CVT Oil additive

[guest7630]

I have a change to do at the weekend, weather permitting. I've read the good advice here and watched a few youtube vids, so feeling confident. In one vid, the bloke recommends using something called Revitalize, it comes in a syringe and is squirted in the filler hole after a flush. Reading the bumf it is meant to renovate worn surfaces in the cvt box. Sounds good but has anyone used it and had any noticeable improvements?
