Seat Leon Cupra Lux 290 - What fuel to use? 95 or 98?
Discussion
Hi all,
I'm waiting for my Leon Cupra to arrive and wanting advice from current owners regarding the fuel they use? I know it can be used on 95, but I'd rather pay the extra amount and use 98 Shell V-Power.
What are everyone's thoughts on this? What do you guy use? Would it be worth it?
Any hints/Recommendations welcome!
Thanks

They’re mapped to run on 95. I ran my Audi’s on super but I know I was wasting my money. I now run my mustang and my wife runs her cupra 300 on 95 because it honestly makes no discernible difference. Any fuel economy improvement would be offset by the increased cost anyway.
They're mapped to run on 98 but will run on 95 "with reduced performance".In my experience, VAG turbo engines are more responsive than most to octane level when tested on a dyno.

Is that what it says on the inside of the cap? If so I stand corrected. In my experience, VAG turbo engines are more responsive than most to octane level when tested on a dyno.
My wife’s car is the front wheel drive so can’t handle it’s 300PS anyway so an ever so slight reduction in power wouldn’t matter.

Owner's manual says "Super 98 / Super 95 (with a slight power loss) ROZ".

Fairly sure the cap says "98 (95)" like most of the higher performance VAG stuff.

Fair enough, I stand corrected then. OP ignore me I’m talking bOwner's manual says "Super 98 / Super 95 (with a slight power loss) ROZ".
ks. Mercifully my mustang being a naturally aspirated yank tank is built to run on dog st fuel!Edit: I wonder how slight the loss is?

Premium fuels are like premium tyres, or deciding between OEM brake pads or Halfords ones.
For me, on a shed, I'll use whatever is cheapest/most convenient. On a car I care about I'll use OEM / premium parts where I can. No different with fuel.

I only use Tesco 99 in mine.
Miles cheaper than V-power and better than shell 95
Only issue is, there isn't any where close for the Tesco fuel that does the 99, whereas, Shell V-Power is a trip down the road....So probs worth going to shell just for being close to me and on route to work as well.Miles cheaper than V-power and better than shell 95
My MY14 Cupra 280 flap said minimum 95 on it. I ran mine at Stage 2 for 4 years which ran APR Stage 2 high torque file which required 98+ Ron.
We did some logging one day on RR with Momentum 99 in the tank, at no point did I tell the tuner it had M99 in the tank, after a few runs he looked at all the graphs, not just the peak power/torque graph and said have you got Momentum99 in the tank? I was like yeh how can you tell, VCDS showed a lot of timing being pulled.
A few days later after a cycle of Nitro+ (when it was called Nitro+) we did the same again and the difference in timing was night and day, plus it made peak 12bhp more, both days temperatures were similar as well.
I did have to run it with 95 in it one day with the 98+ map in place, I just didn't drive it hard, filled it up with 99 again asap.
As said above if you don't care about the car then do what ever is easier and cheapest, if you care then put decent fuel in it. I also changed the oil every 5k in it.

Mine has only ever used V power since they day it was collected (It's Sob by the way)
A friend of mine has a pre FL 290 and Dynod it on the day of purchase with crap fuel and then a few days later with V power around 10bhp difference)
Ah Sob! Should have asked you already! V Power it is!A friend of mine has a pre FL 290 and Dynod it on the day of purchase with crap fuel and then a few days later with V power around 10bhp difference)
Thanks for the input everyone.
