What is the proper operating range of engine oil temperature?
I just installed a bunch of Innovate gadgets and I want to set an alarm if the oil temp goes too high. I've been searching but there are conflicting recommendations.
For water temp it's actually easy. I use the OBC Hidden Codes (http://forum.e46fanatics.com/showthread.php?t=44922) and just observe function 7.0 (engine coolant temp). I see that coolant temp ranges from 88°C-98°C (190°F-209°F). It's at the lower range when driving hard to protect the engine and at the higher range for fuel economy (you gotta love our electronically-controlled thermostats).
Unfortunately there's no OBC function to read oil temp. I can only read it using a laptop based scan tool. So what's the maximum safe operating oil temp?
In case you should ask, I posted here since people who browse the FI section are a lot more knowledgeable about engines and gauges than any other section.
