Not really a "normal" as each car is different, however you want the temp to stay as cool as possible (within reason) and the oil pressure to remain moderate. In other words, ideally the temp gauge would stay from C to the middle and the oil pressure would be middle to H. All this said, these are really just guidelines and do not really provide a good indication of what is really going on, they are there just to tell you when something is wrong and needs to be looked at. I run aftermarket mechanical or electronic gauges in all my cars
