I was in the local 7-11 convenience store and was surprised to see that they had their own brand engine oil in several grades, along with PSF and ATF and probably some other fluids. The oils were SN rated, but I didn't look on the bottom of the bottle for any telltale markings. There was no price listed for any of these fluids (unless I'm blind). Anybody know who makes this oil? Of course unless it's dirt cheap I'd probably avoid it.
