Abstract: An engine oil including a base oil in a range of about 70 to 85 wt %. The engine oil includes at least one additive in a range of about 15 to 30 wt %, such as, an antioxidant, a cleaning agent/detergent, a dispersing agent, a wear resistant agent, a viscosity index improving agent, a pour point depressant, a rust/corrosion inhibiting agent, a foam inhibiting agent, and an extreme pressure agent. The engine oil further includes an additive including an organometallic compound of a catalyst consisting of a catalytic element in a range of about 0.001 to 0.05 wt %.

Abstract: An aftertreatment system for treating a high-volume exhaust flow is provided. The aftertreatment system includes a filter module. The aftertreatment system also includes a conduit in fluid communication with the filter module. The aftertreatment system further includes at least one aftertreatment module in fluid communication with the conduit. The filter module is adapted to selectively receive at least one filter element therein. The at least one filter element is adapted to reduce a backpressure within the aftertreatment system. The filter module is also adapted to provide incremental levels of particulate matter reduction from the exhaust flow based, at least in part, on a number of filter elements therein.
