Oil Temperature Readings
Just wondering what you have experienced for average oil temperature readings?
Previously, I was seeing temps in the 95 c - 105 c range under light loadings.
Today, after an "A" service (and oil change) my readings went up to 124 c, again under light loadings, freeway driving at legal speeds and below, and air temperature around 85 - 90 F.
Coolant temperature remained normal around 90 c.
Oil was listed on the repair order as Mobil 1 5W-40 M (Same as was in the car when I took it in).
Any information that others might have to share would be helpful.
Thanks,
JDB

Funny you should post but I had the A service today also and was looking at the oil temps, with 103 C being the highest on a slow drive home in stop and go traffic on an 80 F degree day. I've seen 120's on track days with 90+degs. The engine will shut down when water temps hit 248 F . I dont' know what the oil temp would be for a shut down.
Could it be a bad sensor, but that would sure bug me not knowing and after a service.

With air temps at the track from 95 to 102F, I've hit 136c oil temp and it goes into limp mode until it recovers to 130c which is less than 1/2 lap (about a mile), then you get full power back.

I see 120+ temps all the time under normal to slightly agressive driving. I'm gonna have the dealer look at my oil temp Tstat. I find it hard to believe there is this much deviation in our running temps. Hell I see 120 under mellow driving all the time with 70 degree ambient.

Thanks for the replies.
I'm taking the car back to the dealership this morning to have them see if anything is out of the ordinary.
I'm just not comfortable with this sudden 15%-20% increase in the oil temperature readings.
The funny thing is that if I ignored the gauge reading, everything else seems normal. Nothing else indicates that the engine is overly warm. Past experience has been that when oil temps near this range (approx 250 F) it has been very obvious that the engine was very hot.
I'll let you know what the dealer finds when I return.

Please keep us posted.
One other question....do any of you think these temps have anything to do with the oil being used ? I know AMG changed the reccomended oil for these cars and some dealers still use the other grade...

BTW, I use Mobil 1 5-40 ESP formula M ever since it was recommended by MBZ for the 63's.

Luke, I have an appointment in an hour to bring my car in for scheduled service. I'll talk to my mechanic about it. It's just a guess, but maybe MBZ uses different thermostats, because mine never gets up to those temperatures under normal driving. Even when I lean on the car on a hot day, it won't go past 115 C.

When I drive it hard, it's at 127 consistently. I'm interestd to hear what your dealer has to say.

Sasha - Above, bold, is whats very odd. I can go get in my car right now, run it up and down Loma Vista at a moderate pace in 70 degree heat and it will be 120 by the time I get home.

It's been so long since it was only 85 here that I forget! However even in the 98F to 107F air temp, I would only see 113c on the oil temp.
With air temps at the track from 95 to 102F, I've hit 136c oil temp and it goes into limp mode until it recovers to 130c which is less than 1/2 lap (about a mile), then you get full power back.

My normal oil temp is usually 103c/217f in normal driving in Florida's climate.

Here's my report on what happened today.
Checked the oil level (Mobil 1 5-40 ESP Formula M) in the morning, before starting. It appeared to be slightly overfilled.
I drove to the dealership, about 45 minutes away. Oil temperatures were back within their normal range. Highest indicated that I saw was 100 c - 102 c.
When the dealership looked at the car, the only thing they could see was that the oil level was slightly overfilled, so they sucked about half a quart out.
Drove the car for the rest of the day, and temperature readings remained in the 95 c - 105 c range.
Nothing outwardly indicates that the engine had overheated at all. I think it must have been a bogus reading on the display since everything else seems normal. No warning lights, no overheating of the engine coolant, etc. Doesn't give me much confidence in the oil temperature readings from here on out. I hate it when they cry "Wolf". I hope I never see another high reading like this, again.
By the way, all components are as they came from the factory. No special tuned ECU, etc.

Luke,
Thank you for your additional comments.
I understand that your car has regular temp readings in the 120+ C range. So, I agree with you that that must be normal for your car.
I purchased my car new, and during the past 34 months and 9,800 miles of driving, the car has only indicated readings above 115 c during a track session on a day when the ambient air temperature was is excess of 100 F.
This car normally runs in between 95 C - 105C, so the nearly 20% increase in the gauge display really concerned me. The strange thing is that nothing else that I observed was consistent with this abnormally high (for my car) temperature display.
I'll be watching the temperatures, but based on yesterday's driving, both before and after the oil level adjustment, the readings stayed within the 95 C - 105 C range.
The cause of the 124 C reading, which I still don't believe was real, still remains a mystery to me.

Do any of you especially when tracking the car ever put 10W-60 in? I have used it alot from my E60 M5 days and it seems to stand up to abuse well.
Just wondered if the OEM Mobil 1 was working well on track for everyone.

I use that grade Castrol in my M6. It's specifically designed for BMW M engines.

Why risk a warranty claim? The stock oil seems to perform well and the full package is designed for the track.

And please let us know what your dealer says about these elevated oil temps...Specifically, I'd like to know what kind of Tstat setup our cars have...BTW, what dealer do you goto ?

At the risk of going a little bit OT, here's a link to an oil test that doesn't show Mobil 1 in the best light.
Of course, I'm sure most of you aren't surprised given the the deep pockets that Mobil has and the value of being named by MB or BMW or other high profile marques.
No association or interest in the oils or website, nor can I vouch for the accuracy. Have I covered myself? I don't know spit about oils.
Back on subject, sorry JDB.
