Mine will be driven in a few says time, does that count? LOL

As for that Mocal item pictured, I would feel safer with an oil to air cooler rather than oil to water to be honest. Yes

Yeah I don't even like the oil to water takeoff that comes on the car as standard anyway, it just seems like an unnecessary point at which both oil and water can mix in case of a failure of a part.

I may just sit in my car now and turn the steering wheel for five minutes to pretend I have been driving it LOL

Mine's been mainly on axle stands for over a year and I've only driven it about 300 miles in the last 12 months, and less than 4000 miles in the last 2 years. In fact I got it 2 years ago yesterday.

Oh and mine doesn't even have an oil cooler so why am I even adding to this thread?

Oil to water is a far safer bet than oil to air. Get a stone through the rad and hole the oil/air cooler and unless you spot the pressure dropping your engine will be destroyed before you know it. Oil to water coolers are bullet proof and can be mounted virtually anywhere in the engine bay as they have no need to be in airflow. However, you do need a more efficient/bigger rad for them to work properly.

Yes, I see what you're saying however I suppose what I was referring to was the lower temps of oil which could be achieved with an oil to air cooler. Yes

With the coolant generally getting up to around 95c on track, that means that the oil wouldn't be able to run at any less than 95c as that is the temp of the coolant which is supposedly 'cooling' it.

With oil to air, I can keep my oil anywhere between 80c and 90c on track which makes a big difference. Yes

Coolant temps of 75 are what you are looking to achieve, get the right rad and you get the cooling you need with no possibility of over cooling when you don't want it.

Yeah true, a different rad on our cars would be what was required, a standard rad doesn't cut it for that kind of temp on the track. However, there is a direct correlation between oil temps and coolant temps, and I find that if I can keep the oil temps at 85c then the coolant won't increase above 90c, before I had the 19 row cooler my 13 row would keep the oil around 110c and the coolant would raise over the 100c if on track for more than a couple of laps so I had no real choice but go for the bigger cooler.

Owain,

Just to clarify the situation, I drove my car on Saturday at an ambient temperature of around 2c, along a motorway doing 70mph.

My oil still rose up to the normal temperature it always does of 80c, and stayed there without me needing to block my 19 row oil cooler with anything. Yes

Therefore, I concur, yours definitely needs a new thermostatic plate mate. Thumbs up

The white line before the "90" is regarded as 80 if you look at the distances set out on the rest of the gauge, you can work it out from this. Yes

Pretty sure its 65Yes

The mark half way between 90 and 140 is the same distance that the line you think is 80 is below 90Dunno

So 90 minus 25 is 65Whistle
