Here in Munich we are expecting a "warmer" spell over the next week of -15 at night and -5 during the day. However, as it warms up the breeze picks up and it seems colder

Kitzbuhel, Mayrhofen etc. should be a few degrees warmer.

Good news is that the Austrian mountains often get quite sunny and the instructors are usually very careful with the kids.
Often the "exciting" temperatures you hear quoted are at night in the coldest, most miserable holes...

If your son layers up ("onion technology" they call it here) and is active he won't have problems. Just try to make sure he has a good hat (fleece is best), decent-sized goggles (not sun-glasses) and a neckroll (sort of a tube-scarf you can pull up for that "bandit-look"). Sorry if that sounds patronising but you wouldn't believe what some of the parents here send their kids out in



p.s. I'm still learning how to dress - normally I would wear a t-shirt and a fleece and be cold outside even with a coat. This year my wife forced me to smarten up a bit and wear a (thin) shirt under the fleece. It's amazing! I can practically walk around without a coat just because of one little cotton layer

Thanks he has all the gear as he is a regular skier it's whether he uses it.

Aha! Just checked back with the German forum and Aral Ultimate Diesel goes to -24 minimum and ADAC have tested it to -33.
Shell V-Power is only down to -20.
So if it gets any colder, I just have to drive a lot to get the Shell crap out of my tank and refill with the good stuff

Aral gets my vote. Last winter I was in Austria (Up the Stubai Glacier) and we were getting regular temperatures of -20ish without wind chill and the Defender started every morning without a problem.

I got caught out here in southern spain (in the mountains) 2 days ago,
we hit -9 at night (for a couple of nights), 110 wouldnt move, probably waxed up...would idle at about 1k, but no more.
Eventually managed to get it into the sun, it warmed up, then would go, albeit with some initial misfiring.
My FL wouldnt even turnover.

Lived in switzerland for over 9 years, never a problem

so i will now always park in the sun when its going to get cold, im assuming they dont bother using winter fuel here.

That's where it all confuses me. Apparently paraffin crystals forming in the diesel are the problem but people say add paraffin to the diesel. Paraffin seems to be called kerosene as well but there are different grades (e.g. jet fuel c.f. heating oil).
Some people differentiate paraffin and paraffin wax

It's all so confusing

'Paraffin' seems to be a long adopted marketing name (probably wrongly) for a clean burning premium Kerosene used indoors in lamps & stoves. As its a clean burning fuel, no flue is needed on the appliance. It's normally dyed Blue or pink/purple.... Boom Boom Boom Boom...... let you finish that one...

'Kerosene' or 'Kero' is what people in the UK burn in their oil fired heating systems. This stuff is very pale yellow in colour but tends to be marked in some way (in UK it's an invisible tracer) to deter people from blending it into Diesel. It's not as clean burning and therefore requires to be burnt in a closed environment in an appliance with a flue.

Jet fuel is essentially Kerosene. I should know the exact differences given that part of what I do is sell this stuff for a living but simply it either meets the stringent Defence Standard or it doesn't

Paraffin waxes are left in diesel as it contributes to a better Cetane value. Kerosenes have solvent properties so can be added to diesel to dissolve the wax and improve the cloud and CFPP, hence Micks comment..... Parrafin or Kerosene would do the job perfectly but are both illegal to blend into diesel in the UK as road fuel as no duty would have been paid. Imagine this is fairly consistent across Europe. Adding a kerosene would depress the Cetane but in extreme cold, you just want the b*gger to start and run

Never used an Anti-waxing product myself but there seems to be a few on the market. Wurth do one that makes claims of protection down to -30. Probably stick with the Aral diesel though if it's typically reaching those sort of levels already. Jon - 110 td5 [sold]. Currently Defenderless.
