Special seashore that - Labrador current meets Gulfstream and that heavy fog comes in sideways and keeps flogging you for a long, long, time ...

I don't know but a quick Google search shows it affects nearly every vehicle manufacturer. It may look nasty but truly is a non issue as long as it's not coolant.

Less fuel used, so less moisture into the sump? Gas has to run real rich at cold start, not sure that diesel has to run nearly as rich.
 
My limited understanding on HEUI direct injection engines has fuel dilution issues, is it alright to assume DI diesel generally runs rich ? IDK.
