Supermarket Diesel. Does it clog injectors ?

[BoroRover]

Reading today that supermarkets will be, "slashing", diesel by 3p by the weekend, there was a claim their diesel is inferior, having additives that clog injectors. Quite apart from the cost of their fuel rose by an average of 11p a litre during April/May, it's hardly a "slash"

It is concerning to read their product may cause problems.

It is welcome though, to read of a reduction, if only for a couple of weeks when it will be back to its former price....or dearer.

I normally use Asda for my diesel. I'm thinking it may be wise to buy elsewhere.

If it did do that wouldn't there be an awful lot of cars broken down....
Isn't fuel made to some sort of "standard" quality?

I would imagine so Nick. I haven't noticed any reduction in performance etc. It just a niggling thing in the back of my mind.

I have never used anything other than "Super Market" fuels, never had a problem And that is in 140k miles and 15 years

Theres always threads popping up by people claiming that supermarket fuel gives them less mpg, runs a little rougher, higher emissions etc etc.

I just put in what is nearer / cheaper or more convenient for myself at the time. The two nearest petrol stations to me are Morrisons and Asda. I would have thought that over the years 70% of my fuel has been from supermarket pumps with no apparent negatives.

If you're concerned about additives or the lack of why not put your own in raising the cetane / octane ratiing as well as claimed lubrication and cleansing properties.

I have started using this stuff of late, not religously every fill up but when I remember.

So called premium fuels from branded petrol stations are about 10p a litre more expensive that their regular fuel, using an additive such as that above reduces that to more like less than 3p a litre more and when used in supermarket fuel rather than branded fuel costs far less than Texaco, BP, Shell etc in general with presumably most if not all of the benefits of their premium fuel.

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)

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.

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.

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!!!

Dave.
