Just picked up my TSI 95 yesterday and took her to the garage filled her up with unleaded then got home and realised when I opened the fuel flap again its sayin to use super unleaded, I'm not knowledgeable whatsoever on the differences but wondered if anyone can tell me have I done damage filling up with regular unleaded? Will I need to fill up with super unleaded from here on in?

95 Tsi Fuel?

I'd imagine very few people bother to fill their sub-1400 SEAT with anything other than 95 Standard Unleaded.
The car's engine/fueling computer (ECU) will auto-adjust to compensate for whatever grade petrol it's being fed,
from a range of around 91 dodgy 'furniture polish' still served-up in some far-flung corners of the world, right
upto 100+ octane boosted. This does'nt mean that it will give the best results at either of those extremes, but it
will still run.
As to advice for typical UK use, your engine will thank you for filling it with decent Shell or BP every so often, even
if only 95 grade, rather than too much of the cheapest supermarket fuel.

I think that car makers should take care when including descriptions like "Super" when related to petrol, it is possible that "Super" in one country is 95 RON and in other's like UK, it is 98/99 RON.
As far as I know, for quite a few years now, with the exceptions of specialist performance cars, all new cars sold in EU must be able to run on normal UL which means 94/95 RON and are probably tested using that fuel, but that bit means nothings until the newer regs are in place, though maybe still a fudge job to con us and others.

In theory you will get slightly better results using 98/99 instead of 95, as certainly all petrol engines,
no matter how modest or high-tech prefer to run on higher-rated fuel.
IME on a range of different cars/vans, a typical engine primarily set-up to run on 95, (as most UK road
cars are) typically shows upto 3% improvement in economy and as stated by previous poster such a
small gain in performance that it's hard to even detect whilst driving.
Because of this, it rarely makes financial sense to go for 98/99 if the vehicle is recommended for 95.
Best value for your money compromise I've found is to fill-up alternately with cheapest 95 you can find,
followed by a tank of 95 Shell/BP, which should keep your engine and wallet happy enough.
What I actually do these days is fill-up using only Shell 95 when possible, but using their 'Drivers Club'
loyalty card which brings the price down overall to almost supermarket levels anyway.
If I get 'caught short' a long way from a Shell, then I just top-up with BP or whatever is most convenient
and certainly don't fret about it.

In the UK I fill the car up with 95 RON fuel (90% of time) from all proper fuel stations except supermarkets (exception is Tesco Momentum 99). Eg...I would fill at Shell, BP, Esso, JET, Texcaco. When the fuel prices are lower (which is very rarely these days) I might give it a tankful of Esso 97 or Shell/Momentum 99 RON fuel. Does it give more power? Maybe 2-3 bhp more, but I cannot feel it. Does it give more mpg? According to the fuel computer (my journeys are somewhat consistent) yes it does by 3-4 mpg, but once again, I did not compare with the amount of litres going into my car. Calculations between extra cost of higher RON fuel and more range per tank, still shows 95RON is still marginally more economical. Might be the car thinking (like humans), expensive 'higher quality' wine or champagne must be better, therefore yes...97/99 RONit gives more mpg. Only Esso 97 gives me a 'smoother/less stuttery' engine from low revs, this I can 100% confirm.
Had a flatmate who only filled with Supermarket diesel for a good 10k miles worth in a 1.5Dci Clio. Tank would last 9 days tops (she only does, to work and back)...persuaded her to use Shell Vpower Nitro Plus Diesel, she scoffed, protested, argued, she's not rich etc...but gave in anyway, cause I wouldn't shut up. 1st full tank of good stuff, lasted 10 days. 2nd tank of good stuff lasted 11 days. Calculations, was cheaper to run the good stuff, as it would give 60 miles more! So it depends, perhaps engine just got a nice clean from the good stuff...like descaling a kettle.
