Hello. Last week i added the engine oil temperature to my MDS. Whilst doing this a saw that the temperature was 111 degrees Centigrade of my 1.6 TDI engne. this was under normal driving conditions. Does anybody know the temperature range which is viewed as acceptable?

99°C running on my 190. Never seen it go over 100°C

I noticed the oil temp in our 150 TDI is generally hotter than my Yeti 170 TDI.

In the Superb, when I occasionally check, it's around 100-105ºC.

The Yeti generally sits around 95ºC.

I have a chipped 150. My oil temp is influenced a lot by asphalt temp. During the very hot day on highway with aircon on, I get 125C cruising at 130km/h. During the night with aircon on, 130km/h, same highway, I get 105C.

 

On open roads... around 95-100C.

I second this, the normal op temp for my 150 is 93-105°C. If I set off to the shops at a gentle trot with my economy driving head on, by the time I've covered the 10 miles the car is registering between 93-95°C.

More normal / spirited driving brings with it an increase of 10-15°C so up to a max of 110°C. On the Autobahn I can regularly see 115°+ if I'm sitting at 160kph. On a max effort 126°C was seen, but I always drive like a granny the last 10mins of any trip to get the oil temp under 100°C so as not to cook the oil in certain parts of the engine.

Like the quoted poster mentioned, oil temp is influenced a lot by the road temperature. When it's 34°C out the engine oil runs hotter and there is little you can do about it.

The engine coolant has a huge operating window and large radiator, so its unlikely to go above 90°C unless there is a problem. The oil cooler is tiny in comparison hence struggles more, and as oil is also a coolant to moving parts i think this is important. This is another reason why I will change my oil filter every 5k miles and oil every 10k miles. Filters haven't got better or bigger so the likelyhood of restricted oil flow after 10k (with oil that's been run a little hot) is much increased in my opinion.

When I first had my Superb it regularly got up to 117 degrees on motorways, and that was in winter.

I am now up to 5500 miles and the temperature seems to have settled down so that I rarely see more than 107 degrees even on motorways in hot weather.

Mine usually sits at about 100-105 degrees C. Highest I've seen is 114 degrees C 

My 1.4 TSI petrol, generally sits around 99 to 101 degrees C regardless of AC on or off and outside temp. That's when cruising 70-80 mph. I think when I've occasionally done a bit of spirited B road driving it's gone up to 105 but no more.

My 2.0 TSI generally runs at exactly 104oC once properly warm.

Agree, mine is normally around 103 - 105 degrees.  Driving fully loaded on Friday through Germany at motorway speeds so will be interested to see then.

My 1.4 tsi is around 100 - 105.

Its normal.

Looking randomly throughout the journey it was fluctuating between 105 and 108 (2.0 220TSI)

Highest I've seen my 2.0TDI was 116 degrees, this was when charging up the twisties in the mountains at high altitude.

The Octy 1.6 TDI I seldomly used was as high as 120 degrees.

 

On normal long drives on motorway, the temperature is around 103-105

 

It's ok.

 

What's REALLY IMPORTANT is that after hitting such temperatures to allow the engine to go below 99 degrees before stopping the engine. This allows the turbine to cool off (it's lubricated by engine oil).

I do not know for older models but on the Superb III the cooling continues even after you switch the engine off (you can even hear the sound of the pump continuing its job until the turbo cools down sufficiently).

 

Temperature wise my superb 280 usually runs between 100 and 106. When used for more spirited driving it can go to a little over 110.

My 150PS TDi never went over 104 degrees C in France fully loaded at 130 km/h a couple of weeks ago when outside temps were hitting 32C. I have a factory fitted towbar and I know that the brochure implies that other changes are made around that.

 

FWIW, the car runs at 100 to 102C in Ireland where temps are generally under 20C and the car is mostly empty.

150PS TDI(manual) keep between 105-111 C on a hot day(above 35 deg C) and running with 140km/h(87m/h) on a highway. On open roads and speed ~100km/h (60m/h) temp does not pass 100 deg. When engine is heavy loaded have seen the temp to reach 115 but it drop down fast.
