Found oil in front rails

Cruiz · 07-02-2022, 12:50 AM

I just got my 2018 M3 and I found these oil-like residue in the front rails. The residue is inside the hole which is weird. Any thoughts?

Nothing to worry about, that stuff is actually part of the shipping/anti-corrosive process

This stuff oozed out where the driver's door met the guard of my dad's brand new Z4 like crazy for the first few months back in 2012.

It's called cosmoline and it's perfectly normal. They try to clean it all out during make-ready, but it remains in areas that they can't reach. The heat from the engine eventually causes it to "migrate" into visible areas. Cleans up with a mild solvent like Goof-Off or similar.
