Why does the indoor air conditioner emit an engine oil smell?

[SophiaLynn]

Reasons for the indoor air conditioner emitting an engine oil smell: evaporator leakage, substandard gasoline. Evaporator leakage: It is more likely that the joint between the evaporator and the connecting pipe is not properly connected, leading to leakage. Refrigerant leakage does not pose significant safety issues since current refrigerants are non-flammable. However, after leakage, the machine's cooling and heating efficiency will be reduced. It is recommended to immediately contact after-sales service for inspection. Substandard gasoline: If the smell occurs in the external circulation, it is advised to replace the carbon canister. If it has been recently replaced, check whether the seal is not tight enough. The smell is caused by incomplete combustion of substandard gasoline. Gasoline leakage due to fuel tank damage.
