Extending Engine Life and Reducing Maintenance through the Use of a Mobile Oil Refiner

The by-pass oil refiner, which removes both solid and liquid contaminants, has shown itself to be very effective in substantially extending the life of an engine. In twelve years of piloting and testing with school bus fleets, this author found the refiner to keep oil cleaner than either a full-flow or diesel by-pass oil filter can and, in doing so, eliminate the necessity of interval oil changes. Its use constitutes a major maintenance change: extended oil use results in a processing of oil and engine which can be accomplished in no other way.
