Diesel Addtive/Treatment

I am on the look out for some new diesel treatment for my motor.I have been using Millers Oils diesel treatment from Halfrauds and have just used the last of it,i used this in my old B6 and used the last in my B8 today,i have been recomended to Forte treatment but never used it before,anybody used this stuff,recomend any other or should i stick with Millers??

Thanks
