The concern is for a gradual process of unwanted deposits. Just because there is no issue after 7,500 miles dosent mean there hasn't been a negative effect than can be abated by taking action. "As soon as possible" isn't a life or death immediate action, it's as soon as he/she can get around to it for the best interest of his/her vehicle.

The OP can do whatever they want and I have zero investment on whether or not the engine has any ill effects but the last thing I would want to do is not provide advice and just take a "wait and see" approach with someone else's valuable asset.

Perhaps this additive still not healthy to turbo, but I searched and did not find any data supporting this notion.
