Mondeo using more fuel

Unless it somehow manages to get the oil up to temperature within sixty seconds, there is no way everything is up to temperature.

That won't help.

I must just pick the quiet bits.

WE WERE TALKING ABOUT THE WATER TEMP.

Very good. You've finally got to the point of the whole thread.

No, really?

Yup.

"it's up to running temperature"

As I have pointed out several times, there was no way of knowing what you were talking about.

Situation normal, I suppose...

:-)

Aye..as usual you're not thinking. The thread was on about water temperature.

It was the thermostat after all. New one fitted, all now as should be. Expansion tank hot, needle in middle and most importantly mpg vastly improved. Must have been faulty for a while, in a year of driving the car the temp gauge only slightly moved above minimum, mpg averaged 37. Last few days I have been getting 40mpg which I dont thinks too bad for a taxi doing round town driving!(and certainly a lot better than the 31mpg I was getting last week). Engine also sounds a lot quieter, the performance is slightly better and the driving is definately a lot smoother.

The message from "Kay" contains these words:

I hate to think how much bore wear you've had in all that time of overfuelling.

But isn't diesel oil a lubricant ?

The message from "powerstation" contains these words:

Ah, I'd forgotten it was a diesel!

Doesnt matter! Ask any VAG Tdi owner who's ended up with oval bores and cronic oil consumption after he failed to replace the injectors when they wore out!

tim..

Don't think the 'stat had been completely broke for a year, only slightly broke. If that's possible of course! I think its been opening not quite fully (hence the needle moving about a quarter from cold) for the last year or so, and failing completely in the last fortnight.
