i have a 2.0 litre diesel and its only done 500 miles.
41 mpg seems a little low for a diesel. taking away the fact its not got many miles on the clock and this MPG is mixed driving i.e some motorway 70 mph and some town/rural say average 50 mph. anybody got similar mpg or comments.
nope i'm not heavy footed i'm police standard training.

[iangte]

it is quite low mate my vw bora 1.9 tdi 250bhp. (chipped) does 56 mpg overall an i use it to tow cars round the uk

[rosco]

im only getting 20-25 out my 1.6 turbo :D

nope i'm not heavy footed i'm police standard training.

The Insignia is a very heavy car, 41mpg is quite reasonable, a few some users have reported figures of around 37/38mpg so I would say 41 average is about right. This is comparable with the Ford 2-ltr Mondeo diesel, my sons Platinum X estate returns about the same figure.

IOW... sound about right.

[para999]

You say about being "police trained", with all respect, from what i know & learned from "advanced driving" i was always being told about "not being in a low enough gear" through towns, they're expecting me to drive in built up area's in 3rd gear??
If you're doing similar as defence driving then the consumption won't be as good?(-:)

basically roadcraft states you should be in the correct gear at the correct time for the conditions to be able to respond postively to any hazards etc.
mmh built up areas some you have to drive in say third gear when its crowded but on normal open built up areas as these motors have 6 gears ( as you know ) fourth gear is ok.
going back to fuel economy the book states a rough average of 54mph but maybe as you say its cos its new:D

[para999]

wont let me edit my last post so just a p.s sometimes 5th is ok its just dependant on road conditions.
not trying to teach you to drive here just explaining the ethos of 'roadcraft'.:)
maybe once i have the vxr styling pack fitted it will improve he he

[happymonk]

I am sure that this will get better as the engine loosens up. Happy42, i believe had similar issues, yet its doing better.:):)

the reason for the correct gearing is, imagine your on a mountain bike and going up hill, if you have it in a high gear it takes more effort (energy) to turn the peddle, where if you have in too lower gear you will get no where fast just rotate the pedals more using up unnecessary energy, getting the right gear you will still achieve the ultimate goal of reaching the top but having used lees effort.

now convert that to a car, the engine are your legs on the bike they are straining more to make the gears move in too lower gear and working too much in a higher gear, energy = petrol

[martin99]

I have to state that the mpg on my insignia is the worst I have had from the diesals I have driven recently.
My Insignia gets 46 mpg as an average
Passat 52mpg
Mondeo 50mpg

I am driving the Insignia even more careful than the others just trying to get the mpg up but can't. Current mileage now at 15k

Your figures Martin are not so bad as some others I've heard, certainly no where as frugal as the old vec-c 150's were though, and IMO a touch less pokey, but thats likely due to the weight difference.

[iangte]

it is quite low mate my vw bora 1.9 tdi 250bhp. (chipped) does 56 mpg overall an i use it to tow cars round the uk

really think theres something wrong there guys, as i stated at the start the bora i run is rolling roaded at 250bhp and runs a better mpg, have you tried getting your ecu's re-mapped

[happymonk]

JC done a test not long ago so many cars filled to the first click then driven combined town and motorway then back to the same filling station and re-filled non of the cars got the manufactures mpg but all was with in 10%

so if you have the ecoFLEX said to do 54mpg the average driver would get 48.6

[Amos]

I?m getting 42 mpg overall on a tank full, On my vectra I was getting more put the sport tourer feels lot heaver when I chipped my vectra from 150 to approx 190bhp I was getting about 4mpg more, it had more power low down so you dint need to keep changing down the gears to keep the revs above 1900 rpm in town.

[rosco]

i averaged 27 mpg over 360 miles at speeds of between 100 and 140 mph autobahn before anyone starts saying how illegal it is.

[mitch1408]

hahahaha, nice! How did it feel at those speeds? Twitchy or nice and stable? ill be testing mine on the A1(M) autobahn when it arrives! lol 27mpg isnt bad at that sort of speed though :)

Infact its pretty good lol

it may not be an ecu remap but it does the same sort of thing and ive had one for 3 years and boy did it work well!!! :D standard the car was 150bhp and with this on 190bhp. standard mpg was 44mpg and with this on 56mpg. and yes insurance companies do accept them as fuel saving devices!!!

