Hi dear members!
Today I drove for about 300 km on the motorway and I wanted to use a little my engine, so I began to set the cruise control at 220 or so.
But over 220 kmh the cruise control deactivates and you have to keep the pedal down with your foot.
So 230, 240 etc. and the SMG, in sport mode, never upshift to D6 but remains in D5. (and this really sucks imho - okay at 150 kmh, but at 220 or more it's stupid keep the D5)
Add that I have a higher ratio in the differential, so the car stayed at more RPM than a normal 545i SMG.
In short word, I saw the oil at 130? C on my cluster.
Once at home, I thought the M5 must have a bigger oil cooler, with a 8500 rpm engine.
But on bmwfans I see:
M5:

545i:
Click
so at the end I have a radiator for the oil of the steering (lol) but not for the oil of the engine ?!?!
In some days I will add an oil cooler on my tuned Mini Cooper S because it doesn't have it.. I'm worried I will have to do the same on the 545i.
But.. Is there the space to add an additional radiator? I think yes, as the M5 has it.
Edit:
does anyone have a pic of his M5 without the bumper or of his 545i /normal E60, to compare..?

I see many radiators on ebay.. But maybe they would require custom hoses or similar.
On the Mini I will attach a plate with hoses under the filter (see the pic) .. I don't know if it can be the same on the 545i.

Come on guys, it's a serious project!!
I bet in August I would have 150? C.
Come on, don't be gay with those bumpers and splitters.
Check here:

What is GULF VERSION?
Cars for Dubai have something different?
In this case, retrofit.

Yes, I thought the same thing for adding an extended Oil cooler on my 545i, I always gets the Temp above 120C (above the 160km/h) in the summer if I drive hard the car but in the Canadian winter it is natural cooler (-30C) 
IMO, get the aftermarket cooler! I would buy it.

Ok, I'm not the only one, this is already a beginning.
Any member from Dubai here?
If yes, can you call your dealer and ask if your 545i/550i has a radiator for the oil?
My problem is I'm starting driving fast and all my cars will go on fire if I don't pay attention

This is an adaptor..
Can you see those junctures? THERE you can attach any radiator you want. But.. Members from Dubai, we need your chassis number and I'm sure I would see an OEM radiator or so: if they sell the connection, they have to sell also the cooler.

give Eloy at RPI a call, 562-630-5966 or PM him. They make oilcooler for M5/M6. http://www.m5board.com/vbulletin/m5-e60-gr...er-upgrade.html
I have one on my M5 and I did 30+ passes on 1/4 miles in just over 2hrs and no problem with temp.

Picture comes from keang24's link above, which in turn links the install page.
