    Oil sample to know for sure and give you a warm and fuzzy. I see nothing to raise concern as water droplets and condensation from temperature changes is normal. Service the crankcase filter with a new element and thoroughly clean the housing out.

    Sorry to disagree but I would be very concerned only time I’ve seen anything like that is when you’re getting water in your oil that’s not just a few droplets !
