What does your oil temp run?
I read a while back that someone's electric fan on their oil cooler decided to stop working, and their oil got into the 260 range. I've heard a high pitch fan come on before and was assuming it was for the oil cooler. Mine usually runs in the high 22x range and sometimes into the low 240's. I know when the oil is "cool" the numerals in the dash are blue, if it becomes "overheated", do they go from white to red possibly? And also does anyone know at what temp the cooling fan for the oil cooler comes on? Thanks, and if it helps the car is a 2012, with about 5thousand miles.

I have the same high pitch noise I think ( I posted a thread with a video )..does it come on around 80C and is kinda coming from the driver side? My car runs no where near that hot..that seems pretty hot..mine runs <115C (Are you talking about F?) and that's when I'm ripping it.

i noticed that before i had the B service done (which included an oil change), i seldom hit 210 - and i'm in Texas!!.. now after the service - and the dealer used Valvoline, i easily hit 200-210.. not sure if its because of the new oil compared the the previous one it had (i'm guessing Mobil1).

I am normally never higher than 200 in fl heat/traffic And sometimes I'll drive it real easy in comfort and I've seen it go down to 172-180. under a bunch of runs 215-220

Reached 266 in 80 degree F weather on track tat SPR this past weekend. Not good, hot, hot, hot but no limp mode which seems to be 270 for me. My normal street temp is 215 these days.

In the DC metro area, during rush hour (I avg around 8mpg at around 10mph over a 30 mile trip each way), my car hits around 230'F
Cruising at speed, it hovers between 210 and 215'F

"Conventional oils will tolerate engine oil sump temperatures of up to 250 to as much as 275 degrees F without difficulty. According to Quaker State engineer Mark Farner, oils like Quaker State's full synthetics can easily withstand sump temperatures in excess of 300 degrees F, and he says that some oval track race teams are experimenting with temperatures as high as 350 degrees F. For a typical wet-sump engine, 300 degrees F is still extremely hot, but Farner says that synthetics, because of their molecular makeup, are better suited to withstand these temperatures. The downside is that additive packages do tend to break down faster in high-temperature environments, so if you plan on running oil temperatures in excess of 300 degrees, this would mean changing the oil after every track event regardless of the mileage."
While I have no knowledge of the specific testing for MB 229.51 approval, most modern oil certification tests include running the oil at 150 deg C (300F) for 100+ hours without significant degradation of the lubrication properties.
If you're repeatedly seeing your oil temperatures creep up into the 125 deg C (250F) area, chances are you've got other issues to worry about.

I think you guys are using the term 'limp mode' a bit loosely. Limp mode is associated with a failed sensor and is a pretty severe condition. 270F (if that's the right temp) would likely cause a reduction in timing, as would an increase in water temperature over a certain threshold for example.
As long as you're using a fully synthetic oil, I wouldn't worry until you're seeing 260-270F. If that happens, stop using the factory 10W30 and get a hotter grade oil. 10W30 is a compromise that the manufacturer uses for a good all-year-round oil. If you plan on racing in 100F weather, you better believe you have to make some tweaks because that is not expected use for this car. There is only so much that can be done in the factory and we need to take care of these cars when we go to these extreme cases.

The M156 motor requires MB 229.51 spec 5W40 oil, or possibly (again, MB 229.51 spec) 0W40, year-round in pretty much any climate. Anything thinner on the top end and you will cook the engine.
