what kind of motor oil does a 2006 bmw 750 li use
Found a link that should give you the info you need, also more... in case you bought your car second hand and came without a manual... :(.http://www.bmwusa.com/Standard/Content/Owner/SyntheticEngineOils.aspx
Look in your owners manual. It specifies the type of oil.
Open your glove box, and look in the owners manual.
Your owner's manual should tell you. If you don't have one, you can download one online. :o
Synthetic 10w30, but always check your owners manual.
