Many of us noticed cooler oil temps when we switched to German Castrol(G.C.) 0w40 oil. I used to run Mobil-1 European blend 0w40 LL1 oil, but then I switched to German Castrol in 0w40. I noticed right a way that the engine sounded less metallic on cold starts and seemed to run smoother. Also the oil temps went down almost two needle widths! I was sold on G.C.
