Hello there. 

I have a 2016 1.4 tsi 150 since 2 week.

 

Overhall i am very happy with the car but i am not sure petrol is for me

 

On eco mode, while driving like my granny , being Almost all the  time  in 6th gear  it seems i can t get  more than 660 km with a full tank 

 

I did  not took a 150 ps  to be in  6th gear at 70 all the  time. I knew it would not be as efficient as my  old diesel (1000 km range while driving without any regard for fuel efficiency) but it s like  i just can  t use 10% of the  power i bought without it having thé fuel  efficiency of a middle size motorcyle. (Some even do better)

 

I do 30km road twice a day  to go to work(and coming back)

70% is outer  urban  road and the  last is in  thé city. 

 

I wanted to go petrol  as it is way smoother and i was fearing of dpf issue due to not doing enough mileage but now i feel  like  i did  the  wrong choice. 

 

Is my car performing normaly?

Have you tried in normal mode instead of eco. I know I can get better consumption in normal than in eco mode in my car and it’s a better drive.

You will never get the same economy from a petrol car compared to diesel, just drive the car and enjoy it.

@Nny  Does the 5 year old car have nice new spark plugs fitted set at the correct gap and a clear air filter fitted?

Just drive it normally and in the gear required and see how it is without being in ECO.

 

If you drove 410 miles / 660 km,

how many litres is used out of that full tank is it 45 litres, 50 litres or just how much used from brimming to refilling?

 

I would be expecting near to 450 miles / 724 km from 45 litres of 95 ron unleaded used., or better if just a driver in the car.

Easily near 800 km for 50 litres if the weather is not that cold.

I’d second that about normal mode. My 1.4 gets better economy in normal and sport than it does in eco mode, I personally find it’s nicer to drive in normal mode as well, so just leave it on that. There’s a link to my fuelly mpg tracker in my signature.

Mine has consistently returned around 40 mpg (apparently approx 7.1 litres/100km), I don’t thrash it, but I don’t hang around and don’t try to get extra mpg. It gets what it gets.
 I love Diesel engines and used to make my living repairing them, but the emissions systems now are garbage. They have to eat their own sh#t with egr systems, dpf’s are a con - they have to literally burn diesel on a regular basis to turn soot into ash !! Ad blue is another complication/cost which is a sticking plaster to get Diesel through another decade.

I wouldn't get hung up on how far you're getting per tank compared to what you got in your diesel. 

The tank itself is quite small in comparison in the 1.4 TSi, it's something I noticed soon after I got my 1.4. I was thinking that I'm getting very little range on a fill, but then realised how little it was costing to fill anyway so I took a look at the specs to see the volume of the tank itself. I think it was 10/15 litres smaller than my previous diesel, plus with the petrol being a bit less economical, it initially seemed it was drinking petrol.

We get at least 450 miles from a full tank in our 1.4TSI, and neither of us are gentle drivers!

I get around 420 miles with approx. 4 to 6 litres left in the tank - this is mainly commuting mileage in built-up areas. Pretty happy with that. 500 miles pretty easily achieved on motorway in past. 

I'm also getting about 420/450 miles per tank with a mixed commute of 36 miles a day with 20 miles of motorway.

 

I swapped a 1.6 diesel Honda Civic which could easily do 60mpg without much effort, I even achieved nearly 80mpg driving very carefully. Do I miss it, not at all. the Octavia 1.4TSI DSG, is a great car.

 

Average MPG for my commute is around 42 mpg

I’ve just bought a 1.5 TSI to replace a 1.6 TDI taxi and I know I won’t get the same economy but I don’t care. I’m in the car for 10 hours a day and I’m fed up with the noise, working the gearbox and all the other diesel stuff like DPF and smell. 
 

Can’t wait to start in the petrol car. 

OK

After further test it seems to get better. No clue why. Only fun thing that the  first 1/3 of the  tank seems seems to last longer than the  2 others. 

Getting rid of the  eco mode definitly helped too. That s very  odd

In 45 years of owning cars I've never had one where the fuel gauge was linear, they've all dropped much more slowly in the first third/half than the rest.

On mine the first half tank seems to take ages where as the 2nd half seems to go much quicker.

I think this is mainly to do with the shape of the fuel tank, also you tend to get a few litres up into the filler tube if brimming the tank, which will account for a few extra miles.

It could be the fuel tank shape but I don't  think so.

I read an article at least a couple of years back where an unnamed Ford engineer confirmed it was standard practice across the industry to give drivers good vibes to think they had covered a good distance on half a tank.

Same as the water temperature gauge does not move from its standard normal  position when it has warmed up. It will only register higher temps if there is something really wrong and then you have got to act.

The water temperature does vary (within acceptable operating temperatures) in daily driving but they chose not to show it, because some drivers panic at the slightest (within norms) rise and head off needlessly to the garage. 

On a run we can get about 500km off the first indicated half tank but usually about 380km off the second half tank before being urged to refill (usually about 48 litres).

You can fill the tank to the point that the fuel gauge shows you have a full tank.  Then you can keep putting in fuel, maybe another 5 litres or more.  There is not then FULL plus more fuel in  showing on the gauge  and that extra fuel in gets used before the Guage / needle moves.

Have you tried driving with the current MPG display activated, so you can see how economically your driving at any given time?

I've found with my 2L Gen 3B engine, I can get silly economy with VERY light throttle use at city speeds, but much more than a feather touch on the throttle and MPG drops dramatically. I can't always use this technique in any kind of traffic because it results in infuriatingly slow acceleration, but just pootling about at 30MPH can give surprisingly high instantaneous economy, returning about 40MPG as a trip MPG for short city journeys, which I think is pretty good. I'd expect the 1.5 to be a fair bit better.

I previously drove diesels for many years, and got used to being able to be fairly heavy with the throttle without much of an MPG penalty. (I quite miss that at times, TBH.) The petrol car is way more sensitive to heavier throttle use, but it's an interesting challenge to eke out more MPG with light throttle use.

Driving on ECO mode is less economical under a lot of circumstances for me, because the engine idles on lifting the throttle as the car freewheels, rather than fuel being cut off (albeit with the subsequent drop in speed) as you lift the throttle and the car stays in gear.

OT but in the early 1990's me and some colleagues when out on a work trip use to have a competition with each other to see who could get the lowest instantaneous MPG figure on a Vauxhall Astra GTE (2L 16V) - I won with 1.2MPG

You need to measure fuel consumption over a few fill ups rather than just range as fuel gauge calibrations can vary. My 1.4tsi Skoda Superb mk II is supposed to have a 60l tank but usually never get much more than 50l in when I fill up. However measuring fuel consumption it's actually surprisingly good - not much worse than the 1.9 diesel Superb I had previously.

 

Be careful overbrimming with petrol - it can do damage to the charcoal cannister. When I first bought my car I brimmed (multiple clicks) my tank in Luxembourg and a while later it displayed an engine management light. As I'd just bought it and it was under warranty I pulled into a German Skoda dealer that was really helpful - they thoroughly checked my car out and despite our clear language barrier got the message from them - "Von click - halte!". I now stop at one click and have never had an issue since. On a long journey driven carefully mine can average over 50mpg (5.65 l/100km) .
