fsi owners - super unleaded, do you ??

Supermarket fuel has no additive I can tell you that much.
Its fair enough to say it all comes from the same tap sure,but when Loading I can confirm additives are blended in with the fuel depending on what you say your taking from the Terminal.
Only specialist fuels such as V power,Bp Super petrol are only available from certain refinaries adding transport costs to the pence per litre.
Bp's super diesel is just an additive unlike its petrol sibling.

I think 102 petrol is only available in certain garages throughout the country, normally in areas served by bp refinaries.

I had a conversation along these lines with my local indy VW/Audi/Seat garage last month. He said that the FSI engine does not need the "super" unleaded fuels available but to use the standard unleaded at places like BP, Shell etc NOT supermarkets as despite recent statements that all fuels are the same the ones at supermarkets are inferior. This should apparently mean you get more miles to the gallon and should prevent sluggishness, carbon build up etc.

Not done enough miles since to be able to draw comparisons but this seems a nice mid ground between forking out for more expensive fuel or going with the cheapest!

I'm not sure where your garage man gets his theory from, but I'm pretty sure supermarkets get their supply from the same main suppliers across the country. E.g. Greenergy supplies Sainsbury and Tesco (if not more) where location permitts. When your garage man say 'inferior', is there anything specific? I will be very tempted to say that is all speculation with not a trace of evidence. Lab result showed they all meet the stated Octane rating, I doubt he has done lab test on the effects of the additives from major brands nor has he commissioned an independent research on the mpg difference using supermarket fuel. As I always say, people *think* something is instantly better as soon as you put a brand label and price premium on it.
 
What he said to me was based on a lot of experience in particular with the FSI engine, he had owned a couple in his time not to mention the ones he has worked on, said he found they ran more smoothly and a few more miles to the gallon depending on where you get the fuel. I didn't ask for the advice and he was not on commission from Shell (as far as I am aware)! Whilst I appreciate that they have to meet a standard rating and he obviously hasn't conducted a broad investigation into the situation if I am near both a supermarket and another garage I know which one I will choose!

I only use super unleaded from either BP or Shell preferrable but Esso at a push.

I used super diesel in my old car and regular and think that the upgraded stuff does make a slight difference in running but then again it may just ease the mind in thinking it does?!? :eek:
 
Not sure if they have changed the rules but this statement about the 1.6 fsi engine is from Audi literature published in April 2002
The use of Super Plus unleaded (98 RON) is recommended. 95 RON can be used with a minimal reduction in performance and no adverse effects. If neither 98 or 95 RON is available, regular unleaded, at least 91 RON can be used as an emergency measure.
Performance data and fuel consumption values have been calculated using Super Plus (98 RON) fuel.

interesting info to know if I ever come unstuck. Had a couple of times, pulled into a service station and no 98 fuel available. Cheers Spike. :)

I have an FSI and can definately tell the difference if I run 95 ron fuel.
I normally use a mix of JS 97 Ron and Tesco 99. My preference is for V-power when I have the chance.
Without talking detergents etc which may stave off long term problems on the more premium fuels, I can say that the grunt and responsiveness of these engines is influenced greatly by using 97+Ron fuel.
 
Im with you CHB the FSI is a modern engine and I get more responsive power on expensive petrol and MPG is slightly better, not much but if it makes the car run better short term surely long term will be helped. You pay your money and you make your choice I guess. If I had my crappy old Renault still I would put the cheapest I could find in it as that thing was awful and no matter what I put in it it still ran like a bag of bones so I didn't care.
