diesel quality!

[JonathanM]

Can't really compare fuel usage based on £20 fill up though, it needs a brim fill, run down, then refill. You've used x litres to cover x miles, then you can workout fuel consumption.


Fuel consumption increases in winter months, so is that the cause of our problems?


And it might have been me who commented on my wagon liking french fuel, and cheap french supermarket fuel at that - it always seems to run better and give better mpg over there.

Hi

I work for Total UK at Warwickshire Oil Terminal at Kingsbury. Our fuel all grades comes in by train from Imingham Refinery Total and Conoco. We also receive fuel by pipeline from UKOP ( United Kingdom Oil Pipelines) which comes from Stanlow Refinery Shell, and MLP ( Main Line Pipelines) Texaco. Tankers loaded at our Terminal include Total, Conoco, BP, Shell, Morrisons, Asda, Sainsbury. The fuel Petrol/Diesel etc all comes from the same storage tanks, the difference being that Total, Conoco, BP and Shell all inject there own specific Additives. After a train or pipeline receipt a sample off the fuel is taken from the the tank and is checked for quality before being released for sale.

cheers chaz, very informative answer, so i suspect from this and all the other ocntributions we may be on the right lines that fuel quality is indeed going down?


my £20 fill up thing is a bit rough i know, but it was no real experiment just my observation of the miles to a regular top up so maybe more acurate than it forst seems, as i allways refill when the light comes on!

so it looks as though you could be right plank.

ps.
and not forgetting how many times its been quoted as running better with svo mix.
WHICH I AGEE ON

I too have found that Shell derv gives more mpg than morrisons have been running 10% used chip oil and find that the engine runs smoother, I am going to try 15%. Any advice on this would be welcome .

For years I've been habitualy using Sainsburys. Cheapest around here.

Got very low one evening and Sainsburys was closed.

Called at local Esso station and filled up. 1p/ltr dearer than Sainsburys at the time.

After a few miles motoring I realised the old girl was smoother and had more torque---quieter too. ( Not like my wife who gets noisier as she talks ).

Now on my fourth Esso fill up.

MPG seems better too. Maybe it's all my imagination ; but if it is then I shall buy dearer and imagine it's cheaper.

One of the problems you may come across that could cause indifferent running , not sure how it affects mpg is the question about whats actually in your fuel.

When it leaves the refinery or storage yes its scientifically mixed with each companies additives to make it smell nicer or whatever added.

One thing that can occur on a regular basis from a retail outlet is petrol in diesel or diesel in petrol.

That occurs because empty tankers after delivering and before refilling have two states. Notionally empty and cleaned empty.

Cleaned empty is just that steamed and dried , notional occurs where a usually dedicated fuel tanker is not cleaned out and a new load is added. It may fill up with diesel but the previous load may have been petrol with the tanker emptied only as far as practicable. That can leave a fair bit in the bottom of a tanker. Perfectly normal practice and the reason you will see a diesel tanker on the road marked up as carrying petrol. The remnants are sufficient to be classified as the higher risk!!!!!! all legit and commonplace.

I guess the turnover and delivery system to each retail outlet will vary and impact.

I was aware of this but never thought much of it until I opened my filler a while back on my 2.7tdi after a diesel fill and got a definite whiff of petrol

Hi just do a search - plenty of threads and plenty of us running 50/50 or even higher.
