[Closed] What diesel auto mpg's are you getting?

I've just taken delivery of an 09 BMW 320D and am getting an average of 53mpg. A colleague has an 07 520D and gets 50+ too and he hammers it everywhere.

I got my new E Class E250 CDI auto estate at the end of September, at last the engine is showing signs of improvement in economy. I'm getting 40mpg on motorway runs around 100miles or so and that's pushing it at 85ish. I should say that it does have 19" wheels! Around town high 20s/ low 30s. my 7 mile run to work normally gets me just under 30mpg. It's a big car though and I do tend to have a heavy right foot. For a family mile muncher it's great, loads of space, very comfy etc etc.

I had a Vauxhall Insignia estate 2.0 diesel automatic hire car before christmas & it returned 48-53mpg running from rural Devon to the Midlands 6 times (80% motorway cruising @ 75mph)

1.8 TDCi Ford S-Max. 38-40ish around town. 50 on motorway runs

New XJ, getting a reported 37mpg. Thats mostly A, B and Motorway work not too much time in the city.

The wifes' Freelander get 33-35 mpg.
A riding buddy's 530d was 32-35 mpg.

I think that urban running hits them quite hard.

The new 520d is supposed to be very good, but with any car I always look at whatever the worst number is on the official figures - and assume thats what I'll average.

Passt 2006 2.0 TDi auto gives from 35-45mpg around town and 45-55mpg on long motorway trips. At the top end of those ranges in summer, and the bottom end in winter of course, like all diesels.

Honda civic for me.2.2cdi o-60 around the 8 second mark and at the moment the average mpg on the computer is 49.4 also it was great in the snow because of the front wheel drive

Total Fuel (l) 957.50
Total Miles 13858
Ave. MPG 65.97
Ave Cost per mile £0.08

Blimey Dibbs.... What diesel automatic are you getting 65mpg out of?

i was just about to ask the exact same thing lol

Smax 2.0 diesel auto. 40mpg hooning it to the Alps. 40mpg chuffing about locally.

[Embarrassed] Smart CDi Cabriolet (799cc's of turbo-charged muscle 😆 ) [/Embarrassed]
I've had 70+mpg out of it but I'm still disappointed as they claim 84mpg, zero tax band though.

Last year I had a 55 Plate Passat Diesel 130 that would regularly get me between 55 and 60 mpg from a mix of motorway and urban

VW Golf Estate 2.0 - about 46 to 55 depending on weather and driving style.

But I'm not an eco-driver 🙄

toyota hilux 4x4 33 mpg

XF, 35-40 on short journeys, 45-50 on the motorway, can get it down to low 30's if I'm having fun. Best I've had on a run is 57.6.

Best I ever had out of my '56 2.0 TDI 140bhp [b]manual[/b] was 39mpg and that was a mix of motorway and urban.

I wasn't exactly gentle with it, but it amazes me that people manage to get over 50mpg out of a variety of cars - auto's at that.

65mpg from a smart isn't so good when you can get that from a much bigger Golf or Prius, or even a Passat bluemotion.

In my Passat, I set the cruise on 70 and leave it there - best I ever got from Cardiff to J12 was 57, all summer it was over 50mpg to that point. However at 80mph it went down to 46 or 48.

There is a knack to economical driving, and I don't mean going slowly although it clearly helps.

STR - I got 34mpg on a run with a caravan on the back, and only regularly get down below 40 on pure urban driving in the winter. You clearly don't have the knack 🙂

40mpg out of a mercedes vito 120cdi, 208bhp, unless i hoon it, in which case 25-30mpg
- not bad for a six seater van

65mpg from a smart isn't so good when you can get that from a much bigger Golf or Prius,

Just a thought, how is everyone working our their mpg figures ?

Are you all doing it the 'correct' way, i.e mileage done over a tank to tank fill up, or the 'incorrect' way, i.e. going off what it says on the trip computer ?

Depends where you have to drive, a workmate has a Prius and he's struggling to get 50mpg on the same route

It's all in the technique. You do have to pay attention to what you're doing, and that hybrid system is more sensitive to technique.

I'm going by the trip computer, but I have checked it against tank to tank and it's one or two different either way at random.

The secret is to use cruise control whenever you can.I know it can be a pain in the arse but you try it, it works.

Discovery 2.5TDI 4by4

22MPG

WIth current price hikes 120quid to fill it up

STR - I got 34mpg on a run with a caravan on the back, and only regularly get down below 40 on pure urban driving in the winter. You clearly don't have the knack

No - I clearly had a company car and fuel card.

Still never used to get close using cruise control though.

Get between 28mpg & 32mpg in my 2.5l 170bhp TDCi Ford Ranger atm.

520D, 1/2 urban, 1/2 motorway, averaging 43mpg over the 6 months I have had it. Would be better but for a reasonable number of cross country runs at quick pace for emergency call outs.

Got 40mpg out of previous Vectra but suspect my driving style is more relaxed in the new wheels as it is so much more comfortable and pleasant to drive.

