QSUD and QS full synthetic have been my go to oil for my Mazdas for years. QS 0W20 has disappeared from our shelves at Walmart and local auto parts stores. You can't order it from Walmart either. I like and use it for it's healthy dose of moly and reasonable price. I now need to find a hopefully similar alternative. I understand that Valvoline Advanced Syn. has extra moly content but 0W20 is getting hard to find as well and it's price has gone up significantly (along with everything else). Are there any other readily available (and priced) 0W20 weight oils with a good dose of moly out there? Thanks
