Oil temperature on track....a question or 2 please....

[John W (UK)]

Hi guys,
I was at a track day on Saturday, and the weather was only mild, not exactly hot. My car is a Sport Evo with MoTec , 284/272 cams (see post below). There was some debate at the circuit about what is the highest acceptable oil temp our cars should run at. Mine hit a steady 115 degrees after several laps on the circuit. It runs at about 90 in daily driving. Is 115 too high? One guy with lots of knowledge recommended I fit a bigger oil cooler from an E28. Do you think this would be a good idea?
Another bloke with a Sport Evo hit 135 degrees. He new that was too hot, and stopped lapping the circuit.
Thanks for the input,
John W (UK)

I posted at roadfly as well but i trust here more...

That sounds really low to me. I go by the oil temp gauge in the bottom of the tach. My car runs all the time when warm just under 210F If I push it hard it will go above by a little. Is My car running way to hot?

It is fine. IMO (not that it's worth much )

Your oil will run hotter when driven hard ,also during 100º days and 85º days in stopped traffic (for long periods of time). Just be aware (like you are) of it and don't run it too hot for long periods of time(make it brief). Shutting the car down and giving it a rest is a good idea.

Some track goers change their oil after every event, and I was told that some even double change their oil (Stan) to make sure they get out all the sludge.

Will the electrical fan upgrade spin air through at a faster rate then stock?

I'm sure John is quoting temperatures in degrees celcius.

210F is fine.

Yes, I'm sure the reading in my car is celcius.

I think the manual states a max of 130 deg when being driven hard.
What oil are you running John?

[John W (UK)]

Martin, Bexleys put in Mobil 10/40 semi-synthetic.
Can you try and confirm the figure of 130 degrees please? If that's true, then I nned not bother with the bigger oil cooler. Cheers, mate.
