CITGO Pacemaker 1640AE is an SAE 40 low ash stationary natural gas engine oil and anti-emulsion
compressor lubricant. It is specially formulated to help prevent emulsion formation in high moisture
gas conditions. High moisture gas is prevalent in shale and coal bed methane (CBM) production
areas where water is introduced to the gas stream. This and other operating conditions can trigger
oil and water emulsion in compressor systems and cause operating issues. Conventional low ash
engine oils form emulsion under these conditions, requiring use of a separate compressor lubricant.
CITGO Pacemaker 1640AE helps avoid use of separate lubricants by mitigating compressor emulsion
without sacrificing engine protection. CITGO Pacemaker 1640AE complies with engine manufacturers’
warranties and meets non-selective catalytic converter requirements.

CITGO Pacemaker 1640AE is a specially formulated SAE 40 lubricant that provides superior engine
protection while avoiding emulsion formation in high moisture gas environments. CITGO Pacemaker
1640AE is recommended for a wide range of high and medium speed naturally aspirated and
turbocharged 4-cycle engines including those manufactured by Caterpillar, Waukesha, Superior,
Cooper-Bessemer, Cummins and Dresser Rand.
