Quinsyn Compressor Oil Guide & Replacement Oils

Quinsyn Compressor Oil Guide & Replacements

Quinsyn Compressor Oils: What’s the Difference?

Quinsyn is a family of compressor lubricants used across different Quincy compressor applications. If you’re searching for Quinsyn oil, you’re in the right place. Quinsyn isn’t one oil. It’s a family of compressor lubricants used across different Quincy compressor applications and operating demands.

Using the wrong Quinsyn oil can shorten oil life, increase varnish buildup, or create compatibility issues during an oil change. This guide breaks down the most common Quinsyn oil types so you can confidently choose the right one for your compressor.

Quinsyn Synthetic Compressor Oils

Quinsyn Plus (PAO)

Quinsyn Plus is a PAO-based synthetic compressor oil used in many rotary screw compressor applications. PAO synthetics are known for clean operation, strong oxidation resistance, and longer service life than conventional oils.

PAO synthetic base oil
Strong oxidation and varnish resistance
Designed for demanding rotary screw compressor duty cycles

Quinsyn IV (PAO)

Quinsyn IV is also a PAO-based synthetic oil. It is typically selected where PAO chemistry is required and where clean, stable performance is important for long run times.

PAO synthetic base oil
Thermally stable and clean-running
Common in continuous-duty compressor use

Quinsyn PAG Compressor Oils

Quinsyn Prime (PAG)

Quinsyn Prime is a PAG-based compressor lubricant. PAG oils are often chosen for specific compressor designs and operating conditions, including high heat and heavy loads.

PAG base oil
Excellent lubricity and cleanliness
Application-specific and chemistry-sensitive

Important: PAG oils are typically not compatible with PAO or petroleum oils. Do not mix oil types.

Quinsyn PG (PAG)

Quinsyn PG is also a PAG-based compressor lubricant used where PAG chemistry is specified.

PAG base oil
Designed for cleanliness and load handling
Not compatible with most PAO or mineral oils

Important: Always confirm compatibility and changeover procedures before switching to or from PAG lubricants.

Quinsyn POE Compressor Oils

Quinsyn Edge (POE)

Quinsyn Edge is a POE-based compressor lubricant. POE oils are chemistry-specific and are used where POE performance is required.

POE base oil
Designed for clean performance in demanding environments
Compatibility must be confirmed before switching

Reciprocating Compressor Oils

Quincip D (DSL) for Reciprocating Compressors

Quincip D is a DSL-type oil used for reciprocating compressors. Reciprocating compressors have different lubrication needs than rotary screw compressors, so it’s important to match oil type and viscosity to the application.

Quincip 100 (Petroleum)

Quincip 100 is a petroleum-based compressor oil commonly used in certain reciprocating and legacy compressor applications.

Petroleum (mineral) oil formulation
More frequent oil changes than synthetic lubricants
Often found in older or conventional maintenance programs

Choosing the Right Quinsyn Oil

The right Quinsyn oil depends on:

Compressor type (rotary screw vs reciprocating)
Oil chemistry required (PAO vs PAG vs POE vs petroleum)
Operating temperature and duty cycle
OEM specifications and service expectations
Changeover requirements and compatibility

Matching the oil to the application and chemistry is what protects your compressor and keeps your maintenance predictable.

Quinsyn Oil Replacements

We carry high-quality replacement compressor lubricants that match Quinsyn chemistry and performance requirements. These oils are selected for clean operation, consistent protection, and long service life.

Direct Replacement Lubricants for Quinsyn Oils

Many facilities search for terms like “Quinsyn equivalent”, “Quinsyn replacement oil”, or “direct replacement lubricant for Quinsyn”. In most cases, they are not looking to change how their compressor operates. They are looking for a lubricant that delivers the same protection and service life without being tied to OEM branding.

A true direct replacement lubricant is selected by matching:

Oil chemistry (PAO, PAG, POE, or petroleum)
ISO viscosity grade
Oxidation and deposit control
Expected drain interval and operating conditions

When those match, a replacement oil performs the same function inside the compressor.

Compatibility and Changeover Notes

Do not mix lubricant chemistries. Compatibility matters.

PAG lubricants are typically not compatible with PAO or petroleum oils
POE lubricants are chemistry-specific and should not be swapped without confirming requirements
Petroleum oils should not be mixed with synthetics without proper changeover procedures

If you are switching oil types, follow the proper changeover process for your compressor to avoid contamination and performance issues.
