How Do ECO MicroFilters Reduce Operating Costs?
When an ECO MicroFilters device is attached to the engine, the oil is continuously recycled through the microfilter. When the microgrit is continuously filtered out of the oil, CSP does not build up, as measured by the oil’s ISO Cleanliness Codes at or greater than 4 microns (≤ 4mµ) based upon laboratory particle count analysis. Clean oil reduces costs in two ways: (1) it reduces the annual costs of oil service by extending the oil drain interval. This reduces costs for lubrication oil, labor, shop time, and oil service parts and supplies; and, (2) Engine wear is reduced. The life of the engine is doubled, even when the oil drain interval is extended because the clean oil reduces engine wear, even at extended oil drain intervals. This is especially important to fleets because the cost to rebuild or replace sophisticated modern engines is higher than the cost to replace or rebuild an older pre-EGR diesel engine.What is the ECO MicroFilters Return on Investment?
The ROI is generally less than twelve months. Often ECO MicroFilters pay for itself in 4 to 6 oil changes, depending on service duty and other oil service costs. The cost savings for transit buses range from approximately $350 per year to $1,000 or more per vehicle/year depending on the equipment and service duty.How Can I Determine the ROI for Our Fleet?
Our ECO MicroFilters team will provide without cost a fleet savings projections for any fleet with 50 or more vehicles. Please contact us. We will provide a custom fleet cost savings analysis based upon your specific equipment, labor rates, costs, and service duty.What are the Preventative Maintenance Benefits?
A fleet can reduce approximately one-half of its oil services and provide better engine protection. Reducing the time in a scheduled maintenance for oil “pit trips” saves time and money, and allows the fleet supervisor to assign his or her skilled professionals to higher maintenance tasks. This improves facility utilization and allows mechanics to work on higher priority maintenance issues.Will ECO MicroFilters Reduce Costs in Natural Gas and Diesel Engines?
Yes. ECO MicroFilters will reduce costs in any engine, including Compressed Natural Gas (CNG), Liquid Natural Gas (LNG), diesel, bio-diesel, gasoline, and alternative fuel engines. Modern engines operate at higher combustion chamber temperatures and at closer tolerances. The closer tolerances require cleaner oil, free of CLP contaminants. The benefits of micro-clean oil are universal with all engine fuels.Do Microfilters Reduce EGR Lubrication Costs?
Yes. Exhaust Gas Recirculation (EGR) is a NOx (nitrogen oxide and nitrogen dioxide) reduction technique. EGR engines discharge less soot into the air and reduce NOx. Microfilters are ideally designed to remove the higher levels of soot in EGR engines, producing major cost savings by keeping the oil cleaner, longer.
What is the Relationship between Particle Contamination and Engine Wear?
As discussed earlier, General Motors published a SAE technical study on the relationship between level of particle contamination and engine life. The full-flow filter removes particles down to approximately 40 microns. As filtration is increased to down to 30, 20, 10, and 5 micron, the life of the engine components more than doubles as shown below:
ECO MicroFilters remove particles contaminants from 1 to 10 microns at high efficiency and down to 4 microns with absolute efficiency with high retention, which allows them to be used for a full oil drain interval at high efficiency without clogging.What are Wear Metals?
As engines operate, engine wear and friction sheds small amounts of wear metals into the oil. To build engines, several different types of metals are required, including aluminum, iron, and lead. As the engine wears, small amounts of aluminum, iron and lead build up in the lubricating oil.Will the Rate of Wear Metal Per Mile Decrease with ECO MicroFilters?
Yes. ECO MicroFilters decrease the wear metal rate per mile. In one controlled test on twenty-five transit buses, the rate of wear metal production in buses equipped with microfilters was reduced to approximately half the rate per mile of wear metal production produced in the control buses without the microfilters. These fleet findings correlate with the GM report that reducing particle contamination will reduce engine wear.How much is the Source Reduction of Hazardous Used Oil?
ECO MicroFilters source reduction is 50% or higher. The amount of source reduction depends on the amount of engine oil and the number of times the oil is changed per year. As an illustration, in a fleet of 100 transit buses with 12 oil changes per year and 9 gallon engine sumps, the reduction would be approximately 71 gallons per bus and 7,100 gallons per year for the fleet.How Much Conservation of Engine Oil is Achieved?
Source reduction of hazardous waste oil is directly connected with reduced lubricating oil consumption. For every gallon of hazardous waste oil which is not created, one gallon of non-renewable petroleum based lubricating oil is conserved.
