Can German Castrol be used in a new car? The reason why I ask this is because it does not have the starburst symbol on the bottle and in my owner's manual an accepable motor oil has to have the API starburst symbol, and be of the correct viscosity.
I have no questions that the German Castrol is a great motor oil. But will using it void my warranty?
