Nearly Winter Diesel time

WINTER DIESEL
NR

Basically this explains why you need to buy your diesel for storing and caching in the winter.


EN590

BS EN 590:2004 (which supersedes BS EN 590:1999) lays down the maximum "cold filter plugging point" (CFPP, the temperature at which the fuel won't pass through a fuel filter) for UK diesel. Pretty much every UK forecourt sells diesel certified to BS EN 590.

- for diesel on sale between 16th March and 15th November, the max CFPP is -5 degrees C
- for diesel on sale between 16th November and 15th March, the max CFPP is -15 degrees C

If you've got problems with your diesel waxing, then either:
- it's been a lot colder than you realise
- you're running on summer diesel in the winter
- you're running on heating oil or something else which isn't "diesel"
- your local garage is being very naughty and needs reporting to Trading Standards

Or, of course, you might have bought a stockpile of 2000 litres of diesel back in June when it was cheap ...
