Its winter.. lower mpg expected ?

Petrol and Diesel operation are two completely different beasts in the cold though ben, so our diesels will lose a lot more if only doing short runs in this type of temperature.

Postie - It sounds like you are just getting a little oil past the rings when it is this cold. The material will contract a lot more than usual so when the engine first starts and begin to get warm there is a larger clearance past the rings than there should be. Once up to temp and the materials are warmer they will expand that little bit and close up the clearances. Nowt to worry about.

thanks for that Agreeable Slick,

Oh p.s. I should mention, just keep an eye on your oil level, it will probably need topping up what with the cold temperatures dragging on so much.

If you do drive it from cold, let it get to temp before sitting on the turbo as that will definately not help.

thanks.
i have been looking at the temp but since the cold weather started it does not get to 90 until ive done about 10 miles of just very careful and slow driving it was fine before the cold only took a mile or two to reach 90 on temp.
since the cold weather started i have just let the car sit there running to de-ice the windows which means its running for about 5mins some mornings, now i have said that some one is going to say i should not let it sit there on tick over for so long as its not good for some thing on the car.

Well, running an engine when it's sub zero material temperature is not good for the engine, but what are you going to do? - only thing you could do is put it in a heated garage overnight or wrap he engine in a heat blanket, and lets be honest that's not going to happen is it.

Like I mention, try to keep it off the turbo as much as possible, as that will help the engine cope without the sudden ramp up of speed when the turbo kicks in.

Agreeable slick you are one knowledgeable (SP) fooker mate

My 1.9 gt tdi 130 dropped from 69.1 to 64.4 after the cold weather set in and fitting bigger/wider alloys

Cheeky fooker i'd love to get that kinda MPG i've never seen that owning the car for over a year
What kind of driving do you do to achive that?

[Gareth F]

Driving 60mph on the motorway using an asda lorry to set the pace 

Mine can easily acheive it, just feather the accelerator when needed but as soon as you hit traffic thats it

City driving i get about 38-40 over a month due to sitting in gridlock traffic with constant stop starting!

i looked in the vw manual in the glove box and it says that your fuel consumption is double until the cat is up to temperature and it takes approximately 4 km of driving to warm it up.

perhaps its just taking longer to get the temperature in the cat. since reading that i never accelerate hard until i can see the water temp gauge start to move. and it doesnt budge for longer during these cold morning we have been getting.

That doesn't make sense, why would the CAT have any effect on fuel economy? It would obviously have a massive difference on emissions but I can't see what the CAT would have to do with fueling?
