As was stated, this was made for the Loblaw group in Canada, who run grocery stores under many names. I remember as a kid, my dad was on a shoestring budget, he used their no name oil on his car with no dire consequences. I do remember back then that a store flyer or something stated their oils were made by Imperial Oil (a subsidiary of what's now XOM), and the cases and bottling seemed to confirm it as they otherwise appeared idential to Esso Extra oil. Don't know who their supplier is now (didn't even know they still carried it, I thought it was long dropped from their line), but chances are another major company, if not still XOM. Also, no way to know to what specs they are made to, other than to meet API requirements.
That said, would I use it in my vehicle today? No, unless it was an emergency and I couldn't get anything else. If I had an old car to use it in that is an oil burner or otherwise something I will just be coaxing the last few thousands of miles out of? Sure. (Bought some generic Canadian Tire "Autolab" oil for a 1993 Civic back in 2001 just before I was planning on ditching it). That, or something like a lawnmower.
