Specifications PAROIL
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, III & IV engines
running on low sulphur diesel for lower oil and fuel
consumption.
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.
It is strongly recommended to use
Atlas Copco branded lubrication
oils for both compressor and engine.

Never mix synthetic with mineral
oil.
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.
