Unique Formulation

The average compressor performs under very severe operating conditions. High heat and high pressure required to maintain satisfactory levels of compressed air can degrade internal compressor components and shorten any compressor's operating life. To ease the burden of operating stresses, a quality compressor oil is needed.
     AMSOIL PC Synthetic Compressor Oils are formulated from premium synthetic base oils and specialized additives. Its unique formulation allows AMSOIL PC Synthetic Compressor Oils to increase operational efficiency, reduce energy consumption, lower operating temperatures and be used in a wider operating temperature range. AMSOIL PC Synthetic Compressor Oils minimize carbon build-up and provide clean performance.

A Complete Additive System for Top Performance

AMSOIL PC Synthetic Compressor Oils are fortified with additives designed for compressor applications. Unlike other compressor oils, they are anti-wear fortified. The anti-foam agents stop unwanted foaming and air entrapment, the corrosion inhibitors protect internal parts against rust and corrosion, and the oxidation inhibitors increase lubricant life by preventing carbon formation and lubricant degradation.

Reduces Heat and Wear

Good foam control reduces heat, oxidation and wear. AMSOIL PC Synthetic Compressor Oil's anti-foam additives help keep high-contact regions protected against wear for increased compressor life and efficiency.

Reduces the Need for Frequent Repairs or Rebuilds

The ashless/non-detergent anti-wear additives found in AMSOIL PC Synthetic Compressor Oils prevent deposits and keep components in like-new condition, reducing the need for frequent repairs or rebuilds.

Longer Compressor Life

Due to the inherent stability of premium synthetic base oils, AMSOIL PC Synthetic Compressor Oils reduce friction and resist oil breakdown much longer than conventional compressor oils. These features provide better wear protection and cleaner performance, which translates to longer compressor life.

Saves Money on Energy Consumption

AMSOIL PC Synthetic Compressor Oils have low friction properties and they resist viscosity increase from oxidation, which helps improve operating efficiency and saves money on electrical energy consumption.

Eliminates Seasonal Fluid Changes

AMSOIL PC Synthetic Compressor Oils can operate in a wide operating temperature range -– they remain fluid in cold temperatures and have excellent stability in high temperatures. These features reduce the need for seasonal fluid changes, which means an overall savings for you.

Resists Water Contamination

Water from condensation builds up in compressors and can cause unwanted oil/water emulsions, environmental discharge hazards and rust. AMSOIL PC Synthetic Compressor Oils resist water to prevent damaging oil/water emulsions, allowing for better lubrication, longer lubricant life and ease of water removal from the sump -- water can be easily drained off for simplified environmental discharge and increased oil life. AMSOIL PC Synthetic Compressor Oils are anti-rust fortified.

Safety Advantage

AMSOIL PC Synthetic Compressor Oils have higher flash, fire and auto-ignition points than competitive petroleum oils. Their resistance to carbon formation and the ashless additive system minimizes the incidence of deposits acting as ignition-promoting hot spots. (Note: While AMSOIL PC Synthetic Compressor Oils can provide improved fire safety, they cannot be considered non-flammable.)

Best Overall Performance Score

When it comes to compressor oils, consumers have many different options. Many equipment manufacturers market their own brand of compressor oils. Other oils are available with a variety of chemistries. But not all oils meet all parameters of compressor operation. This is because unbalanced chemistries can work against each other and weaken certain performance requirements. To be truly effective at protecting a compressor from all of the stresses it faces, an oil must contain a balance of all the right features.
     For example, as illustrated in the chart below, even though a few competing oils performed slightly better than AMSOIL in the 4-Ball Wear Test, AMSOIL PCI (ISO 46, SAE 20) came out on top when overall performance in ALL areas of protection was considered. AMSOIL PCI received the best overall performance score, proving AMSOIL is the most versatile oil among the group tested. AMSOIL PCI consistently performed near the top of the charts in all 14 test comparisons, while other oils performed well in some tests but not in others.

AMSOIL Outperforms the Competition in Pricing

AMSOIL also outperforms the competition in pricing. One reason for this is that AMSOIL is sold factory-direct, eliminating the cost-increasing steps normally used in distributing other compressor oils. Some equipment manufacturers also have their own oils mentioned in their compressor warranties, allowing them to increase the prices charged for their "specialty" oils. AMSOIL can offer the best overall quality compressor oil and still provide the best price!

8,000-Hour+ Life Expectancy

AMSOIL PC Synthetic Compressor Oils reduce maintenance costs by extending drain intervals and lowering labor and used-product-disposal requirements. AMSOIL PC Synthetic Compressor Oils may be used for 8,000 hours or more for most compressor applications, subject to operating conditions and maintenance practices. Monitoring by oil analysis is recommended.

Note: When installing AMSOIL PC Synthetic Compressor Oils, it is recommended that the old oil be thoroughly drained and, if warranted, the system cleaned. If a lot of carbon or residue is found on the internal compressor parts, follow the manufacturer's recommendations for removal prior to installing the new oil. AMSOIL PC Synthetic Compressor Oils have a high level of solvency and may remove deposits left in the system. Check the filters and oil/air separators regularly for the first 500 hours of operation and replace as necessary.

Product Compatibility

AMSOIL PC Synthetic Compressor Oils are compatible with petroleum oils, most synthetic oils**, and almost all seals, paints and materials commonly used in compressors (see chart below). It is suggested that the compressor be thoroughly drained and cleaned if warranted, and the filter be changed prior to filling with the new lubricant. Cleaning should be done in accordance with manufacturer's recommendations. Consult AMSOIL technical department where further recommendations are needed.
     AMSOIL PC Synthetic Compressor Oils are not recommended for "breathing air" or refrigeration compressors; they are also not recommended for use with polycarbonate plastic that is not metal covered, PVC plastic, butyl, ethylene-propylene and SBR rubber.

**Not compatible with polyalkylene glycol or silicone oils such as Sullair 24KT®, Sullube 32® and Ingersoll Rand SSR Ultra Coolant.

Viscosity Grades and Applications

AMSOIL PC Synthetic Compressor Oils are available in five viscosity grades: ISO 32, ISO 46, ISO 68, ISO 100 and ISO 150. AMSOIL PC Synthetic Compressor Oils are recommended for use in single and multi-stage rotary screw, vane, centrifugal and reciprocating compressor crankcases and cylinders, vacuum pumps and other compressor applications (ISO/viscosity grade depends on application). In addition, the correct viscosity may be used in light-duty gear and bearing applications, blowers, pumps and hand-held pneumatic tools.
