For quite some time I was paying $17.97 on roll back at WM ... Regular price is $19 . QSUD is fine to run with say a 5K mile OCI ... *For GDI engines I now believe the best oil attributes (for the price) are now with Valvoline Advance Synthetic in 0W20 , 5W20 and 5W30 (as long as they don't change the recipe) . I pay between $21 and $23 at WM for it and it will exclusively go into my 2017 Sonata 2.4L GDI now .
