enrico, if you get paranoid about the oil cooler the best thing to do is get one
At the track there is a lot of waiting time. When you finally get on the track you will get all excited and tend to forget about oil temp/oil problem. Oil will break down at 160 and cause accelerated engine wear according to a Canadian oil journal. However, the general concnesus is that the cooler the oil temp the better. As most ppl stated that the hotter the oil the less protective etc. I get paranoid with oil temp above 130. My last track day, my oil temp was around the 130 and my car has got a factory oil cooler It was warm on the day though. I would not go to Mallala again until I get a extra oil cooler.
Could you pencil me in for Mallala please?
My car hopefully be ready in around a month
