Supermarket fuel

We had a fuel injector go on the car after a visit to France in 2014.  There's a part of me that blames French supermarket fuel.

I have a friend whose car always puts the engine management light on in French France 

Sorry to resurrect the Dodo but I was really interested to look at the BP Ultima web site. To all those that believe they get better or worse fuel consumption from different fuels, please take a look at the video. I will try and summarise:

A full tank of fuel  (which tank, which fuel?) gives you 391 miles with a dirty engine. You could get an extra 21 miles with a clean engine. One way to get a clean engine is to use Ultima for a prolonged period. Saving about 5% mpg, extra cost of Ultima, well, that would be about 5%.

So, there you have it. Using the most expensive fuel available and assuming you have dirty injectors you might make a saving roughly equivalent to the additional cost (Depending on road condition, driving style etc. - it says) after prolonged use. Oh, but you will have a "clean" engine.

Correction - That would be BP Ultimate.

When I bought my car in 2012 it displayed all the signs of injector loom failure, spoke to a few Passat owners on the owners group, they told me without being asked to stop using supermarket fuel. 3 and half years later running on nothing but Shell (40,000 miles) and the symptoms never returned. 

The basic product is the same, it's the aditive package for each retailer that differs as well as storage quality, infact I had someone on this very group get very abusive to me over this subject so just Google it ;)

Only if you are buying the premium version of the fuel, otherwise there is no difference in the additives! And on a full tank of fuel, the additive equates to about a spoonful. 

You cannot state it was because you have stopped using supermarket fuel as you have undertaken no comparative testing, all you have is weak anecdotal evidence that it stopped, coincident with using identical fuel from another source. 

My self and a few others have tried it, since using Jet I now get 10-15 m.p.g. more than I did using morrisons/asda.

When getting low m.p.g. with my punto the garage mecanics told me to use branded fuel, I never noticed any differance with petrol but D.E.R.V. is a different kettle of fish

10-15 m.p.g????

Dakota, see what the experts say, read it, it makes sense.
