Id expect more than that on that distance.

When did you last reset the trip?

About a month ago I could reset it again but I should think it will be the same or worse

I have a 1.6tdci 90bhp titanium. My commute is about 80 miles per day with 75-80% of it being motorway. I use cruise control at 65mph and only average about 50mpg and get about 400 miles on a tank. I think this is poor, before I bought it I read most people could average about. 60mpg and get 500+ miles on a tank. My gf's 320d BMW is equally as good on fuel and it's got 177bhp. It's due a service so hopefully they can look at the engine management and hopefully improve it.

My last car was a mini cooper jcw with 200bhp+ driven at 65mph on cruise I could get 35-40mpg

I would expect better than 50 with motorway driving.

My dad's 207 gets about 60-65 I think with a 28 mile each way commute, 90% motor way driving and thats with the 1.6 hdi 110. (Same engine as 1.6 ford tdci)

It would be interesting to see what differences it makes if you stuck to the big branded stations for a few fill ups.

I've known supermarket fuel to ruin a fuel pump in a diesel and more than one mechanic I've spoken to has said stay well clear of the stuff, too much water and the car has to use more to produce the same "bang" in the engine, so it can be a false economy.

I only use Shell (it the only one for miles and I don't travel far for work), and as said previously, I will get 45mpg from a 2 mile journey, not even driving that economically.

Can soon find out I will just stick to the main brands and see what happens

I think some have already said they reset trip at every fill-up, but i have noticed that if you don't, then the car's trip computer is very slow to react to change, so if you want to get an accurate reading on a journey its best to reset before hand, if you haven't already done so recently

I can tell you that measuring over 45,500 miles (101 fill up and measurements) my trip computer mpg is -3.28% accurate. My real average is 57.75, computer average is 55.9. (I reset my trip computer on every fill up and that 55.9 is the average of the 101 readings)

I think some have already said they reset trip at every fill-up, but i have noticed that if you don't, then the car's trip computer is very slow to react to change,


Correct - the longer you leave between resets means it is calculating the mpg using a greater amount of data. Therefore need a higher number of values either side of the average to affect the read out. E.g. if your average was 55 and you hadn't reset in a while you'd either need to floor it (getting 10mpg) for a bit for it to bring the overall average down.
