Going from Super Unleaded to Unleaded

When I used the premium fuel I did notice better MPG, but as I don't have a regular pattern of driving I just put it down to coincidence.

Regarding my figures, it does make sense. I'm only saying what comes up on my dashboard. Using Super does seem to give more range, it does keep your engine cleaner and it can improve performance.

How do you know this?

Without pausing to consider if they make the slightest mathematical sense.

You might call it driving like a granny, I call it being sensible. My car, if I having it Auto or Dynamic and throttle the peddle, can see the range drop in numerals of 5 every minute or so. I drive sensibly to conserve petrol because even driving normal can use a lot. It is Audi's higher performance of the standard A3 line, don't forget. It also has Quattro, so it has an All-wheel drive system which uses petrol constantly to power it and is always on.

If this is your way of thinking it sounds like you have bought the wrong car. There is no point in having a performance car with 4WD if your going to be constantly looking at the fuel consumption every time you put your foot down. These cars are not for people who want to "drive sensible". I'm not saying you should drive like an idiot anywhere but they are more for people who want a lot of power and who don't really care how much fuel it uses.

For your next car your probably better off getting a performance diesel car. You will get a combination of power and MPG that you will be happier with.

I can't help what my screen tells me. I don't really know what you want me to say.

Super fuels are more refined and do improve efficiency. Look at the MSE page if you want to see someone else say it.

Don't get me wrong, I accelerate harder when required or when I feel like it, but just because I have a fast car, doesn't mean I have to drive fast all the time. You won't keep your licence. You say it's not built for consumption watching, then why does my car, and even more powerful cars, have Efficient modes you can engage.

I watch my consumption because if I tear around, I'd be at the forecourt most days. Like I said, I said I have an Audi S3, not an Audi R8. I bought the car because I wanted more power when needed, I like the design, I like the sports look, and I like he options than came with it that don't come on the standard models, I like the ride quality and the overall material quality. I haven't bought the 'wrong car'. Everyone should drive sensible, so I don't know why you're peddling a 'fast car drive stupidly' agenda just because you can.

Definitely wouldn't get a 'performance diesel' car (which is a bit of a cliche, because diesels aren't built for performance). Diesel costs more anyway, and is going rapidly out of fashion because of emissions and future diesel taxes. Not a good suggestion.

We are completely getting away from what I was asking, and to be honest, no one has answer it. I don't know why people on here can't answer a question.

OK, let's turn it around. Take the figures on the dash computer as gospel.


Go back and look at the calculations I gave. Tell me where _I've_ gone wrong.

No, but you could look at it and think 'some of these figures must be wrong' before relying on them or posting them on a forum.

My dashboard tells me that I'm achieving 34.7mpg, when I fill the car, zero trip reading and check the mileage when I next fill up I know that I'm actually achieving 29.4mpg.

The figures generated by onboard computers are rarely accurate and it has been pointed out the figures you gave do not make sense which is not that surprising as they are computer generated.


I run a 2.8 Z3 set up for 98/99 so for the last 10 years I've tended to use Tesco 99 it can run on 95 but it takes a few tanks for the ECU to adjust.
