Why would you need it in the UK? Pump diesel doesn't go waxy at UK temps...

Can't say that temperatures ever got low enough, even last year, in the SE to cause problems with diesel wax formation. If you live in a colder part of the UK, then it's an inexpensive way of getting peace of mind at worst, or a useful addition if it's a problem you have encountered in the past.

If you run veg oil through winter though this would be very handy!

It does at around -15 degrees. Not uncommon in may parts of the UK last winter. If your car is sitting on frozen snow and the air temperature is down to -12 and below then waxing can certainly occur.

Caused me and many others difficulties last December (and in Jan 2010).

There were suggestions the refineries hadn't winterised their fuels but they would hardly admit it, would they ?

It did last year, and early this year. UK winter diesel is only rated to something like -12 or so.

Interesting - went down to -17c (very exposed to wind chill as well) here and there were no problems reported locally.

If the problem was so widespread at a refinery level it was very poorly reported?

I've used this stuff before - but I'm talking about the late 1980s after I had a Pug 305 GRD wax up. They had a glass filter and you could actually see the wax formed in it, it was like petals. Took a lot of heating up to melt it all. This was the one and only time I've seen this happen.

Never ever had to use additive since - not even last year or the year before - and winters don't get much worse than that.

Do you have a reference for that? I'm trying to find one for Shell or BP?

Not sure where you are in Yorkshire but they had trouble at the Land Rover Experience Day at Coniston with diesel freezing.

We had quite a few customers who had problems with diesel freezing last year, tended to be those who had not filled their cars up recently and weren't running 'winterised' diesel. Certainly my diesel never had any issue's and we were hitting nigh on -20 at one point, but mine does get re-filled regularly.

And petrol is handily available to purchase at most places that sell diesel

Pump diesel changes to "winter grade" at the end of Oct...so no need for it where I live (South uk).

those Up North might benefit from it though yes

OP - was it one garage that you had a problem with or multiple?

Just thinking that one, low volume garage might have had summer diesel for some weeks into the cold spell?

I just don't think it was a widespread issue at the refinery level - or you would have seen the hauliers out in force and causing uproar - which we didn't?
