Oil Temp Gauge
Just took my F to the track this morning...had a great time! I did see my oil temp gauge climb and was wondering if anyone knew what temp each bar represents. Under normal driving the gauge reads at 3 bars which im assuming is about 220 (total guess). At the track i saw 5 bars for sure and i think 6 before i started my cool down. Any help would be great thanks!

I've seen 6 bars at a track day with 102F OAT. Here's how the gauge indicates.
FWIW, these pics are from the 60k mile valve lash inspection. Zero evidence of varnish from oil too hot here.

^^This is exactly what i was looking for, thanks! But just to clarify the chart...the arrow that points to the right and then up is showing the temp at which the bar will become illuminated. And the arrow that points to the left and down is when the bar will turn off, correct? So for example the 6th bar won't illuminate until engine oil has reached 266, right?
thanks in advance!
thanks in advance!
does the engine ever get damaged if you pass a certain number of bars?

Voltage measured at this point will vary as the engine temperature is changed.
The engine oil temperature gauge displays the engine oil temperature using seven bars. The meter CPU calculates the engine oil temperature based on signals from the engine oil temperature sensor via the direct line. When the engine oil temperature becomes 140°C (284°F) or higher, all the bars blink and the warning message is displayed in the multi-information display.
