Is there anyone who actually knows the truth about branded fuels and supermarket ones?
All brands load from the same depot, during loading, the tanker driver adds the additives. all branded fuel has additives, supermkt fuel does not.
The only difference is the 'super' fuels like Excellium, these are made from the LPG gas byproduct of the refining process. Being made from gas makes them 'cleaner' ie free of microscopic particles, they claim to increase injector life & do give better fuel consumption but not enough to cancel out their extra cost.
does anyone who use these "off the shelf" additives such as Millers , Wynns or whatever think they do any good ? never used them myself , never have done.just wonder what happens to the fuel system when you start dislodging deposits by using these cleaning agents ?
do you get clogged fuel filters or problems with blocked injectors for a time ?

This Diesel malarkey is all brand new to me, my biggest worry has been using a green hose rather than the black! first couple of times I picked a Diesel only pump just to be on the safe side
Trouble is it's so long between fill ups now you forget again
I've just put another £30 worth of Asda Diesel in, the previous £30 was also from Asda and that lasted near on three weeks, that to me is mind boggling economy at 35mpg for the worst type driving, the old V6 used to use that a week doing the same things...must have been doing about 10 to the gallon?
...Forte' is supposed to be the trade's choice. Allegedly only on sale to the trade but Ive seen it on sale in plenty of places, expensive at £15 a bottle.
After suffering a fuel pump 'melt-down' on my diesel, and the main volvo dealer and my own mechanic telling me it was due to the crap fuel I'd been using I now use Optimax or V-Power. If I have to use a cheaper/supermarket fuel was advised to double dose the fuel tank with Millers additive. The last set of diagnositics and then a new fuel pump cost me a fortune, getting to the 'Well, is the car worth it' kinda thing. It's just not worth the risk when I can just as easily fill up with better grade fuel.

use wynns injector cleaner for petrol twice a year roughly (more on the old proton) dont know if it makes any difference but the car feels better at that time. generally run it though after a service
If the driver is putting additives into the tanker, doesn't that mean you get less fuel for your money and more additive. Therefore, If you get less fuel for your litre, you cannot possibly be getting more miles from the smaller litre. The only explaination I can see for better mpg is that because the fuel cost you more, you drive more economically.
Interesting Big Al, the Shells and BPs are often referred to as "premium brands", as was the case in recent media coverage for the supermarket price war.
Proof of the pudding is in the eating, and I wont be going back to Tesco fuel as I dont want the performance deficit.
It does seem to make a difference. I regularly drive 400-odd miles from Cheshire to Ross-shire in the Highlands to my relatives house, involving a stop for refueling around mid way.
If I fill up at this end using Shell (which is the cheapest but further away, approx 4-5miles) I've noticed that when I stop to top up (used to be Cumbernauld, but that service station has been pulled down, so now a little further away, on the far side of Sterling) I am not topping up as much, I maybe have a quarter of a tank left.
The last time I went recently, I filled up at this end at Tescos (which is no cheaper unless you get the vouchers, I don't spend enough to get any so pay full whack- unfair!) and had to stop at Sterling Services as the gauge was on empty and I had to pay a whacking £1.12 a litre.
However, the expensive stuff at Sterling seemed to last well into the week running about as well as getting me to my destination.
I don't discriminate between supermarket or branded diesel although reading this thread perhaps I should. I tend to use Sainsbury's diesel for Nectar points and BP otherwise again for the same reason. Currently in my area all filling stations both branded and supermarket are selling diesel at 108.9 so it'll be BP I'll be going to.
The only time I've ever noticed any significant difference with performance has been when I've accidentally filled up with BP Ultimate or Shell's equivelant but at between 4 and 5 pence a litre more I won't be doing that routinely.
I know both a filling station proprietor and a garage owner and both say that supermarket petrol should not be used to the exclusion of all others.
I find it hard to understand how HM Customs and Excise as well as Trading Standards would allow supermarkets to sell an inferior product which would put the welfare of peoples' engines at risk. Surely supermarket fuels must meet basic standards.........
