2015 MERCEDES-BENZ GLK250 2.1L 4-CYLINDER ENGINE CODE 651.912 7
Your 2015 Mercedes-Benz GLK250 runs the 2.1L four-cylinder diesel, the workhorse layout Mercedes used for decades across its passenger cars and vans. These engines earned a reputation for covering huge mileages when they are looked after, and oil is the biggest part of that care.
A diesel works harder on its lubricant than a gas engine does. Compression is higher, combustion pressures are heavier, and the fuel leaves soot behind that has to be suspended in the oil until the next change. Diesel oil also has to handle long service intervals without losing its detergent chemistry.
That is why AMSOIL formulates diesel oils with extra soot control, high detergency, and strong film strength. For the 2015 GLK250, running a quality full synthetic on a consistent schedule keeps the injection system, bearings, and valve train in the shape that made Mercedes diesels famous.
The 2015 Mercedes-Benz GLK250 2.1L 4-Cylinder requires 0W-30 full synthetic motor oil. Capacity is 6.9 quarts including filter.
