What's the 2009 bmw 528i oil type?

The 2009 BMW 528i uses a 3.0L 6 cylinder engine in all configurations, which requires the usage of 6.9 quarts of SAE 0W-30 synthetic engine oil. In a pinch, this can be substituted with SAE 5W-30, though its use over long periods of time isn't recommended. When it comes to an oil's weight, the numbers mean different things for viscosity. The first is viscosity at startup temperature, and the second is viscosity at operating temperature. Higher numbers mean a thicker oil; while You may not notice much difference, Your engine will. The 5W-30 will have Your engine working harder, which can lead to premature wear and tear. Even though the 0W-30 may cost a bit more, You'll thank Yourself in the long run.
