I run the cheapest stuff the parts store carries...but I change it out 
when I'm supposed to.  Filtering out the super fine particles is a red 
herring.  They're to small to affect anything.  The biggest problem your 
oil has to deal with, especially with aero-engines, is the acidity 
build-up.  There is no oil or filter, synthetic or otherwise, that will 
deal with the acid that comes from burning an organic compound that 
turns into water and CO2 over a long period.  Especially, when you add 
in even the small amounts of sulfur known to accompany all fuels.  It's 
the acid, not dirt, that kills engines. 

At least that's what
  -the Aeroshell expert at Sun'n'Fun
  -and his data
  -and everything I've ever learned
 said.
