My diesel Mondeo has covered 132000 miles and my independent servicing garage suggested treating the engine to a fuel system cleaner. They particularly warned against using the cheaper varieties that can be bought, and they said that in their experience only STP Ultra and another brand were worthwhile products. I've always been sceptical about additives, but decided to try STP Ultra 5 in 1. I believe it has made a difference to the smoothness of the engine. I used one tankfull's treatment before a 350 miles round trip and I'm sure the car's running better, in fact a slight hesitation that could sometimes be felt on acceleration has disappeared. I'll repeat the treatment in about six months - it's not expensive and can't do any harm.

I used stp 5 in 1 on my 2008 VW Touran 2.0tdi sport, it caused an intermittent limp mode, i would have to pull over and restart the engine, i drove off 1/2 a tank then topped up and it's stopped doing it ... Not a suitable product.

Car was hesitant in places this was recommended to me and it seems to have worked, my car is faster and not hesitant so good so far and has saved a lot of money at the garage

only just put it in the tank along with a new fuel filter and already noticed smoother tickover. granted probably more due to the filter but hopeful that it will give everything else a good clean out.
