Been running 95 as well with no problems and car hasn't complained.

I prefer to take the advice given by Skoda, 98+ or 95 if it is not available.

I would assume that long term use of 95 may cause burnt valves due to pre-ignition.

I think it would be unwise to ignore the manufacturers advice.

Yeah, I filled up a tank with V-Power today, wallet took a pounding at nearly £50, but it should last a while.

The range said 305 miles, but hasn't changed for about 20 miles.

On a vented tank and driving very carefully i've had 510miles out my Boc. Day to day on a vented tank I get around 420. But.. give it a bit and i've had 280

Cost me £53.50 this morning...you've must have cheaper V-Power! :|

And do you need full power this time of the year?

126.9p I think it were. Was 129 at my local shell though, just so happened the cheaper garage was on the way to where I was going.

As said...Ive not noticed any difference putting higher octane fuel in...So why pay more??

It has 95 on the filler cap afterall

There seem to be be two big assumptions here;

1. That you should be able to feel the difference straight away

2. That 95RON is as good as 97RON because Skoda say the car will run on it

The first assumption is wrong because the low RON fuel will cause pinking so the ECU will retard the ignition so the engine runs smoothly. It will do this over the course of a tankful or so, say 400-500 miles. For most people this is a very long time and they won't notice it. The ECU has parameters it can vary so it learns to help you drive the way you want to. If you want to drive economically, it will modify engine parameters to help that. If you want power it will modify parameters to do that as well. It does this faster, over maybe 5-10 hours of driving. These two factors make it almost impossible to notice anything over a couple of days driving for most people. You really need to reset the ECU after each fill-up and a rolling road to measure it properly. Some car magazines have reported as much as an extra 50bhp (BMW M3) using 98RON petrol over 95RON.

The second assumption is wrong because you can't tell the difference between 165bhp and 180bhp most of the time without a stopwatch, but that's the sort of power drop you're looking at with 95RON petrol. The car will only develop full power with 97RON petrol. It says it in the owners manual (which I know no-one ever reads).

So, yes, there will be a power benefit to running V-Power petrol, but you probably won't notice it unless you're the kind of driver that 'makes progress' as Roadcraft puts it.

If the filler cap is the same as the TFSI Octy's then it will have 98(95). The 95 does not refer to RON but a different unit of measure.

At the end of the day the car will run on 95 RON fuel but you bought a performance car, hopefully to use some of that performance

If not choose your car based on the fuel it runs on in which case a vRS is probably off the shopping list.

And do you need full power this time of the year?

No but i'd like my engine to last thanks I turned my remap off because I don’t need the power. I still fill up with v-power though.

Way I look at it, it may cost you £3/4 more per fill but you DO get more mileage and your engine will thank you for it. If you use Shell and get your v-power card you'll get double points. I got £10 this month rather than £5. Which is free money in my book as I’d be using shell anyhow.

I can't find them now but have you seen the pictures of the engine which used standard fuel compared to v-power.. The different warrants the £4 extra alone!! The v-powered engine's cylinders looked pretty much new.

With regards to power, my car made 194BHP using v-power in stock form. A friends run on the same rollers on 95ron made 178BHP.. ok it has slightly less mileage but there was certainly a difference.

I've been on several RR days, I found a 7bhp increase an shell V-power deisel, compaired to stock deisel.....

but to be honest with the high miles I do (103k now, gonna keep to 200k) I'm more interested in the cleaning properties.....
