liqui moly oil additiv mos2

Friends, I think to add new oil into the oil change. Are there any benefits or harm? Would you recommend.

I do not recommend this type of contributions, teacher, if there is no problem, I think I do not see the need to use it. 8 years ago, I used this type of product in my megen 2 vehicle and it seems like it wasn't useful. Of course, this liqui is a brand that does not compromise on quality in moly products.
