 Not sure if I am the best person to be offering advice here (I am not flying
yet),
 but here is what I have heard from reliable sources.
 
 1)  The Legacy tends to run high oil temps
 2)  This is exacerbated by having the oil cooler door option.
 
 I posted a question on the LML several months ago and asked whether others
had
 the oil cooler door option and whether they needed it.  Only one person (who
operates
 over the Rockies in the winter) said that he needed the oil cooler door to
keep oil temps
 up.  Based on this I decided to eliminate it.  I have heard that eliminating
the oil
 cooler door option will result in better air flow through the oil filter and
lower oil temps.
 
 Do you have a remote oil filter?  This may also help a little. I plan to have
a remote oil filter
 and may try using a "cool collar" (http://cool-collar.com/) which basically
wraps metal fins
 around the oil filter.  Don't know how much improvement in oil temps this
will produce - they
 claim "up to 23 deg." - I suspect this is optimistic and would be happy if I
got 5 deg.
 
 I plan to test this summer and do flights with and without the "cool collar"
under similar
 conditions to see how much difference it makes.  If you try it, let me know
your results.
