CITGO Pacemaker Oils are rust and oxidation (R&O) inhibited oils. They are general purpose lubricants, sometimes described as circulating oils, turbine oils, hydraulic oils or bearing oils. They contain defoamer and are readily separable from water, i.e., highly demulsible.

They are manufactured from high viscosity index base stocks.

These oils are made from selected high quality, paraffinic base stocks.

Their high viscosity index imparts superior temperature-viscosity characteristics. Long service life in closed circulating systems is assured by low carbon-forming tendency and excellent resistance to oxidation, rusting and foaming.
