Even the manual of your car recommended a 5W-50. This oil will take more than stage 3.
Oils are only too "thin" if the hot visco is reduced ..W-20 or ..W-30.
A 0W-40 isn't "thinner" (mostly it is stronger) than a 10W-40, but the cold visco is much better so better protection from cold start (very important) but at hot temp. both are equal, so it's compared to a 5W-50 and 15W-50. A 5W-30 is thinner than a 5W-40.
For me its more important cause I use my cars as a daily and all over 5W- cold visco is too thick for me........ and you know even on hot summer days it is always a cold start for your engine.
