Re: Synth vs Dino

Paul,

Don't get this thread started again...... :-)
Whatever oil you use is totally dependent on type of engine, useage 
etc. To save BW and for a more definitive answer take a look at: 
http://www.shell-lubricants.com/aviation.htm. You are probably aware 
that Mobil did have a problem with their synthetic aviation oils for 
small piston engines, but this has since been remedied.  

Our flying club uses Aeroshell semi-synthetics in all our aircraft 
coupled with a progressive maintenance schedule. Temps ranges here in 
the Midwest go from 35 below F to 105 F. Multigrade synths. and 
semi-synths. are ideal for such applications.
