For
water, the standard is to measure it as it leaves the engine, which is the
hottest point. I would think that's what you'd want to do with
the oil as well, but unfortunately, there's no practical way to do
that. The oil drips back to the pan from different places, and
you can't measure that return flow directly. You can measure the pan
temp, as I did originally, but it's not the best reading, since there
isn't really a constant flow of oil past the sensor. I
suspect that measuring the oil as it returns to the engine was selected as
the next logical point. I have the pan temp hooked up as an Aux temp
on the EM-2, but I can't say I've looked at it yet. Maybe when
Tracy gets around to that data logging... :-)
Someone else said that the remote
oil filter was a good place to put the sensor, so I'm going to check into
that this afternoon, and see if that is
possible.

Steve, just be aware that the 210F limit referred
to is measured after the oil cooler. So if your filter is after your
cooler then you will be measuring it at the "recommended" point. Not
to say you can not measure it at the filter even if before the
cooler, but clearly if it has not gone through the oil cooler yet, it will
be considerably hotter than 210F. As Rusty mentioned, the oil pan is
not the best place to measure
temperature.

Ed,
My filter is after the oil
cooler. I was pretty sure, but I went to the airport to verify
it, and also remove the sensor from it's old
location.
There is not any pre-made
holes to install the sensor, but there is a flat spot on the top, that
looks to me like it's at the center tube feeding the filter.
Seems like that would be a good spot. My wife went with me to go to
a store, so I only had a half hour or so, and didn't have a drain pan so I
could pull the filter. I didn't have a bolt with the
right thread to put in where the old sensor was, so I may just have to
reinstall the old adapter and insert a 1/8 NPT plug. That may be
better any way in case I ever decide to install another sensor at
that location.
Thanks for the
help.
Steve
