Oil temperature low???

[LHM]

Hi guys,

I have a 2011 Scirocco R (standard) and I always like to keep tabs on oil temp etc. I don't do many miles to work (9 miles there) and the oil temp rarely gets above 82 degrees. I have owned the car for appx 5 months now and its always been the same oil temps. I did an oil change appx 4 weeks ago with Castrol Edge 5W 30, the oil temps have been exactly the same as before the oil change.

Today I drove to Stoke (appx 40 miles) and the oil temperature did not go above 85degs and I was doing a steady 60-70mph most of the way. Is this normal?! I was expecting my cars oil to get hotter than this!

On a side note I drove back home from Stoke in a 67 plate VW Polo 1.4 petrol and oil temps went upto 95degs, again doing a steady 60-70mph.

85 is too low on long trips, my coolant is 87 degrees when on temperature. Oil always hotter.

this is my concern, oil temp does seem a tad low. Coolant gauge is always bang on 90 degs when upto temp.

Coolant temp gauge is "corrected" to display 90 degrees over a range (75 to 105 degrees)

I've got a 170 diesel and my oil temp rarely goes below 90 and is normally somewhere between 92 and 102 depending upon engine load.

I would agree your seems a little low.

Your thermostat needs changing.

I had same issue.

I had same issue.

I thought Thermostat measured water temp not oil temp? My water temp gauge is bang on correct and gets upto 90 degs after 5-10 mins of normal driving. I drove from Stoke to Manchester today and my OIL temp went upto a maximum of 87 degs, mixture of M6 driving at 50mph (roadworks) and a few blasts beyond that when off the 50mph limit. Average oil temp stayed at appx 83/84 degs.

Yes, but you have an oil / water heat exchanger to cool the oil.

It's too cool. It should be mid 90s.

Exactly the same issue when my stat was icky.

Change it for a genuine one.

Thanks mate. should this log a fault though? I scan my car with VCDS a few times a week and there are no fault codes?

Read my comment above regarding the coolant gauge being "corrected" to display 90 degrees over a range (75 to 105 degrees). You can measure the actual real-time coolant temperature using VCDS. A stuck open thermostat won't log a fault.

Guys I appreciate all your comments and help. I assume this will be looked at/sorted under my das welt warrenty? I have had the car just over 4 months now (purchased used from VW).


Thanks.

I can't think of a reason why not.

cheers. I will give my local vw dealer a call tommorow to get this looked at. Somthing is not right at all. Just drove hard to and from Manchester and the oil temp did not go above 84 degrees.
