Just an FYI:

Gas shocks still use oil as the damping medium. They just have a gas 
pressurized reservoir that works to make sure that the damping chamber is 
always completely full of oil, even as some leaks out past the seals.

These work until the reservoir is exhausted, and then you have a shock that has 
failed in a different way. I can't explain this any better without pictures, 
but if you really want to understand how they work you'll have to take one 
apart.

Hint: take apart a failed (unpressurized) one. NEVER try to take apart a good 
one unless you already know what to expect.

BTW, the ones I took apart were Bilsteins from a Mercedes. After taking them 
apart I read in the manual that rebuilt ones were available. It was interesting 
to realize that these could actually be taken completely apart AND put back 
together again. Of course on my first attempt, there were a couple of parts 
that I broke....
