I am dumb. Need opinion.

I would suppose if it is not going to react poorly, it would probably be a better lubricant than MMO or seafoam.
Nothing bad will happen. I spent 23 years working at an equipment rental company and I can tell you as a fact the only really bad thing that you can do to an engine is run it with out a proper airfilter. We experimented with various oils in auto transmissions, in engines,and hydraulic systems etc. and the big thing that killed engines was no air cleaning. Dirt is the enemy! I keep my service van running till the boss made me turn it in for another one by thickening the oil with 90 wt gear oil to quiet down the knocking. I charged off the 90 wt to the rental dept because STP would't pass the rental dept managers ok.
 
The only fluid you don't want to pour into any engine is brake fluid (and coolant, washer fluids and gasoline), actually no brake fluid in/on any part of any car except in the brake system (and clutch for manual transmission).
 
All right, thanks all!
I think what I'm going to do is change the filter a few times during the OCI. That way I will be removing some oil/atf and replacing with good oil over the OCI, and also if there is anything that is coming out of the engine en masse, It will be in two or three filters. When I had realized what I had done, I took the new filter back off the engine and put the one from the last OCI on before I started the engine to move the truck (didnt want to contaminate!). I figure I can run that for a week on the old filter, then put on a new filter to run for half of the OCI, then add yet another filter later (a la auto RX). So thats roughly 2 quarts that will be drained and refilled over the OCI diluting the ATF, and the ATF should be cleaning during that time, or at the very least not hurting anything. I feel better now.
 
You'll be fine, El_Schaf!

This is why I keep my oil and AT fluid on 2 separate shelves, on opposite ends. I've come close to doing the same thing, but usually when people are around to talk to. It's pretty easy to lose focus.
 
I wouldn't worry about it.

Folks add 1/2-1 quart of MMO, Rislone, Wynn's to engines all the time - they're all thin, 20-weigh oils similar to ATF.

Just run your normal OCI.......
