Fuelling my GT

[gizzywizzy]

Where I live we only have the one petrol station and it provides 95ron only.  I've been to the nearest town 30 minutes away but have even had a problem getting 98ron there.

My question is will I be doing irrepairable damage to my car? or will it be ok?

So far in 6 months ownership the car has only covered 1600 miles so am hoping the engine is still sound.

Lol, no I've not been drinking I'm using a laptop on my lap and it slipped when I was putting GTI in hence post reads GT.

Someone who has a mk6 GTI near me says I have to put in 98ron or higher to get performance from the car, I have only been able to put 95ron in that is why I was asking. 

Look I am female!! I fill it up and off it goes (hopefully) I'm just checking against what I've been told. OK?

Sorry i did not realise you were a woman ,the mk6 gti engine is set up to run on 95 ron,so tell you friend he knows nothing there was quite along post on this a while back,if you read the inside of the fuel cap cover it says 95 ron.Save yourself some money and stick to 95

I remember that post.

Unfortunately I don't agree with the 'results'.


My car runs much better, is smoother and more economical with 99.

I filled up with 95 for the first 2000 miles or so (as that's what is on the filler cap flap). Then I tried 99, MUCH better.

No amount of 'but it's set up for 95' will convince me otherwise.
Just try it for yourselves.


By the way Gizzy you won't harm your car in any way at all by using 95. You'll just get a little less performance/economy.

Even the mk5 which was officially set up for 98 ron will run quite happily on 95 with no damage whatsoever except that as stated fuel economy and performance will suffer.

The way the FSI technology works means it will always work better with higher octane fuel.  It stays in lean burn mode for longer and delivers more power when you push the pedal.

The mk6's have been designed to give the published fuel economy and performance on 95 as opposed to the mk5 engines which delivered the published power and economy on 98.

95 RON is fine for the MKVI GTI. 98 or 99 RON fuel will run better, giving slightly economy/performance.

No amount of 'but it's set up for 95' will convince me otherwise.

It's not set-up specifically for 95 - that's the whole point of FSI - it'll run on any unleaded over 95, but better on a higher octane rated fuel. 

I've tried regular supermarket brews (95), BP Ultimate 97 (?), V-Power (99) and Tesco Super (99) for extended periods. All were fine, but 99 fuels noticeably better than others. I can't feel a difference between V-power or Tesco Super.

Thanks all for your comments and advice.

If I can, I will at some point try 98 or higher just to compare.

It'll take 1-2 tankfulls of the jungle juice for the ECU to adapt the FSI to the better performance.

I'd recommend Tesco Super, purely because you can collect clubcard points on the fuel and/or get 5p off a litre if you spend upwards of £50 in store!

or better still actually use the car - under 300miles/month is doing more damage than whatever fuel you are using.
