Need help engine oil contamination

Guys got a c13 and when I pull the dip stick the very tip of the dipstick had a whitish residue but the oil itself is fine.

I’m so confused my oil is find but every tip I put dipstick back it the tiny part of tip comes back with whitish residue

 

I ran it from Chicago to nj non stop oil temp is around 200-210 max and water temp is 180-190

Tells me its probably running cold or idling a lot.[/QUOTE]

 

Guys on my way back to Chicago right now running in mountain I stopped to Check again and this time it didn’t have any residue nothing at all so weird.

Iattached a pic of my dip stick currently.

I will check again in a few hours and see if it’s changed if so attache another pic
