Oil specifications
It is strongly recommended to use Atlas
Copco branded lubrication oils for both
compressor and engine.
Only use synthetic compressor oil.
High-quality,
mineral,
hydraulic
hydrocarbon oil with rust and oxidation inhibitors, anti-
foam and anti-wear properties is recommended. The
viscosity grade should correspond to the ambient
temperature and ISO 3448, as follows:
Never mix synthetic with mineral oil.
Remark:
After a complete change over to synthetic
oil (or the other way around), you will need
to do an extra rinse:
After doing the complete change procedure
to synthetic oil, run the unit for a few
minutes to allow proper and complete
circulation of the synthetic oil.
Then drain the synthetic oil again and fill
again with new synthetic oil. To set correct
oil levels, follow the normal instructions.
PAROIL from Atlas Copco is the ONLY oil tested and
approved for use in all engines built into Atlas Copco
compressors and generators.
Extensive laboratory and field endurance tests on Atlas
Copco equipment have proven PAROIL to match all
lubrication demands in varied conditions. It meets
stringent quality control specifications to ensure your
equipment will run smoothly and reliably.

The quality lubricant additives in PAROIL allow for
extended oil change intervals without any loss in
performance or longevity.
PAROIL provides wear protection under extreme
conditions. Powerful oxidation resistance, high chemical
stability and rust- inhibiting additives help reduce
corrosion, even within engines left idle for extended
periods.
PAROIL contains high quality anti-oxidants to control
deposits, sludge and contaminants that tend to build up
under very high temperatures. PAROIL's detergent
additives keep sludge forming particles in a fine
suspension, instead of allowing them to clog your filter
and accumulate in the valve/rocker cover area.
PAROIL
releases
maintaining excellent bore-polish protection to limit oil
consumption.
PAROIL has an excellent Total Base Number (TBN)
retention and more alkalinity to control acid formation.
PAROIL prevents Soot build-up.
PAROIL is optimized for the latest low emission Stage
IIIB, 3 & 2, TIER 4 Interim, 3 & 2 engines running on low
sulphur diesel for lower oil and fuel consumption.
PAROIL E xtra is a Synthetic ultra high performance
diesel engine oil with a high viscosity- index. Atlas Copco
PAROIL E xtra is designed to provide excellent
lubrication from start-up at temperatures as low as -25°C
(-13°F).
PAROIL E Mission Green is a mineral based high
performance diesel engine oil with a high viscosity- index.
Atlas Copco PAROIL E Mission Green is designed to
excess
heat efficiently, whilst
- 57 -
provide a high level of performance and protection under
'standard' ambient conditions from -10°C (14°F) onward.
PAROIL E xtra and PAROIL E Mission Green are low
SAPS oil. These oils are to be used in Stage IIIB / Tier 4
Interim engines in order to provide the full performance
and life of the engine and aftertreatment systems.
