While the heavier 5W30 synthetics (M1 , Edge ) have their place - the PP 5W30 D1 / Gen 2 with a cST of 9.6 @ 100 C. and A1/ A5 rating (plus GM , Ford , Chrysler and Honda ratings ) is just about ideal for this engine . It's a light 30 weight for a bit more ideal for faster warm up , a little a more free / less oil drag running engine and the A1 / A5 rating should help the oil from diluting out of grade with a GDI engine (still with an HTS of 3.0) ...I toyed with the idea of trying the PP 5W20 but just too many great things with this oil not to use it again (Georgia , USA winter fill) and the roll back price at WM was $22.88 . Lastly , this is the only oil and grade I have used of the name brand 5W30 synthetics where the engine is so quiet all you hear is the faint sound of fuel injectors working or you wouldn't know the engine was even running . Just say'n those with Hyundai / Kia 2/4L GDI engines give the PP5W30 oil a try and I believe you will be happy with the results (5K Mile / 5 month OCI Fram Ultra #9688) .
