We have had some very slight issues with C-12. Neither car has been tossed, but we have been told it read marginal. Normally, adding some fresh C-12 resolves the issue. Each time it has happened we've been told that it has gone somewhat "stale" from being exposed to the atmosphere (in a vented fuel cell between races mostly). We now usually drain both cells down to about what we need to load the cars and unload them later. Then we just add fresh C-12 before time trials. I guess C-12 is somewhat sensitive. But I like the results I get with it, so long as I don't have worse issues, or need more octane, we'll stick with it.
