With the V50 diesel, I could hear the difference between 0W30 and 5W30 oil after a cold start in winter, and see it in the fuel consumption.
In Alberta, it's cold enough to see that.
Your auto tranny may well be masking a lot of these effects.
Better not to run Xw20 oils unless the engine is designed for them.
