Another question will a full tank do the 500 miles? Answers on a postcard please ^_^

 

 

got 660miles out of a tank recently - max speed 60mph but a mixture of short/long journeys and its an auto :D

Hi everyone,

 

 

 

Another question will a full tank do the 500 miles? Answers on a postcard please :D

if you can, set the cruise control at 68mph......will give much better mpg than 70!..and yes, should do 500 miles on a full tank...didnt read your car details so am assumeing it is a diesel ^_^

Hi gooner,

 

Its because you are carrying all them electrical shop goodies inside your gal, that's why you only get 400 miles per tank :lol:

 

Keep smiling

 

Walz

 

i think you might be right walz :mellow:

 

how did you on down @ smc with this service tech any joy m8

[Guest walz]

Hi Gooner,

 

SMC as a company will be looking at my vehicle later in the month as no one can do that module or make the system work.

 

Walz

[Guest gooner52]

let me know how you get on m8

 

:mellow:

[Bigjeeze]

I still get an average 44mpg - the computer always says it is higher but measuring on fuel used then 44mpg is good. I have had a smuch as 660 miles before the fuel light comes on - but only twice - and then thats driving around 50 - 60mph with cruise on.

 

I find that the MPG doesn't vary too much unless I hit a lot of traffic or do a lot of crawling on the M25 etc.

 

Still damn good for 105K miles!!

 

My Wife Gal still returns an average 40mpg as well with 135K on the clock.

 

Maybe it's just driving style.

 

 

On an even more positive note - Tesco's near me are doing Diesel at 87.9 litre - saves an average

Morning everyone,

 

I filled the Gal to the brim at the start of the journey and i had to step up the speed abit due to accidents and hold ups. At 75 MPH i was getting 38.4 MPG ( trip up) and at 85 MPH i was getting 37.9 MPG (trip Back). I got 310 miles to half a tank which in theory means i should get a good 500 miles per tank easily. ;) .

 

I have been told though that the half to empty part of the fuel gauge drops down very quickly so you never know i might miss the 500 mile target. :)

you could work it out on mpg.

 

70 litre fuel tank (70/4.55) = 15.4 gallon fuel tank

MPG = 38.4MPG (15.4 X 38.4) = 591 miles!

 

so add in your safety margin - in theory you could do 500 miles, and still have plenty of mileage left to find a petrol station :)

 

assuming you actually have 70 litres of usable fuel in the tank!

i'm not even gonna mention the fuel readings we get from the 2.3

[Guest gooner52]

we got 150miles to last

I've just purchased my 1.9TDI Galaxy but my MPG is much lower than I expected..

 

I only managed to get 430 miles on a full tank (probably 20miles or so left when the light came on), making it just over 30MPG.. This is a mix of Motorway driving (80%) and 20% to the shop, city, etc, etc.. I tried hard to watch my driving (used to driving a company car with petrol card, so didnt really care before), but still the low MPG. Probably doing around 80 on the motorway.

 

How can I improve on this?

[Scope]

Just to add.. My Galaxy is an Auto..

[Andrew T]

It would sound about right for a 2.3 though..........

I reckon there can be up to 3 gallons remaining when the light comes on meaning that you've done about done 430 miles on 12.5 gallons which would be nearer 35 MPG which is better but still poor. Are you're using the conversion factor for imperial rather than US gals?(you should divide litres by 4.546) to get gallons).

Are you're using the conversion factor for imperial rather than US gals?(you should divide litres by 4.546) to get gallons).

 

My calculations are as follows:

 

Tank filled -> drove 430 miles -> filled 63 litres

 

63/4.546=13.85 gallons

 

430 / 13.85 = 31 MPG

 

Sound very poor compared to most of the others I have seen (just under 40).

[NikpV]

depends how you drive it - I've managed 650ish miles on appox

[Guest gooner52]

i agree with nik,you will need to drive very slowley

 

to give you a idea

 

you will need a man and a black flag

 

:) :) :) :) :)

I guess i'll have to live with high MPG then. :)

[Guest MATT jr]

IIRC - when our MAF sensor packed in, the MPG & performance went right down!

 

80mph is not economic driving. 55 is claimed to be the best (as the engine is at optimum efficiency)

 

i did a drive on the motorway at dot on 60 mph,, got 45mpg - although this could be a bit knackered due to different pumps used to re-fill the tank.

 

i also had all electrics off radio/heaters/blowers etc, and timed junctions so i never had to stop (when i came off the motorway)

 

MJR :lol:

[Guest walz]

Hi Everyone,

 

I was using cruise control and in 6th gear, i had heating system on auto, stereo banging out and a laptop being charged through a converter so really i didn't do too bad with the MPG - I like my Gal :lol:

 

Walz

[Guest gooner52]

well was getting 36mpg with a average speed on around 30-40

 

very happy with that.. :)

[GalaxyGhiaTD0555]

I still get an average 44mpg - the computer always says it is higher ...

 

Why does the computer give a higher reading?

 

For my last tankful I got an average of 42mpg but the computer said the average was 46mpg. I think the auxilary heater can use fuel that the computer doesn't count, but it hasn't been on that much recently, and anyway surely that wouldn't account for a 10% difference. I got similar figures for the previous tankful.
