Too cold for driving
Discussion
Some folks have put temperature senders in their filter housings, but I don't think I have seen anyone with a thermostatic bypass valve for the oil cooler - which I would have thought would be better practice? Maybe it's rather complicated to do!
As usual I have some ideas but no skills to implement them...

Neilus has the oil cooler bypass valve and an oil temp gauge in place of the clock. He says it reads very low in the winter (30oC). I have a dual oil temp and oil pressure gauge to go in, in place of the oil pressure and water temp gauge. I'll get an oil cooler bypass valve fitted at the same time and possibly look at a means to reduce the airflow over the sump for the winter too.

I drove to London and back yesterday. Jaysus my feet were cold! I must seal all those holes and gaps up at some point.
Looking out the window at the sun this morning, I walked out the door with all good intentions of taking the cerb again. As soon as the cold hit me I walked straight back in and picked up the keys to the Audi. Ahh, lovely and toastie

16 mile run to work in the morning. I can usually give her a few beans toward the end, but today she was a bit rattily from start to finish.
Beans and rattily makes my hair stand on end
I have an oil temp gauge in place of the clock plus a thermostatic bypass on the oil cooler. A few weeks ago on the motorway the oil temp would stabilise at around 70-75 degrees on the motorway - exactly the same as the coolant temp. In London last weekend, stuck in traffic for ages, highest oil temp was 90 degrees. I'll be keeping an eye on the temps when I drive home this weekend, the thermostat does get the oil up to temp quickly, not far behind the coolant actually! However, I'm sure the oil thermostat opens at 80 degrees, in which case the oil cooler won't have even be doing anything on the motorway, which is a bit strange!!

As SteveT says, I've got a thermostatic bypass fitted for the oil cooler and an oil temp guage.
Last winter the oil temperature would be around 50C if I remember correctly. When you were stuck in traffic it would creep up, but as soon as you started 'making progress' the temp would quickly drop back down again.

I fitted my own thermostatic bypass and tapped into the oil filter housing for a temperature sensor.
The thermostat is the bypass type which you install in the two oil lines running to the cooler. I used the push -on type with some hefty jubilee clips and it was VERY tight pushing it onto the hoses.
Cutting the hoses was also a game as they're metal reinforced and I used a cutting disc in my angle grinder in the end.
I then replaced the crappy std dual pressure and water temp gauge with one from SPA design and bought a second temperature sensor from them both temp sensors were wired in via a switch to allow me to swop the temp signal from water to oil (temp range is the same). The top half of the gauge still reads oil pressure but now with a decent sensor
with the thermostat in place the water temp increases to 75° within 5-8 minutes and the oil temp then takes about a further 15 mins to reach the same temp but this depends hugely on how you're driving.
Just cruising on the motorway will tend to see oil temps of about 65-70° whereas if you start using the revs it'll climb up to 85-90°
One last point is that I welded on a block of material to the top of the filter housing to accomodate the sensor as it was too deep into the flow otherwise.

Drove into work today on what must have been the coldest day of the year so far. Car def runs cooler in this weather and its the one time of the year I wish I had an oil temp gauge.
Does anyone else think of half covering their radiator, or increasing th size of the numberplate etc?

Maybe you could put some press studs around the grill, then put a landrover rad cover on it.

Don't need a rad cover - this time of year after a few miles the leaves do a pretty good job.

I've got an oil temp gauge and it does run very cool in cold weather. I'll probably block off my oil cooler this winter, as the oil is also cooled (indirectly) by the water cooling the engine. Last winter on the motorway the oil temp was barely off the cold stop.
I thought about an oilstat, but then decided against it as,
1. Have to cut the hoses to fit
2. I'm thinking that over the winter you'll end up with the oil not really circulating much at all through the cooler, maybe leading to sludging up?

Yep, my thinking was rather the same. I think I would be happier fitting a shield inside to either cover part of the rad, or something that just restricts air flow around the engine.
Just got back after a 3 hour run up the A1 and it was bloody cold, sub zero now I'd say. The water temp was holding at 67-68 degrees and the oil temp the same. The car was freezing, the heater system does nothing at all making the journey quite uncomfortable. What temp does the water thermostat open anyway, thought it would be higher than 68 degrees as the water temp affects fuelling am I right. I've noticed that it kangeroos a lot on part throttle when its cold, smooths out when warm. Strange.
Drove back from the UK on Weds night. Day started off well but the ice warning light came on after sunset. Car used to be cold until I blocked all the air-con distribution pipes with dusters. Now can set the interior temp to within a few degress just by varying the heater fan. Mmmmmmmmm !
