Can you put to much oil in compressor

[Dead Parrot]

2nd the drain and refill with proper amount before getting too concerned about leaks. That shaft seal is probably well above the "full" level on the glass. Can't leak much just sitting there if the oil level is correct.

Even if it keeps leaking, unless it is a lot, a small pan full of that spill pickup stuff will last a long time.

Walmart around here still sells non detergent 30w. Its not the Detroit Diesel stuff but still good for filling your generic oil cans.
