“Many of the modern heavy-duty engines equipped with EGR and SCR technologies generate higher levels of organic and inorganic acids, as well as higher amounts of soot in the oil,” says John Gaither, director of heavy-duty product engineering for Luber-finer. “This requires modern filtration technologies to address these newer challenges.”

One of the benefits of monitoring engine oil analysis data is the appropriate selection of an oil filter. “Fleets should know their engines, whether they are acid challenged or soot challenged, before making a decision to select a filter,” Gaither says.

“Luber-finer makes a Time Release Technology filter that is designed for acid challenged engines. Keeping an eye on the oil analysis data, understanding an engine’s behavior and intelligently selecting a filter can optimize engine life in addition to service intervals,” Gaither explains.

Filter choice and filter replacement should be based on engine oil analysis data. The Total Base Number (TBN) for oil, its acid-neutralizing reserve, degrades over time and miles, especially in modern diesel engines that use Exhaust Gas Recirculation (EGR). The Total Acid Number (TAN) measures the acidity level of the oil. The specially formulated liquid additive in Luber-finer TRT oil filters is continuously metered into the oil supply, helping the oil maintain stability. Any decision regarding extending oil drain intervals must be based on oil analysis and adherence to OEM criteria for acceptable oil operating properties. Operating properties may include, but are not limited to, TBN, viscosity and fuel dilution.
