Valvoline Premium Blue Gen 2 One Solution 15W-40 is an advanced heavy-duty engine oil designed to deliver exceptional performance and protection across a wide variety of engine types and fuel sources. True to its name, this oil provides a single lubrication solution for fleets that operate vehicles powered by diesel, gasoline, liquefied petroleum gas (LPG), and compressed natural gas (CNG) engines.

This engine oil is specifically formulated for modern diesel engines equipped with exhaust emission aftertreatment systems. Its optimized sulfated ash content (0.7-0.9%) ensures compatibility with diesel particulate filters (DPF) and other emission control devices, preventing premature clogging and extending aftertreatment system service life. This makes Premium Blue Gen 2 particularly valuable for urban transit operators, delivery fleets, and service vehicles that must comply with strict emission regulations.

The advanced additive technology delivers comprehensive engine protection including excellent wear resistance during frequent start-stop cycles, superior deposit control that maintains engine cleanliness, and robust oxidation stability for extended drain capability. The oil also provides reliable soot handling and viscosity control, ensuring consistent performance even as soot loading increases between oil changes.

Premium Blue Gen 2 One Solution is ideal for city buses, delivery trucks, municipal vehicles, and mixed-fuel service fleets. It replaces and upgrades earlier Premium Blue formulations (8100, 8600, and 9200), offering improved performance across all key metrics. Fleet operators benefit from consolidated inventory, reduced purchasing complexity, and the confidence that a single product protects every engine in their diverse fleet, regardless of fuel type or emission system configuration.
