Luber-finer has launched its new line of heavy-duty time-release technology oil filters. The line provides users with an oil management system that helps maintain oil quality and reduce maintenance costs associated with oil change intervals, according to Luber-finer. The filters have been specifically engineered to help heavy-duty fleets extend oil change intervals by increasing the protection against oil degradation in modern diesel engines by providing a controlled release of a specially formulated, highly concentrated liquid additive into the oil supply.
