I use it as bar & chain oil but that is alot of chainsawing for one fluid change. The auto parts stores take used oil as long as it is clean. I just bring it in the containers and leave it at the counter.

They limit you because they do not have unlimited storage space, not because they have to pay to dispose of it.

A guy I know runs a self service boat yard. The yard provides a waste oil tank for the convenience of its customers. They do sell the waste oil, but the company that buys it dings them hard if some jerk dumps antifreeze or any other form or contaminant in there.
Since they can't watch everyone all the time, they frequently get dinged. If they had a real choice, they would get out of the waste oil business, but they can't because their customers depend on that tank being there.
My point -- Just because a business takes waste oil doesn't always mean they are making money from it. There are expenses involved, and it may even run at a loss. Some states require stores that sell oil to collect old oil. They have no choice.
I know a fellow that owns a auto repair shop. He takes in regular oil only. no synthetic. He uses the oil to run his heater for the garage. The model of burner he has will not burn synthetic. I used to take all my oil there, but now that I'm using syn, can't do that anymore.
Since he doesn't sell oil retail, I guess he can be particular.

My local Advanced Auto Parts (maybe this is true across all AAP stores) used to have their used oil tanks open all the time. Then they had to go to only having them open when the store was open. Finally, they had to keep them locked all the time. They also had to implement a sheet that lists the date and time, your name and what you dumped in the tank. They don't require to see id or test what you're dumping, but that's probably next.
People abused the service and they had to add more and more restrictions. I highly doubt they're making money on this. They're probably happy if they break even.
