Massive Drop in MPG

[Cupra Kid]

Noticed in recent weeks i have had biggish drop in mpg from my car, its doing between 6 and 10mpg less on a tank. wondered if it may be due to the recent temperature drops? Also filled up with ultimate then went back to normal petrol so wondered if this could be the problem?

Any help appreciated

Mine seems to have done this since the cold weather began - I ask my BF this (typical girly question) but he seems to think its the same as nothing has changed on my car at all....

Another reason why Summer is far better than Winter.....

On cold start you run choke for longer therefore until you get up to reasonable operating temps you'll be pumping in more fuel. With the cold dense air the mix will be richer, but the car will run quicker though!

Cheers for the information guys, will stop worrying about it now.

ur car should be quicker in winter (in theory) because the air is colder and denser. but also use more feul. remember ur also using ur lights and heaters etc. more.

Paul - might be worth checking the crankcase breather pipe - I had a drop of about 5mpg when mine split in two a while ago.
