Oil temperature too high...

[-pseudonymous-]

Alrite lads...

On my way to the petrol station tonight i noticed my oil temperature gauge reading around 120 degrees. Normally it reads around 95 degrees when warmed up and never over 100 when driven hard. Does anybody have any idea why im getting such excessive readings all of a sudden?

Before anyone puts it down to my eratic driving, thats not the case for once cos i was driving sensibly off boost.

changed the oil of late?

or the lack of oil? Less oil should warm it up quicker...

Yeah i had an oil change a couple of months ago. Will check the oil level tomorrow. Cheers for the suggestions...

What gauge is it? Make and wheres the sensor?

Its an autogauge mate and the sender is in the oil pump housing...

Just wanted to bump this up as after alot of searching the general consensus is 'normal' oil temps for road use are ~90-100. After sorting all my issues with the oil temp guage and sender i went out last night and the readings were within this range (mixed driving boost/town/country road/dual carriageway). The highest i saw was ~105-110 after a fair bit of hard low down pulls.

However today on my way into uni the oil temp was sitting at almost 120 after a very short blat (0.25 miles) up a dual carriageway then very slow in traffic until i got to the car park.

It may just be me being paranoid but this is with brand new Synta Gold running through it and a new oil filter aswell

Should i just stop worrying and get on with it or could there be something wrong?

Is your oil temperature always reading this high or was it just on this occasion? Is the temperature dropping agen when driven causiously? I dont think your oil temperature should really ever reach anywhere near 120 degrees on the road provided you have good quality oil which is changed regularly.

My problem was down to my water pump failing. May well be the case with you too. Are your fans kicking in at around 90 degrees?

No the water pump is also only around 3k old, that went right after i got the car

Water temp never deviates from 90 once the car is up to temp.

It may have had something to do with te roast the car got then having to sit in traffic for 15mins to travel ~1.5miles

The oil thats in there now is only, at a max, around 50miles old along with the filter and i plan to/do change it every 4-6k miles. Ive actually done 4 oil changes since ive had the car and ive had it for roughly 6k miles at a push

On the way home from uni (6 miles of country b-road) the temp never got above 95 (from a warm start as the car only sat for just over an hour) so the standard oil cooler is obv doing its job. Will go for a drive tonight and see what it does and report back.

Right managed to get a pic of the guage showing the high temp.

This is after doing 50-60 (off boost) for 5 miles then around 20 mins in traffic at a snails pace for another 1.5 miles!

Is this normal or not?

According to a vw tech on my local forum his mk2 golf 16v's run that high all the time

tbh i'd be thinking of trying a different gauge and sender to prove it.

i've had a couple of them autogauge gauge's on previous cars and found them to be crap and unaccurate.

i am a calibration engineer specialising and temperature and pressure calibration so i have the means to test such things.

 

[Pidge]

The setup i have just now is a RevoTech sender hooked up to the autoguage guage.

Long story short: The original AG sender was too long and cracked off inside the oil filter housing

Thats why the car had its second oil change in 500 miles and a new filter

Ill see if i can get hold of another guage to check but i might struggle. I do have the Cupra R VDO guages at home though. Is there a way i could hook that up to the sender and check it through that?

 

[wilz]

Wire up the proper ones like my ones pidge, stop the messing about.

 

[Pidge]

Bit harder than that Will

The Cupra R gauges have a specific connector on the back of them and i cant seem to split it open to get access to the innards and see if there are normal spades behind them

Any ideas how to open up the back of a Seat VDO gauge anyone?
