Hello, in order to be careful with my ageing engine (Impreza STI 2.0) what are the recommended temperatures for oil and coolant at:

Normal driving:

Track:

Temps you should not reach because something is gonna break:

Please no guess but some solid answers are appreciated...

thanks!

(Sorry if this is a recurrent topic...)

With my STi the PSi3 meter regularly shows 96-97c water temp. in day to day driving (the temp. at which the fan cuts in.) Oil temp. is often 90-100c but this is dependant on where the sender is located.
On track I've seen 120c oil temp. at which point I came in to let things cool. This figure is not a problem if you're using a good quality synthetic.

After fitting an oil cooler mine runs at around 82-86 degrees on track.

Don't want to have to worry about it !

P.S. std. water gauge, has never moved from it's "normal" position.

Dunx, do you find that your oil takes a lot longer to reach normal operating temps with your cooler fitted? Just wondering as a FMIC is on my to-do list for next year, and I like the look of your top mount oil cooler

That's, literally... well cool.

At what figure though, are oil temps considered TOO LOW?!!!

On track, without any oil coolers and none wrapped headers, i managed to get the oil temp up to 135 where i sharp slowed down and went in the pits for it to cool...

Now ive fitted an oil cooler and wrapped the headers, i get 100 max (depending what track it is)

Anything at 120+ you should really slow down... but i would reccomend an oil cooler for track.

thank you!
