Friend of mine picked up a Yukon XL at an auction that he discovered was leaking oil from the rear cover at an alarming rate. 15 minutes at idle left a 4 foot wide puddle of oil on the ground. You can see the wet kitty litter still on the ground from cleaning up that discharge.
Dropping a bottle of ATP 205 reduced the oil leak to what you see on top of the cardboard box. That was created post-treatment, after a 15 minute drive, then parking and idling for 20 minutes.
We also parked the truck over one spot out in the street and left it idling for 10 minutes. That time, it left an oil spot about the size of a penny. Little enough that it could be previously discharged oil dripping from the chassis.
Long story short, it worked a miracle. If it weren't for the good reviews of what I considered to be a "gotta be bull" product, I never would have tried it.
