so i finally whipped this together.
fill time of a york 210. Two 5 gallon tanks making 10 gallons. I apologize for the bad video quality. Since the gauges are hard to see in the video the PSI numbers will be displayed at the bottom. Also i tried to keep the revs between 1500 to 2000, but even when i hold the pedal in one spot the revs will still drop.

Before the test I drained the oil from the york and put in 14 ounces which is what the manual calls for.
After the test I drained the air oil separator and i have a picture of how much came out — 4 ounces
