With help from Chevrolet (who built and own the modified 2015 Camaro SS being tested), Grassroots Motorsports was able to show how actual oil temperatures compare with those indicated on the factory 4-pack gauge. Testing was performed using the same equipment GM uses during their own testing (literally the same - GM sent it to them).

This testing was done at VIR at full bore with track times in the 2:12s, and since I was present that July weekend with my own Camaro, I can verify that ambient temps were HOT.

Note that the car in question is STOCK in terms of the oil system and DOES NOT have an aftermarket oil cooler.

Special thanks to Grassroots Motorsports for allowing me to share the attached pdf with the forum, and be sure to check out summaries of the other stories on their 2015 Camaro SS project track car here. (Full stories are available in back issues.)

Wernergmhtp, thank you for sharing that link!!!

"Our Ultimate Track Camaro SS hit the track again
recently, and it’s holding up as well as ever. When
we left off last time, we were adding heavier oil and
installing a mechanical thermocouple, because we
were seeing oil temp readings of nearly 320 degrees
(or more) on the factory gauge.
Turns out that was a false alarm.
Rather than an actual thermocouple gauge to
measure oil temperature, this Chevy uses a computer
algorithm that takes into account various parameters–
ambient temps, rpm, load, throttle position and
a zillion others–to simulate what it thinks the oil temperature
must be. That’s right, instead of measuring
the oil temperature, it basically measures everything
else and uses that data to model the temperature.
Chevy says the system works
great–except under occasional
weird circumstances, when
it doesn’t. Since this Camaro
sees 90 percent of its on time
at full throttle, we’d say that
counts as weird.
So Chevy sent us a
mechanical gauge and
a thermocouple that we
installed before our
Ultimate Track Car Challenge
event at VIR. The
result: nearly ideal oil
temps. Readings ranged
from about 275 to 285
degrees in the pan,
which we can completely
live with.
In the spirit of monitoring
even more
parameters, we also
installed a cool little
device from Auto Meter
called a DashLogic.
Plugged into the OBDII
port, the DashLogic
hijacks the driver info
center in between the
tach and speedo and
lets you display custom info from the OBD system–
stuff like steering angle, throttle position and
timing. This sub-$300 device installs in about a
second and provides a meaningful service, so we
call it a big win."
