Hello forum members and thanks for having me. I Have yet to find any consistent advice on seafoam treatment for my 2015 MCS R56 (b46 engine) w/ 40k miles. I pump premium every time and do a lot of long distance drives. I do not know how badly, if at all, I need to do use seafoam--I am just used to doing so on my old land rover and wonder if Minis like it as well.

First question is do I need it?

Second question, if yes, which PCV hose do I put it into? There is a large one and a small one and I cannot tell exactly where they lead. The small one seems to create more suction so I figure its that hose.

Any advice would be deeply appreciated. Glad to be a part of a new forum!

You don't need it.
