How come i getting strong smell of oil in my BMW 525?

A strong smell of oil in your BMW 525 could indicate a potential oil leak, which might be due to a worn gasket, seal, or a loose oil filter. It's also possible that oil is burning on a hot engine component, such as the exhaust manifold. To ensure safety and prevent further damage, it's advisable to inspect the engine for leaks and check oil levels, and consider visiting a mechanic for a thorough diagnosis.