I have an Elite ecoFlex and after a week am averaging around 43mpg, I was hoping for a little better considering I paid the extra for the ecoFlex but possibly too early to tell.

well after a week of ownership and all different driving styles my 160ps sri cdti is showing 38mpg with 700 miles on the clock. from brimfull to flashing reserve i got nearly 600 miles from a tank :rolleyes:

[StormBoy]

I'm generally getting 37-38 mpg, a mix of both motorway and town driving. Not managed to better it by much in 20,000 miles and it’s also had its first service. How long should it take to loosen up???

mk2 all the way, so much more fun. and its got the whole thing of, newbody off mk2cav and i have started rebuilding it so will be worth more to me too. pluss getting a mk2cav sideways is SO much funnier then getting an insignia sideways (press and hold traction control button:D)

was having a look at the pics on mk2cav. going to be looking fantasic when its back on the road. (-
i know what you mean about driving them though. just makes me smile when i'm out in it. take it nearly everywhere now. Poor Shogun's dumped on the driveway. was thinking of putting it off the road for a couple of months btu really don't want to. you never know when the suns going to shine:D

OK, so I'm on about 1250 miles now and have reset the avg mpg counter on my last few trips. So far my elite 160 ecoflex is averaging about 31 in town and 42 on motorway. I have another 500 mile trip coming tomorrow so I'll be looking at it again some more :)

Those fuel consumption figures dont seem good at all, especially for diesel, I'm getting 39.6mpg out of a petrol 2ltr automatic.

VX seem to be crippling consumption figures by all the complicated emmisions control gadgets diesels seem to be adorned with these days. I'm sure my old 56 plate cdti 150 vectra diesel had far better fuel figures. I would have expected that 160 to be up in the high 40's and even into lower 50's on a run.

my 56 plate astra 1.9cdti 150 only managed 45mpg before i "tweaked" it with a green box and then i got 56mpg for the remaining 2 years. ive just come back from an 800 mile round trip up to scotland and my 160 insignia is slowly creeping up - it was on 39mpg before and its now on 41mpg......:)

Thought you could switch off Climate Control as well as you can turn off Air Con.

You can.. just use it in manual mode, which is what I used to do, as long as the aircon led is off its obviously not being used, you can still have heat control and get basic natural ambient cooling without using the aircon .

Those are the sort of figures I would expect to see, and are similar to what I used to get from my 160 diesel though I had used to go up to 75 ish on motorways. The Insignia is a very heavy car, and I'm sure this has some detriment affect on fuel consumption too. TBH I think if the figures are anywhere in the mid forties I think thats quite reasonable, its when it falls down into the mid thirties as some owners have reported that it starts to look a little poor. I agree with you about using the cruise control, mine always seemed to show better figures on long runs if I used it frequently.

[mitch1408]

Well ive had mine a whole day now and done 300 miles!! Im on for 600 miles for the tank which isnt too bad for the first one. Sat on the motorway at 75 with the crusie controll on it was returning around 45mpg. Hopefully this will increase!

Really happy with it overall! :D

have now done 3500 miles in my exclusiv ecoflex, am averaging 52.7 since day one but really cant get it any higher. seems to do better mpg at 75mph on motorways than at 70 or lower. normally get about 700 miles till the light comes on!
i have noticed however, that around town it is real real xxxx, and it pulls the average down real quick. my old 150 cdti vectra was much better in town.
might look into a bit of k&n magic, it did wonders on the vectra.

I would be quite pleased with those figures matey, I thought the Insignia really came into its own once it was on the motorways, drive-wise anyway... even the underpowered 1.8 was quite decent once it got going. However the most I could every manage on a run on my last 1.8 was about 34mpg, but it only dropped to 33 when driven round town so not a lot of difference.

You will get a big drop around towns etc. compared to the vec-c the Insignia is a very heavy car and more akin to a lumbering elephant around town, it's like permantly carrying 2 passengers all the time compared to the nimble veccie.

[Phelix]

My Vectra 1.9 150 Auto Elite did 48+ mpg recorded on computer and verified with regular calculation checks.
My Insignia 160 Auto Elite does about 37+mpg on computer when checked against calculation actual is 40mpg.
I find it confusing when co2 emissions are lower on Insignia?

From what I can see that seems about average for the 160, though it will return better figures if you drive with a very light foot.

I assume you mean confusing that it has a lower emmisions rating but is slightly heavier on fuel?

It's actually the emmission control measures on diesel engines that prevents most modern diesel engines from performing as well as they could be. Take away all the emission control gadgets away, and you would be pleasantly surprised how the performance and fuel economy would increase, reliability would also increase too as its usually the emission controls that cause most of the problems with modern diesels.

Manufacturers are continually endevouring to lower emmissions on new cars for obvious reasons, and you pay lower road tax too, its a case of striking a balance. Modern day diesel engines have become quite a complicated beast due to all the electronic emission controls they have these days. Lets face it, all engines rely heavily on lots of electronics to function properly these days, none more so than modern diesel engines.
Anything that prevents a engine from gassing and breathing properly will have some effect on its fuel economy and power too to some degree. A small price we have to pay for cleaner engines.

