overheating

[ray thomas]

had my car to dealer says oil temp at 160 is normal after just a short run cooling fans on 15 minutes driving manual 4 th gear

160 Fahrenheit or Celsius?

 

[ddgermann]

F I hope.
160 C oil seems hot to me.

It better be Fahrenheit.... 160 C is 320 F.... And since motor oil starts breaking down at about 275 F, well.... take it from there...

 

[Rruuff Day]

By the way... that 275 F temp for oil break down is for petroleum oil.. synthetics will withstand higher temps but if you're running 320 F engine oil temps, I would be concerned about long term engine life, synthetic oil or not....

Wow... A little checking and.....yup...I'm old school for sure........ Mobil lays claim that Mobil 1 Synthetic will protect up to 500 degrees F... Careful pulling the dipstick!
320 F still sounds high though... Am thinking that has to drive coolant temps through the roof too....

Yeah 320 F is super high. Hopefully it's just a temp sensor gone wrong. What are your water temps at?

Found this little gem today.... According to this at 160 C you are running 20 C hotter than the max expected track temp. And thats light driving which also according to this should be showing 80% lower temps.
This says max temps. I'm going to check the temps on my Z when I get home....

I can see this is going to be a great thread...
Think we need an expert to chime in here.

Ok ignore the 80% thing. I didn't read close enough.

That's not normal. As the posts above mention, even on continuous track duty your engine oil temps shouldn't get that high. I'd suggest talking to a different dealer, perhaps even notifying GM corporate. I'm sure they'd much rather pay out a smaller warranty claim than a replacement engine later.

thanks so dealer is right?????????????????8

 

[ray thomas]

is mobil 1 still the oil of choice all i used in my porsche cars

 

[ddgermann]

Seems to me the jury is still out reading the posts.
Mobil 1 is the oil most of us use as recommended by GM.
Did you see the posts on Mobil 1? Did you buy your car new? What are you driving? Z06 15,16 or17? Love to see a pic man.

And super hot feet too !

Lol.... Heat Shield Mike.... Heat Shield.... The savior for most Corvettes.... Especially the ones running 500 degree engine temps... Actually the C7s seem to have beaten that trend.... A bit disappointing on occasion though as the C6 definitely kept cupholder coffee warmer... Guess I can live with that....

 

[ddgermann]

My C7s got a bit warm inside along the centre. Nothing like the C6 though.
Ya good for coffee but not so good for a can of soda water.

 

[MikeysZ06]

I can't believe how hot my tunnel gets sometimes. Hence the reason I'm not a hot weather driver. Anything above 20 cel,I cook !!
I do not like heat,or sun.

I was first introduced to the heat shortly after I bought the car. I had a caramilk bar in the centre console. After I got home,lol. Ooooookk !!

 

[Rruuff Day]

The 7 is nothing like the 6 was on a hot day.... Never complained once though and if I had room and could afford it, I would still have my 6 as well as the 7....Warm toes and a big smile... I will take them both....
