What type of oil do you use with R-134a?

So, along with R134a came a new oil: Polyalkylene Glycol—or PAG oil. Note that there is another kind of oil called Polyol Ester Oil (POE). The advantage of ester oil is that it works with both R12 as well as R134a, so you can fill the system with it and then use either refrigerant.

What kind of oil does an air conditioner compressor use?

Automotive air conditioning compressors require specific types of lubricants. Most 1996 and newer A/C systems use R134a refrigerant and require some type of PAG (polyalkylene glycol) oilfor the compressor. If the wrong type of compressor oil or the wrong viscosity compressor oil is used, it may damage the compressor.

What do you need to know about compressors and lubricants?

Specs are for total system capacities. Always refer to under hood decal as the primary source for refrigerant and lubricant information.

Can a low oil level cause a compressor to fail?

Use the following guidelines for replacing compressor oil when changing A/C components: Compressor………1.4 oz Condenser……….1.0 oz

Can you use mineral Oi L in an A / C compressor?

Mineral oi l should only be used in older R-12 A/C compressors because R-12 will not mix with R-134 refrigerant. “Universal” A/C compressor oils are often PAO-based and are not the same viscosity as the PAG oil recommended for a specific type of compressor.
