AMSOIL Synthetic ISO 150, SAE 50 Compressor Oil (PCL)
Synthetic PC Series Compressor Oil
(ISO 150, SAE 50)
The correct manufacturer-recommended
viscosity grade of AMSOIL PC Series
compressor oil is recommended for use in
rotary screw, rotary vane, reciprocating and
other compressor applications. Compatible with
PAO-, ester- and petroleum-based compressor
oils. They are not compatible with glycol- or
silicone-based compressor oils.
Package sizes include:

5-Gallon Pail
55-Gallon Drum
PRODUCT DESCRIPTION
AMSOIL PC Series Synthetic Compressor Oils are long-life, premium compressor lubricants
based on novel, proprietary technology. They incorporate the highest quality, thermally-stable
PAO synthetics fortified with premium non-detergent, ashless additives for maximum protection
at high temperatures and pressures. They last up to eight times longer than petroleum oils,
effectively reducing maintenance and waste oil disposal costs.

Improves Compressor Efficiency
AMSOIL PC Synthetic Compressor Oils have low friction properties and they resist viscosity
increase from oxidation. They help improve operating efficiency and save money on electrical
energy consumption.

Controls Foam and Reduces Wear
AMSOIL PC Compressor Oils contain anti-foam additives and, unlike other compressor oils, they
are anti-wear fortified. Good foam control reduces heat, oxidation and wear. High contact
regions are protected against wear for increased compressor life and efficiency.

Resists Water Contamination
Water from condensation builds up in compressors that can cause unwanted oil/water
emulsions, environmental discharge hazards and rust. AMSOIL PC Synthetic Compressor Oils
are hydrolytically stable. They resist acid formation, readily separate from water and are anti-
rust fortified. Water can be easily drained off for simplified environmental discharge and
increased oil life.

Resists Heat and Oxidation
AMSOIL PC Series Compressor Oils combine the inherent stability of premium synthetic base
oils with specialized anti-oxidant additives to resist varnish, carbon and acid formation. They
protect compressors better and last longer in service than petroleum oils, especially during hot
operating conditions.

Safety Advantage
AMSOIL PC Series Synthetic Compressor Oils are ashless, high flash point formulations with
very low carbonforming tendencies that minimize the incidence of ignition-promoting “hot spots.”
While PC Synthetic Compressor Oils can provide improved fire safety, they cannot be
considered non-flammable.

APPLICATION RECOMMENDATION
The appropriate viscosity of AMSOIL PC Series Synthetic Compressor Oil is recommended for
use in single and multistage rotary screw, vane, centrifugal and reciprocating compressor
crankcase and cylinders, vacuum pumps and other applications such as gears, bearings,
blowers, pumps and handheld pneumatic tools. In compressor applications, drain intervals of
8,000 hours or more can be expected under normal operation. Drain intervals are subject to
operating conditions and maintenance practices. Monitoring by oil analysis is recommended. For
best performance, AMSOIL recommends the compressor be drained prior to the installation of
PC Synthetic Compressor Oil. If carbon deposits are present on the internal components, it is
recommended they be removed following the compressor manufacturer recommendations.
