I have mine in my drain plug. I see about the same temps as everyone else.

If I mount an oil cooler I might see different temps since I'm metering post cooler but pre-components. I can always move it to the pan, I have the fitting. I'd just have to remember when I do an oil change.

Mine is in the pan, unfortunately on the driver side and I'm worried that I see hot oil from the turbo...if its really that hot. Maybe not, who knows?

I think you should put it on the sammitch plate.

I put mine in the rear of the pan, bottom of the sump. The exact temp doesn't really become an issue until your into the failure zone anyway- it's more about watching trends outside of stable. That said, I'll be willing to bet that the oil traveling in that long line and avoiding the combustion area is significantly cooler than the oil that's just been through the combustion process.

I see below that with my 25-row cooler - around 175F usually when driving around town - but I measure at the sandwich plate.

On the track I see 250F there when I gun it.

How did you do that without it leaking? did you just use a normal fitting with a place for a sensor or is there some site that they sell a special one of those? I've recently had that idea but didnt think it would go too well.

I have my sensors (pressure and temp) in a sandwich plate at the filter. I see the same 200-220* temps. as well. Easy to see when the temps start to get higher than normal and the pressure gets lower than normal that it's about time to change the oil.

Autometer sells a plug that is tapped for a sensor.

Those like to fail.

I just used a cheap bulb type sender, then used thermal epoxy to stick it on the rear of the pan.

Reads high. I can easily get 220*F driving on mt. roads on a hot day.
