use cheap o r contaminated refrigerant even butane mixed with R134a, which damages the compressor.

Overcharging o r undercharging gas leads to inefficient cooling and long-term damage.

Always insist on R-134a for most Changan models and certified gas refilling from a reputed center.
