You could probably actually sell all the stuff in the round cans on ebay, for more than it is worth. The ATF would be good for homemade penetrating oil and soaking things that need to be soaked in oil.
What is the "Nitro", anyway? Oil additive, or fuel additive?
The 30 wt would absolutely be going in a lawn mower, especially the Rotella. I have enough older vehicles that could use the Dexron II. I also have a leaky floor jack. You can never have enough hand cleaner and shop rags. Nothing wasted here, but not sure what to do with the Nitro 9... chain saw maybe?
