I filled up with £43.00 worth of Tesco's 99 this morning, but without a turbo I don't suppose it will make feck all difference, only too my wallet  :rolleyes:

Doesn't yours need the 98 brew, then?  What does it say on the inside of the fuel filler flap?

VW brochure says 95 RON minimum, just like every other car in the range. I would have thought GTI, ED30 and R32 would all be 98 RON to get the best out of them :undecided:

Yebut - that is just a standard "get-out" clause, I think - for the tight gits that penny pinch at the Asda petrol stations!  :rolleyes:

Aye me too.  But it might just be a turbo or FSI thang - and CCs has neither!  But on my fuel filler flap, if defo says 98 as the preferred, then something like 95 with reduced performance.  I just wondered if CCs .:R32 said the same?

No my flaps say 95, and I thought the R32 had an FSi fuel system ? mind you it is a lazy engine, I mean 250 from a 3.2 is hardly pushing the envelope

Mine says 95 RON is fine on the filler cap. Nothing about reduced performance.

Different to mine. My just says 95 Minimum. I've prob got the wrong sticker on mine after hearing about some of the oddities that comes out the factory.

Maybe the ED30 has to have 98 as it's in a higher state of tune?

No my flaps say 95, and I thought the R32 had an FSi fuel system ?

I too initially thought the 32 had FSI (VW stealers again!!!) - but have subsequently been told it definately does not.  CC, look on your plastic engine cover - if it does have FSI, then those three letters will be adorned on the cover.  Alternativley, remove the cover, and look for the injectors, and more importantly, the ultra high pressure FSI fuel pump.  To id the pumps, look at the pics of the engine in my RS4 thread - there are two pumps, one for each bank, sitting on the red-tops, near the rear RS4 carbon cover.

mind you it is a lazy engine, I mean 250 from a 3.2 is hardly pushing the envelope

Yebut, the 15degree narrow angle VR6 suffers with cooling probs (when tuned), which is why they are in a relatively mild state of tune as standard.  On the Audi A4, and upwards, the 3.2 V6 is actually a 60 degree wide angle vee!

My GTI sticker is exactly like Hurdys.

In my last B6 S6 (non FSI), and my current B7 RS4 (FSI), they both had a sticker saying 98RON, then 95RON (but with something like reduced performance).  I'm too busy ATM to take a piccy - going away actually - so I'm sure my ears will be burning whislt I'm away!  :wink:  :grin:
