What is the normal temp for the engine oil to run at? Mine runs at about 104C around town dropping to about 102C on a run.
 
As mine Leon Cupra R 2018. This is normal, slightly above 100c so water condensation disappear.
 
If I’m cruising, not driving in Cupra mode or flooring it, it’ll be at about 80-90°C. It increases to high 90s low 100s if spirited driving. Very rarely can be around 110°C

My is up to 140 degrees at summer.
At winter after some short spirited driving is 100 degrees.
Should I be worried about it?
 
Oil temp of 140 c is very high.

I also have100-104 c in mild winter in southern SE. Even in a hot summer day, say 30 c on a "track day" full output, I haven't been near 140 c.

PS Leon Cupra R 310hp 2018 :).

On a track day I run between 73 and 100 BUT i do have an oil cooler fitted.

The oil cooler obviously reduces temps which based on my testing confirmed it can reduce temps by 15 - 20 degrees.
 
On the way to S Wales, 27deg today car was up to 104 after 30 mins, then went to 106 and only when the speed went to 30-40mph the temp was back to 99ish.
This normal?

Probably, due to the warm weather. It's a small blip and then settles back to sub 100. Unlikely to be a big deal.

Having said that, I've just replaced my oil cooler. Car was starting to sit at 105 to 109 on a normal 55mph road and then up to 119 on 80mph drives. Took ages to come back down again. I knew that wasn't right. A few YouTube videos and Google-Fu later and I decided that the oil cooler was probably at fault.

This is for 2 reasons:

1. The actual oil filter housing that bolts to the block is made of VAG plastic/chocolate/brittle bar and is prone to leaking. It's usually the rubber seals that fail and cause an oil leak.

2. The actual oil cooler "radiator" gets bunged up over time, much like the good old heater matrix. Coolant doesn't flow very well and the oil gets too hot.

Although I can replace just the cooler, I decided that due to the amount of work to get to it, I may as well replace the oil filter housing as well. The book says it is a 4 hour job and it took the garage 6.5 hours, just due to the amount of pipework that needed removing. We had a play with the oil cooler and it definitely had resistance and reduced coolant flow when run under a tap. They eventually blew an air line through it and although coolant flowed, It was under a much higher pressure than the coolant usually flows at.

I've only driven the car locally since it was done (£750) but so far so good. Need a longer run to be sure. Just a heads up for anyone else who might have unreasonable high temp issues.
