Oil temperature in sump VS engine heat - general question Sign In

Hello,
I wander if there is a way to detect the engine overheat situation by monitoring the oil temperature in oil pan/sump?

Is there correlation between this oil temperature reading and the engine heat parameter which is used to generate Engine OverHeat alarm to shut down the engine in order to prevent damage?

Thanx

Of course there is a correlation between coolant temp and oil temp but if you try to rely on oil temp for warning you will be buying a new engine.

There already is a system designed to shut the engine down in case of overheating. It's called the DRIVER!

Yea, the DRIVER is good idea, but lot of privet drivers do not aware of existence of temperature gauge and need warning.
In some of the newer models there is a function which monitors the engine heat and shuts it down in case of overheat.

Why do you so skeptic about monitoring oil pan temperature?
Does the oil temperature follows the engine temp with large delay? Or there is a problem with calibration between them?

And you expect them to understand an oil temperature gauge? If it was an air cooled engine, yes you would need an oil temp gauge and exhaust temperature gauge also. Coolant and oil heat up at different rates. Some engines have an oil cooler, so the correlation would be null.

Most newer vehicles have audible warnings along with instrumentation to signal the driver of an over heating engine. If the driver is ignorant of that system, they shouldn't be driving the vehicle.

Some vehicles will actually deactivate cylinders, but not disable the engine, in attempts to cool the cylinder heads down. You really don't want your engine shutting off because it is overheating. That would be a safety concern and open up a whole bunch of doors for liabilities on the manufacture.

I could read it now. Driver gets T boned and killed crossing intersection because coolant fan didn't come on.

I don't know... my car is 11 years old Frown
Maybe they just slow down the engine...
But what R U saying about the temperature correlation?

OK, you're probably right...
So i'll re-define the question: for your opinion, is there option to produce the audible warning reliably based on the oil temperature?

Sure, if your vehicle is equipped with an engine oil temperature system, you can have an audible alarm if the oil temperature gets too high. It's not going to help determining your coolant temperature though, which the computer needs anyway for fuel and ignition timing calculations.

Yes, even if you make it work, it won't save your engine because it will have already fried by that time.
