[ercoupe-tech] Engine Oil

[robertbartunek]

I am currently using Phillips 20-50 in my engine that has about 60 
hours on it.  I have been asked if I want to start using Aeroshell 100 
at my next oil change.  The airplane is located in Florida and I am 
told most people here use the Aeroshell.  I don't think it is a good 
idea to switch viscosities, or so I have been told in the past.  What 
is the current thinking on this subject and does anybody have a 
preference for either engine oil?
