Hi guys iam a member of another forum as well as this one. It's passionford as iam a cosworth man too lol, and recently theres been a thread started about adding 2 stroke mineral oil to a tank of diesel about 250 ml to 70 litres or something like that and everyone's ranting about it saying how amazing it is being quieter better acceleration and more mpg. I have tried this in my td5 but am unsure if I've noticed any difference. Is this wise to do this to my td5 and has anyone else heard of this on here. Theres not one bad thing been said regarding this on the other forum just thought I'd ask the pro's lol
