What happened to the old fashioned remedy of a gallon of paraffin in the tank.

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 Tell someone you love them today because life is short. But shout it at them in German because life is also terrifying and confusing... |

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 Tell someone you love them today because life is short. But shout it at them in German because life is also terrifying and confusing... |

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 Tell someone you love them today because life is short.

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

Mine are the same - at 15 and 17 they wear what they want - the only control I have is not driving them
Hope he has fun Tell someone you love them today because life is short. But shout it at them in German because life is also terrifying and confusing... |

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. Glyn |

I'm reliably informed - by a mate who just left the Spanish oil industry..... Spanish winter spec diesel.... -4 cloud and -10 CFPP for dedicated (single company) oil storage, or -12 CFPP for co-mingled (more than one company chucking stuff in same storage tank). In the North of Spain some companies marketing spec (not the law) is -14 CFPP. All figures are worse case, so you would normally expect the product to perform a bit better. Jon - 110 td5 [sold]. Currently Defenderless. |

'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. |

Smaland, nice! GF is from Stockholm, we sort of life between there, Amsterdam and London. Bought the Defender to bring back to Sweden one day. Was thinking of "winterproofing" it beforehand. Do you run pre-heating on it? |

interesting thread - but still don't know how cold a defender* has to be before it refuses to start

Also, please remember as temperature drops, viscosity of oil increases and output from batteries decreases which will both make starting engines more difficult. Cold weather is notorious for finding batteries which are not in best state of health.
