- Available in NLGI #1, #2 or #3 (Note #1 is thinnest and #3 is thickest)


Schaeffer's 238 Ultra Supreme NLGI #1, #2 & #3

Schaeffer’s Ultra Supreme is a multi-purpose, tacky, para-synthetic, extreme pressure anti-wear aluminum complex base grease that is especially formulated for use in all types of heavy duty automotive, construction, mining, farming and industrial equipment, pin and bushing and fifth wheel applications that are being used under adverse conditions of excessive pressure, high shock loading, extreme hot and cold temperatures and moisture.

Ultra Supreme is compounded from the finest select severely hydro-treated polyalphaolefin (PAO) synthetic base fluids and high viscosity index solvent refined severely hydro-finished 100% paraffin base stocks.The molybdenum disulfide and solid lubricant package allows the Ultra Supreme to act as a "backstop" lubricant when the grease base is either destroyed or wiped away. This solid lubricant film will withstand pressures up to 500,000 pounds per square inch.

Ultra Supreme also has superior cohesive and adhesive properties. Ultra Supreme will not wash out, pound out, splatter or squeeze out even under the heaviest loads or vibrations.


  • Excellent resistance to water washout and water spray-off.
  • Excellent anti-wear and extreme pressure load carrying properties.
  • 100% reversibility. This property allows Moly Supreme to have the ability to retain its grease-like consistency and remain in the bearings during periods of heat, high shock loading, extreme pressure, and severe mechanical action.
  • Excellent rust and oxidation inhibiting characteristics.
  • A high dropping point.
  • Low temperature pumpability characteristics.


Due to its superior cohesive and adhesive properties Ultra Supreme is not recommended for use in passenger car automotive wheel bearings and electric motor bearings.

Ultra Supreme meets and exceeds the following specifications and manufacturer’s requirements: US Steel 346, 352, 355, 370 371 specifications, Caterpillar MPGM, Caterpillar’s 5% Molybdenum Disulfide Requirement for pin and bushing applications, Komatsu, MIL-G-234C, Case-IH 251H, John Deere, New Holland, Ford M1693A, General Motors, Chrysler, P&H 472B, 472C and 472D, Federal Specification VV-G-632A, MIL-G-4343C, MIL-23549C, DOD-G-24508A (Navy), JIS K2220, DIN 51825, SKF, Fag, INA, Torrington, Timken, Rexnord Link-Belt Bearing Division, Koyo, NTN Bearing, and Roller Bearing Company of America.
