Oil Temp Indicator

Does the blue line below the oil temp indicator mean the oil isn’t at operating temperatures? If not, then what else does that line mean?

Also, I love how the numbering scale they show is kind of pointless since the value of the shown bars are variable.

Yes that is what the line means, the filled bar above the line shows what the temperature is currently is and if the bar above the blue line isn't filled, the car is not at the operating temperature, the red as you expect means it is overheating if the bar ever reaches that.

although the above response was confusing at first (using the word filled rather than past). That is correct; the white bar (above the blue line) is "live" meaning this is the oil temperature in real time. If the white bar is not past the blue line below, the oil is cold and not up to optimal operating temperature. If the white bar goes up to and past the red bar below it, then your oil temperature indicates that your engine oil is overheating.

Thanks for clarifying, I realized it is confusing as well.
