Don't hear the word "meniscus" around here too often.
Short answer...iffn your level (at the base of meniscus) is between the lines, you (and your motor) are ok.
If you lose sight of the oil (too low) or the meniscus (too high) check closely to see where you're at and adjust accordingly.
If you fill the oil till the meniscus just disappears above the sight glass it is not a problem, maybe just a wee bit of blowby.
Take care, and mind the meniscus! :laugh:
