Fuel consumption

[Ottoman]

Thanks Alan.

Yes I have heard from lots of reports that the Mazda figures are a little ambitious. I bought it knowing that it's not going to be the most economic vehicle, especially with it being an auto. I'm hoping it will return high thirties and anymore is a bonus.

Seriously, though, give the Vpower fuel a try. I know it's generally about 10p/litre more than the standard Shell diesel (and quite a bit more than supermarkets). The thing is, it works out about the same in terms of cost per mile, but extends the tank range (that I find useful). I do think it runs better as well.

Thanks Alan, i'll give it a go.

Pleasantly surprised to not find the CX5 in this list!

My car has now clocked 1000 miles so I decided to do a brim to brim check and got 38.5mpg over a variety of driving.

The salesman has told me that after about 3000 miles I should hit the heights of 40-45 mpg. Do you think he is being a bit ambitious.

They do improve with mileage but assuming the same sort of driving you may hit 40, but a bit more on light cruising at 50-60.

Had a remap on mine for almost 2 months now, like for like driving has has increased by 2 mpg around town and on a journey covering over 650 miles I managed 3 mpg increase, of course not everyone likes remaps but I have always been a fan as long as its not tuned to destroy itself.

Unavoidably, for the past few weeks my driving has been restricted to a mixture of town, countryside and the odd few kilometres on dual carriages - but no motorways. Over this period the consumption appears either to be pretty much constant or the computer is broken lol. Anyway, in my 2.2 AWD Auto I'm averaging out 7 litres/100km or 40.35mpg.

I had a run down to Cornwall for the Easter break and I did a brim to brim check of the journey down there. With careful driving and at speeds not going over 75mph , I managed 44mpg but it did feel a very long journey.

I did an overall check when I got back home and over the whole trip I managed 38mpg. This included going up and down those long steep hills and also not being as conservative on the way back.

I am guessing these are common numbers.

I got 39.8 and mine has a remap, same as you was pretty conservative for the first half of my journey but the rest I got bored and made progress a little better,  being the 2.2 AWD isn't particularly economical

Just had a week in Cornwall and according to the trip I averaged 43.1 mpg going down there and 40.7 mpg coming back....313 miles each way (2016 petrol) quite pleased with that.

43.1 mpg going down there and 40.7 mpg coming back

That's the difference between going downhill and uphill, then...

I found 2 reports online about real world NOx and CO2 for diesel. Both published by ICCT.
These gave Mazda a typical CO2 of about 40% above the official data. Among the worst tested.
At least the NOx is relatively good.

I was chatting with the sales staff in my local dealer on Friday and allegedly there are plans for world wide legislation to make manufacturers actually do real life mpg readings. Exactly what is involved I can't say, or what body would be overseeing the results. But it would mean testing a car as it would be driven on the road. Not stripped down on a carefully prepared track. 

That would prove interesting.

Interesting. I also had an X-Trail from 2003-6 - the earliest variant with the Renault diesel engine. I was averaging 41-2 MPG and the front tyres did 45000 before being changed. Never did change the rears - it went back to the lease company at 80000. At 32000 on the CX5, the N/S/F is approaching the wear indicator, but the others aren't too bad.

Not happy with the fuel consumption of the CX5, though. Their real world figures have a much larger variation to the official ones than most other marques. And I still find it hard to believe that they are allowed to test the 150HP version and publish those figures for the 175HP as well...

  I have a CX5 Sport nav Auto  2017  AWD and is returning around 38MPG around town . Its done 3000 miles my old 64 plate done about 35MPG that always  had 5W30 oil on the 3 oil changes. but my !7 plate is running on 0W 30 and with nitrogen in the tyres not Air from new. makes a bit of a difference .
