Below are the AMSOIL oil and filter recommendations for your 2008 Mercedes-Benz GL550 with the 5.5L 8-Cylinder.
2008 MERCEDES-BENZ GL550 5.5L 8-CYLINDER ENGINE CODE 273.963 0
The 2008 Mercedes-Benz GL550 with the 5.5L V8 is the classic American-market Mercedes formula: a big, torquey eight-cylinder in a chassis built for the Autobahn. These engines have powered everything from luxury sedans to AMG performance models.
V8s run hot and pull hard, and both traits stress the oil. Heat breaks down conventional oil over time, leaving varnish and sludge that clog oil passages and shorten engine life. High load demands film strength that cheap oil cannot sustain.
AMSOIL full synthetic oil resists that breakdown and keeps the GL550's V8 clean inside. Its high-temperature stability and anti-wear chemistry protect the engine across the full service interval, which is exactly what a hard-working eight-cylinder needs.
The 2008 Mercedes-Benz GL550 5.5L 8-Cylinder requires 5W-40 full synthetic motor oil. Capacity is 9.5 quarts including filter.
Here is what you need:
You need 9.5 quarts of AMSOIL 5W-40 FS 100% Synthetic European Motor Oil EFMQT-EA which you can learn more about here: AMSOIL 5W-40 European motor oil
You need the AMSOIL nano fiber long life oil filter for your GL550 which is: EA15K39
Drain Plug Torque Spec: 22 ft/lbs - always replace the drain plug seal when changing oil.
