Silkolene proboost

Hey everybody! I hope every single of you guys still doing fine and may our lovely cars help too!!

I have seen some people on the forum talking about Silkolene proboost and I found it for 12£ per litre and I was curious to see if it was and mainly if I really need to add to my car. I am absolutely satisfied from the engine and I was thinking of buying it only because I see that clears the injection, more like for maintenance purpose actually.

So what is your opinion, does it worth it, pros and cons maybe?

Also, if you recommended it, what are the other alternatives?

Thank you in advance and keep safe!!
