Fuel consumption

[Anchorman]

No regrets its a good car, only the entertainment and nav bugs are the main issues, having said that Mazda cars do appear to have more problems that other jap cars i've had.

Have you got the latest software?  Mine has been done a couple of weeks ago and its fine now.

I've installed 511, but not 512 as it offeres nothing for me. My BT problems are now resolved since the BT module was replaced.

Your satnav runs BT does it?

Hiya all, I'm posting in the correct thread after posting in oil levels, it's to do with the top grade fuel versus supermarket fuel, my plan last Thursday  was to drive 380 miles on a full tank of asda petrol and see if it was much different to shell v power. Anyway I normally use v power, so when the day came I realised  I still had over half a tank of v power,  so I just topped up with 29 ltrs of asda fuel, didn't reset avg consumption. Well the asda fuel was 99.7 a litre, at bridge of dee aberdeen, when I needed to refuel on the m6, I put in BP ultimate it was £1.25+ a litre, and the avg comp was still reading 38mpg at the time, so at £1.12 a gallon dearer meaning you can get a extra litre of the supermarket fuel it kind of negates any milage bonus of using the dearer fuel. Obviously motorway forecourt prices are the dearest but sometimes people do have to use them. I'm no longer going to mess or experiment, one thing I have realised having this car for near on 4 years is how good the consumption  is up to 70 mph, but any faster it dips really quickly.

It's easy to run away with the idea that high grade fuel is all about mileage but for me that is only a bonus. The main reason I use it is because of the benefits in keeping the injectors clean, the EGR and the cat.  Now see, you've got me in trouble so to keep the thread on topic I would summarise by saying it acceptable to expect other benefits than reduced consumption.

I agree anchor, I use it for the same reason now, checked out shell v power on website, 25% more anti friction additive now in the v power range over the old V power range

Latest data after a couple of weeks on one tankful.  I had 661.6 miles on the trip, and the pump took 50.38 litres, 11.03 gallons.

According to my calculations I got 59.96 MPG on this, but the readout gave me 63.9 MPG.

Either the computer is flawed, or the odometer was 43.21 miles short!

Hi
  I am new to the forum and a recent  owner of a 2013 CX-5 2.2l sports nav from a approved showroom.

I have had the vehicle for almost 4 weeks now and had been driving it with much care.
I am only getting a economy of 43.8 mpg after much careful driving clocking around 1300 miles. 80% of the driving was on motor way keeping the speed between 70~ 80 mph

I just want to check whether I am unlucky to have picked a used car which gives much less mpg than what is advertised. is there any one out there who is getting around 50~60mpg

[twabrigs]

Welcome hazzy - I usually get 40mpg in my 175ps, currently it's reading 43mpg but that's unusually high so I suspect your 43.8mpg is about all you can expect.

Those figures are okay for a mid-large SUV 2.2 diesel but nothing like the claimed Mazda figures.

[ROCKETRON]

I Usually get around 40-43 from an auto 175 but i find it can be substantially improved if you only do 50-60 mph. if you do 70 mph plus then it uses disproportionately more ,probably down to the aerodynamics as it is very high.

[xtrailman]

With the warmer weather my read out is around 42.5mpg, less the error makes it 40mpg.
I have had the read out as low as around 38mpg, so less the error makes it poor IMO at 35.5mpg.

Towing i recently got a read out of around 27.5mpg, less the error makes it 25mpg.

My last 175 manual returned around 41 to 43mpg locally, less the 2.5mpg error.
Twice i had 55mpg on a run off motorways.

And twice had a read out off 34 mpg towing, so still over 30mpg which i think is good.

[hazzy]

Thanks for the replies guys. 55mpg sounds good Is that when you were almost between 50 to 60. Yes I have noticed the mpg goes up between 50 to 60

Update on mine; 43.5MPG true figure after 17k miles (trip computer average is 45.5, so still running at +2MPG above true). That compares with an overall average of 41MPG on my previous one (same model) over a 70k mile life.
