Fuel consumption

[brian]

Hi dg70

I'm still getting used to the sixth gear so some of it is probably down to me but I calculated the figures on a full to full tank and it actual came out at 37.6 so now I've reset the trip and doing another 200 mile round trip this weekend we'll see how it goes

[dg70]

I tend to just use 5 gears anyway, usually switch from 4th straight to 6th. I very rarely use 5th gear unless I'm overtaking or going up a steep hill. 4th gear will get the car up to a reasonable speed where 6th can take over without any issues.

19000miles on clock now, avg 37.6 mpg on trip computer, using v power, but when we had our heat exchanger changed out last year it was dropped off with a average of 25 or 27 mpg reading, I left it for a good few months and there wasn't any real change. then decided to reset and it started reading 35 avg.  so all I'm saying is don't trust it ( computers ), the tank brim method is the way I do it if I really want to know more precisely. After chatting with Caldean I have tried to drive more economically with good results mainly by being in the correct gear for the road condition and speed.

I think I've solved the fuel consumption enigma I've just achieved 50.4 mpg on a 100 mile trip all I had to do was travel up the M3 between Basingstoke and the M25

Great.  Limits your holiday destinations though

Isn't that section mostly roadworks with average speed cameras at 50 mph? It does wonders for mpg...

Just done second trip to Inverness.  Average speed cameras and traffic kept the speed down to between 50 and 60mph, other than a five mile stretch at 40. Managed 49mpg until I got to the motorway, when all my good work was undone, finishing the 125 mile trip on 46.6 mpg. It seems consumption plummets if you go over 67mph, but under that and it's very impressive for a petrol. Sure don't need a diesel....

Ist proper trip (only done 390 miles total) round trip from Milton Keynes to Lincs visiting family.  Journey mostly A1M and dual carriageway, with some local "B" roads at either end and a short local trip thrown in for good measure.  Did a steady 70 on main part of journey - but needed to put my foot down getting past slow traffic in Lincs.
Even so managed 50.4mpg, so more or less living up to expectations!
Got another / longer trip planned for next weekend = going up to Northumberland, so will get a better feel from that journey.

I'm on 42mpg average at the moment, all A,B roads with some town driving.
I have had 55mpg on three occasions but only on A and B roads.

Motorway driving its poor dropping below 40mpg unless there are road works with 50mph limits.
IMO the Mazda needs another gear, which is only practical in an auto.

You don't have 6 ? ?

As BigAl has previously said, don't be fooled by the on-board display to work out your MPG.

I reckon mine is about 10% out, i.e. computer says 40mpg, actual MPG calculated by using a mileage / fuel consumption spreadsheet only 36mpg.

Do the maths for yourself.

Let's hope they haven't porked their emission figures as well..??

I'll probably do a brim to brim a couple of times with the new car when It arrives.

I always use to use that method but gave it up when I tested an Audi A4 I had back in 2000, that was only around 1mpg high consistently with the average read out, near enough for me.

I've since read the CX-5 is around the same, but I haven't bothered to check.
My fuel returns are about the same as Honest John and Whatcar say with there real and true mpg figures, and I only use supermarket fuel.

Yes but I tend to skip 5th gear altogether. Very rare that I use it

The question was directed at xtrailman   I used your statement as a reinforcement that there is a sixth gear.

[xtrailman]

Yes but top gear is low for motorway driving IMO.

Putting 7 gears into a manual box could be more trouble than its worth, but could easily be done with an auto transmission, CRV now has 9 gears, the new X1 8 gears again.
