I have never quite got this, unless the oil cooler is for something else.
I also wait about 10 mins for the engine to warm up before going to 4krpm and Willay mentioned at the weekend the his oil temp gauge was good so he could give the engine an honest thrashing 
Anyway, if warm/hot oil is good, why would you want an oil cooler?

Too hot and the oil would go too thin to work efficiently.

Oil can get too hot as well as too cool

On the normal road, most people won't rev about 3000-4000rpm.
On track, your driving wrong if it drops below 4000rpm
Engine is being run at higher revs all the time, hence coolent, oil temp and pressure will go up. Adding an oil coooler means you can use the engine harder without worrying that the oil temp and pressure isn't going to lead to a global meltdown in your engine.

Even better answer.
You have to rev to 4krpm in a 12v to get anywhere, and 80mph overtaking on a private motorway is 4krpm.

Cooler is controlled by it's own thermostat in the sandwich plate too.
Only gets used when it is needed.

And if you have a turbo your engine oil is getting pumped through it. Poor oil....turbos are HOT

Oil breaks down or shears at high temps - Depends on oil spec as to what temp this happens.
Well worth having if its a track car tho but can be overkill on a road car unless its a massive spec and runs hotter than standard.

In short Deano, your 1.0 12v doesn't require a oil cooler

No, I knew that. And wasn't even contemplating one.
I just thought you had to wait till the engine was hot till you 'ragged it' so couldn't get my head round the need for an oil cooler as it defeats the object. But now I know

Yeah, your right there matey, never drive your car hard from cold! Oil has an optimum operating temp - Basically where it works best. Too cold and it doesnt protect properly and the same goes when it gets too hot!

Oh and as a "general rule" (obviously depends on outside temp, the car, the driving style etc) your oil takes roughly twice as long as your water to get to working temp (cos I know most standard cars dont show oil temp) So if it takes 5 mins for your cars water temp to reach 90, it will take roughly 10 mins for your oil to get there.

Oil cooler on a 2.0 16v conversion is advised. I've still got my astra one not fitted and it ran hot. Another reason i stopped using it. I wanted a mocal one but couldn't afford the other required parts (sandwhich plate etc). It'll get fitted before its on the road again.
Its a MUST with LET conversions.
AS stu says, oil takes longer to warm, so even though your water temps jsut got up to normal level, don't thrash the engine just yet

 ! I didn't know that 
The trouble is, I live about a 3 minute drive from the A1 and sitting at 70mph my car is revving at 3.5krpm

use 5w30 instead then...this will heat up quicker

I wouldn't be going 7 minutes out my way to let the car warm up enough to go on the motorway.
It will make absolutely no difference at all except waste an extra wee bit of fuel and 7 minutes.

would it make a big difference if the oil is not at optimum temperature then?

I always wait for my temp gauge to get to just above 90 before it goes past 3k. First few gear changes are 2k.
So if my temp gauge is at 90 this doesnt necessarily mean the oil is warm yet?

no, that means your water is up to operating temp

On your average road car (a Corsa, for example) it matters not if the oil temp isn't hot before sitting on the motorway at 3.5k, so don't worry Dean

And to be honest, you're not likely to have the 12v long enough for any engine damage to appear (unless you really thrash it all the time)
