Compressor oil

[incar]

I want know what kind oil for THERMO KING MDI COMPRESSOR it is possible to use. The original gas is R12 but now it is MO49PLUS (R437A). Thanks for reply

For MO49PLUS no change of oil is required as it is compatible with traditional lubricants.
Flush the sistem,replace the drier and charge.

Hi incar

you dont need to do anything....it is a drop in replacement...meaning take the old refrigerant out and just drop/charge the new refrigerant....just need to check/adjust superheat
