It's about 20 minutes for the Park Avenue. Most of the time is spent in allowing it to drain. There is the adding of the oil and I usually take the first bottle pretty slow, then, when it's done I leave it in the oil fill and take my knife and cut around the bottom of the oil container (plastic..it's now upside down)on 3 sides, peel it back, latch the cut open piece to the car (as in propped), and use it as a funnel for the rest of the oil containers. Keeps spilling to a minimum, and alway a clean oil fill funnel, as I now just throw away the makeshift funnel with the rest of the containers.
