Phillips 66® Multiplex FS ELL is a premium quality, synthetic, semi-fluid extreme pressure (EP), lithium complex grease specially developed for the lubrication of wheel bearings on non-driven trailer axles equipped with oil seals. It is formulated to help optimize service intervals and reduce operating costs by providing effective lubrication and cooling of wheel bearings exposed to prolonged high operating temperatures. It is also recommended for use in industrial gearboxes operating at high temperatures where oil leakage is a problem and conventional semi-fluid greases do not provide adequate service life.

Multiplex FS ELL is manufactured with a high viscosity synthetic polyalphaolefin (PAO) base oil and a lithium complex soap thickener. It is fortified with EP and antiwear additives plus rust and oxidation inhibitors to provide excellent wear protection, corrosion resistance, and long service life. It has outstanding thermal stability at high temperatures and outstanding pumpability at low temperatures for use over a wide temperature range.

    (1)Note: Multiplex® FS ELL is formulated to provide long service life, typically coinciding with scheduled brake service. However, we recommend that you refer to the Preventive Maintenance Inspection (PMI) Guidelines published by the Technology and Maintenance Council (TMC) of the American Trucking Association for relubrication practices. This document provides the following general guidelines for relubrication of wheel bearings in over-the-road trucks:
  • “A” PM – 60 days or 25,000 miles
  • “B” PM – 180 days or 50,000 miles
  • “C” PM – 360 days or 100,000 miles
