I'm pretty confident in the oil side of the equation. The digital readout is aircraft certified, and the specs are +- 1/2 degree. The sender is also aircraft type. The water temp is automotive.

The engine doesn't seem to be really hot when I land, which also makes me wonder about the accuracy. With that said, I also think that my air flow through the oil cooler is a little on the low side.

Mark,
You=20 raise a good point.  I'm pretty confident in the oil side of the=20 equation.  The digital readout is aircraft certified, and the specs = are +-=20 1/2 degree.  The sender is also aircraft type.  The water temp = is=20 automotive.  Its anyone's guess how accurate it is.  The = sensors=20 aren't real expensive, so I may just order another one, and see what I=20 get.
The=20 engine doesn't seem to be really hot when I land, which also makes me = wonder=20 about the accuracy.
 
With=20 that said, I also think that my air flow through the oil cooler is a = little on=20 the low side.  I don't want to rob any more form the coolant side, = so=20 another scoop seems to be the answer.
