Fluctuation in oil level

I have oil fluctuation in the sight glass after I change the oil.

James, as long as the oil in my sight glass is at the "full" level, I don't worry about whether vibration makes the level fluctuate.

If, on the other hand, the oil level fluctuated to a too low level, that would be a concern.

How much fluctuation, within the "full" parameters?

If it stays near the full mark, and it were my compressor, I wouldn't worry about it.

Other comments (even if they disagree) are welcome.

Nice photo. Thanks.

Cheers,

Bill
