Supermarket Diesel

[Dick Cheeseburger]

I think this is where a load the non information comes from........the bloke is a mechanic so he has a valid opinion on the chemistry of fuel??

 

Its mainly guess work and urban myth

Whilst I'm aware he spouts a load of double-standard shiz on a regular basis, I do wonder whether there's something in it. Mrs TW is adamant that her VAGTIDY pulls harder when she's filled up with BP, as opposed to Tesco's urine version. She drives a load of miles, and does a full tank refuel every time as well, something which I should, but still don't do. Eternal student mode or something.

Morrison's LPG has got lumps in it.

[DodgeRover]

LPG cut off pressures are a joke, depending on where I fuel up I can get an extra 20l in from empty.

That's with the vehicle level as well, I'm aware it should be 80% fill but some cut off way before that. I know one place has dropped their pressure to give the expensive pump an easier life.

I'm going to get my own home tank when we have somewhere with space.

 

Can't say I've noticed any difference in the quantity of heavy ends getting left in the vapouriser though no matter where I've fuelled up for a few months.

That's a neat trick, where is this place and how did they drop the pressure so they could make less money from every LPG fill?  Usually liquid is pumped and the pressure is related only to temperature as in PV/T GCSE  Physics.  Mine doesn't have a vaporisor so lumps from Morrisons LPG nevre get collected.

[Alfamale]

might just be me but found Sainsbury's ok but Morrisons and Asda is shite. That was in the Alfa Brera though which was a fussy bugger at the best of times. BMW runs fine on almost anything with no variation in MPG. I was told that car ECUs can make a big difference with some having a wider tolerance to fuel qualities and able to adapt better.

We had to go rescue the punters from about £400k's worth of broken DAF-powered Van Hool Astromega in Aviemore last month after the driver necked it with supermarket diesel. Tank drain, new injectors and pump at a cost of £eyewatering.

 

Modern DAF engines seem particularly fussy, having had issues with our DAF powered Bovas we also don't run supermarket diesel either unless it's an absolute necessity when drivers are instructed to only put enough in to get it to either a Shell, BP, Gulf or Esso servo.

 

I never use supermarket fuel in my cars 'cos I shop at Aldi and they don't have pez stations.

Liquid is pumped but has to go in at a minimum pressure to overcome the non return valve in your multivalve, otherwise you could fill like the Americans with simply an inverted propane bottle and a pipe with the appropriate connectors - no pump required.

Fill from there is slower now but as they have a pretty much continous stream of regular customers I guess they loose much less putting in maybe 5l less on an average sized tank fill rather than selling nothing at all for 3 days while they get an engineer to fit a new pump and having to deal with upset customers.

They had 2 pumps fail within the space of 6 months, the last one has been on over 2 years now

Just googled Van Hool Astromega, that's a smart looking big coach. 

[Richard]

When I was running on gas I found that no two pumps would fill to the same level. It's also when I realised just how inconveniently placed most supermarket filling stations are.

 

It was a few years ago now but I reckoned on approximately 50% chance of finding a working pump.

Surely they would have a case against the supermarket for selling fuel that was not fit for purpose?

[Richard]

They would just say that their fuel meets the standards and it's not their fault the bus can't run on standard fuel.

 

Even though I do believe that no good can come of using supermarket fuel (or supermarket food) I'm surprised that it's poor enough quality to need the misfuel procedure if it's used.

[mrcitroen]

I don't think there is anything wrong with Supermarket fuel. If there was, loads of cars would be stranded at the roadside with AA Fuel Assist in attendance.

 

What I think the issue is that as more people use Supermarket fuel than branded, you are more likely to hear about dodgy fuel issues from those filling at supermarkets.

 

Having said that, one of my colleagues fills up in Esso 9times out of 10. He has had 2 dodgy tankfuls over a 3 year period. One in Morrisons and another in Tesco. He now only uses premium.

 

I fill up with Shell standard as it is more convenient to me and I can be in and out quicker than going to Tesco.

 

When I bought my 159, the service manager told me not to run on Supermarket. Reason being that all or most, 2.4 159's in with running issues the EGR valves were gummed up prematurely. Coincidence, I'm not sure.

 

There, I have contradicted myself! But I still think Supermarket fuel is most likely OK on the vast majority of cars!

