Do Not Sell My Personal Information


A bit surprised, should have done my homework!


Recommended Posts

I have just bought a 2016 Ford Focus 1 ltr eco boost with auto gearbox, it has only covered 7,000 miles since new, I love the way the little car drives but I have to say that I am more than disappointed with the mpg, lucky to break 29.5 around town & I haven't really tried it out on a run yet but would not be expecting to get much more than around 33 mpg. My KIA sportage 1.7 returns better mpg & it is a bigger heavier vehicle, it's diesel right enough...🤔

Why on earth would Ford go to the bother of producing a 1 ltr 3 cylinder engine that returns such miserable mpg & then to rub salt into the wound they have the nerve to call call it an ecoboost...😂

I have to say though the wee engine is pretty nippy & the auto gearbox seems to perform well.

I have a 2019 Focus with 1.0Ltr Ecoboost Manual Box 5K miles I get around 32mpg local but an easy 50mpg on a decent run.

I did a 120 mile work trip in my 2010 1.6 slush box auto last week and got 43.5 MPG up and down the A168 and A19 

 

That is as per the data on the info display, I haven't actually checked it with a top up yet. 

Theres a clue in my forum name.....................

Best way I've seen it described with these engines is you can have eco or boost but not both.

With mine, I average around 35mpg on my journey to work which is around 10 miles each way.

My partner in hers on a longer commute gets around 40mpg.

On a couple of long motorway journeys from Essex to Liverpool and Wigan I was showing around 60mpg according to the onboard computer.

I’m at 33.4mpg. Tends to go up .1 every time I go a long journey. The 1.5L 3 cylinder was definitely made for the motorway. 
Yours is a 16 plate?  I thought 3 cylinder engines were new with the Mk4...

You can't compare diesel with petrol for consumption.  They work in totally different ways, petrol consumption will always be worse when comparing power or engine size.

My 1.0 EcoBoost does 45mpg in suburbia.  My 2.0 TDI Golf does 55mpg over the same roads.

I know I'll have to spend more on fuel for any petrol, but short runs just aren't suitable for a modern diesel so don't have much choice there.

If you're constantly spooling up the turbo you will get awful MPG. Most of the time it's not the car, it's how you drive it that has the biggest effect on MPG.

I drive like Morgan Freeman with Miss Daisy in the rear seat 29.5mpg I drive like Vin Diesel & get 29.5 mpg, maybe I should drive in my slippers & see if that will make a difference...😀

125 2020 Active here, do 35mile each way commute, currently at 47.3mpg computer calculated and around 43-48mpg based on mileage/amount filled at the pump, depending on temp, traffic etc. A good long run in 6th gear helps massively.

You should easily get into the mid-40s mpg on a decent run & circa 10 mpg less on short runs, unless of course you have a heavy fight foot.

I will taking a longer run this weekend with some decent straight A road driving, so I will see how I average out then, thanks for the input...😀

No problem, that's what here is for 👍🏽

Out of interest I just checked my trip computers. My current run is 46.3 mpg over 168 miles, which have been mostly motorway & A roads.

The lifetime of the car is showing 42.8 mpg from just under 3k miles (picked the car up on the 1st day of lockdown last year!). Due to the last 12 months very little driving has been in busy stop, start traffic & I no longer commute so that will all boost the figures. Offset a bit by it being a young engine that is probably only now starting to really bed in.

I just cannot believe these figures ... something, somewhere must be wrong, surely.  Admittedly I have a manual 2018+ Focus, but I am getting (on the dash) 47-53mpg ... and I am no angel when it comes to speed (as my bank balance is about to find out ... again!).  I must do a proper check on actual mpg.

your problem is coming from a tractor.... they operate and run very differently.  You are no doubt used to using MASSIVE throttle application.  To get anywhere near a tractor's fuel consumption you must stop that.

the turbo allows it make the grunt of a much bigger engine... but in doing so a petrol engine will drink like a fish

pretend there's a feather between your right foot and the throttle pedal.... and the idea is to use so little throttle all you are doing is stopping it falling to the floor... (if you do that it'll do 50mpg).  yes it'll be doing 0 to 60 in 16 seconds, but magically you'll be going just as fast aa the other idiots out there stuck in the speed camera and traffic jam infested roads... and then try to use the cruise control ALL the time.... 

use cruise and the throttle will be open JUST enough to maintain the speed

fast driving is about anticipation and carrying the speed with good observation, great lines and car control....  manage the gap so you flow through junctions and always hit lights on green and you'll save the planet and get there an hour earlier than a hoddie with his filter kit and a remap...

people are like babies, they get a kick out of the acceleration but it drinks fuel...

Admittedly manual but my MK3 1.0 ecoboost driving to work and reading the road ahead I regularly got 60+ mpg. Repeated week after week. All depends on the driving style. Same goes for my Mondeo I now have. 2.0 tdci and still get the same 60+ mpg.

Just a wee update folks, I have just returned from a weekend at the caravan & the car was returning 47.8 mpg, this was a mix of motorway, A & B road driving also a little around town stuff, it would appear that there was a fault between the seat & the steering wheel...😉 I had not reset the trip computer or the average mpg since I had a new oxygen sensor fitted & the dealer said that I would be getting a spurious reading because of this, he told me to reset & it seems to be fine now, if I can keep returning 47 on a run then I will be quite happy...😀

Thanks for all of your input troops.

tyre pressure at least 32PSI ? and how fast was the motorway element of the run (and of course you weren't taking the van on the back where you) ?

