Lubrication oils
High-quality, mineral, hydraulic or synthesized
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:
Note: Additional equipment is needed to run the
compressor below 18°F. A thermostatic bypass valve
arrangement that will bypass the compressor oil cooler,
along with synthetic oil, offers the best protection of the
compressor against cold weather related problems.

ENGINE OIL
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 excess heat efficiently, whilst
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 EURO -
3 & -2, EPA TIER II, TIER III & Tier 4i engines running
on low sulphur diesel for lower oil and fuel consumption.
PAROIL E is a mineral based high performance diesel
engine oil with a high viscosity index. Atlas Copco
PAROIL E is designed to provide a high level of
performance and protection in ‘standard’ ambient
conditions as from -5°C (23°F).

* If you want to use another brand of oil,
consult the engine instruction manual.
** It is strongly recommended to use Atlas
Copco branded lubrication oils for the
compressor.

Never mix synthetic with mineral oil.
Remark: When changing from mineral 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 good 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,
proceed as in normal instruction.
Operation of compressor in ambient
temperatures lower that 18°F (-10°C)
without the correct type of oil will void your
warranty and may result in element failure
and/or fire.
