Why 0w40 when 0w20 in previous change? My Caravan is quiet at 100 degree days with city driving as well as over 70 mph drive to New Orleans then stop and go and quick acceleration on interstate.
I honestly just wanted to try something different, I don't have a real reason other than they both get driven pretty hard. I will say, the 0w40 seemingly has quieted down both engines compared to the 0w20 and 5w20.
