I had huge problems trying to get my oil hot enough, even with the cooler unplumbed, the oil was still too cool for full protection.
I put in a 90 degree one last weekend, and the oil temp's now floating about the 80 degree marker (as opposed to the 50 degree marker) which is much better. It also sounds and feels much healthier.
I'll maybe put it in for track days, but not for general driving.
The reason I bought the stat was as an attempt to reduce oil temperature. I should get a temp gauge on it, but as it is at the moment I am suspecting that it is a bit too high.
John, you're car gets much hotter as it's a turbo (read small (hopefully) controlled bonfire under the bonnet), so the heat problems'll be more pronounced with you lot.
Mike, you'll need to fit a sensor to the sump, Gary's done it, and if we're really nice to him, maybe he'll take a pic .

Under full boost, yes.
Under medium boost, maybe.
During normal city driving (off boost most of time, occasionally some boost) it's basically a low-compression XE with mild timing.
These mornings it takes about 20mins of no-boost driving to bring the water temp up to 90C. Oil is even slower to warm up...
dvandrews was talking about a heat exchanger instead of an oil cooler. I think vw golfs use this setup as standard. keeps both oil and water the same temp, also if the coolant gets hot it will wrm the oil quicker vice versa.
quote from vauxweb user:
According to Vauxhall, this [part failure] is fairly common on 2.5 V6 engines that have done 70-90k. The heat exchanger sits in coolant in the block between the 2 cylinder heads, with 2 engine oil pipes going into and out of it.
The oil flow through the turbo bearing isn't substantial, not enough to make any difference in the sump. Drop in the ocean.
Plus of course the turbo bearing isn't that hot anyway because everything is still cold, the coolant is cold, the metals are just warming up, and you're not boosting ofcourse!...
(We're talking coolant temp 70-80C after a cold start)
Off-boost, the exhaust gases aren't as hot as the XE's, because the compression ratio is low
And yeah, a good synthetic (changed often) will always be superior in stop/start conditions, as well as full boost.
In an ideal world, you'd have a summer setting for the fan swich, the thermostat, the coolant strength etc.
In reality we compromise, don't we?
John you mention a 'cool stat' - but what temp is yours ? - is it the 'courtenay' one of about 80 degrees - alledgedly the one from SA ? - I'd also like one which is between the two extremes.

I think standard is about 92 degrees ? - where did you get yours from ?
well apart from the idea of an adjustable fan controller as per that other thread I don't know tbh - I got into the habit of knocking on the fan manually whenever the temps started creeping up.
yeah - you're right I remember now it is the stat they drop into SA cars etc.
part number anyone ?