[svpworld]

Only filled up once since I've had the car but managed to get over 830 miles from a full tank before the light came on. I'm sure I could stretch it to nearly 900! That's mostly motorway driving at 60mph with cruise where possible and gentle driving elsewhere, anticipating the road ahead etc. It beats the Vectra C 2.2DTi I had and the Corsa 1.2 petrol.

[thermalactivity]

have you got a the eco engine then as that seems quite a lot of miles from one tank full as im only getting 600 from my 160????? :confused: :confused:

[svpworld]

Nope just the standard cdti 160. I do drive gently though and always keep revs as low as poss. I drive 100 miles a day back and forth work and about 70% m'way. 600 miles is rather low, I used to get over 650 from my vectra 2.2 dti and over 450 from the corsa 1.2 petrol. Used about a quarter of a tank in the insiggy on a round trip between cardiff and london heathrow airport, pretty impressive!

[thermalactivity]

i drive anywhere between 100-300 miles per day and the same as yourself 70% motorway with cruise control on at 70mph. in the month or 2000 miles ive had the car im only getting 600 miles out of a tank. in fact this last tank looks like it will only stretch to 500 miles! :confused:

[svpworld]

Well first off my car has already done 10,500 miles when I bought it, so it's been run in. Also I don't cruise at 70 that often, more around 60 mph and I've learnt to ease off rather than braking last minute... Most importantly I tend to drive with the revs around 1500 most of the time and change at 2000 or less. I don't know if the SRI is any different or if it just needs running in, but I've always managed to get good economy from the cars I drive including my Vectra C SRi 2.2DTi which averaged around 650 from a tank. Maybe yours needs to be run in a bit more?

S.

[Vectra-Arctic]

I'm sure you all know, but how a car is 'run in' is all important to things like fuel economy, braking system performance, engine reliablity etc.

Small underpowered engines in large heavy cars (1.6 Turbo for example) is never going to be fuel efficient and it's revving hard just to move the heavy car. Even the 1.8 VVT is in my opinion underpowered for the Insignia/Vectra C/Signum sized cars. 2 ltr Petrol or 1.9 ltr Diesel is and should be minimum specification.

My 1.8 Vectra B's are more fuel efficient and better mpg than my 1.6 Astra or my daughters 1.4 Astra.

Drive more fuel/car friendly and see what you can do.

Just coming up to refill again, fuel light came on at 820 miles since fill up this time using ordinary Shell diesel. Really impressed at the economy, though too early to notice if Shell is any better than supermarket fuel.

The demo CDTI car I took out for 24 hours had the same economy on paper and in real life as my Seat Leon does now. I got (and get in the Seat) a full tank average of around 43 MPG, this lifts to around 45-47 on a really good run.

The crusie control on the Seat is far more thirsty than learning to drive diesel-style with your foot.

Best way to get economy up seemed to be to "drive it like a cabbie", get through the gears really quick, shift up as soon as it will pull the gear and never put your foot down! Keep rolling off all the time on any long striaght roads and you seem to be able to maintain your speed and keep lifting your foot and you can get the display to show some much bigger numbers.

As Seat has had a new engine I have been able to check this twice but the engine has a sweetspot in its run in period between about 7k and 20k when economy is brilliant

You diesel guys don't know how lucky you are. I'm still only getting about 24mpg or less in my 2 litre petrol Turbo 4X4 Sports Tourer SE, and that's driving carefully. Even on motorway journeys I've never got more than 30 mpg. Good thing I don't have to travel a lot.

[afisher]

That's why I ruled out the Petrol and went for the Diesel. I thought that on the rare occasions I ever need to go fast then the 160 has enough power.

[svpworld]

For the miles I do, I couldnt run a petrol. In any case the torque of the cdti 160 is outstanding for overtaking and hill climbs. The only disadvantage I see is the noise when cold or driving slow, but once warmed up it settles down nicely. I remember my last diesel, never had to buy an exhaust, no ignition problems, even ran it dry a couple of times but got it started (though wouldnt risk the same with a cdti as opposed to the dti). I suppose diesel is less solvent like than petrol so better for the engine and bits. Of course now that diesel is almost the same price at petrol it makes even more sense if you do the miles. Shame that Vauxhall haven't come up with a refined quieter diesel engine as have Ford and Jaguar. I miss the silent running and refinement at low speeds of a petrol, of course I am comparing to a 1.2 corsa D which was a sweet engine... but really underpowered and less economical than the big insignia diesel!

