CITGO Sentry Oils are a complete line of well-refined, non-additive mineral oils for bearing and other general purpose lubrication.
They are made from high viscosity index base stocks having low carbon residues and high flash points.
Available in several viscosity grades, these oils provide good lubrication with low maintenance costs, and have the necessary characteristics to permit their use in many applications.
CITGO Sentry Grades 15, 32, 68 and 460 are straight base stocks. All other grades are composed of base stock blends.
