Is your Mazda 5 thirsty?
I have a 3 year old Mazda 5 TS2 D with 38k recorded miles.
It looks as though it will be much less economical than my Mondeo TDCi (2 litre)
Mazda now sitting on less than 1/4 full after 350 mls from full 60 ltrs tank.
Someone else drove the first 150 mls so may have been driven hard?
What is the practical experience of others on MPG?
Thanks.

Thanks for that Nick, The low fuel warning light has just come on but it's well above the E mark. A rough calculation would give me around 37 mpg and I had hoped for a bit better than that, however I shall keep an accurate check when it is refilled and try to hit 5/6 as often as possible.
Does yours give a fair bit of road noise on rough surfaces? I feel mine is quite noisy at times.
It's certainly a nice looking machine and quite roomy with the 6/7 seats or the big boot area. It has a tow ball fitted but I haven't towed the caravan yet. I'd imagine consumption will drop substantially with a tin house on the back!

Ours is a sport with the 17" rims so there is a fair bit of road noise. However, since I fitted the new Bridgestone RE050 tyres this has been greatly reduced. These type of cars will always produce more road noise due to the open space but I don't consider the 5's to be excessive.
There's around 10l left when the light comes on. We easily get over 500 miles to a tank, so if you've got around 450 when the light comes on that's be about right.

Thanks again Nick
Hmmm, still below 400 when the warning came on but I can't say for sure the tank was filled to the neck.
When I refill, I'll try economy driving and report back but we are off on hols without the Mazda for the next while so it'll be much later before I can post results.

Attitudes towards ottawa asian escort criticism differ from person to person. Some people will become annoyed if they are criticised and ottawa asian escorts they will try to excuse themselves by all means. Some ottawa escort people tend to be indifferent criticism. They just regard criticism as nonsenses. But still some people ottawa escorts accept criticism modestly and try to find their

Do not forget the DPF
F.Y.I.
My car is a 2008 2.0D Sport and has done just over 17000miles. I typically get about 40-41mpg. My driving is all on single carriageways with a mix of short (8-12mls) and 45mile journeys.
At one time I tried driving as economically as possible and got it up to 45mpg but I would urge caution if doing this. Recently it became obvious I would not get to the second service without an intermediate oil change due to too high an oil level. I blame the DPF regenerating too much due to the economical driving causing the DPF to block up. (See my recent comments on the "Changing oil and filter on diesel" thread). Therefore if like me you do not normally drive at 70mph/2000 rpm for extended periods I would recommend doing this for 15mins (i.e. as per handbook on blocked DPF). Once a week or every tankfill should be sufficient.
On a recent tankfill I decided to see what mpg I got going to the other extreme by keeping the rpm at about 2000. I never managed to get into 6th the whole time and the mpg was 39.2. (Computer figures were 40.1mpg and average speed of 37mph).
At the moment this is only a theory - I will discuss it further with the local Mazda garage when it goes in later this week.
Also another reminder - the handbook recommends not letting the fuel tank go below 1/4. I assume this is to help keep the fuel pump suction clear/positive or possibly keep the pump itself cool (assuming it is located inside the tank).

I'll keep all that in mind. I think the guy who does my servicing has a program to reset the engine management system.
I'm also going to give it a "burn" at 2k rpm to try to clean out the DPF and hope that helps too.
I've just filled the tank and reset the trip but I'm away without the car for the next 6 weeks or so therefore it will be some time till I can check the average MPG. It seems to be happy enough in 5/6 gears at relatively slow speeds but are you saying that will add to the sooty stuff in the DPF?
The first 140 miles after I bought it were on motorway/dual carriageway at around 70 mph so I'd have thought that would have given the system a good "clear out"?
Fingers crossed for better results this time!

So it looks like I am around average. I must say I had expected better than that. I have been accustomed to around the 50mpg mark with various 2.0 litre diesels but I suppose the Mazda is a bit heavier.
I wonder how it will get along with a caravan strapped on the back?
