Why would you be surprised ? Dollar General has become a huge retailer in the US (at least half of everything they sell - just by my observation - is the same name-brand products you would buy elsewhere) and if they're stocking engine oils, that means they sell engine oils. They can have a major oil blender produce for them just like auto parts stores, Walmart, etc.
I bet they will. They don't make this oil.... They buy it from someone that blends oil and that blender is most likely to transition, if they haven't already, to the latest specs and DG will just get it by default. The DG near me sells Mobil 1, Castrol, Valvoline, and more oils. They also sell a few different ATFs, brake fluid, and so on.And I wouldn't think they would move enough oil to have SP so soon.
i picked up a “just in case” quart of dollar tree oil to keep in my yaris emergency kit. does anyone know what it is? i assume that it’s pemex from mexico only because many other perfectly okay dollar tree products are sourced in the lower cost third world.Their sister brand Dollar Tree sells half quarts for a buck. I think it was SN when I looked last week while picking up a drain pan.