85 mph will drink lots more than 65 mph,

and 56 will be incredible mpg.... and shockingly you'll only be 2 mins behind the guys with no brake pads and front bumper damage, (who's been trying to clear a path so he can do 90 and get special little presents in the post)

don't get me wrong, we should all be doing 50 in a 30, 85 in a 60 and 130 on the motorway but we are no longer free - George Orwell didn't even think it would be this bad

I take it it's the torque converter auto (6F15) not the powershift? 2016 was the change over point.

We have a 2017 1.0 auto (6F15) and the fuel economy is woeful around town, worse on stop/start journeys. We have found that running on minimum 97 RON unleaded helps (it gives a bit more throttle response) and around town we run the transmission in "S" instead of "D" which then keeps the transmission in 3rd gear at 30MPH whereas in "D" it will go into 5th, which is just plan stupid (1,000 RPM) because if you need to speed up the gearbox has to drop 2 gears.

The 6F15 box has very tall gearing (3.44 final ratio compared to 4:22 on the manual) and has torque converter slip in first and second gear, which doesn't help in stop/start traffic. Once you get it on a run though, the fuel economy is very good due to the tall gearing.

Try and keep your software updated if you can

high revs need much more fuel to spin the engine and pump massive quantities of air for nothing....

get out of sport and let the auto box do its job of using JUST enough revs on a very light throttle to get the job done

get that cruise in play - it helps.  Yes on a mild set of hill it wastes a bit, but as the crooks in the council hid a camera on the way down it helps, and the waste by not carrying speed up the first third is overcome 10 fold by not accelerating and braking like a halfwit all the time

Erm, no. As I said, At 30 MPH in "D" it's labouring in 5th at 1,000 RPM, not good in a turbo charged engine and the instantaneous fuel economy will show about 24MPG or less (If you can hold it long enough). In "S" it will remain in 3rd gear at 30 MPH, cruising at around 2,300 RPM and the instantaneous fuel economy will show about 65MPG. Car only does short stop/start journeys and used to average 23MPG until we switched to "S" and it now averages 29MPG, still poor but not as bad as before

"JUST enough revs on a very light throttle to get the job done" doesn't work when you're on turbo lag

Have never driven an Auto but what you have put works in a similar fashion to manual as almost everyone else knows there's no point being in 4th at 30mph @ 1000rpm just because to "green arrow" tells you to. Keep it in 3rd until you know you can progress better into 4th and so on.

Can't comment directly on a Focus auto but even in my manual Fiesta I find, that for my mix of driving, I get better mpg letting the engine run easily around 2-3000 rpm on a light throttle, very rarely using 6th.

The ecoboost is a very interesting engine, but it does seem to be difficult to get the best from it, particularly when coming from something else. A mate of mine (a long-time diesel driver) was seriously considering a Focus but after several test drives he said he "just couldn't get his head round" the ecoboost and ended up buying another diesel.

There are lots of threads about 1.0 ecoboost mpg. Looking at it in a slightly different way, it's not that long ago**that a Golf GTI or similar was producing around 115 hp and maybe doing 35mpg overall. If someone had said to me I could have an engine with a turbo, 4 valves per cylinder, variable valve timing etc, etc, producing 125 to 140 hp, and capable of  returning 45 mpg+, I'd have been very doubtful. If they'd told me it was a 1.0 3 cylinder I would have said they were completely nuts!😀

(**Er, well, maybe it is but I'm getting old!😀)

The main issue is with the 6F15 transmission. It's a typical of Ford, that'll ******* do transmission.

They had to replace the failed DPS6 powershift in the 1.0 petrol and the bean counters wouldn't let them use the 6F35 (as used on the 1.5 MK3.5 Petrols) due to cost.

The 6F15 was never intended to be used on a turbocharged 3 cylinder engine, it was designed for the Chinese Escort (1.5 4 cylinder N/A).

Same reason why the Ford Capri 2.8 injection 5 speed gearbox was inherently weak. There were 3 derivatives on Type 9 5-Speed RWD gearboxes: 4 cylinder Petrol, Diesel and V6 Petrol. The Sierra and Granada V6 manuals had a 3:64 final drive ratio, The Capri 2.8 injection 4-speed had the carry-over 3.0 Capri final drive ratio of 3:09. Ford would not spend money re-tooling the rear axle on the Capri as it was planned to end production at end of 1984MY (when LHD died) and the V6 gearbox made it even more over geared, so the only gearbox that would work, without spending any money, was the 4 cylinder box.

It didn't work, as we know, but you only got a 12 month warranty in those days, so tough.

6F15 is way too over geared - 3:44 Final ratio for the 6F15 - 4:22 Ratio for the 6F35 and manual gearboxes.

So my initial advice to the post was not in general about automatic transmission driving or use, it was/is specific to 6F15. In the Mk8 Fiesta BTW it is fantastic due to the lighter weight of the vehicle and the torque delivery of the 100PS engine, but in a MK3.5 Focus and EcoSport, it's appalling.
