for those interested in this sort of thing, I've now had my Yeti 1.2tsi for 11 years and being somewhat nerdy have kept fill-to-fill fuel consumption records since new. Over the 11 years I've average a very reasonable 41.4 mpg with a best of 47.1mpg. Last week I'd booked a week's holiday in the Peak District but for family reasons the journey was Portsmouth-Hull-Ashbourne and return the following week. Between long stretches of motorway driving and the hills and narrow roads of the Peak District the Yeti's reputation of driving a brick through the air at anything over about 50mph suggested I'd be lucky to see 40mpg. In fact I was surprised to get a genuine 46mpg for the 1,150 miles I did. Which I don't think was at all bad for the types of driving i did and for more than half the miles it was with three adults and all the luggage needed for a week's holiday (i.e. packed to fill every available space). Not a bad result for a petrol engine.

Very respectable. We averaged similar in the last DSG 1.2 we had. I occasionally drive my elderly mum's 2014 Fabia with the same 105bhp engine, and you are right re the aerodynamics as it's regularly doing over 50mpg on the motorway.

After 3 years bar a couple of months mine has averaged 39.5mpg.

 

I regularly run at 120kph/75mph on the motorway (and sometimes a tad more) 

 

Best ever over a full tank was an incredible 49.99mpg (wish I knew why/how!) and worst 32.50

 

Record keeping by Fuelio app.

Over 53,000 miles my 1.2 Tsi DSG Yeti (2017 model) has averaged a true 44.6 MPG. This is based on brim full to brim full fill ups from new. 

Well done but do you drive like a nun?

We ran 1.2TSi Mk2 Octavia and 1.2TSi Yeti at the same time, same platform, same engine.

 

On my commute to work (30 miles each way including 15 miles motorway) the Octavia was 10mpg more economical.  

 

The Yeti really is a brick.

 

Or to put it another way.

 

With 150PS the Yeti manages to reach around 120mph, it's replacement the Karoq around 130mph and the Octavia 140mph.

 

That's aerodynamics for you.

Agreed, it's interesting that the EV makers are spending lots of time getting the CD factors down.

 

Also, to backup what you said, we took our new 170ps Yeti abroad years ago for skiing and it would not go more than 127mph whatever we did - I put it down to the drag around the front wheelarches. The Octavia 190 4x4 estate indicated 145 (couldn't quite crack 150 in Germany).

Not at all, I am not a boy racer (been there, done that) but keep up with traffic flow and cruise at legal limit on motorway. I have been driving for over 50 years and guess with experience comes anticipation of forward road conditions, I think that saves petrol. Switch off stop/start every time but do use premium 97 octane petrol because the Yeti drives more smoothly with it and I proved in my previous Yeti that the extra cost (8p per litre here) is more than recouped in better MPG. So on a cost basis I spend 8p per litre (5% extra) and if you allow for that I guess you can argue I achieve the equivalent of 42.25 MPG - on a price basis compared with someone buying regular 95 octane petrol. But I know that using 95 octane in my previous 1.2 Tsi DSG Yeti dropped the MPG to about 41 MPG and it was not as smooth to drive.

I know it is argued that I am wasting my money buying premium petrol BUT I have the data over 1,000’s of miles to prove otherwise!

...my Impreza hates anything less than 97 RON fuel, so I know what you mean. Tesco Momentum (99) is it's preferred tipple over any other fuel, and I've tried a few

Aha, I knew there had to more to it than you were letting on, tut tut 

 

98 octane is available here in Spain although there not many outlets with it in my particular area so I'd have to make at least a diversions if not a special journeys to get it on a routine basis.

 

The price differential between the cheapest 98 and cheapest 95 in places I could or would reasonably be likely to fill up is at least €0.20c or 13% though so I'd have to improve my mpg to 44.6 or more to make it just technically viable.

 

Might give it a shot for experimentations sake, it is supposed to be beneficial in terms of inlet carbon build up due to direct injection.

 

Something else very pertinent to fuel economy is tyres, not only by make and model but also degree of wear and pressure, each and all of those can have a significant impact on MPG which kinda makes conversations like this interesting but proof of nothing!

Forums are always a good place for airing experiences and recommendations. Sometimes it's worth trying other people's ideas and suggestions - it makes life interesting.

Other peoples experience and ideas are certainly worth considering. In truth my Yeti just drives better with 97+ octane petrol so I would still use it even if the savings were not so clear. The major item which affects fuel consumption is the driver, tyres etc all have an effect but in my experience it is how smoothly and sympathetically you drive that is the biggest influence on MPG.

No argument there!

 

One problem for me is sharing the car with 'er indoors who, bless her, is a good driver but never drives with economy in mind.

In some ways it's a bit of a miracle that I get the mpg that I do!

That's a fight not worth picking! Er Indoors will ALWAYS win. Experience of over 50 years of marriage, happy wife = happy life!
