Are all PAG oils compatible?
The universal oils don’t list a viscosity because they are compatible with all of them, sort of like a multi-vis engine oil. They were developed so that shops wouldn’t have to stock so many different vis of pag, ester, and mineral oils. You could probably use the universal oil just fine.
Is all PAG oil synthetic?
PAG is actually an acronym for Polyalkylene Glycol, and it is a synthetic oil used in A/C systems to lubricate the compressor. Most all newer model cars use PAG as the lubricant in the A/C system. The numbers represent the viscosity of the lubricant just as “10W-30” or “10W-40” represent the viscosity of motor oil.
Can you add too much PAG oil?
The oil absorbs this heat and keeps the AC components lubricated. The amount of oil should neither be lesser nor greater than the required amount. If you add too much oil to the system, it may pool in various places of the system and can coat the inner walls of the evaporator and condenser coils.
Is there such a thing as universal PAG oil?
Because the various PAG oils all have different viscosities, it is virtually IMPOSSIBLE to have a single oil formulation with the same viscosity characteristics as the original PAG 46, PAG 100 or PAG 150. The universal oil will be a compromise blend that fails to meet anyof the OEM specifications.
Where can I find PAG oil for my supercooltm compressor?
This information can also often be found on a tag in the vehicle’s engine compartment and/or on the compressor itself. For further information visit www.supercool.ac * PAG Blue — Delphi Harrison specifies 125-135 CSt PAG Oil for V5, V7 and H6 (plus service production Radial-4) compressors.
What’s the viscosity of Pag 46 motor oil?
PAG 46, PAG 100 and PAG 150 oils all have different viscosities, just as 5W-20, 5W-30 and 10W40 motor oils have different viscosities. You should not intermix different viscosities because the viscosity of the mixture may be “out of range” for the appliction for a number of reasons.
What can be used as a substitute for PAG oil?
PAO (Polyalphaolefin) oil can sometimes be used as a substitute for certain PAG oils if the compressor manufacturer approves it. CAUTION: PAG oils should NEVER be used in hybrid vehicles because it is electrically conductive.
What’s the difference between mineral oil and PAG oil?
Summary: Mineral Oil is used on R-12 systems, primarily on cars built prior to 1995. PAG OIL. Polyelkylene Glycol (PAG) oil is a synthetic oil used by OEMs in their R-134a systems. PAG oils are harsher than mineral oils, and may cause skin irritation and damage O-rings and seals.
