I "T"'d mine into the oil cooler off of the OEM single wire oil pressure unit. Lots of people say it is innacurate at first it was apparent that it was because it was reading 10* below ECT. I contacted the company since I had a problem with the gauge and they sent me a complete gauge/sending unit assy. I replaced both and it looks like the sending unit was also bad. Although I have no way of checking the gauge accuracy (scangauge etc) I can only ASSUME it reads correct. The reading is equal to ECT unloaded.

OK, now we are getting somewhere.
If it is your goal to have accurate measures that you can compare with others, there is only one scientific way to do it.
Use the built in EOT / ECT gauges readings.
The reason is, if you change the sensor location, or the sensor, you are going to get an incomparable reading and Ford's recommendation for acceptable spreads goes out the window.
If you are a bold, experimental scientist type, you can hook up the gauge elsewhere (like on top of the oil filter as you did), and then religiously log the readings, AND compare it with the logged readings from the built in sensors.
But that is going to a lot of trouble.
IMHO, you are best served not by an external sensor, but by the built in sensors.
That reading is instantly comparable with everyone else readings --- and also valid with the Ford temp spread spec.

Um, there is a built in EOT sender in the 6.0.
You can read it off the OBDII port.

That and price is why I like the ScanGauge ll. All readings from the OBD which is where the ford sensors report.

It would be very hard to install another sensor and then compare the readings with other people reading the factor sender.
The calibrations have to be done from scratch.

That's why I like the OBD sensors, esp. oil, they are internal where you want the readings. No parasitic loses getting to your a/m sensors.

It is very hard to get people to do good science and engineering.

OK, OK I get it, taking the EOT from the OBDII is the best way. I on the other hand want to and have gauges installed. Like many more people I like gauges (manual, dial type). So if you can't advise me on my sender location to get engine oil temps. You are more then welcome to sit back and read what others have done, in ways of installing gauges (manual, dial type). But don't keep harping on me that the only way to get EOT is by way of OBDII. Your starting to sound like my wife.

Hey bud,
Above was not directed at you!
I have more sensors deployed on mine than you care to know...
From optical (cameras) to IR, to instrumentation, to sensors for whatchamacallit.
None of them OEM.
Problem is... I got to read all that data and make sense of it.
I am laughing at myself.
Best Regards,
Come to think of it... next project.. my own UAV flying overhead to scout out the road...
