Try to run the Cupra on Tesco Momentum, but I don't fret if I have to use 95 octane (usually in the depths of Wales) as it's usually only a tankful. Did the same with previous LCR. I reckoned I could feel a slight difference in acceleration when really nailing it, but it could just be a placebo effect.
Seat recommend 97 as that is what the performance figures were probably obtained with, however the engine - thanks to all the sensors etc - will adjust itself and run fine on 95, with a slight drop in performance. If there was any likelihood of engine issues, somewhere (fuel flap or manual) it'd say 'DO NOT USE 95' . So it's 'safe' to use either. Your engine, your car, your cash, your choice. Fuel in the UK is certainly a lot better than that elsewhere,in some countries you'd be better off pi55ing in the tank......
as for turbo cooling....... even before having a turbo engined car,if I'd given it the full beans then either a period of slow running or idling was always required, remember engines were a lot more fragile back then (Dolomite Sprint - ask your dad ! ) as the thought of turning off a red hot engine and leaving it marinating in its own juices was not the done thing.when turbocharged engines came along, a cool down period was mandatory.( I used to cook bacon on the turbo of one of my company cars on a run, Dover was always good for a hot butty!)
I realise with advances in modern engines all this is probably not necessary but, out of habit, I still do. In any case, our house is a good 15-20 minute run through 30mph limited urban streets from the nearest 70/60/50 limited road, so that's usually the cool down sorted.
stop/start?its a pita and as soon as I find someone who can disable it, I'll do so. Not for engine protection reasons,just because I don't like it.

it is a pain but for the time being, as you may've found out, if you're judicious with the brake pedal, ie holding just enough pressure to prevent the car rolling, the stop/start won't activate

It can be done by VCDS, I've done it on my dads Golf, and it works a treat.
Ours is manual but I know what you mean.it is a pain but for the time being, as you may've found out, if you're judicious with the brake pedal, ie holding just enough pressure to prevent the car rolling, the stop/start won't activate
I just need to find some kind soul near Brum who can do it......
ah, sorry, i couldn't remember which transmission you had
i take it the stop/start activates through the clutch pedal? if it does i can empathise with your dislike of the system because that was the activation process in my previous car.

I've only ever run my Leon on Tesco momentum 99.
I look at it as follows;
I'm not mithered about any alleged performance improvement claims regarding super unleaded fuels, but I am interested in the benefits of the extra cleaning properties to the fuel system components that the super unleaded fuels give.
I could buy ordinary unleaded and then chuck a bottle of fuel additive in, but what's the point when the fuel you can buy does the same thing.
So for sake of a couple of pence if you can care for the engine internals and prolong the life of the car & keep it sweet, it's a couple of pence worth paying

Careful, I've been told by my technician that such practice can cause premature wear on dsg boxes.it is a pain but for the time being, as you may've found out, if you're judicious with the brake pedal, ie holding just enough pressure to prevent the car rolling, the stop/start won't activate
Try it out, leave your car in D on a traffic light and watch the rpms while barely touching the brake, just enough to stop the car. Do the same with the brake properly pressed and notice the rpms. It's the car declutching.
The car goes into neutral with a light touch of the brake. When you let go of the brake you can feel the gear initiate.
Not mine, if I touch the brake lightly it stays in gear. I have to properly press the brake for it to disengage.

This is my first petrol car for 6 years, previously had 3 Ford Kuga's all diesel, I found out very early on with Kuga no 1 that Supermarket diesel made the engine rattle and was a bit hesitant. I changed to BP Ultimate diesel and the engines on all 3 Kuga's ran a lot quieter and smoother. My wife and daughter have Ford Fiesta'a which only ever have Tesco Momentum in them and I find that they run better with no flat spots etc so my FR 150 ACT is also using Tesco Momentum and runs very well, I had a recent fairly fast trip back from Southampton on the weekend and although the car has only done 820 miles the computer was showing an average of 45.8 mpg which I am very happy with. The slight extra cost with premium fuel is nothing if the car runs better and hopefully will help in the long run by keeping the engine running at it's peak
It says in the manual that light pressing of the brake pedal prevents the engine stopping. I don't recall it saying anything about this practice causing premature gearbox wear.
thanks for the warning, i'll have a look on the next drive. only noticed rpm drop at a standstill in Sport mode but that was only after shifting the lever from D to N.
Yea I mean I really have no intention of scaremongering or anything, just be aware of how far down you have to brake for the clutch pack to disengage vs how lightly you have to press for the start stop not to kick in.
I personally hate the start stop and I seriously believe it is hazardous when you have to enter traffic fast from a standstill, but that's just me
Depends which ones your talking about, if you take esso extreme as am example, the only real difference between that and normal esso diesel is the extreme has twice the amount of detergents it

Tried the v-power & BP Ultimate a couple of times and noticed no difference in the way the car performed over Tesco Momentum. Only difference with Shell & BP was price lol
Also helps collecting the Tesco club card points & getting a few pence of the cost of a litre every few fill up's, so the Momentum ends up costing same as ordinary unleaded
That's a brilliant return from the 1.4 ACT engine.
I have a daily 14 mile round trip commute and a bit of mixed driving at weekends.
I normally see mid to high 30's....anywhere from 35 to 38mpg per the MFD reading on the daily commute. Leave for work every morning at 07:20 & return at 16:00, so traffic isn't too bad.
Most I've seen on the MFD was 57.4mpg on a trip to Edinburgh, admittedly this was doing 60mph in cruise on the motorway, but getting from Manchester to Edinburgh & return on 1 tank of fuel was good going from a petrol 1.4Tsi.

no problem, im not viewing it as scaremongering, if im doing something wrong it's best to know about itYea I mean I really have no intention of scaremongering or anything, just be aware of how far down you have to brake for the clutch pack to disengage vs how lightly you have to press for the start stop not to kick in.

i always disable stop/start in unpredictable traffic or when it doesn't feel appropriate to avoid that initial hesitation before moving off again.anyway .. back to the original topic
