MPG problems

[richard2k84]

My MPG is crap. I know its cold so shouldn't be as good as normal. But the car is down to 38MPG which is crapfor a 1.2 which should be 48MPG (so the book says)
I have changed air filter. Pumped up my tyres to the right psi but still no joy. what else could be making it so poor. Should i check if all pipes are right and not letting out any air along the way, or are there any sensors i need to check or maybe replace. It does have a new MAP sensor on as had to change this with a new wiring loom
Cheers

how do you drive?

 

[richard2k84]

I dont rag it around much. I do get alot of traffic coming and going to work. It's a 45 mile round trip, so i know that does not help. But even at weekend aftre i just fill up the MPG is still poor. All i can think off is to change the oil, and maybe the cooleant. Not even sure if that will help tho.

 

[Dan@SJM]

well 45mpg would be possible if its not going above 3krpm etc,

 

[richard2k84]

I am still running short on MPG then. Was just thinking if there was anything else i can do to try and up the MPG

 

[Dan@SJM]

dont brake as much, think ahead, try and use the engine to slow down as much as possible, dont go above 56mph, avoid stop start traffic, etc etc

maybe check the carbon canister that might cause a dip in mpg sn commonly broken on the 1.2 iirc ,mine was broken anyway!

OK dont wish to sound dumd, but what is the carbon canister and where will i find it (on the car).

i get 38-42 mpg in my clio, and i'm on teh motorway all the time, but i blame it on me doing 85/90 a lot. I finish work at 12:30am, so the motorway is always empty.

Its in the drivers side behind the arch liner near the front bumper form memory or the other side in the same area.

Cannot realy miss it.
