Diesel Fuel

[Yorkie]

Hi.
Thanks for the comments gents. Some interesting points.
I agree that all Fuel sold is made to a minimum standard but just wonder if that standard is well.....minimum if you get my meaning.
My Wife's Astra is a plain old 1.6 Petrol and if I put Tesco in it I can nearly guarantee an Oxygen Sensor fault will show. Maybe that is a fault with the Car.

I also noted a few problems that had been confined to Supermarket Fuel. This led to them having to pay out compensation for damage an example here.

If all fuel was identical should we have seen all outlets affected and not just the Supermarkets?

My Jeep has the Merc' 3.0CRD in it and I am reluctant to feed it Supermarket stuff and it is getting V-Power at the moment.
Thanks.
Nick.

V power is a waste of money, I have a bmw 730 msport and use normal diesel in that, for my shootin truck range rover p38 i make bio diesel out of used cooking oil and never had a problem, it costs 25 p ltr
cheers

Just to correct a few point here:

although the the diesel may be the same, the finished product is not!

you see the diesel you buy from the supermarket has added bio diesel...just read the pumps next time you are there.

sometimes is is as much as 15% bio.

now you may not notice that! however it is a bare fact that biodiesel does not have the same energy content as normals diesel. This in turn will see reduced performance from your car.

this may be reduced power, efficiency or decreased mpg. It DOES have an effect.
just ask anyone that uses 100% biodiesel....it's all too familiar and we'll proven in both science and practice.

the fact is you may not notice it for many different reasons! but either way it is the truth.
No delusions just the cold hard facts.


i bet those saying don't delude yourself didn't actually realise they are buying biodiesel mixed with diesel!

I have been making bio diesel and using it for years, properly made and tested bio diesel works in any diesel engine, only reason I dont use it in my newer bmw is it would void the waranty, the car manufacturers wont spend the money to test their cars with bio when diesel engines were invented they only had bio diesel

 

[long_range_rob]

Indeed scubadog is right

I knew a chap who ran his Surf on veg oil but had to mix one litre of white spirit to fifteen of veg oil to give it more oomph. Worked well but every time he drove up at the range I had a sudden desire for a bag of chips.

i used to make it too...although I agree (almost) his don't do too well on it and some fuel lines and o rings rot with it.
i used to run his on it, it's never as clean as derv due to glycerol and of course it will always drop some solids out during very cold weather (hence why people add petrol in winter months)

I use supermarket diesel most of the time, I use my 90 horsepower car for emergency responding and have no problems at all, just loose 50 or so miles a tank if do fair amount of jobs and miles hot but then I am usually down a gear for the trip for more control and acceleration so I am not unhappy. When I use Esso I have not noticed any better mpg. When I was in Norfolk on various holidays I thought the gauge had bust as got almost 15 mpg more compared to flogging round the Peak District

Diesels will happily run on kerosene , heating oil , paraffin , veg oil , olive oil ,avtur and a load of other stuff , in my experience they all need an additional lube chucking in (except veg & olive) and power output is always LOWER.

 

[Devil_Bri]

How much more expensive is bp ultimate diesel etc, compared to supermarket cheaper stuff ?
Say 5p a litre more ?
60 litre tank = £3 more per tank for a fuel which will give you more mpg and better for the engine etc etc
Personally i buy it every other fill, as i feel its a "no brainer" and worth the extra £3

 

[sauer]

I ran my hilux surf on
a 70%\30% veg to diesel mix & yes a wee bit lower on power but not hugely , noticeable , but at 50p ish a litre it was worth it .....Costco sells in 20l. Containers
Craved a fish supper if behind it tho

[deeangeo]

It all comes from the same place at the termial

Yup it certainly does
But there may be benefits from running a full tank of premium fuel through your car every 5/6 weeks or so... the premium stuff does clean out the injectors and often better for your car than after market 'cleaning stuff' that may affect catalytic converters.

 

[Leon]

It's correct most starts life at the same source however... Premium branded fuels have additive packs blended in just before delivery to the forecourts, same sorts of technologies it's only the amounts that vary. The ISO standard only applies to the raw form Cleanliness/Sulphur/FAME values not the additive pack. I remember seeing a W10 Audi with two separate fuel systems for each bank, it had cameras fitted into the combustion chamber on each side wired to monitors in the head rests... You could clearly see the differences when running on different fuels.

In Scotland all supermarket fuel is imported from Rotterdam or Zeebrugge by Ross Chemicals Ltd. Itis bought at the cheapest price in Europe then shipped to storeage tanks in Grangemouth. It barely passes UK specs. Whereas BP made fuels exceed minimum limits. BP, Shell and Esso up here is fresher and made here and is days old not months old.

If you suspect fuel does not meet the minimum required standards you can report it to trading standards , they have to look into it (and they will love you for it ) , the same if you suspect short measure from a petrol station or elsewhere.

 

[Yorkie]

If indeed it is all the same stuff how is it that the only people affected by the silicon contamination that led to payouts for damage were the supermarkets? Surely the branded fuels would have been contaminated too? I am not saying anyone is wrong just asking the question.

I noted that Tesco are part owners of Greenrgy that imports Fuel. I think Red Dot may have something.

I buy branded and add mineral 2 stroke scooter oil at a percentage of 200:1 (so if I fill up 40lts I add 200ml of oil) I do this to add back the sulphur that has been removed in the last few years, less knocking/smoother acceleration/more mpg

Its to be hoped you dont have a cat or DPF fitted

The 2-stroke oil will keep the diesel engine clean, as it burnes cleaner as the diesel itself.
In other words, the 2-stroke oil has a much lower ash-content as diesel, when burned. This proven fact delays the DPF (diesel particulate (soot) filter) to clogg, and the "burn free" process of the DPF will be much less.

Try returning your car under warranty with your miracle additive in the fuel line , youd soon be shown the door , I`d also guess youve not stripped many scooter / moped engines , the cheap scooter oil used does not burn clean at all and the exhausts usually put on a couple of kilos in unburnt oil and residue, the only 2T oil Ive seen burn cleanish is that used in race engines such as MX and enduro , even then the mufflers clog.

Read this report , conclusion is DPF life is shortened and power goes down 2-Stroke Oil In Diesel – A Technical Study

 

[longhair]

supermarket fuel is cheaper because its a mix of regular and bio diesel,it burns hotter which is why people have injector problems.personally only use bp diesel for the extra 50p a tank and piece of mind
