Below are the AMSOIL oil and filter recommendations for your 2026 Mercedes-Benz G550 with the 3.0L 6-Cylinder.
2026 MERCEDES-BENZ G550 3.0L 6-CYLINDER ENGINE CODE 256.830 4
Your 2026 Mercedes-Benz G550 is powered by the 3.0L turbocharged six-cylinder, a modern engine that blends the smoothness of Mercedes' classic sixes with the torque of forced induction. It is the powertrain behind many of the brand's most popular models.
A turbocharged six-cylinder runs hot by nature, and heat is what stresses oil more than anything else. The turbocharger's bearings spin at extreme speed on a film of oil, while the engine itself generates high oil temperatures under boost. Oil has to stay in grade through all of it.
AMSOIL's full synthetic European formulas are designed for exactly this kind of engine. They resist high-temperature breakdown, hold their viscosity under boost, and keep the G550's turbo and internals protected across the full change interval. It is the oil care a modern Mercedes deserves.
The 2026 Mercedes-Benz G550 3.0L 6-Cylinder requires 0W-20 full synthetic motor oil. Capacity is 9.5 quarts including filter.
