will more or less fluid come out if it is parked facing uphill? What about downhill? What about jacking-up one side?
Same question for motor oil?
Thanks

I would suggest that the risk would outweigh the reward of minimal extra fluid draining on an incline.

I've got a slight slope in my driveway, so it's a matter of heading up or heading down for me. Flat is not an option.

Heading downhill helps ATF drain better.

Heading uphill drains oil better.

*** No need to jack the car in either case. ***

The oil drain seems symmetric, so jacking one side will probably not help.

The ATF drain can be helped by jacking one side - I forget which, but you'll see when you get there (jack the driver's side, I'll guess).
