Synthetic Compressor Oil
AMSOIL SIROCCO® Synthetic Compressor Oil (SEI) is
recommended as a direct replacement for PAG compressor oils such as Sullair Sullube 32® and Ingersoll-Rand SSR
Ultra-coolant®. Not recommended for use with Silicone base fluids.

AMSOIL SIROCCO® Synthetic Compressor Oil is formulated with premium synthetic ester technology.
This high-quality, long-life fluid lasts several times longer in use than mineral-based oils. AMSOIL SIROCCO
Compressor Oil is fully formulated with non-detergent additives and is designed for use in rotary screw compressors
and vacuum pumps. SIROCCO effectively protects against wear, oxidation, foam and rust and has inherent lubricity
and good thermal conductivity which allow it to reduce heat and energy consumption. AMSOIL SIROCCO Compressor Oil
increases operating efficiency, reducing money spent on energy, repair and maintenance costs. AMSOIL SIROCCO
Synthetic Compressor Oil maintains performance across a wide operating temperature range. Its low pour point, high
viscosity index and lack of paraffins (wax) make it an excellent all-season lubricant. At high temperatures,
SIROCCO forms virtually no carbon, allowing for clean operation. At cold temperatures, equipment starts easier and
the lubricant is quickly pumped to critical components, preventing lubricant starvation and excessive wear. SIROCCO
Compressor Oil also resists water to prevent damaging oil/water emulsions, allowing for longer lubricant life and
ease of water removal from the sump.
- Resists foaming
- Rust and oxidation inhibited
- Readily separates from water
- Recommended for use in rotary screw compressors
- Long-life/extended drain performance
- Compatible with polyglycol fluids such as Sullair Sullube 32® and Ingersoll-Rand SSR Ultra-coolant®
AMSOIL SIROCCO Synthetic Ester Compressor Oil has higher flash, fire and auto ignition points than
competitive petroleum oils. Its resistance to carbon formation and the ashless additive system minimize the
incidence of deposits acting as ignition-promoting hot spots. Although AMSOIL SIROCCO Synthetic Compressor Oil
increases fire safety, it cannot be considered non-flammable.
AMSOIL SIROCCO Synthetic Compressor Oil is a multi-viscosity oil meeting the requirements of 5W-20. It may be used
in applications calling for either an ISO-32 or ISO-46 compressor oil or coolant. It is recommended for use in
single and multi-stage rotary screw compressors and vacuum pumps that call for this viscosity.
When installing AMSOIL SIROCCO Compressor Oil, 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 SIROCCO Compressor Oil has 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
AMSOIL SIROCCO Compressor Oil is compatible with and recommended as a replacement for much
higher-priced polyalkylene glycol (PAG) compressor oils or coolants such as Sullair Sullube® 32 and Ingersoll Rand
SSR Ultra Coolant®. No flushing is necessary when changing over from Glycol Coolants to AMSOIL SIROCCO Compressor
Oil. However, draining the system and changing the filters is recommended.
AMSOIL SIROCCO Synthetic Compressor Oil is recommended for use up to 8,000+ hours for most
compressor applications. However, this is subject to operating conditions and maintenance practices. Monitoring by
oil analysis every 1,000 hours is recommended.
AMSOIL SIROCCO Compressor Oil is compatible with petroleum oils, most synthetic oils*, and many seals, paints and
materials commonly used in compressors. Materials recommended and not recommended for use with SIROCCO Compressor
Oil are listed below.
