Are you all running on Super or 95Ron?
I have an M140i (as well as the upcoming S4) and that has only ever been run on 98-100. But it only does 6k miles a year. the S4 will be doing 20k+ so I think it might have to make do with 95
Not an S4 and driving with a imaginary egg under the pedal:
Not all downhill, mostly a slight uphill then all level, even overtook a car that was doing 40mph. But I will admit hard work to achieve and not strictly real world motoring but the challenge was made.
Its my usual run from the petrol station to home....
Lol, I could not stay with that style of driving, firstly I am not really that bothered with mpg and, with a car like mine, it is really designed for more spirited driving and I easily get bored...I find that pretty amazing then since my wife's little 1.0L Fabia can't even achieve that on the flat doing 40+ mph... Maybe I'll buy her a 2.0T A4 next!
What does it say inside the fuel cap? I'm currently driving a Golf R and it says 97 RON. Using 95 you loose power. I thought my S4 would be the same but maybe Not?I’ve run it on both and never seen any significant difference in economy or power to be honest. I believe the manual states the car is tuned for 95 Ron so there’s no real advantage in terms of economy or power using higher octane. Only benefit might be any cleaning additives or whatever they put in the premium ones...

No more V-power for me thenMine says 95 RON and that 91 can be used with reduced power.

I’m finding this thread fascinating!
I’m currently pondering an S4 order going in and even more so after we did an 800 mike round trip a couple of weeks ago in our current car, b8.5 2.0tdi (190ps) quattro manual Avant, average speed of 58mph over the 800 miles and very sensible driving only managed 42.3mpg! Very disappointing for a diesel on mostly motorway miles!
Now coming on here and seeing people managing these figures with an S4??? I also have a b5 S4 that’s got a mrc stage 1 map which gets sub 20mpg and sometimes single figures but it gets driven properly
So to settle it I’m picking up a brand new S4 demonstrator tomorrow so I can compare it to our current car for the wife’s daily commute, 5 miles from one side of town out the other, current car manages 32-35 average for this trip each day, of the S4 returns the same sort of economy for the daily trip then I’ll take the car the dealer has arriving in 3 weeks time! Luckily they have one the exact spec I want on the boat
Oh and I’m aware with the demo being new the mpg will be a little less than when it’s run in, our a4 was terrible until nearly 10k miles and on its 2 full set of tyres!
When I say through town it’s a steady 30mph round the bypass, it’s a small town and not very busy with no traffic lights etc on her route, I’m just interested to see what it gets and to be honest we’re quite settled on taking the car that’s on the boat in time for Christmas
20s I can live with
Ok so I picked this demo up last night, 40 miles on the clock and now at just under 140 miles, so in that 100 miles of mixed dual carriageway, coastal B road and round town with the odd boat of throttle it is returning a very impressive average of 32mpg! I say impressive as our current a4 2.0 tdi only returned 22-26mpg when it was new until nearer 10k miles!
The car itself is nice enough, maybe a little too refined for an s model for my liking but a nice car never the less, feels more connected to the road than the b8.5 but thanks to the horrendous continental tyres it’s very noisy on certain road surfaces, doesn’t tram line like the 255 tyres did though!
I’m in a predicament now, not sure what to do? All depends on the figures the dealer comes back with but the mpg is good enough for me
