Supermarket Fuel vs Premium Diesel

[Bailey 15]

Who only uses premium diesel rather than ordinary diesel?
Any difference do you think ?

Who don’t buy their fuel from supermarkets ?

Just a thought as recovery guy said he wouldn’t touch supermarkets fuel

At present I always use premium diesel as A= it is only 1c dearer than the cheap stuff where I buy &
B) it is far & away the cheapest fuel in the area. It is just a standalone ,serve yourself 2 pump place That have been popping up over the last few years.

they aren’t driving Euro 5 or 6 spec diesels…

why would you?

Egr valves are no guide to engine problems. Early ones might have been but now they are made out of internal plastic & they then add water cooling to try & stop the rubbish melting.
When I bought this van a new egr had just been fitted. It threw a fault after 500miles. Reset & it went on for 6000 miles until I returned when it promptly stuck open as the plastic had melted. new one fitted under guarantee. That lasted 11 months & same thing happened. I then deleted it along with the insides of the catalytic converter.

But another fuel delivery driver in this very thread said in effect that with the exception of Shell it's only ever the 'premium' fuels that have the additives. To say that base diesel that fully meets the internationally agreed specification and for which 99% or more engines have been designed to run on is somehow 'inferior' is simply untrue unless you are prepared to always pay out for the premium versions at inflated prices. Yes highly tuned engines in performance cars generally need a higher octane petrol, but for the other 99.9% of everyday vehicles, you may as well replace the engine with a steam boiler and engine, and burn the cash.

Your body will still function to some degree on McDonald’s, fries, crisps, cream buns and white bread, but it will function much better on nuts, seeds, avocados, rye bread, sweet potatoes, watermelon and fruit

I think you are right if you were talking about the bodies exhaust system

No one seems to mention additives... I use to use ARCHOIL in al my diesel vehicles being MOTORHOME, VW TRANSPORTER, MERCEDES... it's now been super seeded by OILSYN, it comes in a 1ltr very easy to use plastic container, the recommended mixture 25mm to 25 ltrs etc, that's 1000ltrs to 1ltr, the costings are £25 but there's sometimes promotions on with 20% discount that's £20 that's 2p per litre... Iv'e been buying additives for many years, and i purchase mine from a company called POWER ENHANCER and there's a chappy called ANDY very Knowledgeable, have a read up on the benefits of using OILSYN... (red bull for the tank)

I haven’t used Supermarket fuel for around 6 yrs, as my last motor a Nissan Pathfinder hated it, it would run rough and on at least 2 occasions it needed a flush. I have been lucky in getting a Esso fuel card when I bought the van so I get 4p a ltr discount and apart from a Nox sensor issue in the van it’s run very smooth for 64000miles in 5 years

It's all biodiesel of some form, you can't buy anything else at the pump. It's what the E10 stands for... 10%

Never put E10 in your diesel tank, Only use B7.

I fill up with Premium diesel every third fill, reason is they have additives in the diesel fuel, which break down deposits like soot, carbon, and gum, and this works out cheaper than buying Fuel System Cleaners, I add Forte Advanced Formula Diesel Treatment bottle of Forte Advanced Formula Diesel Treatment once a year, just to give it a cleaning boost, on very rear occasions a forecourt tank maybe nearly empty, and with a faulty gauge, and can feed water from the bottom to your tank, but it is rear.

I buy fuel where ever it is cheaper, Fuel in supermarket forecourts is the same as on any forecourt, most fuel are from the same Refinery, like that at Prax Lindsey Oil Refinery in Immingham. and forecourts are regulated by the same laws & regulations, Each diesel fuel has a specific type i.e. B7 (Diesel), B10 (New diesel type), XTL (Synthetic Diesel) The same markings are used all of Europe.

Just remember, don't believe all the fake tales you may hear about fuel, as long as you use B7 in a diesel engine, don't store for long periods without taking it for a run, and when you do, give it a thrashing for at least 20 minutes to burn off the soot, if you have a CAT, then most likely needs 30 minutes to reach temperature to burn off.

Oh no it wouldn't.................................... I have a nut allergy!

Besides that, in one case we are talking about an engineered machine, and the other a a living being.

Regardless it’s what you put inside something that determines how it functions, regardless of whether it’s a person or a machine. It’s the same principle re-fuelling a machine or a person, that’s why athletes, tennis players etc etc have nutritionists. Do you think the likes of Novak Djokovic or top athletes eat garbage?

Yes it will .You won't live longer it will just feel longer

But going back to vehicles, our old Rover 90 ran very happily to over 250000 miles on the equivalent of two star leaded petrol 88 RON. I wouldn't have dreamt of putting 4 star in. The user manual said it would run on anything above 85RON IIRC. With an engineering background myself, I trust the design engineers to give me better advice than all the rumours and snake oil salesmen that want to lighten my pocket further. Plus as I mentioned, when Trading Standards did lab testing of supermarket fuels to the other outlets, they could detect no difference except the 'freshness' of the fuel' as throughput in the supermarket was higher.

You’ll live a lot longer on average it’s a scientific fact, you might not be as happy but you’ll live longer

I use supermarket fuel all the time, with the occasional injector cleaner added. The only vehicle I particularly use super in is a classic car, which would have been designed for 5 star. I also use an octane booster and valve seat protection in that one.

An interesting observation as on the fuel side of things, you get less for your money buying fuel when it’s warm.

Is it density of air (warm vs cold) youre driving through being thinner providing better fuel efficiency? No idea?

Edit: I’ve googled and warmer weather = better fuel economy!

Presumably as cold air is denser the engine management lobs more fuel in.

Yep cold damp air = more fuel = bigger bang!

What about the electric vehicle debate, is Norweb electric better than Scottish Power or is cheap off rate better for the vehicle? Discuss! It has about the same conclusion as the past 5 pages!
