I did a bit of research on this stuff prior to getting my car and from what I had read opinions were mixed, some swearing by it and others saying they could see no difference. My 2p worth. I've had the car for a month now and filled up 4 times.
1 £30 of Tesco diesel when I picked up the car
Wife commented when I got home that it seemed to smoke a bit as she followed me home.
Got me a bottle of MillersDP4 from ebay £11 delivered.
2 £40 Shell Vpower plus a dash of Millers.
Kept an eye on the smoke and it seemed to chuck quite a bit out, beginning to worry about it now.
3 £40 Shell Vpower plus splash of Millers.
Still smoking a bit when booting it but seemed less dense
4 £40 Shell Vpower plus splash of Millers.
Getting toward the end of this fill up now but the dense smoke has now gone altogether with just a fine haze when flooring it.
I'm now much happier and the engine does feel smoother, as to whether it's any more powerful I'm not sure as I'm getting used to it now.
So its a thumbs up from me
