I've never had a Co2-filled tire deflate any faster than a regular pump filled one. And CO2 is all I use on the road. Maybe you didn't get whatever it was that cased the flat fixed?

Reminds me of the Sheldon Brown/Carapace posting:

CO2 is heavier than air, you will make your bike heavy and slow if you
use it. Helium is lighter, the only way to go if you want speed and
safety.

If you are willing to live dangerously, Hydrogen is lighter and cheaper
than Helium, but don't smoke while riding your bike if you use
Hydrogen...
