Google it - there are many!

However, our Mondeo has been left outside for a week with about 2 gall of Asda derv in it ( bought 4 weeks ago).

-5 when we got in it after it de iced itself this morning, fired up first time.

On reading all the forums about diesel and the new Ford engines, I shall try to keep to Shell (which is my cheapest local anyway).

There are a lot of sites which discuss it, I am looking for some independent evidence that substantiates the facts which doesn't seem to exist so is all the evidence anecdotal?

surely the supermarkets cant have different fuel

ive not seen many tescos oil rigs around the world lol
last time i heard morrisons and asda used esso

Discussed many times- Different additives.

It's the same base fuel at the fuel depot. When it is metered into the tanker for delivery to the petrol station, additives are mixed into the tanker as well, to make it "Shell" or "BP", or "Tesco". They are different. I don't know if there is another system that can mix as it's pumped out of the tanker if it's a multi drop, ie shell followed by tesco for instance. I'm sure Psidoc can fill us in on this.

This is another bit I can't undersatnd though, people quote additives but these are put in as part of the refining process and then shipped off to storage and distribution depots such as Buncefield which don't have blending facilties and don't have a supermarkets only tank. So I go back to my original request, can anybody produce any evidence (apart from anecdotal) to support the argument?

Having worked with liquid dosing units I would be interested if this is the answer as there has always been an extra mixing process after liquids I have dosed and this cannot happen in a tanker.

and as posted by PSI i believe (works for a refinery)

He clearly states that the same diesel is pumped into tankers with the exception of a couple of companies that add their additive. He also mentions than the big mainstream fuel companies don't all add their additives.

Its marketing and nothing more.

Supermarket fuel will be 99% identicle to mainstream fuels imo. If it wasn't up to scratch it wouldn't be allowed to be sold, simple

I haven't seen any scientific proof that supermarket fuels give worse mpg or are not up to scratch. I'm certainly not going to take the word of someone on a forum claiming they got 3mpg less on sainsburys diesel when their are so many variables in play. Driving the same route, same time of day, day in day out does not constitute to an accurate representation in any way shape or form.

The weather plays a huge part in how well a vehicle will perform, from humidity to ambient air temp, it all affects the way the ECU controls the fueling etc.

If i saw "real proof" i.e scientific experiments then maybe i'd be more open minded but those that believe shell/BP has superior fuels are playing right into that companies hands.

Diesel is diesel simple as.

Can't comment on how simple diesel is, but you remember when tesco added silicone to their diesel by accident? It may have affected asda and morrisons as well from memory, but certainly wasn't any of the top names.
Diesel isn't just diesel. Some is different.

You don't blend, you inject into the filling pipe, so it mixes as it fills.

How Mikey ??

Because shell say they put in additives. What are these so called additives. Cleaning agents i suppose that probably do f all anyway.

It like shell claim you can get up to 1 litre extra per tank using their fuel. Woopy fu*ky doo is all i can say.
