Here's mine:

1983 300D turbo, 295,000 miles (prob has more) with last 60K on a custom WVO system of my own design.

Conditions:
1. Air temp 95F
2. Engine hot after driving 40 hwy miles
3. idle rpm= 750

It took 9 min 30 sec to inflate a 40 gal garbage bag to 3/4 full. It was so slow to inflate and I was getting impatient and shut it off before it fully inflated.

Engine runs amazingly well for it's age. Starts easily in the coldest CT winter. Good power, no smoke. Leaks a little at the rear main seal and burns some (I add a quart in approx 3,000 miles)