It's more modern and powerful diesels that suffer with supermarkets fuel... We cover from Stockton on tees to Berwick-upon-Tweed for aa rac and green flag.... We see one or two a day with issues and 2 or 3 a day needing fuel drains

All that poor quality derv would be ideal for the tractors or other Perkins powered stuff, I assume there's a fair few people in the queue for it already?

[Richard]

I think drained fuel now counts as waste and has to be disposed of in an approved fashion. The guy who drained a full tank of petrol out of my Transit sad they used to send contaminated fuel to a tank driving experience place but they weren't allowed to any more.

scrap car diesel Runs the ceos tractors and farm equipment..... All the petrol we remove from scrap cars is filtered three stages and sold back to us staff at 60p a litre

 

All drained fuel on misfuels is hmrc monitored and disposed

Most goes to disposal and we have to advise hmrc how much we drain and if was duty paid fuel

Where's it go from the scrapyard I wonder?

[Squire_Dawson]

If the duty has been paid once over then HMRC should be keeping their noses out?

[worldofceri]

I expect it's more to do with preventing fresh fuel being falsely described as contaminated, thereby avoiding any tax.

[SiC]

I think it goes the same place as used engine oil. That I believe is repurposed for use in industrial applications like blast furnaces, cement kilns and making bitumen.

[willswitchengage]

Does the 5% biofuel element (or whatever the figure is) get mixed at the supplier or is it mixed at the pump?

[EssDeeWon]

I never buy supermarket fuel, no real reason other than the local supermarket pez station always has a massive queue cos 2p saving or whatever it is, whilst the big BP station is like 'pick a pump', any one you want sir.  I might pay an extra few pence each time I fill up but then i'd probably spend that in fuel sitting in a queue at Tesco's watching people fanny and fart arse around, and I get very grumpy at things like that.

[Parky]

I generally use the local Sainsburys but will Bung in an occasional tank of Shell V-Power as they car does feel a little perkier running on that. Probably my imagination.

 

However I can say fuel quality made a big difference to my old Picanto. It only had a small tank anyway and I struggled to get 300 miles from a tank of supermarket shiz. When using BP Ultimate I was suddenly getting 330 miles from a tank and it performed better. Very sensitive to octane rating that little car.

 

Not as much as my ex's Pug 106. It used to pink badly under load using 95 octane fuel but when I pointed this out "I didn't know what I was talking about as her Dad says it's fine" - because her dads zero knowledge trumped mine obviously. On 98 Octane it didn't pink funnily enough.

 

Thing to remember is the supermarkets don't refine their own product. There isn't a Tesco Oil refinery any more than there is a Tesco light bulb factory. It's all coming from the same place.

 

Remember the silicon in the fuel a few years back? The wrong additive went in the wrong storage tank and it buggered a load of lambda sensors. if I remember rightly it affected more than one supermarkets fuel supply

[conkerman]

Not quite. Tescos supplier bought a cargo that was contaminated with materials from electronics manufacturing. I was a fules chemist for nearly 15 years and generally use the big boys product as the supermarket product often has less Effective additive packages. Bio component choice can have an effect on fuel lubricity also. Although Geography is my main selection criteria.

I was caught short in the van on Monday morning and filled up at Tesco for the first time in years. Within a few miles the "water in fuel" light came on. Coincidence?

[dieselnutjob]

My uncle once drove a bin lorry so he knows about these things an he said all truck drivers carry their own cans of additive in case they fill from a supermarket pump they mix some in.  He gave me a jerry can of additive and recommended 1L of additive for every 5L of Supermarket wanky diesel an he said I'd get about 20% improvement.   I dunno what a  20% is but the Focus doesn't need to be filled so often so its true. Bloody wanky supermarket rip - offs tin foil hat wearing daily mail readers.

 

err, if you put 1L of additive per 5L of fuel then you now have 20% more fuel so, which might be why your would get 20% improvement.....

 

The Jag TDVI has a particulate filter which can be problematic so I tend to waste money on the Ultimate / Optimax whatever.  I just think that if a fuel makes less smoke then the DPF will not have to work so hard to clean it up.

[twosmoke300]

I find it hard to believe that supermarket fuel killed the injectors etc on that coach straight away . The only way it could do that is if it was petrol or contaminated with huge amounts of water .

The particulate filter was about the only thing that didn't go wrong on my Jaaaag TDVi - never used bollockomax, often used supermarket fuel.
