         Good idea; I'm doing a leakdown test now to see how much, if any, 
it does leak down with the outlet valve closed.

         They DID recommend changing the oil after 50 hours of use (that 
may take me a while).  I'm running compressor oil right now; when I run out 
I may try the synth, but it's going to be a while...
