I just bought a new 2015 Mazda 6 with skyactive technology and I am looking for a recommendation for a good syn oil for it. The stock oil is syn with Molly in it but I would like your opinions on something I could buy at Pepboys or Nappa.. Thanks
If not mistaken, Mazda recommends 0w20. You would be hard pressed to find a poor 0w20 oil. If moly is important to you, go with a SOPUS oil: Quaker State Ultimate Durability, Pennzoil Platinum. If not, Mobil1 and EDGE have some moly as well. But even Valvoline Synpower would be excellent with its Sodium based addv pkg. They, and others, would suit your needs quite nicely and can be found at the establishments you mentioned.
