Sure, why not.
Nothing like making a little boom into a big one.

 

Use a gallon of ATF in the oil.

 

Never heard this one before. What's the reasoning for it?

 

Atf is a better cleaner then oil. It just can't take the heat.

Seafoam is another option but much more expensive.

Either can be run in oil or gas or fuel.

Boss man fills up the fuel filters with atf before installing. Cleans the injectors.

I've used it in both gas and oil. Usually can make the car sound and run better. Back in the days of dirty gasoline.

 

One look inside an automatic trans, tells a lot. Clean as a whistle. I doubt he has a sludge problem. If not for it using coolant, Id say a little Lucas to combat the thin oil. He’s got much bigger problems than blow by. Old engine needs an overhaul, before He ends up on a hook.
