  CITGO              SYNTHETIC                       GEAR              LUBRICANTS



  Date 10/06





DESCRIPTION:         CITGO Synthetic Gear Lubricants are heavy-duty, synthetic gear and bearing lubricants designed for

                     use in manual transmissions, transfer cases and differentials of passenger cars, trucks, farm tractors,

                     construction and miscellaneous other industrial equipment. Blended from high viscosity index, low

                     pour point synthetic base stocks, these oils provide maximum protection to gears and bearings

                     operating over a wide range of temperatures, speeds and loads. Their superb resistance to oxidation

                     provides the benefit of extended drain intervals. Available in three viscosity grades: SAE 75W-90,

                     80W-140 and 50.





 PROPERTIES:         � Superior oxidation resistance for extended drain intervals.

                     � Excellent load carrying properties (SAE 75W-90 and 80W-140) for maximum protection

                       against component wear.

                     � High viscosity index and low pour point synthetic base stocks provide reduced fluid friction with

                       resultant fuel savings potential during low temperature start-up or operating conditions.

                     � Excellent demulsibility � separates water readily.

                     � Shear resistant.

                     � Provides full protection to system parts against rust and corrosion.

                     � Non-foaming.





                     CITGO Synthetic Gear Lubricants (SAE 75W-90 and 80W-140) are recommended for differentials,

APPLICATIONS:

                     manual transmissions for which hypoid-type lubricants are required and transfer cases for heavy

                     equipment � trucks, tractors, industrial gear drives, automobiles, farm machinery, etc. These products

                     meet or exceed the following performance requirements:

                     � API Service Classification GL-5 and MT-1

                     � SAE J2360

                     � U.S. Military Specification MIL-L-2105D and MIL-PRF-2105E

                     � Scania STO 1:0

                     � Eaton Roadranger E500/Shaes 256

                     � Mack GO-J Plus (75W-90)

                     � Mack GO-J (80W-140)

                     � ArvinMeritor O-76N

                     � International TMS-6816

                     � General Electric D 50E9C

                     � Harnishfeger (P&H) 474

                     CITGO Synthetic Gear Lubricant SAE 50 is recommended for heavy-duty service in manual

                     transmission for which the manufacturer normally recommends either engine oils or GL-1 to GL-4

                     lubricants. This product contains antiwear, rust, oxidation, foam and corrosion inhibitors to protect

                     bearings and synchronizers and to promote longer transmission life. As in the other products in this

                     series, CITGO Synthetic Gear Lubricant SAE 50 provides improved start-up, easier shifting and less

                     gear wear in low temperature environments. Less friction, less drag and improved oxidation resistance

                     combine to provide fuel economy benefits and longer drain intervals.
