Supermarket Diesel. Does it clog injectors ?
 

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:shrug: 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.

Yes - Mon and Ron specs

Hale and Pace characters weren’t they?

There was something about this on the One Show this week. They said that all petrol comes from just a handful of manufacturers and the specification is the same for all brands and supermarkets buying power, lower margins together with getting you in the store to buy your groceries is the reasons they are cheaper. They interviewed QA inspectors who said it was all the same and manufacturer management.

They then went on to say that then the branded suppliers may then put their own additives in to clean the engine, burn more efficiently etc.

I have used both branded and supermarket and found on the diesel that BP was a little smoother than Sainsburys and a lot smoother than Morrisons which I stopped using and gave about 3 more mpg. But if I used Sainsburys and Redex the results were similar and works out cheaper.

On petrol I run my Dolomite on Sainsburys Super Unleaded with a lead and petrol stabiliser additive and it runs well. Dolomite engines vary, some can run on unleaded but mine cant. However when I have used Esso, BP etc it runs much better and has more power. My Volvo recommends using Super Unleaded for better performance and economy and standard unleaded is ok to use. I use both but find that if I use Sainsburys unleaded I get the bad egg smell. Had every thing checked out in case and was told it was the fuel. Their super unleaded, which is in now in the tank is better the car runs and gives better economy by a couple of mpg but still gets the odd whiff of bad eggs. If I use BP from around the corner the standard unleaded runs as well as the Sainsburys super and costs about the same or a little more and no smells so that's what I use mainly. The Super duper stuff they sell does improve on this and I can tell its in but the cost puts me off it.

I remember talking to a tanker driver many years ago. He advised me that there are only a couple of refineries; the same fuel goes into all the tankers, and they all deliver it to each other anyway.
