Which 98RON fuel for GTI Polo

[Grabman]

But what I can confirm is this...
In my previous Polo GTI with APR Stage I (V2, 98 octane mapping), if I filled the car up with Caltex Vortex 98, it would idle roughly on cold start. So rough that the car would stutter as if it were about to stall. I live within 1 minute of a Caltex (which was a pilot site for the Woolworths "pay at pump" credit cards, for which I was a pilot user) and I shop at Woolworths and therefore used to get 10c off all the time (being a Pilot tester for the system). After having this idling issue I swapped to BP Ultimate and it went away..

ok, not running a GTI but have same issue with my TSI, filled up with Vortex on a country drive and it runs rough at start of day etc, hadn't noticed this prior to the Vortex. Will drop some Ultimate in on way home, have about 1/2 a tank left and see if it starts to clear itself.

thanks for the idea, I was thinking it might be ECU issue.

cheers

You could always chuck in a bottle of octane boost, if that helps, you know it's good 'ol dodgy supermarket ownered co-branded fuel...

As your stock tune is designed to be more forgiving on bad fuels, you will notice more difference once chipped.

I like BP in the 1.8T, a little more peak power

about half way through a tank of V-power now and its aint too bad, it feels rather touchy on the throttle and seems to run in a raw type of way to redline than the previous fuel. Just got my fuel card with BP, so will be running it on BP Ultimate from here on in after this tank.