Just coming up to refill again, fuel light came on at 820 miles since fill up

so it seems like your getting 55mpg on average and EVERYONE else with the same engine on this forum is getting between 38 and 45mpg!!
are you sure that your information system in the middle of your speedo and rev counter is set to IMPERIAL and not METRIC by mistake??? as this would then make you think that youve done 800 or so miles when it would actually be kilometres? :confused:

[Rockh]

42 for me at the mo. Furthest I've got on a tank is just under 700 miles and that was all motorway at stupid o'clock in the morning so not much traffic and cruise was on most of the time.

[svpworld]

I am absolutely certain my consumption is correct, as I travel 450 miles back and forth to work a week from Cardiff to Yate, and after filling the tank to the brim I often only need to fill up after the light comes on when I get to work on the 2nd Friday. Its about 90 miles a day and I've been using Gas Cubby on my iPhone to record the last 3 fill ups. According to the data on the phone here are the figures since 18 October....

filled up 18 Oct with 41.95 litres
filled up 30 Oct with 65.16 litres
filled up 10 Nov with 66.20 litres

Average so far 57.2 mpg based on 1653 miles and 131.36 litres and works out at £0.09 per mile. As I said I think I've perfected eco driving and let the car's momentum do the moving whenever possible, just prodding the gas to keep it moving. Most of the motorway driving is 60 mph, occasionally up to 70.
Once I get a reasonable amount of data on gas cubby I'll upload some more average stats for you all to see. Car has done around 12500 miles so far and I am usually keeping the rpm between 1200 and 1500 on the urban run and about 1800 on the motorway. Rarely exceed 2500 rpm-3000 rpm unless I feel the urge to make some progress or overtake.
I'm sure I could achieve even better mpg by avoiding the weekend urban mileage and sticking to the motorways, but not sure there is any point in doing so... just nice to see how economical I can get the insignia! The trip computer matches up well to the mileage I am doing and the fuel put in.

In my 1996 1.6 8v Astra, (waiting for delivery of Insignia) I found that when I started to monitor my fuel economy it changed my driving style. I started to drive more effeciently to see what milage I could get. I managed to get 40mpg, which I didn't think was too bad for a 13 year old car :)

Once I started to forget about recording the fuel and milage, my driving style reverted back to lead right boot and the mpg went back down ;)

I will take a close look at the consumption in the Insignia 1.6turbo. If I get it remapped I will do the same and let you know what the results are.

In Elite Nav diesel getting 42mpg , not good i was getting 52 in my Avensis, but this is a very heavy car.

I guess it depends if this is a personal or company car in the satisfied stakes, those who hav fuel provided will not be too dismayed, this car is mostly aimed at a fleet market.

[mortmain]

1200 kms out of my 160 ecoflex, averaging 5.2l/100kms - Ireland has gone metric and i can't be xxxxd changing the info display. I'm well happy with the economy but I live in the sticks and do no town driving. I reckon the low rolling resistance tyres make a big difference and may be worth considering for those who are unhappy with the economy on the CDTI's.

[svpworld]

What are the tyres on the Ecoflex (size and make/type)? I know the current ones I have on my Exclusiv with 17" steel wheels are very expensive!

Simon

[mortmain]

As far as i recall (the car is in getting a new flywheel) they are Michelin Primacy 245/45/R18's, probably not cheap.

[mitch1408]

the tyre pressures on the ecoflex models are higher too.

[para999]

As far as i recall (the car is in getting a new flywheel) they are Michelin Primacy 245/45/R18's, probably not cheap.

is that what you call low rolling resistence tryes then?

[mortmain]

Collected the car again this morning and it has indeed 245/45/R18's they are michelin primacys and are low rolling resistance tyres. They do require higher pressure and i have to admit that they cause a bit more road noise than the standard, by according to the boffins, they really do help with the fuel economy, the bad news is that according to camskill, they will st you back £780 for a set of four - you'd need to be doing a lot of driving for the payback.

[carpetmonster]

Thats £195 a corner, but bearing in mind the front will wear quicker, it would only be two per 12k miles?
Thats not a bad price for these really, i know i wouldn'tt use mich's,i hae them & would find an alternative..:):)

ive got the 17 inch standard wheels on the ecoflex, and yes ive been quoted about £185 per corner, however 1 week after service im on 28000 miles, and still got just about 5mm tread, so hopefully 45k per set, which really upsets my tyre dealer! car also now clocking 58.7mpg average, about 850-860 miles to the red light.

[simonrh]

Car has hit it's stride at about 11k miles and economy is improving nicely now. Getting 43-44 mpg fairly reliably now.
Good car and, touch wood, no problems.

[AidenL]

10 weeks on, 9000 miles up - average 44.6 mpg :)
