Oil operating temperature and oil cooling
I have read in several threads that the oil temperature which is shown trough the OBD 2 port, being measured at the sandwich plate, is in fact 5 to 10° hotter than the actual temperature in all the engine and / or at the sump.
Does anybody know more about this? is it true / false / in between?
That could generate an issue because, after installing an hks oil cooler with a thermostatic sandwich plate set to 80°C, now the oil temp (which I read trough the OBD) is alwyas around 79 -- 82° C during normal road driving or highway..
If the above story is true it means than that the oil never reaches operating temp? could this create some issues?
I often track my car but i would not want to go around doing "normal" driving and damage the engine because it runs 70% of the time at a sub optimal oil temp. Also keep in mind that now ambient is 30°.
during winter i was going to cover the radiator...but i am having doubts that I might have to do it already.
any opinions?
