Could be the Oil

[chuck <chuckc@ibm.net>]

Again, 

thanks fer the oil-in-the-dampers reminders (ALLLLL of them).

I just checked. True, the oil is reallly ... reallllly low.
But there is still some suction.
 
Question: It's still winter here in ole' NC. Should I be using
something like Mystery Oil rather than 20W50 in the pots?
(sorry if this opens old woulds).
