Better to be proactive rather than reactive

Millers, it's expensive but it gives me an extra 3 mpg. in a non turbo diesel, and keeps things clean. It has been tested and it raises the cetane value by 4 points.

Non of these snake oils will stop the fault from occurring.

how do you know?
admittedly im not sure whether to use one of these or try the non supermarket fuel first

Technically it may not even be the issue, but it certainly will help changing fuels...

A colleague of mine had the same problem in his company Zafira. The lease company have now given up with it and took it off him to sell/scrap with 65000 on the clock on an 06 plate

Not suggesting they will cure fault. Just answering OP's question "Which additive to use?"

You'll be wasting your money with fuel additives, and I doubt the fuel is the source of the problem.

Look elsewhere. Since it only happens when you're decelerating - ie not using any fuel - it could be a number of issues.

If you buy fuel from one of the three major oil companys you don't need additives as they are injected into the product during loading at the distribution terminal. As stated previously, Supermarket fuel does not normally contain additives, thats why it used to be cheaper.

This is such an old chestnut, that has been chewed over many times. Last time, on these forums, a couple of tanker drivers came on to say that they delivered the same fuel to various outlets, supermarkets and normal retail outlets. The reason it's cheaper in supermarkets is the same reason that they have any other special offer, simply to attract customers. I have a full bottle of Redex in the garage that I was going to use in an old banger, but got rid of it instead. I'm reluctant to put it into my newish Mondeo, because my instinct is that it would do more harm than good. Modern ECU's are clever little gadgets, and can adjust themselves to whatever fuel is being used, as far as I know, at least up to a point. Why deliberately upset something that is working well? I've always run my Mondeos, petrol that is, on the cheapest grade of unleaded, as per the handbook, and the engines have always been as sweet as a nut, even with well over 100,000 miles, just regular oil changes etc.
