For GDI engines most knowledgeable oil enthusiasts here agree that Valvoline Advanced 5W30 synthetic oil is a great choice due to make up and especially very low VII's helpful to reduce IVD in GDI engines ... The lone negative I could find is that SA was on the high side as compared to other synthetic 5W30 oils as higher SA content can be a negative for GDI engines (i.e. leading to increased IVD ) . *Does anyone know if the new SP formulation has lower SA content (going off of memory I believe the 5W30 Advanced SN Plus version was 0.97% SA , but I could be wrong) . If SA levels has been reduced in Valvoline Advanced - then a truly great synthetic oil could have possibly become even better !
