Recent trip through WM saw Mobil Super 5000 conventional as lowest price big name oil ($13.xx) 5 qrt jug, followed by Quaker State Advanced Durability ($14.xx) , Pennzoil conventional $16.xx) , MC Syn Blend ($18.xx) Quaker State Ultimate Durability ($20.xx), PP & M1 ($24.xx) and PU / M1 ext ($27.xx) Based on above regular prices Quaker State Ultimate Durability synthetic has a nice price point for performance / price point . If I was a conventional user I would give the Mobil 5000 Super a much closer look versus just reaching for Quaker State Advanced Durability at $12.xx a 5 qrt jug before the price hikes .
