Cermax Ceramic Synthetic Motor Oil 15W-40 and 10W-30 diesel viscosities are formulated to meet applicable API CK-4 specifications
Best practice for high-mileage engines: (1) Consider using Cermax 10W-30 or 10W-40 instead of thinner viscosities IF your owner's manual permits — thicker oil helps compensate for accumulated wear in some older engines
Compatible with both pre-mix systems (where you manually mix oil into gasoline) and oil-injection systems (where the engine meters oil from a separate reservoir)
and OEM compatibility