Nissan Skyline R32 2.6 single turbo petrol. 643bhp

yet to get 6mpg...

But I'm having a hell of a lot more fun than you bunch of boring buggers

Aye Zed you will have more fun.

I however will get to my destination without bankrupting myself.

Having said that still wish we had kept the wife's MX5 for fun. Tried hard but can only get the rear to drift when its snowy in the 520d touring. Not quite the same.

wifes panda diesel - 55mpg
my bmw 530d - 38mpg
my 07 transit 2.2 tdci - 28 mpg

I spend so little time driving my cars/motorcycles (due to my job) that the cost of fuel does not matter.

That's not a good thing though....

I looked briefly at a 535D but decided that given the mileage I ususally cover it would have been fun but foolish. Sad when life intervenes to stop you having fun, either from too much time or too little time behind the wheel.

65mpg from a smart isn't so good when you can get that from a much bigger Golf or Prius, or even a Passat bluemotion.

Cant be arsed to work out all that £££ spent vs miles driven ([b]get a life[/b])

Screen shows about 38-44 if I boot it around, 46-48 if using cruise etc and longer journeys.

2010 170CR DSG VRS hatchback

Is that actually true? Ours is manual but Katie always seems to return higher mpg than me despite me using the cruise and she very rarely. This is on a typical UK journey with a bit of city and a lot of motorway (so the majority of the trip would be on cruise for me). We both drive at the same upper speed limit.

Touran 2.0 tdi DSG. 45 around town 55 on motorway.

I use cruise a lot, helps lessen tyre and brake pad wear and keeps things more constant, on the motorway you often see cars accelerate past you only to slam the brakes on a few seconds later.

Sometimes I use satnav when I know where I'm going and have lots of time to spare, it'll sometimes tell you are going to be very early to a meeting and I just dial in 60mph or similar on the motorway, take phone calls etc, relax, let everyone overtake you, still get to where you're going on time and save money on fuel.

God, I'm really boring myself now ZZZZzzzzzz

I use cruise a lot, helps lessen tyre and brake pad wear and keeps things more constant, on the motorway you often see cars accelerate past you only to slam the brakes on a few seconds late

exactly - it's very rare that I'll actually use the brakes on the motorway. Read the road ahead, slip the cruise off if you need to lose speed, then kick it back in again. It never feels like the computer fully opens the throttle to regain speed either. Katie tends rarely uses it, and whilst she doesn't exactly do the tailgate/brake/tailgate thing she does tend to be on and off the brakes and accelerator. Yet the trip computer seems to show better economy when she drives!

25 at a push

I'm getting 40mpg on motorway runs around 100miles or so and that's pushing it at 85ish.

Pretty much the same a my e320 cdi auto 😀

 

48-50 out of my 1.8 Mondeo TDCi, 35ish from my Freelander TD4.

2004 525d auto tourer. E39 so last of the none emissions/cost friendly ones with £250 tax.

Averaging about 36mpg. Will do 40-42 on a run at anything between 75 and 100mph. 32mpg knocking about locally with a light foot.

Cold and short runs hammer any big auto.

Jeeesusss! The only way to calculate MPG is to calculate how much fuel you put in the car and then use your sat nav to calculate the actual milage that you have done. Then repeat this over the year summer to winter and calculate the average. Glancing at the on-board computer when your freewheeling downhill is fooling nobody. My wife who does a genuine mix of urban and motorway miles in her albeit still fairly new swift 1.3 diesel can just about average 50-52 mpg. When I work it out properly its about 46mpg. Speedo's always read high and ergo the on-board MPG figures do as well.

Wow you guys are like, so cool.. Do you go to a lot of parties?

1994 E300D Merc estate. 34mpg. ostensibly diesel but will run on (almost) anything

Saab 9-3 TiD Estate (ok, it's manual) on a 57 plate. I get about 42mpg on average over a tankful, commuting Shipley to Barnsley & back.

I reckon it'd be better if I lived nearer the motorway network, without having to cross Leeds/Bradford to get there. Having said that, I don't use the M62 on the homeward leg, I tend to go more urban or the long way round; if I did use the M62, I'd still be there now 😉

Long way round adds about 10 miles but doesn't take any longer...

Rock and roll..!

djglover - we all know you are the nobber who brings a 4 pack to the party and then stands in the kitchen all night being unsociable, yet somehow managing to get pissed on everyone else's beer. In fact, who invited you in the first place?

I got a lift off you as I couldn;t afford the petrol

Speedo's always read high and ergo the on-board MPG figures do as well.

Cleverclogs, did you know that the odometer and speedo are independent systems on a modern car? The speedo can be calibrated differently to the odo and whatever system the trip computer uses.

My car tells me it's doing 29.7mpg over the last 3000 miles. Having checked miles travelled versus actual fuel used (complete brim-to-brim) shows that the computer is accurate (if anything it's slightly pessimistic).

Land Rover Discovery 3. Strangely, it's about 5mpg better than my previous Disco 3 despite having 125k miles on it.
