Tiny bubbles in oil?

[J51S]

Recently Ive just been flushing out my 05 with oil and letting it idle and drain. (using rotella) Changed the filter and filled her up. Let it idle for like a minute. I looked threw the watch glass to check color and it looked like it was a bunch of tiny bubbles. The color looked good it just seemed weird thats theres all these bubbles.

This normal? this is my first 450

i sure but i think you put to much oil in causing the crank to splash the oil causing the oil to bubble

I noticed that specifically when running the Dino 15-40 in the white bottle, but not in other oils, call me crazy or whatever..... I know the oil is fully vetted and there are far too many running it to be an issue. I also run it in numerous machines with great success.

The oil is getting pumped / squirted round inside engine... perfectly normal. Nothing to worry about.

pop them all one at a time and you should be just fine. :D
