Synthetic PC Series Compressor Oil (ISO 68, SAE 30)
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. Consult AMSOIL for further information.

Reference Guide (68k PDF)
AMSOIL PC Series Synthetic Compressor Oils are longlife, 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.
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.
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.
