kragen sells used oil drain pans you can bring back to their store and dump the old oil.
I bought 3 and saved my used oil for a year.
When I took them in they told me I could only dump 2 per day.
I said that's ridiculous. You want me to make another trip tomorrow to dump the third?
The guy told me he was doing me a favor by letting me dispose of the old oil. I told him you're not doing me any favors by making me come back tomorrow. I bought 3 containers with the understanding I could fill them with my old oil and dump them here. He continued hand me his line of bs and I told him I would never come back to Kragen.What a bunch of jerks!
