Premium Blue is designed specifically for newer engines with advanced emissions systems, while All-Fleet Extra works well with both old and new diesel engines. Consider your vehicle’s needs before choosing between these two options.

In addition to its excellent quality, Valvoline 15 40 Diesel Oil also offers great value for money. It comes in both gallon and five-gallon containers at competitive prices compared to other synthetic blend oils in the market.
