What is an ideal temp for your oil to be running at on your scoob?

Or more to the point, at what temp would it be starting to get a little too warm?

Cheers

on my car no matter how i drive it the oil temp does not go above 90 degrees.

all oil is different for retaining its lubricating qualities at temperature,if you post up what oil you use then maybe someone like oilman can tell you at what temp it loses its ability to lubricate properly.failing that try googling it

stiscooby

Thanks.

I haven't got a scoob yet, just looking to buy one. One car I went to look at had defi gages in it and once warmed up temp was nats ***** under 100.

Dunno who told him but he has also had the undertray removed as he was told this would help with oil temps, not sure if thats correct or not? Car has had some mods, running just over 340bhp.

No idea what oil was in it though?

110 plus would make me fit an oil cooler, however...

Just fitted my Defi oil temp. gauge, so will need a proper run out LOL

Depending upon the oil visosity/type used I wouldn't be concerned with up to 130C on track. Normally I see 95C-115C using /50 or /60 oil.

All depends where he has the sensor fitted.

I have Smiths gauges in mine and it's always around the 50 to 60 degrees mark thne goes up to 80 when giving it some stick.

I wouldn't have thought my gauges were accurate at all showing those temps!

I run Millers CFS 10w/60.

Mines in the block near the turbo (NO.3 ?) Defi gauge, normal running is 80-90 degrees but I haven't had chance to stretch her legs 'cos of work...

thats where mine is above number 3 max temp is 90 no matter what speed i do,also running with under tray off so that could be keeping temps down

although due oil change soon so it gets to the 90 mark a lot quicker at present.

The undertray removal made no difference to my temps but the gear box cover that I left on was removed forcibly at 140mph

Tidgy

hope that was on a private road at 140 floyd lol

if your seeing nearly 100 dgrees now then come summer time your gonna have temp issues, mine was the same.

now got a nice shiney, well was shiney when new, oil cooler, made a huge difference. iirc Scooby Clinic | The UK's Largest Independent Subaru Specialists | 01246 590 807 - Chesterfield S42 6QX charge £450 + the dreaded, supplied and fitted.

just make sure its thermostaticly controlled

Eeek, I'm not sure 130 is good mate; I seem to recall a thread from one of the big names on here saying that you were in danger of engine damage at those temps!!!

I'd have a word with the experts to make sure you don't need an oil cooler!

Mine stays at around 90 normal road driving.

Hits about 90-95 when giving it a good blast on Catrol 10w60. That was recently in warm weather aswell.

around 90 ish normal driving, getting near 100 when giving it some neans, using defi gauges, sensor above No 3 cylender, also with fmic

Mine sits around the 90ish mark. Before the last oil change it could get up to nearly 95 on a good thrash.

Mine's around 90 when driven normally, not sure what it is when giving it some, but i was told by and ex-prodrive WRC mechanic that anything up to 130 (when being given serious abuse, track etc) shouldn't be a problem with a good quality oil such as Castrol Edge.

ex-webby

They way I look at it......

Oil temp will have an affect on oil pressure. i.e the hotter the oil the thinner it gets, which can have an effect on pressure. Low pressure is bad.

On my Spec C with the standard engine, running 380bhp, oil temp would normally sit around 85degs on normal cruising, moving up to 90ish with hard road driving. On track it would keep increasing with continued use. I had this up to about 120 on track as my maximum, at which point I would come back in, cool down and go back out. As long as oil pressure is fine, at this level with my set-up, it would just require me to change the oil more often. The Spec C does have a proper oil cooler though.

Since the 500+ 2.5 engine has gone in, oil temps have increased, but this is partly down to the fact that 2.5's run hotter, I am running a lot more power and the oil cooler is still roughly in the same place but with the addition of a FMIC in front of it now. Oil temps are now 90ish on cruise, 95-100 for hard road driving. Track use, again the temp will keep rising but again I will do cool down laps when it reaches 115-120. All in all, not much has changed for me.... common sense prevails regarding oil temps and what you do.

If I was running over 100 for normal road use, I would be inclined to do something about it personally, but in essence as long as the pressure is fine and you use decent oil and change a bit more often I can not see you having any problems.

Another point worth making is that oil temp changes depends on where you are reading it from.

This is a general view and does not allow for high (130+) oil temps. Even if pressure was ok at this level, I can't see it doing much good to the oil state itself under pro-longed periods.

Tidgy

130 degrees is a big big no no, didn't zens car need rebuilding when it hit 130degree engine temps, and that a hugly uprated engine.

I think you're referring to the post I was referring to Tidgy.

Also, I wouldn't regard Castrol Edge as a premium quality oil. Would need to be an Ester based fully synth like Silkolene Pro S to be acceptable with me on a modified car.

Ns04

Tidgy

yup agree on both counts lol

Floyd

iTrader: (9)

A good quality oil that is designed to run up to and above 130C should be OK on track. As said my temps have peaked in the middle of summer on the Ring but normally it's 100-115C on track

ex-webby

Floyd is correct!

You need to look at what sae value oil you are using to determine what temps the oil will still retain it's lubricating properties. Without knowing or referring to this, the statement that x deg's is too high is out of the window (all things being equal and to a certain level).

A 40 oil (fully synthetic) should be ok for up to 120degs.
A 50 oil (fully synthetic) should be ok for up to 140degs.

I personally use a 10w 50 fully synthetic oil in my car.

Tidgy

didn't think it was the oil itself that was the issue?

dunx

iTrader: (3)

Got mine out to Elvington.... and maximum I reached was 104 degrees, at steady state approaching double the legal limit.
But it didn't drop significantly when I slowed down, Hmmmm ! ! ( )

DunxC

P.S. Driftworks have a sensibly priced cooler on their web-site. Next month !

LOL

ex-webby

Straight line run's seem to provide better cooling than on and off track work. When I was testing last month, I was passing 160mph with oil temps not much above your 104degs. Get my car on track and I am sure I could get the Defi off the gauge, and without getting anywhere near 160mph.

New_scooby_04

iTrader: (4)

Me too, and NOT Castrol Edge!!

Ns04

PS I think there was a bit more too it than just oil temps in Zen's example, but I'm sure Paul said that 130 temps were a no, no!

I wish I could find that damn thread!!

stiscooby

When I had my STI Type R a few years back I use to use Castrol RS 10w60 in it, never had any probs. What kind of temps would be ok with this oil?

Cheers

I got stuck in London traffic last night and I saw it rise as high as 97 degrees, but straight back down to 95 after I got a clear run.

I use Silkolene fully synth 10w-40, and it is due an oil change, it's been a 11 months and 1500 miles since the last one.

wrx450

Sorry to take slightly off course, but what is considered to be normal oil pressures. 2.2l stroker - I see about 100psi on start up, It drops off from there as it warms up, and at the end of a hillclimb run it is sitting about 40psi at idle. The hot pressure seems low. I have another new oil pressure gauge sitting in the cupboard and am thinking of trying this just to be sure, Temps at the end run with oil cooler only get up to 95. Use Milers 10w60.

The other 2.5l I have starts at 90 psi and once warmed up fluctuates between 50-60 psi at idle.

JonMc

iTrader: (51)

My 2.0l is off the gauge (max 110psi) on cold start, settles at about 95-100psi when warm and driving. Settles to just over 35psi at warm idle. When I fiited the gauges I searched for the answer to your questions and this seemed to be about the norm.
