Routine oil changes in mobile equipment rear differentials cost time and money and do little to improve equipment reliability. The high viscosity oil drains slowly and leaves a trail of varnish, wear particles and dirt behind to contaminate the new oil. Cleaning the oil to OEM recommended levels with a depth filter media reduces contaminants like wear particles, water and varnish and extends the oil life while improving equipment reliability. In one example, oil life increased from 18,000 to 25,000 hours and wheel rebuilds decreased from 16 to 12 per vehicle per year thus saving ~$500,000 annually.
