It is Hot.. rediculously hot.. how hot is your engine running in the heat..

And the weather report for the next few weeks...


(Stolen from my wife who posted it from twitter.. so not sure who posted the original).

Anyways.. my engine's been pushing 230 to 240.. way outside the usual range of 210 to 220.. I'm a little concerned.. This is regular driving too.. not even spirited.

It's really hot here in the SF Valley of SoCal too...around 100 degrees!

My engine oil temp hovers from 215-221 F at speed in this weather, a few degrees higher than what I typically see in cooler weather. But if I get on it at all, the temp will quickly climb to the 230-240 F area.

216F Still pulls like a train. I do miss the cold performance though.

Hmmm, that seems really low compared to what I've typically seen and heard of others. What oil and weight do you use?

i just think that the oil temp is a flawed indicator on the c63. the temp ranges are just too far off to be accurate. I mean, there is a 50 degree difference between some of our cars.

all factors considered, i just dont see there being this large of a gap in similar (if not identical) engines. i know im in texas and its hot as **** hear but i know other people in texas whos engines run 30-40 degrees less than mine

so, my vote. the things just isnt a reliable temp gauge.

So, if we cannot rely on the oil temp sensor.. then we have a problem....

I mean, I understand that it is not just the heat that is a factor, there is the 80% humidity that plays a role (and the humidity value will differ greatly from area). The other issue could be an under-performing oil cooler (I am going to see if I have leaves and crap in there this evening that could be impeding airflow)..

I'm just a little worried.. Today is going to be 102 in the DC metro area, 115 to 120 is the heat index with the humidity.. and the pollution in the area makes it worse (well on the human body anyways)..

My oil temp stays at like 217*F and if I drive a little more spirited I will see 226*F. This is in 100*+F weather.

I've never seen anything over 23x*F in my car.

I just returned to Germany from the States (New York) and it was hot, since I have been back its rained everyday and gets into the high fifties or low sixties, even had to turn the heat on in the house at night.

We aren't baking souffles here, folks! A 20F+ difference in operating temps between hot and cold weather isn't going to hurt a thing.
