I will still double-check using the dipstick afterwards to make sure. Last time I did the drain & refill on my tranny, I didn't have to add anything. It was nice getting to the correct fill level in a single iteration.
For oil changes, I just like the fact that it has high sides and the container's mouth ends up being really close to the drain bolt when the car is up on ramps. My Subaru has such a large drain bolt that the oil tends to gush out at a fairly high velocity. With this "pan" I find it easier to keep the splashing contained. (No, I haven't install a Fumoto valve yet.)
