When it was at Dollar Tree stores? I think I've found out why it was being discounted: sealing issues on the cap. Every single bottle I bought there is not airtight, and the oil is leaking out. Even stored right side up, the oil is like migrating out and staining the wall in my garage!
I'll give kudos to Trop Artic: it not only does not drain back and off parts when the engine is off, it could potentially find it's way out of your engine through the oil cap if it isn't on tight!
