Well, we only "waste money on fork oil" very very rarely. With conventional forks, even a fairly severe leak means you lose very little oil, and rest assured I've never seen a leak that sounds as bad as this one. To be sure, $20-30 is massively more than what it's costing us. But like I say, if we were dealing with upside-down forks and a bad leak like this, where it seems like the whole damn fork can be run dry, it would be folly not to take action.
