Strongly considering to run 10W30 synthetic in my May - Oct. oil fill in Hyundai 2.4l GDI (Sonata) : WM has M1 10W30 vanilla and EP available along with Quaker State 10W30 Synthetic , Super Tech 10W30 synthetic and Pennzoil Platinum 10W30 is available (WM online) ... *There also plenty of 10W30 synthetic High Mileage oils available at WM ( which I don't need) . All are now SP / GF6A rated , all would have low NOACK , low SA and low VII's important for GDI engines not forming intake valve deposits . *Not sure how much better the 5W30 D1 / Gen 2 SP / GF6A rated oils are than their above listed 10W30 synthetic variety oils - but you would have to think they would be pretty close in quality ? Lastly , for the warm weather 6 month / 5,000 mile OCI - I am leaning towards using the M1 10W30 EP ($24) and for $18 the Quaker State 10W30 Synthetic is tempting . The Super Tech 10W30 synthetic is only $15 for a 5 qrt. jug but not sure it's key specs. for a warm weather 6 month / 5,000 mile OCI in a GDI engine would be as good as M1 10W30 EP or the Quaker State 10W30 synthetic ... What would be your choice to run ?
P.S. If WM offered Valvoline 10W30 Advance Synthetic SP / GF6A synthetic oil in a 5 qrt. jug - then I would jump on that ! ... Unfortunately WM only offers Valvoline Advance 10W30 in the High Mileage version .
