Q: Can I use polyolester (POE) compressor oil in my A/C system that requires polyalkylene glycol (PAG) oil?
A: No, the moisture count is too low in POE compressor oil and will not properly protect A/C systems that requires PAG oil.
Q: Do I need to change my A/C compressor oil?
A: No, compressor oil will only need to be serviced if it is contaminated or the fluid has leaked out.
Q: Do I need to flush my A/C system when I change my compressor oil?
A: No, it is only necessary to flush out the system if the system is contaminated. Then the system will need to be flushed before it is refilled with refrigerant and oil.
Q: Do I need special tools to change my compressor oil?
A: Yes, in almost all cases, the ACDelco Oil Injector Kit J45037 will be required for newer vehicles or when you don't want to lose refrigerant.
