Dependes on where you are taking temp from but the oil should be around or above 80 C to be warm enough to do it\'s job correctly in the engine. Else the car isnt warmed up enough or are cooling to much with open thermostats or something like that. Or temp taken on the far end of the cool side on its way back.
But hard to compare if temp taken at different places .... witch it most often is.
