It appears we have finally discovered a failing in Master Brian - his ears and possibly other senses are not so finely tuned as one might have expected. :D

Ahh.. but what type of electricity is it? If it is nuclear generated you will get less mpg in your greenmobile than if it is generated using wind power.

Should that be miles per amp/hour?:}:D:shrug:

A useful link MSS. I used to be involved in several oil distribution terminals including two with refineries alongside, albiet over 25 years ago. Intially the first major supermarket to sell petrol and diesel bought fuel on the spot market which was then imported into the UK for their exclusive use, this situation didn't last long, ultimately the supermarkets would draw out of the same stock as some of the major fuel companies. The only difference would be at the point the road tankers were loaded at the terminal if it was for a supermarket no additives were injected into the load whereas for the major oil companies their respective additive would be added. I only purchase petrol or diesel from a petrol company and add Millers to diesel and Redex to petrol, it's down to personal choice and as I don't use supermarket fuel can't make a comparison

As my experience is 25 years ago and a lot may have changed since then and fully understand why anyone doing a high mileage would go for the cheapest fuel available as its so expensive now. Being fortunate enough that I can cycle to work my total annual mileage in all cars is no more than 6000.

One tip I will offer is if I see a tanker delivering to a petrol station I won't fill up there right after as any sediment and water at the bottom of the storage tank is intially stirred up by the discharge and needs time to settle.

In one word No.

Years back, when my dad was alive, he used to drive for Fina (a name from the past that the younger generation will probably not have heard of), at a small depot in Kingsnorth, near Hoo in Kent.

They used to draw fuel at the BP refinery on the Isle of Grain. Along with Fina, from what I recall dad said, all major brands drew their fuel from there. Recall hearing stories from neighbours talking to him, stating that the 'old Prefect or Consul would only run on Shell, where another's Cresta would only run on BP. You don't hear that conversation theses days!!!

Bringing this up to date, the same conversation would now be Mr Green's Nissan Leaf runs better on SSE electric, where as next door, Mr Jones gets a better charge and range on Eon power!!!

I have near enough always used supermarket fuel in the ZT, although it is petrol, and have used their diesel in the E350. That said, when chatting to them about fuels, the independent Mercedes garage that services it did say that there are less additives in supermarket fuel than in premium brands like Esso etc. Never personally had a problem though.

As a footnote, with regards to diesel and fuel prices, there used to be a 1 / 2p difference, but now up to 10p or more in some cases.

Greedy wholesalers / retailers I suppose robbing the motorist once again!!! :shrug:

Badditives - Biodiesel
 

:Yes, but.................something can go wrong

To borrow a saying used by a learned and respected member, "the twoof is out there" (at least I think that's what he said)

http://www.mycleandiesel.com/pages/Biodiesel.aspx

There was a huge and well reported incidence of bad biodiesel getting to the pumps about 6 years ago. it affected whole fleets of company cars.

Things are obviously better now, but using diesel with biodiesel additives is like playing Russian roulette - albeit with a very large chamber. I've got the bullet a couple of times.:shrug:

Remember when we would put tigers in our tanks. I found this on an old VHS tape some years ago and felt it worth preserving.

Never believe simple, absolute, few word answers. They are invariably wrong.
