I'm coming late to this party but I'll throw in my .02 cents. It is my personal opinion that compressor oil does not deteriorate or have an expiration date. My Alkin is 5 years old and only has 20 hours runtime total. I changed the oil after the first year but only change my oil every other year now since it's only running about 5 hours per year or less. Even after the last oil change at 2 years the drained oil looked almost as new.
IMHO, discarding a partially unused gallon of $80-160 compressor oil is like flushing cash down the toilet. The only beneficiary is the oil retailer. If anyone prefers to discard "expired" containers of Anderol 750 or Secolube 500 please send it to me and I'll dispose of it safely.
