I'm just wondering what mpg other boosterjet vitara owners are getting  Question
Since I bought my vitara s at the end of October, I've struggled to get more than 36 mpg in my daily driving!
My previous s-cross 1.6 petrol used to be a constant 42mpg.

I have the 1.4T Allgrip and get around 23mpg in the city (stop and go with hills) and around 38mpg in highway (doing about 110Kmh)

I've had my Vitara S 1.4T Allgrip Automatic since end of May.
The first 16 000 km with higher temperature and summer tyres it was 46 mpg.
The last 5 000 km with lower temperature and winter tyres it's 40 mpg.
This gives an average of 45 mpg over 20 000 km so far.

We've owned ours since June 2017.
1.4 S Allgrip Auto.
Tyres set to comfort mode, normal Autobox use - no Sport etc.
40 MPG, mainly commuting into Leeds with the odd trip into the Dales, I'm a 'sedate' driver, my partner less so, scares the s*** out of me sometimes!

I agree, you wouldnt own a dog and not expect it to bark 8-)

2017 S Comfort mode with roof bars 24/7 17" Contis 46mpg and with the 16" Yokohama G015's 42mpg but a far better ride/grip

Sport mode and using the cars full functions low 30's

thanks for the feedback everyone!
I'm wondering if an injector cleaner in the fuel tank and a good run might help to improve my mpg ?

There are a few tips for getting better economy, without having to drive around at 20 m.p.h.
Do not race away from a start, change up the gears early, around 1000 r,p,m,, and anticipate the road ahead by minimising the use of the brakes , and cruising to a stop rather than braking.
Do not use cruise control on hilly dual carriageways; take advantage of downward slopes by increasing speed to help you over the next hill. Inflate tyres by a few pounds p.s.i. will help economy.

Thanks Karl, I will give the super unleaded a try next time I'm due for a fill up.
I'm wondering if the new quatrac tyres have had an impact on the fuel economy! Plus the hills of Sheffield don't help.

I think the fuel economy is really good on my 1.4T allgrip.

If my missus uses it to go to work it does dip to 32-36 mpg, however she only works 1.7 miles away from home, so the engine hardly warms up and is to be expected.

When i use it to go to my work 19 miles away i get 42 -48 mpg, a good mixture of twisty Back roads, A roads and dual carriageway.

I have seen 52mpg on a steady 190 mile run from Norfolk to Shropshire.

Strangely when I engage sport mode ( which i do often ) i find that my fuel economy improves and the car responds better, i think sport mode should be the default setting !

However that was mostly on the OEM 17" Conti Eco 5's at about 42 psi in Eco mode

Now running 16" Winter tyres on Comfort Mode 32psi. Refuelled at work last night ( which resets my fuel figures). 19 miles later just checked and I have 42.1 mpg on the info display this morning.

The best that i ever got from my Diesel 1.9 4x4 Fiat Sedici which this car replaced was about 48mpg i never saw 50+ with that car...

I am a very happy Vitara owner cheers

Errr I feel stupid now....
I never realised that you are supposed to reset your average mpg by holding the right pin in when mpg is displayed.
Now getting 46mpg

I have been running my vitara on eco for a few weeks, several mpg resets and no better than 39mpg. Like you thought it may be the tyres i have fitted Yokohama G015
Last week travelled from Shropshire to Oxford on Eco.....39mpg. Changed in Oxford to Comfort and exact return journey got avg 46mpg????

Hi lotusteve, I don't worry about the mpg now but I think the idea is that if you have a journey planned you reset the mpg to give you an average over that journey.

Use something like Fuelly* to work out your fuel consumption. The OBC on my vehicle is very optimistic when it comes to fuel consumption.

*other apps are available.

Ours is an auto and returns 42 mpg on a reasonable journey, 37 mpg in the city.
Never trusted the dash readout, go to same pump at same station, set trip to zero and fill to the neck, return when ready for more fuel then work it out from the receipt and trip readout.

I'm a little confused about the MPG reset and when to do it?

Should you not just leave it to give you an indication of the cars average consumption over the time you own the car?

I can see the point in resetting to measure the MPG for a journey but how long does it take to get the average?
My wifes little Hyundai i10 takes an eternity to level out to the average MPG on a longish trip.
It's usually over before it's even got to the average!

I reset my average usually after none regular driving such as leaving the car ticking over on the drive to clear frosted windows or say I have had enthusiastic use of sport mode.......both of which I have found can drastically alter your average mpg

The average shown is of course the average since you reset it. If you reset it just after a cold start of the engine and before the car starts to move that is included in the reading. And for those few moments the MPG of course is zero (0 miles/gallon). That's why you think it takes a long time. But it really is the average (apart from that it might not be 100% correct).

I reset mine when ever I fill the tank. I also calculate the correct MPG and I save it in a spreadsheet. The car shows about 6% better MPH than correctly calculated. After 54 000 km it's 6.3 l/100 km or 45 MPG.
