The reason I ask is I picked up the car and the dealer put a full tank of BP/Shell unleaded in. Just normal no special types.Since using the tank dry I have reverted back to my local morrisons petrol station. :whistle: and probably physiological but thought it didn't feel quite as responsive.. :cry:
Any people have any thoughts on the quality of Morrisons / Asda / Sainsburys and the supermarkets petrol?
aposed to the BP/ esso/ shell etc.. APART FROM THE EXTRA PRICE.. :grin:
Thanks chris.

I always use Shell (Diesel), there's not that much difference in price between the Supermarkets but you get peace of mind... There always these stories of fuel not up to the standards of Shell and BP...
-
Usually Shell v power nitro+, but sometimes have to slum it with Esso super unleaded, as the nearest shell garage is 7 miles away. Never tried supermarket fuel.
probably physiological but thought it didn't feel quite as responsive.. :cry:
Maybe the honeymoon period is a already wearing off :grin:

hah hope not booth! :sad: just you do hear all these stories and the latest being about that corn and the government upping the percentage that is allowed. there is a few esso and shell near me so might give them a try!

yerh, people moan on about well its 1p higher etc which let be honest is **** all. Going to try shell i think!

Unlike the EA113 engine, I thought the EA888 engine as found in the MK6 GTI was tuned to run on 95 ron.
I use the regular stuff from my local Jet garage, I tried a couple of tanks of V-Power but got no change in fuel consumption and could not feel any increase in performance, so went back to (cheaper) regular.
-
I use Vpower as much as possible, my Mrs had problems in her Mini GP using asda petrol, started showing a fault with her knock sensor. Guy at the dealer reckoned it was due to cheap fuel not being refined as much as the bigger company's but whether it really makes a difference in not so sure. Since she stopped using asda fuel the fault has returned.

It is, and that's what's specified on the label of the fuel filler cap, unlike the mk5 which is 98 ron.
Still gonna stick with the good stuff though :wink:

I notice a huge difference personally using Shell especially the Nitro+ or whatever it is now.
TDI just doesn't feel quite as pokey on Tesco fuel, MPG is always more on Nitro and it saved me £8.32 on two identical journeys in the Clio over Tesco fuel after taking account the extra cost and extra MPG.

Due to being asked a previous similar question, I asked a friend with a doctorate and also a degree in Chemical Engineering/ currently working at a major UK refinery to find out answers to some such questions and this is the reply, summarised by me (I'm neither a chemical engineer, an engineer, a scientist or a mechanic and therefore it is summarised in my words, in good faith and any disagreement with the content, I won’t challenge):
* There is a difference between branded and supermarket fuel.
** The refinery produces fuel which meets all of the necessary specifications/regulations.
*** Then, when, for example a major branded tanker arrives at the refinery, in addition to loading up with the fuel, they add their own secret mix of additives to the fuel. These additives differ between the branded companies and is guarded as to the ingredients. The additives are designed to clean the engine as it runs so as to prevent problems over a long period of time. Apparently, the additive really does work and is not a gimmick.
**** Supermarket fuel, on the other hand, does not necessarily come from a local refinery. Apparently, it can arrive from far afield including mainland Europe, if they can get it at a better price. It will in any event meet all of the necessary specifications/requirements; however will not necessarily contain the additives. It does not damage your car it just means that, for example, valves could get more deposit build ups over a long period of time.
***** The other issue is the difference between basic and enhanced fuels, as one example Shell Vpower. This is considered to be very good indeed as; for example, the petrol burns cleaner and might well result in a smoother acceleration/ better performance experience from the car. It is a purer fuel. You should not notice any difference in performance in an ‘ordinary car’, but in performance cars it does make a difference. However, as it burns cleaner, it helps keep your engine cleaner and so, even for an ordinary car, it is considered to be worth putting a tankful of branded enhanced fuel in now and again.
So, that info, along with my previous logic and what I have learnt from threads like this means that reference so called 'normal cars', I will continue to fuel with supermarket fuel (using time to time tanks of enhanced branded fuel); & for so called performance engines, I will continue to use enhanced branded fuel.

As mentioned before in tuned cars I think it does make a difference, a friend of mine with a tuned Scooby will not run on supermarket fuel, he was running low and put a tenner in the car wouldn't idle having to keep the revs up to stop it stalling, and then it wouldn't pull away (it was remapped with nitro+ in tho)
In our golfs tho Ive just changed over to the nitro+ from just Morrison petrol and I think I am getting better mpg, before I wouldn't get over 40mpg but today tank and half of the stuff later sitting at 65 on the motorway with 2 bikes on the roof got 44
Id say give it ago, its only a fiver more for a full tank (my local nitro+ is 10p a litre more then Morrison) make your own mind up as im planned for remap soon im gonna be sticking with the nitro+
-
That was my logic. Single figure GBP extra to fill a tank up. Not too concerned about mpg and couldn't swear I notice any improved performance but I do feel (might be in my head) that the cars run more velvet smooth on VPower nitro+ ... And based on my friend's knowledgeable insight, it seems worth an extra couple of pounds per fill up to me but many swear that supermarket fuel is no different and as mentioned, nobody suggests supermarket fuel will damage the car anyway.

i see you done your research mate! yerh think i am going to give the shell a go for a while and chop and change between morrisons and shell. thanks for the advice buddy!

On my last car (mk1 Seat Leon LCR) I always put in Shell Vpower as the engine was rated to run with higher RON petrol. Since getting my mk6 GTD I've been thinking is it worth putting in the Diesel equivalent as it technically doesnt need it.
I ended up putting it in anyway, because as I see it, over the course of one tank its only a little bit more, and that extra would only end up being spend on a coffee/drink/sandwich anyway, so why not.
I might give 'normal' diesel a try to see if there is any difference.
