Averaging 30mpg on 1.5 TSI DSG

[Gingerbread]

Hi all,

I'm a pretty relaxed driver, don't really put my foot down at all, hence going for the 1.5 engine - I'm currently averaging 30MPG, this is mostly around town with some longer distance (>30miles) national speed limit trips in the mix... this seems low to me, I was expecting closer to 40mpg to be honest. Anybody else have their numbers for comparison?

Thanks

That seems low but I don't have a car yet to say defo ,car buyer says

The 148bhp 1.5-litre petrol engine


economy is noticeably better, with up to 44.8mpg officially when combined with a six-speed manual gearbox. CO2 emissions are between 143 and 155g/km depending on the exact spec of the car. This engine is available with a seven-speed automatic but it does make economy slightly worse.

Autoexpress says below

The two other 2.0-litre petrol engines both return 37mpg, while the entry-level TSI 150 engine offers very acceptable efficiency. It returns 44.8mpg and 143g/km of CO2


Some other owners may know more

Hi Gingerbread,

Is your car new at all? People do mention that the MPG does start to improve after a few thousand miles. Also with the weather being cold at the moment that also won't help and will also affect MPG. I've definitely noticed this in my current R56 Cooper S with 61K miles. E10 also seems to reduce MPG slightly as well as it has a higher ethanol content meaning it has less energy-density than E5 Unleaded fuel

Surprised you don’t run the S on super unleaded, I thought that this was the recommended fuel for these engines.

OP. Depending on how many miles is on your car fuel consumption will improve, seen them get better at 6 or even 10k, and as the temps rise again in the spring that will help too.

Thats probably not too bad

my average on a 1.5 TSI Leon was 36 mpg

small engines are a false economy

Wife’s 1.4 at 30k miles averages 44ish, maybe a little less at this time of year, she does town use whilst I do the longer (heavy right boot) journeys, long motorway journeys on cruise can see 50+.

I normally do run it on Super Unleaded, but the cost of it at the moment is silly, so just running it on 95 at the moment. Most of my driving is on the motorway and still can get mid to low 40s on a run. Recommended is 95 and it seems to be ok running on it

It is brand new on lease, around 400 miles on the clock. I averaged around 44mpg on my Leon 1.5, which was also brand new. Was expecting a little bit less on the Formentor with the extra weight but 30mpg is quite a bit lower than I expected. Shame

Tell that to my Stinger, you'd be lucky to get 20(ish) MPG on a good day. On a long run it'll do 30 - 32 if you're being angelic with it, sorta defeats the purpose of the car however. Weirdly enough BMW 3.0L engines are great on fuel, I could get 35 - 40 without really trying although they're the exception.

To the Op, I agree with others. Give it a thousand miles at least to bed in and note that E10 will lower MPG a bit as well.

Yeah got to be sensible

in example i bet in the real world there won’t be much between the 2.0l and 1.5l formentor as the 1.5l is having to work harder to lug the weight around than the 2.0l

wltp mpg’s are a nonsense.

on my leon 1.5 tsi i think the combined was 51mpg

i was getting 36 mpg

miles off

Manufacturers get their figures on a rolling road simulation, no wind resistance, no weight, tyres as hard as they’ll go, engine under minimum load, like constantly driving downhill.

I would take it on the motorway, steady 70mph for 30 mins or so. If you’re not getting 40mpg+ after that sort of run, something is not right.

Agree with this. I was sold a 2018 BMW 1 series with a 1.5 litre engine. I was getting about 28mpg driving as perfectly as possible.

I complained and finally got put into a 2 litre diesel... I average around 42.3mpg and a tank lasts about 510 miles.

I feel like a smaller petrol engine in a heavier car is a recipe for poor mpg.

I have a V2 1.5 DSG and I get around 36 to 37 mpg around town and recently did a 200 mile run mostly on motorways but some heavy traffic and averaged 49.

 

[scottydog76]

I have the VZ2 310 and at just over 2,000 miles, I’ve averaged 31.4. It’s improved only slightly the more miles I’ve done.

My commute to work recently, after filling up, averaged 35.3 which I’m impressed with.

Impressive

My long term average on my audi a3 2.0l tdi is only 37.8 mpg ?

I agree, about the same as mine.For comparison I was getting 30ish long term average on the 310ps, average on the S3 was 31/32 but was 38ish driving sensibly on a long run.

Around town with short journeys that's very similar to mine.

It used to be around 35mpg but the E10 fuel, cross climate tyres and cold weather have pulled my mpg down to 30ish.

On motor way runs I get mid to low 40s

I'm very similar to you, sounds about right.

Completed my first long drive yesterday, seemed to do good on MPG .. hoping it will still increase when the engine loosens up
