The hesitation mentioned in a couple of posts could be the '06 stutter' if they were on BLT-engined cars (assuming BLTs weren't just fitted to Fabia vRSes???)

Whats the 06 stutter and what are BLT's?

Whats the 06 stutter and what are BLT's?

BLT is the engine code (last of the 1.9 PD130s). Come to think of it, ISTR the Octy II 1.9s only had 105bhp output? Even so, it could still be applicable.

I think this thread highlights a common misunderstanding. There is a difference between meeting and exceeding a specification.

Product A meets the minimum specification, it must work correctly. If not the maker is doing something wrong.

Product B exceeds the minimum specification, it must work correctly. If not the maker is doing something wrong.

Product B may offer benefits over and above product A. The benefits are for the consumer to decide.

In the case of diesel fuel, all fuel must meet the test specification defined by EN590.

If the car doesn't run correctly on fuel that has passed EN590 the car is at fault, not the fuel.

Of course it's possible that the car runs better on a different fuel but no car should have a problem with fuel that passes EN590.

Supermarket (or any) fuel cannot take the car below it's stated performance, else it would not pass EN590 and could not be offered for sale.

Update:

I have it on very good authority that:

1) yes, the stock component is basically the same what ever brand you buy - it is a set standard re engergy content and cetane

2) all diesel contains bio-diesel. This can be of varying quality and origin. It can cause engine components to gum up and leave deposits

3) the additive packs for different brands does vary significantly in the quality of the additives (basically detergents). So much so that an engine using a leading brand, when dismantled was almost spotless inside, whilst a similar engine using a budget brand was found to be very gummed up, sooty and contained a lot of deposits in the combustion chambers.

It seems that the better quality fuels help to burn of or offer cleaner combustion of the bio-diesel part of the fuel by using more advanced detergent packs in the mix.

My source does research into diesel engines at a University for major car manufacturers. I trust him and believe what he says. I'm converted! Long term it is better to use a better brand of fuel. The odd tankful of super market stuff wont do any harm if it is used infrequently.

There you go.

Yes - my problem was the 06 stutter - the reprogram (or whatever they did) improved it but it never went away completely.

Could be opening a can of worms up here, but here goes anyway!

Having a few problems with my vrs at the moment, with various warnings lights, the latest one is a fault with the exhaust pressure sensor, which hopefully skoda will replace under, 'goodwill'

Anyway, i have also spoken to a vw/audi/skoda specialist, and they said some of the problems could be related to what sort/type/grade of fuel that i am putting in the car. was told to generally to avoid 'supermarket fuel' because its basically the 'dregs' of the fuel left from over the big boys, like bp, shell, etc. etc, and they then sell it cheap to the supermarkets.

I always fill up at Morrison’s, { don’t whether that is bp or what}, about 5 years ago i had a tdi mondeo and always used to fill up at Sainsbury’s, but on the odd occasion i would fill up elsewhere, and when i did, the car always did less mpg to the gallon. the guy i spoke to this morning, said that different brands of fuel can also make a big difference to your average mpg's, he also recommended to use shell, it might be dearer, but he also said that it would cause fewer problems, like dpfs, etc.

So my question is, to you guys with diesels, where do you fill up, have you had any problems, that could be, related to the brand of fuel that you use, and has anyone noticed differant mpgs when they use differant brands of fuel ?

Ok, thanks. I was a bit worried but mine is the 2.0 PD 170. I had the 1.9PD 130 in my golf and thought it was a great engine, very smooth. Its still going strong now with nearly 200k on it.

Just to add to this thread...In the past 2 years of owning a Superb 1.9 Tdi,I have experimented with the different brands just to get decent mpg,(was doing 100 miles a day)....I have found BP to be the best.I do everything by the tank full.With BP get 56 mpg,..Jet is 54 mpg,..Sainsbury is 49 mpg,...Tesco is 50 mpg....this was all do while driving to 2000 rpm....Was always told that fuel was fuel...the only difference was the addatives used by the different companies........

Imo this is why its worth paying for good fuel i.e. V Power, because of the superior additives. V-Power wouldn't come from the same refineries as the other brands because its actually a different structure to reg diesel, its less dense, GTL process, lower sulphur content etc.

Less dense means less MPG, though - it really is a case of burning twice as bright for half as long with VPD, which is why I don't bother!
