This even more just in - the weather thread

Detonation, knocking, pinking... All the same thing; all bad.
Is "waxing" a problem for diesels in your frigid winters? Wikipedia tells me that the USA and UK (like most places that experience cold weather) have standards on the fuel supplied during the winter months (even Australia does, though it is not a big problem here). There are, however, questions about how applicable to modern diesel-engines are the traditional tests for waxing temperature.
If I drove in a place with cold winters, I'd look carefully at the filter heating in my chosen car. Modern diesel engines can be damaged by some of the "old tricks" used to prevent waxing, like adding kerosine to diesel (which is actually illegal in many places, but blind eyes are sometimes turned).
pwhodges:
I have driven diesel cars for thirty years, and never experienced waxing. Before I could drive (e.g. in the cold winters we had in the 1960s) I remember seeing lorries stuck at the side of the road because of waxing. I presume there are seasonally suitable amounts of additive included in what comes from the pump, and would never consider adulterating the fuel myself.
"Pinking" - ah yes, I'd forgotten that one; but then, it's so long since it mattered to me (see remark about diesels above).
bhtooefr:
Gelling is the term used in North America, and it is a problem if you get fuel in the southern US and then head up to the colder northern parts of the US or into Canada, or if you last filled up before October or so, and now it's deep winter.
And, the anti-gel additive used by the fuel suppliers in North America is diesel #1... also known as kerosene. Lubricity additives are added to offset the reduced lubrication, but still...

from my truck when I started up at 0700.
E stands for EAST, the direction I was facing.
and yes, this translates as -20 C.
