A6 compressor oil
Thanks





ESTER Refrigerant Oil with ICE 32.
The label states can use when switching from R12 to R134a
Compatible with all A/C system materials
Compatible with all existing refrigerant oils.....etc.,etc.
The item I purchase was Medium Viscosity.
System is charged and works well, in the garage the other day,(about 90 degrees did a check on air temp,(Max & high speed) and I got 58 degrees at the vents, not bad and that was with no air movement through the front of the car except the engine fan. Of course I would like it colder....
Measure the amount removed ndre[lace with exactly the same amount.

You can probably find the complete paper yourself.
You will find the products and info on r12 mobile systems are getting harder to find as the years go by. It's been almost 20 years since oem converted.

The only refrigerant lubricants approved by ACDelco are:
R-12 Systems
• Mineral oil – ACDelco P/N 15-117 (GM P/N 12301108) - 525 viscosity universal oil
for all Harrison/Delphi manufactured compressors.
• Mineral oil – ACDelco P/N 15-116 (GM P/N 12323913) - 300 viscosity for non-
Harrison/Delphi manufactured compressors.
R-134a Systems
PAG lubricant – ACDelco P/N 15-118 (GM P/N 12356151) – 600 SAE or 150 ISO
viscosity for all R4 and A6 compressors. For all other ACDelco supplied service
replacement compressors, use the 46 ISO viscosity universal PAG oil, ACDelco Part
Number 10-5040 (GM #89022191) in the 8 oz. bottle or Part Number 10-5026
(GM#88901445) in the 8 oz. cartridges. A/C oil injector #J45037 should be used with
the 10-5026 cartridges.
There are no Ester lubricants approved by ACDelco for retrofitting R-12 systems or for
use in R134a systems.
Use of the correct refrigerant lubricant and amount is necessary for proper air
conditioning compressor operation and durability. Incorrect lubricant will damage the
air conditioning system and its components will not be covered by the ACDelco
warranty.
For vehicle applications with non-Harrison/Delphi manufactured compressors, follow the
vehicle manufacturers’ specifications for the correct viscosity of PAG oil.
