A/C Refrigerant Oil Replacement

WARNING: This page does not describe the selected car, but rather 6 other vehicles, including the 2014 Honda Ridgeline, 2013 Honda Ridgeline, 2012 Honda Ridgeline, 2011 Honda Ridgeline, and 2010 Honda Ridgeline. However, it is still accessible from the selected car via links, so may be relevant.

Recommended PAG oil: DENSO ND-OIL 8

P/N 38897-PR7-A01AH: 120 mL (4 fl.oz)
It is important to have the correct amount of refrigerant oil in the A/C system to ensure proper lubrication of the compressor. Too little oil damages the compressor; too much oil reduces the cooling capacity of the system, and can produce high vent temperatures.
To avoid contamination, do not return the oil to the container once dispensed, and never mix it with other refrigerant oils.
Immediately after using the oil, reinstall the cap on the container, and seal it to avoid moisture absorption.
Do not spill the refrigerant oil on the vehicle; it may damage the paint; if it gets on the paint, wash it off immediately.

Add the recommended refrigerant oil in the amount listed if you replace any of the following parts:

A/C condenser.........45mL(1 1/2 fl.oz)

Evaporator...............45mL(1 1/2 fl.oz)

Line or hose.............10 mL (1/3 fl.oz)

Leakage repair.........25 mL (5/6 fl.oz)

A/C compressor.......For A/C compressor replacement, subtract the volume of oil drained from the removed A/C compressor from 125 mL (4 2/9 fl.oz), and drain the calculated volume of oil from the new A/C compressor: 125 mL (4 2/9 fl.oz) - Volume of removed A/C compressor = Volume to drain from new A/C compressor.

NOTE: Even if no oil is drained from the removed A/C compressor, don't drain more than 50 mL (1 2/3 fl.oz) from the new A/C compressor.
