Hard to tell with the description given.

Is the car overheating?
Is it rough idling? (Not DoD rough idle. Worse than usual.)?
Any change in behavior/performance?
Any Mods?

What color is the oil? If I remember correctly our radiators also house a trans cooler on the bottom, if the oil is red, then there might be a leak between the two.

Are coolant levels depleting?

Could be a few things, could be a blown head gasket, damage to heads/valve-body. Or someone had a special moment and poured the oil into the wrong orifice.

I'm by no means an expert, but that comes to mind.

Did you actually test for coolant in your oil, or did you just not see milkshake?

Yes, the trans cooler is in the bottom of the radiator. I'd start here.

Welcome to the forum. Check the engine oil dipstick both for oil level and hue.

Which oil light....does the instrument cluster read check engine oil or service engine oil? Check engine appears when oil pressure or oil level is too low. Service engine oil deals with the oil life monitoring system and might necessitate an oil change and/or resetting the oil life monitor. Our vehicles use DEX-Cool and it turns a coffee/mud color when exposed to air. Is only the fluid on the radiator cap this way? Have you checked the coolant reservoir dipstick for fluid color/consistency? Hopefully, the only thing needed to remedy the problem is another radiator cap.

It said check upur oil
If its check and not service, then that usually means that there is something with low oil level or low pressure.

When was the last time you've had the oil changed? Or coolant changed?

Also, is the car stock?

Has it had any work done on it?

You can see the oil filter housing easy on alloytech. If I am not mistaken, oil filter housing should be sitting on the drivers side of the engine, in this capsule looking thing. Common failure point on it happens when its over torqued, i think proper is 9 lbs. Has a tendency to crack. Take a look, if its looks all nasty, could be it.

However it wouldn't cause the oil to appear in the radiator.

From the completely un-educated here, it may just be sludge that builds up over a number of years/miles.
My V6 is about to roll 200K, when I had my cooling woes last year got the milkshake gunk in the rad cap.
Cleaned it up and haven't seem it since.
My oil is changed every 7000K, the coolant was swapped out at 140km when I got the car and 3-4 times more because of my cooling woes.
Not much more here to help other than....that's life owning a G8, clean it up and keep an eye on it.
Good luck.

I agree, I mean if there is no evidence of coolant getting into the engine block, and the engine is not overheating. (Or sounding like a running diesel.) Then I'd just change the oil and coolant (along with the oil filter) while examining everything for any abnormalities.

Probably the 100% way to determine if it is really engine oil in the radiator. If the brown stuff turns up as globs (think lava lamp) after you collect the fluid then its engine oil. If its just brown colored, then that is just dirty coolant.

The worrying part is the oil pressure/low level warning. If that came up but the engine is running fine and oil & Cooler levels are normal, (no weird behavior from the car either) then it might actually be a bad oil pressure sensor giving you a false positive.

But I'd definitely change the fluids first and examine for any signs of leaks/cracks, to rule that out. After wards you can take it for a test drive to see if there are any changes in behavior. Aside from car acting a bit more 'awake' from having fresh coolant put in.

As for oil filter housing, there are a few videos on that on YouTube by Aussie mechanics, I don't remember the title but your car trim is called Holden Commodore VE SV6 in Aussie-land so searching for that may help.

Could be the oil pressure sensor port is clogged producing a lower than actual pressure reading. Try removing the oil filter and cleaning the inside of the housing with a suitable solvent. Alternatively, disconnect the sensor and connect a manual gauge to the port for a numerical value. Good luck
