There's a discussion on the Defender forum about when fuel is waxing etc, some useful info there:

Good read RRUK

Iirc they don't reccomend mixing petrol in some diesels these days but not sure if the tdv8 is one of those affected..

With modern high pressure diesels the tank fuel should warm/thin after a few minutes of idling as the extreme pressure heats the fuel a bit before returning any excess to the tank some cara have fuel COOLERS fitted on their return to tank feeds  FFRR MY06 facelift With TDV8 Alloys Zeros/ATR's
Mantec Sump Guard, Rigid Load liner, MY10 BT upgrade.

Thanks - I don't fancy petrol in the diesel with the TDV8 - I hear that modern high performance engines really don't like it

The Defender thread is good - they even have their own Mick !!!!

I'll stick with the Wurth additive & local diesel I think - the additive turned up today so I'm all set

Mine unlocked and started fine at christmass, but then went in to limp home mode which can only be reset with OBDII.
Allthough the car was totaly covered with snow it had not been unduly cold, the garage that came to my rescue confirmed that there had been a national problem with inadequate addative by the fuel companies and it had been his 5th call out that day.

What you really need is a holiday down under...cooled down a bit this week....only 31 c today.

wind chill can effect anything.
in humans, the biggest causes of the chilling effect are the convection and moisture evaporation.


with inaminate objects.....like a car...all wind chill might do is cool the object quicker to the ambient temperature. Once ambient temperature is reached, the temperature will go no lower.

It will if the sufaces are wet and latent heat comes into play.

in sub zero the surfaces will not be wet for long, so the inaminate object will reach ambient temperature soon enough.
the wet will either evaporate and the surface will become dry....or the wet will freeze (oh! latent heat GIVEN out when the water freezes !)
latent heat usually turning from water to gas absorbs energy, giving a cooling effect. So conversely, as the water changes state into a solid, it gives out energy. Is that what you meant ? Perhaps not, but that is the physics.

Not really.
I was thinking of road vehicles running on salted roads where the fuel lines and tanks etc can get below ambient temperature by virtue of running on wet roads or snow covered roads. Such that in winter they come to a grinding halt due to diesel waxing at ambient temperatures somewhat above -15C , the point to which diesel in the uk is protected from waxing in winter.
Given that the ambient temperature is well above the waxing point the only way the diesel can become colder is due to latent heat loss due to the wet surfaces which generally appear not to freeze as you would expect in winter due to the relatively high salt content of the water / salt solution wetting them due to spray etc.
Seen it happen many times when it really shouldn't occur.

The previous poster was correct. Only humans feel "windchill". It is a theoretical measurement whereby the temperature actually feels colder due to wind effects on human skin in a cold climate etc.

Easy way to explain. On a cold day put your arm outside your car window when travelling at speed. It feels colder than when stationery, but the outside temperature is actually the same.
