Since my local Shell station has closed I tend to get petrol at Tesco - sometimes with 5p off per litre, sometimes not.

I was low on fuel the other day and filled up, for some reason with their 99 octane stuff, which I hadn't tried before. 129 per litre I think.

The claims they make on the website are amazing ! About 20% extra MPG.

Hasn't worked on my car yet though. Still 27 MPG on the short trips I do, which has been the norm over the cold weather recently.

I wonder if the advertising standards people have been told about this ?

Shell do a similar claim with their V power

If you do only short trip's i doubt you are going to see much difference, but the high octaine fuel is normaly better for your motor.
if on other hand you did a long trip with no stop start driving you might see a gain if you drive normally.

As far as I can see Tesco don't actually make such a claim.

If you still have it in your tank you might want to try resetting the ECU. Not something I'd normally suggest, but when changing fuel you never know....

If you check out the Tesco Fuel Report they do claim an 18.5% average increase over all of the vehicles tested.

The report written by thorneymotorsport.co.uk?

I don't recall them being a subsiduary of Tesco. They are some tuning outfit.

The graph on the page I linked to does show 20% gains in MPG for some cars, and it is on the official Tesco website.  The front page of the Momentum website is much more modest though, claiming it may save money.

I have tried an ECU reset however, it made no difference at all.

p.s. Tesco sponsor Thornley Motorsport, if that is relevant.

My view is that the "cheaper" brands don't have the full range of additives in the fuel and may, therefore, must have an effect on the inner workings of the engine.

From the day I bought my car I've normally used Shell but on the odd occasion when supermarkets give vouchers for pence off I've used non Shell.  

On these ocassions I've noticed a difference in the way the car performs, for the worst, and when I've refilled with Shell notice a better performance.

I think that's very relevant. Automatically rules them out as being independant as far as I'm concerened.

Over here the Shell stations are controlled by Coles (one of 2 major supermarket chains we have) and most of the Caltex outlets are controlled by Woollworths (the other major supermarket chain). Both give 4c/litre off with purchases of over $30 at the supermarket (8c through January).
Their latest trick is to drop the price of milk (2L) and bread (baked on site) to $2 each - permanently but at the same time fuel has gone through the roof, to between $1.35 and $1.48/L so there are suggestions the one thing is subsidising the other.

Between the supermarkets, fuel outlets and banks ------Grrrr!

I get where you are coming from Trev.. It is clear what they are trying to do ...

Price their competitors out of the market with Bread & milk and then when they have no competitors they will ramp it back up higher
