Hello
Has anybody (especially diesel drivers) any experience of using the Unicat 4 fuel additive. I have read about it in a Diesel driving magazine and checked out their website www.Unicat4.com.
Apparantly you can add it to petrol or derv cars, and get more power, better fuel economy and less smoke emissions all at the same time, without getting your car tuned. Sounds too good to be true at the cost of only about £12.00 per 5000 miles driving. I'd like to think what other Audi Drivers think, or if any of them have used it.
Regards
