Less mpg in cold weather?

[maynard]

Is anyone else noticing less mpg due to the colder weather we're having at the moment?

I'm guessing because of leaving car idling on start up with blowers on full blast doesn't exactly help the cause combined with v-power prices gone up recently in line with normal unleaded prices but just seems like its less mpg.

172 getting approx 100-110 miles from £20 of v-power isn't too pretty and it's not like i cane it to work either (5 mile journey), just normal which includes traffic driving.

100 miles works out to being 26 mpg

Was wondering this myself today on my way home, usually average 40mpg on the motorway but its down to 36 at the minute, must be because of the idling for a while on the driveway, or the constant wheel spins gulping more fuel lol

Its due to the cold air, the engine will be keener to drink your fuel

Yes..the air is cooler, meaning its more dense, in turn this makes the combustion/spark more explosive giving the engine a touch more power thus using a little more fuel.

all the horses and nowhere to gallop

Indeed...my works wi 210 brake on run flats is bloody terrible!!

I'm loving the cold weather, the 172 is pulling like a train ATM.

[maynard]

Mines at 27.9 at the moment but went as low as 26 at the begining of the week. As already said probably due to the colder air. Also if your driving in the estates like where i like the roads are like sheet ice everywhere so i never get out of 3rd gear. Infact even the main roads are very icy, only seen 1 gritter on the roads and that was 2 days before the snow even started.

Choo choo!!!

i thinks its also the fact that you drive in lower gears when going down slight slopes using the engine breaking.

 

[JD]

But you also receive more for your money at petrol pumps as the fuel is more dense in colder weather.

 

[m4rkie23]

lol. only slightly.

im getting about 2-3 mpg less atm

I'm getting a lot more than normal. I've been off boost all the time (for a change) so the car actually seems quite frugal at the minute.

 

[Tigger]

You use more fuel anyway as you'd be using more electrics than in normal weather - heat, lights & wipers etc

 

[Brett]

Also you have to leave the car running for a good few minute while defrosting etc.

A cold engine is more innificient too. I'm sure the autochoke will be on for longer too. My 172 doesn't idle well when cold, its very lumpy, i notice this lasts longer in this whether now rather that when its warm weather it idles fine from as soon its started and the high idle is only a couple of seconds.

Managed to get a great 18 mpg today lol

Leave it running stationairy a couple of minutes?
Naah just drive off is the best!

I'll get the same MPG... no matter what weather.

 

[jayxx83]

noticed a couple drop, but on full throttle it feels like an absolute monster!

 

[ibrahim7]

The r26 is drinking fuel at an alarming rate. Can't grumble superb car

 

[Tigger]

I'm getting around 34ish - still about 270-280 to a tank

 

[Gumby]

I get less in the summer iirc as I just wack aircon on all the time when it's hot :/
