Hi all,

 

I just recently bought a new 2017 Skoda superb sportline 2l diesel.

On paper its supposed to average about 60mpg, but I'm only getting about 33 in cities and 50 on the motorway.

 

Does this imply theres something wrong? I've been trying various things such as turning "engine start stop" off/on, trying to use sport mode or economy mode and I even spent a day just using the paddles to shift gears.

 

Its really soured the whole thing, because my 10 year old honda civic used to consistently get 45mpg

Is there any way to make it change gears faster while in Automatic?

is there likely something wrong with the car? (I dont trust the dealership, as they kinda shafted me, but thats a whole other story)

Is it a 190 or a 150? Mileage on the car?

On the face of it it doesn't look too bad as an average but all depends on driving style, rlative time on motorway/in town, where you are driving hilly or flat, learning the best way to drive the car to keep it in optimum range etc etc.

There are several threads on here about diesel mpg, have a search.

I always reckon on about 70-80% of the claimed (hilariously comedic) figures for mpg on most cars is a good base line to compare.

Well worth a read, though as Sagalout says, much of it is down to driving style and terrain.

Its 150 version, and has just over 10k miles on it.

so it's fairly new.

 

I will give that thread a read, but I'm thinking of selling it now..

I'm putting a lot of money into it every week just to commute and if I cant figure out how to get the economy to around 45mpg I'll just be losing money.

 

thanks guys

Sounds low for a 150 goshtin. How many miles are you doing per week and what do your drivegreen numbers look like? I get 55mpg+ average on the motorway, with drivegreen in the low 70s on my 190 dsg. It drops significantly around town (35-40 mpg) though. Most 150 drivers are reporting c60mpg on the motorway.

 

Surely the depreciation hit at 10k miles will be way more than the cost of the fuel?

I'm being dramatic when I say I'm selling it, but it does still annoy me it's not delivering on the economy.

I'm quite new to all this tech, but I'll look up the "drivegreen" thing.

can you explain briefly what I'm looking for so I can check it when I get back to the car?

 

I'm barely driving at all a week now. I'd say on average about 30 miles a week

Drivegreen is the little green leaf. Press the "car" button to get to it.

I think it represents (out of 100) how "carefully" you are driving. If you press (from memory) the left hand soft button at the bottom of the screen it will also give you what it calls "convenience consumers" which tells you how much fuel the aircon, heated seats etc is using.

I suspect that is the cause of the problem - it will never even warm up. Diesels don't do well on short journeys.

When cold the diesels are not efficient, obviously worse when its winter

 

The lab tests are done with car warmed in a building for hours, not left out in cold

 

If you are only averaging 30 miles per week why did you buy a diesel?

That sort of distance is probably best suited to electric car

i've a 2wd 190 dsg estate. 22k on clock. around town i'm mid 30's, mixed driving will get 43-45, and a long steady motorway trip of c.70/75 will achieve a maxumum of 48-52 depending on conditions. if i go 80, then it drops to mid 40's on the motorway.

Will get better as the summer months warm up.  

Manufacturer's mpg figures are not to be believed. If your car displays when to change gear ignore that also. Mine tells me to change up at 2000 rpm even when going up an incline and in a 30mph area I stay in 3rd instead labouring the engine in 4th just because the display tells me to. I drive in the same manner as I did before the confounded 'nanny state advice' and my mpg is better. When I was in my late teens and twenties I was more brisk by reaching the speed limits rapidly through the gears and then easing off the gas and cruise along virtually on the overrun and my mpg figures were very good even though I used pen and paper to work out my figures.

Cruising along the motorways it takes 50 miles or more to reach optimum mpg figures but it is very rare to meet the 57mpg the manufacturers state claim. Last year I achieved 64mpg along the M1 through the roadworks at a steady 50mph. I drive a humble 1.2tsi petrol Roomster though.

Goshtin is reporting 50mpg on the motorway which sounds a bit low.   I would not rule out the obvious things like tyre pressures.  They don't always prepare the vehicles correctly before pick-up. 

I have had a dealer recall on my Octavia Scout 184 DSG for a lambda sensor, I had noticed the MPG had dropped!

Since the sensor has been renewed the MPG has got around 5/6 mls better?

Could be this?

As suggested above, those sort of weekly mileages are not really suited to modern diesels because they are fitted with DPF (diesel particulate filters) to catch the soot and periodically burn it off (burn off is called a regeneration or regen for short). Quite likely your 10 yo Honda (if a diesel) did not have one as it would likely only have been built to Euro 4 standards.

Thing is if your diesel is trying to perform a regen (which uses extra fuel) and you are doing only short runs and failing to complete then it will retry next short journey...and so on. Total disaster for consumption.

You just need to have a suitable driving strategy and it might be useful to get a cheap OBCD Bluetooth dongle and DPF monitoring app on mobile phone.

 

we had a 1.2Tsi yeti manual.. 53.3mpg in the book, it averaged 35.6mpg over the 13k we put on it from new.. way off the book figures.. never even came close..

I have a Superb II 1.4tsi (facelift, stop/start) - 47.9mpg in the book , real life average 45.8mpg during the 35kmiles I've been using Spritmonitor. Close enough for me.

 

At 30 miles per week the difference between 30 and 60 mpg is about £2.80 per week.  Honestly, it's not worth worrying about.  You can't even buy a pint for that. 

My dad does similar mileage.  I've been trying to convince him to stop buying city cars and get something with a v8   He still can't drop the mpg thing though.

goshtin,   see how many miles you actually get from a tank full and the litres used, 

because Skoda never told you what MPG you might get with you driving your car out on the road in weather.

Maybe use it for 1 week just putting in 'D'  and another week trying other ways of using your DSG.  Do brim to brim to see your actual / factual fuel use.

 

?

What modern Euro 6 car of the same size do you think you can chop your car in for that will give better economy (MPG) for the miles and use you need it for?
