Do I have to change my hydraulic fluid after I apply BlueDevil?

NO. BlueDevil mixes with the fluid and can stay in the system.

Can I reapply BlueDevil?

YES. BlueDevil does not contain petroleum distillates, which can destroy seals after temporarily expanding them. It is safe to repeat treatment if other seals leak in the future.
