I believe this stuff is the same oil as the walmart supertech synthetic. The bottles are Identicle and the wording is word for word on the back of the bottles. I would guess they come off the same line, just a different sticker. (10w-30 high-milage synthetic). The HM semi-synth is also the same I do believe. Who makes it I do not know. The meijer dino oil is made by citgo, states it on the bottle.
