When I put diesel in the car I put enough to get the needle one notch before full it’s now on 2 1/2 notches above empty and I’ve done 230 miles mostly round town about 60 miles of that on motorway

Hi Gareth - if you only live 1.5 miles from work your commuting MPG will always be crap (as you will always be driving round on a cold engine). You also indicate that most of your miles are town driving so your car might in fact be returning some very respectable MPG

Your probably right. I’ve just come from owning a Audi A4 1.9tdi which was incredible on diesel round town and on a run was just hoping for maybe a bit more then I expected with the volvo

To put into context my old T5s used to get 29-33 mpg depending on usage.
My current 3.0 4 wheel drive auto diesel does around 40mpg and up to 45 on a run.

Having said all that, if you are just driving 1.5 miles (around 5 minutes?) Then you will be doing pretty well to get 30mpg and will probably soon be clogging up your dpf.

A remap shouldn't affect the thermal efficiency of your car so all things being equal it should use a similar amount of fuel as an unmapped car. Obviously as has been said if you pin it then your car will go faster but drink harder at the same time.

In the summer, my D5 185 (manual gearbox) can achieve an indicated 62 mpg on an 80 mile run M1, M25, no more than 78mph, no less than about 60mph (speedcams and traffic). Genuine mpg is approx 55 mpg.

As a comparison, similar mileage on reasonably free-flowing A roads achieves an indicated 50ish mpg

D5 185 has to be up to correct operating temperature to get good mpg (10 miles or so), winter diesel will knock off about 5 mpg, cold ambient temperatures will probably knock another 5 mpg off, my guess is that an autobox will knock off at least another 5 mpg.

interesting point Leyburn,

I've noticed my v70 d5 is down on fuel consumption recently - are they less economical in the winter?

Even noticed it on the way back from Xmas on the motorway - car still had some fuel left over after 220 miles on a £30 fill, but indicated mpg was around 44mpg on the computer.

50 MPG out of a Euro 4 is that down hill at 50MPH?

Thats what I would expect from a Euro 4.

I test drove a 2015 D5 V70 auto on a flat dual carriageway and couldn't get it above 35 MPG doing 65 MPG.
