Where does engine oil temperature readings come from?

My guess is the oil quantity probe in the oil pan. Am I right?

To answer myself, no, there is a separate sensor located above the oil filter mounting boss, which on my car, is one of the cleanest parts of my car due to my using K&N oil filters which do not leak.

I have had a problem which I have posted here and other places. I have asked Corvette racing shops, and nobody really had any idea about why it was that my observed oil temperatures during competition had increased by about 30 degrees, while at the same time my car was slowing down. it looks like that a loose exhaust flange was allowing exhaust to impinge on the oil pan, apparently heating things up, and losing performance at the same time.

Another item on the checklist to look at.

HI there,

I must have missed that post.

Any oil temperature will raise when in racing competition, although I do not know what type of competition you are doing.

BUT, Mobil 1 is good to over 500 before it starts to burn, so i am sure 30 degrees will not hurt you.

Oh, and the oil life monitor will take that into account when calculating oil life.

Allthebest, c4c5

What I meant to say was that oil temperatures had increased by about 30 degrees higher than what I had seen in previous laps, and apparently was caused by the exhaust leak, which I'll be able to verify once I get the car out again.
