Technical Sh*te MPG. :(

Right first of all let me say the mondeo tdci is a decent lump and when cruising is indeed a frugal car for its age

Thanks but I'm more than aware of the mondeo's capabilities.

but to use a trip computer reading as a fact of
your cars mpg is not a good idea as they over and indeed can also under read at times. the only way to know what your cars real mpg is, is a brim to brim refill/:bang:

Who can afford to fill up a car these days....plus more fuel = less weight = less fuel consumption! Best way is to put a litre of fuel in a empty tank until it runs out.



Doblo's are too square and van'ish for my liking. :p

I haven't touched/used/looked/reset trip computer. I work out mpg via millage > per gallon per fill up then my app averages it out over the previous data inputs :)

But unless you brim it to fill, the same point every time, you have no way of knowing how much fuel you've used to the number of miles you've covered. Putting in 20L each time doesn't mean you've used 20L as there could have been 5L still floating about in there, or on the tank before 10L, and you've no way of knowing how much is left in there short of running dry of fuel, or brimming the tank.

! clearly you are not! otherwise the one thing you would not do on a mondeo for sure is purposely run it out of fuel! in fact its a daft thing to do in any modern diesel with any sort of mileage under its belt . I would kindly suggest nobody do that method to work out their fuel economy on a common rail diesel.

Whys that then :confused:

The high pressure fuel pumps don't like it and cost mega money to replace.

Anyone seen the European commission's report on official mpg figures? Whilst the testing is done on a rolling road in front of independent inspectors, the manufacturers have to calculate drag and rolling resistance figures to factor in mathamaticly. Turns out they have been cheating by taping over the panel gaps, using a low friction road surface, smaller wheels and even running the cars down hill. Add that to the fact that the cars on the rolling road have fully charged batteries, none of the electrical accessories are used, the air con stays firmly off and they pull out the fuses for non-essential systems and what chance has anyone ever got of matching the figure? The European commission have concluded that the cheating has knocked 11% of official fuel consumption and co2 figures.

Finally, the test cycle itself is far from perfect. It is meant to represent the whole of Europe, our roads are poorly designed and crowded so we will use more fuel than the average. Also the cycle is surprisingly short, taking in a limited range of speeds and accelerations. This allows the manufacturers to optimise the gearing for a few specific speeds that in reality you don't always drive at.

The topic here is (GP) petrol not diesel.

The high pressure pump uses the diesel as lubrication plus mondeos are a pig to start when empty even changing the fuel filter you often have to use a mitivac.

Sorry assumed you were still referring to yourself with regards the running the car dry method, although even with a petrol engine its not going to be a very accurate average mpg reading is it one litre ? about 10 miles with already well warmed engine.....a lot less from cold....
 
I am currently averaging about 30mpg with my 09 1.4 active sport 8v.

However, that is alot of start/stop driving where i drive. speedbumps/potholes all over the place.

Thanks,
Michael
 
I own a 1.4 8v active sport and I get around what your getting and my driving is normally back and forth to work. To behonest I do get good results though when I hit the motorway around 45-50 mpg :)
