hi, i got a 1999 turbo 2000

standard its 215bhp and this has been remapped, exhaust, 440cc injectors, filters and is now on 280bhp (wrx speed)

just wondering if i should get an oil cooler now? or could i leave it for later and buy something else?

I'd say you would only need to fit one if you were going to do alot of track days with the car. where the car would be driven very hard.

I'm sure someone will put me right if im wrong

what he said..

For every day/fast road they only serve to increase warm up times and complicate oil changes..

Monitor oil temps and this become obvious..

There is a water-oil cooler/warmer as standard that's quite effective for 'normal' use..

Would it not be sensible to buy an oil temp gauge for under £40.00 and find out if you actually need a cooler.

My opinion varies on oil coolers, but surely with a thermostat on there to only open it up to the cooler at a certain temperature would sort the warming up process? Plus an oil cooler, with a nice big PC fan on it certainly would make traffic temps lower

True, however, unless I'm mistaken they still need to be drained independently at oil change if you don't want 1/2 - 1ltr of old oil left in the system..!

Don't fit things you don't need, it only adds unnecessary weight, which = less performance. If you're really undecided fit a temp gauge first, as said..!

Jason mate, you're worried so much about weight haha
My dad has one on his, and finds no problems with changing the oil. I've seen 110c on my Defi's before when caning it on a warm day through some back roads. I think that's rather high, but then again I don't know if that high warrents a cooler.

I would say not, and as above, fit a gauge first or you'll never really know!

Why not contact your oilsupplier tech. dept. I dont know of any synthetic or semi synthetic that cannot handle 125 to140centigrade.

unlessit is track car with considerably more power than standard itis odds on you will be wasting money on cooler but it is only £40 to know for sure.

ZEN Performance

140ºC in a subaru engine? ouch, engine rebuild here we come.

Mew

for when i do get an oil gauge... wot temp is engine supposed to be then??

p1dazza

good oil will be safe not over 125centigrade but tech deptment for the oil you choose cantell you this info. Might be much more than 125 andclassics have oil tmp about the same as water around 86.

GazTheHat

I've not seen my oil temp on the defi's over 95-98 degrees.

Take it that's good then.

85-87 on normal driving.

Tidgy

personally i wouldn't push a uk car over 105 degrees before backing off and letting it cool down, but i have had figures of 115 for absolute max, 120 is a bit risk, 125 is prob gonna be bad, 130 is def a no no and you'll neeed a rebuild unless your very very lucky

i had a oil temp gauge fitted to my scoob and was amazed at the temps and how quickly it was hitting them, on hot days in the summer.

i went down the route of an oil cooler.

unless you do the oil changes yourself y worry about it making it a bit more of a pain lol

thinkt he best route is, as sugested, get a gauge fitted and find out what its doing.

T what's the procedure for oil change with a cooler, do you have to remove a hose..?

Tidgy

not sure lol

WhiteNoise

I have an oil cooler fitted to my version 3 sti ra and at this time of year the oil temp does not rise to much above 74 deg c,only when sitting still,then only goes up to about 82 deg c.
Saying this tho i have defi gauges fitted and i am not sure where it is takeing the reading from!
Belive that the hottest point is above piston number three.

p1dazza

Low oil temp, probably below 80 centigrade running temp is probably a cause of early wear.
If a manufacturer says his oil is good to 140 centigrade and several do I think it is beeter to rely on their advice than that of the people who think they know more about oiltemperatures than the oil manufacturer. You could put a 20 centigrade margin on for a dodgy guage or failure to notice it in time.
What I know for sure is safe oil temperature is along way past 105 and I am sure lots of Subarus have had oil coolers fitted needlessly when the money could haved gone to more beneficial mods.

Can comfirm oil temp in my 03 WRX of 100 to 110 easily when driven hard.
Normal driving gets me 90's, around 96 i would say on me Defi. Then cool to me is 90 if doing my Notts. 40 mph ring road run! LOL.
I have never had mine hit 110 or above, BUT i have never been on track, which if i did i bet it would reach 115 or more.
In my very basic knowledge, leave the oil coolers to the track monsters.

I've noticed that New Age cars tend to run higher oil temps than Classics.
I have also seen over 125C on track on the hottest day of the summer but was driving at 10/10ths for continuous laps. No engine issues but I pitted each time 125 C was exceeded and let it cool slowly.
I have noticed on VW and Audi cars fitted with oil temperature guages that the red line is at 140C and on a Porche 911 I had sometime ago I am sure the oil temp was OK to 140C.

instead of an oil cooler, you could just relocate the filter, mine is now sat behind my drivers headlight in the engine bay,makes oil/filter changes so much easier too.

my temps, even when raggin it in the summer only hit 98 degrees C.

easy to fit too
