Default MPG so far from a 1.2LT

Hi All.

I am a little dissapointed in the MPG of my spark, it sems to be no better than my old aging Nissan Almera for local use. I have had a few long runs of around 200 miles in each direction and tried at different average speeds.

Normal day to day use gives me a around 38-40 mpg
Long runs of averge 60-70 mile per hour around 46-48 mpg
Long runs of averge 55-60 miles per hour around 56-57 mpg

I have also noticed the fuel gauge is not very accurate, I can cover 200 miles on the first quarter of the tank and the another 150-200 miles on the remaining three quarters. Has anybody else had this?.

Phil.

Yes, gauge not very accurate, mine doesn't move for first 100miles then drops quickly. Miles to go says about 250 with full tank and have got 400 out of it! Even with wider tyres still seems to average 55mpg on a run @ 60ish.
Have found that a/c is still on if you have screen selected and a/c off this affects mpg.

Just used my first full tank of fuel and got 502kms from it. More than a little dissappointed - expected more - as we drive carefully and in Malta Europe, theres no real roads to drive fast anyway.and as with others comments the gauge is near to useless. the gauge drops dramatically once you get to 3/4 full and then worse again amazingly when you get to 1/4 full....drops like a bag of hammers. so on the basis of 502 kms and i am guessing 32 litres - to yellow light showing (i reckon thats 3 litres left) that would equate to 71kms to the gallon. or approx 15-16kms per litre. not as good as the sales lit would have us believe

MPG tests are probably done on a rolling road with no drag. I was told by the main dealer that the MPG would get better after the engine had loosend up, Well its loose now and the MPG has got worse and the car seems to have even less go than it did when I got it(If that is even possible). It will soon be time for its first service and I have a number of things to ask them to check.

You will have to let us all know what you get from a tankfull.
I have had as little as 250 miles upto around 400 from tank.
Do they spec less mpg for the automatic?.

Default fuel gauge

i am finding the fuel gauge absolutely rubbish no point in having it - it is totally useless and nowhere near as accurate as it should be

'13 LS 5-speed & I'm averaging 42 MPG over the life of the car with over 11k on it.

Installed K&N air filter, starting running Mobil 1 at 10k & have used non-ethanol fuel for the last few months. Driving is a mix of highway (up to 75) & city stop-n-go.

sorry to hear all those inaccurate gas gauges out there. Mine is spot on, all the time. I lose a bar every 30miles on long highway drives.
