I'm getting 7.4 for the first 10000ks in our Superb (50% open road) on almost exclusively 95 from woolworths (caltex). I tried Vortex for 3 fills and I didn't think it made enough of a difference to pay the extra and wait for the 98RON pump (I'm regional).

I found with the VRS (which definitely did like a diet of 98RON) that if you didn't keep the 98 up to it, you lost any benefit. But I didn't really have a preference after moving regionally Whatever was convenient - though I did blacklist a United after a bad belly of fuel - thankfully no damage just run badly. Got it serviced early because of that.
