Normally, when doing day trips I don't bother, but this year we're spending a few nights up at Mt Baw Baw. I normally head up via Lillydale / Nojee. Any ideas if there is somewhere I can get Apline Diesel on the way?
If you are not in an alpine area but have abnormally cold weather, a diesel blend may provide some relief to lower the cloud point. Heating oil (duty paid at diesel rate) is an effective blending agent and your BP supplier can provide information on how to perform this safely, but typically would involve the following:
Heating Oil at 25 litres for each 100 Litres of diesel, or
kerosine at 5 litres for each 100 litres of Diesel.
Normal Diesel can wax up and clog injectors / fuel pump at prolonged cold temperatures (say 0 or colder). Essentially the car wont start and you need to heat up the fuel system to get it working.
I wouldn't worry about a day trip, however if you're leaving your car overnight (with temperatures being very cold this year), it's a legitimate worry.
I have had friends cars suffer this problem at Hotham & Buller.
