Just to prove I'm not going mad.

Picture of my fillercap inside:

mine says the same , I used v power for the first few months then changed to tesco's momentum found momentum gave me more miles and felt more responsive.

My Car is a 2007 TFSi and quite clearly shows 95Ron as per the pic

I've not heard of injector problems from using 95Ron. A friend of mine has ran his vRS on 95 from day one as he refuses to pay 7p a litre extra for V-Power.

This (long) thread on the mk5gti might be worth a read:

I have not felt much of a difference between Tesco's Finest and V-power personally. V-power may have had a bit of an edge but that could have been a bit subjective.

However, it ran like a dawg on BP Ultimate compared to the other two - nothing subjective there as there was no doubt in my mind about it.

Perfect excuse to go out in the car

Hey that's true! If I ever get it back that is :'(

Yup as i posted this pic from my vRS.

It also states in my handbook that if you use 95 Ron you may experience less performance.

I have always found my car to run better on 99 (Shell V-Power). I have tried BP Ultimate and Tesco 99 and the car noticeably feels sluggish compared to V-Power. I think a lot of it is down to how the car is run in and how often you use the fuel. My Car started life on 100 Ron fuel (I lived in Germany for the first 14months i owned it and V-Power in the Fatherland is 100 Octane) so seems to like V-Power the best.

I have no doubt that if i ran a couple of tanks of Ultimate or Tesco through it the car would adapt to the fuel. But i try to stick to V-Power wherever i can.

The way I read the picture is it's showing minimum 95 but recommends super! 95 is not classed as super but regular unleaded. TFi can run on 95 but the recommendation is 98ron, the TSi recommendation is 95ron.

Depending culture is how it is defined to the owner.

If you look at a comparison it shows on mine 95 AND on the right hand side it says Unleaded Fuel only.

On the ones others have posted it says 98 (95) and on the right hand side says Super Plus Unleaded.

If 95 was so bad for the car then im sure my mate (who's vRS is 2 months older than mine) would have had problems as he has always ran 95 Ron and has done similar mileage to me (60k+ miles)

My BP Ultimate pump says 98RON IIRC

I checked it doesn't, it says 97RON - it also said £63.00 . . .

Yup BP Ultimate is 97Ron.

If you got BP Ultimate 102 by mistake though that £63 would have been around the £160 mark :o

... but well worth the investment if you fancy trying it .......... I tried it once and it's like having a bigger turbo, the trouble being that once tried you'll want more of it!

The TFI will run on 95ron nobodies saying it doesn’t, but the recommended fuel is 98Ron, I probably averaged out one in four 98/99ron when I had my Mk2 VRS TFI with no problems and I wouldn’t have expected any.

The point I was trying to make is I don't think the 95 fuel would fook up injectors as some people suggest.

The reason TSi engines don't like low octane fuel is that Tsi's operate at high compression (IIRC 10:1 plus turbo boost pressure gives ~ 15:0 effective compression ratio). Low octane fuel suffers from knock - at high compression, the final phase of burn is not controlled but detonates prematurely. This gives rise to "pinking" and "knocking" which apart from sounding bad, can completely eff up the power stroke and worse still has the potential to destroy an engine, melting piston crowns and valves. Fortunately modern ECUs can detect knocking and will adjust the ignition timing and fueling to reduce or stop knocking. Unfortunately that has the side effect of reduced power, economy and smoothness.
