Oil misting from dipstick tube - blowby?

The initial oil dumped was 5quarts Mobil 1 synthetic 5w-30 with a added bottle of Lucas zinc Break In additive - I know this wasn't anywhere close to the proper way to do it.

I'm going to change over to standard 10w-30, as the initial oil and filter should come out now anyway, and I will report back

I never use synthetic to break in, use regular oil with the additive and a breather cap. Synthetic is good for after break in. I had trouble with synthetic and the rear main seal with a very minor leak. I returned to regular and no more leak. That stuff is really slippery!!
