Engines are normally equipped with an oil filter which removes particles between 10 and 25 microns in size. An additional ultrafilter can capture particulate contamination down to 0.5 microns. By keeping contaminants out of lubricating oil, ultrafilters extend the oil's life. Additive Packages and High grade Oil - Lubricating oil is produced from a mixture of base stock and additives. Additives help keep the oil clean and prevent viscosity breakdown and acid buildup.
Additives lose their ability to perform through normal service life.
Oil analysis indicates to the operator when additives are needed. High grade oils contain greater amounts of additives and are less susceptible to oxidation, both of which allow the oil to perform longer. Confirm that your used oil transporter has an EPA identification number and know where your used oil is taken after it leaves your facility. Keep records of each off-site shipment and any chemical analysis of your used oil. Do not mix hazardous waste with your used oil.
