    Diesel info for cold climates

    I remember last year a lot of discussion about blending diesel suitable for winter/alpine areas.

    I've found a chart in my Mercedes manual that tells how much %age kerosene or petrol to add to diesel at various temperatures. I can scan in the page tonight if anyone would like it for reference.

    It also says, although in more elegant words, to add 30% petrol () to the tank every now and then and flog the engine to buggery to keep the injection system in GC. Naturally I'd discourage this in any radially injected LR.

    By Radially Injected I presume that you mean a Landrover or similar fitted with a rotary injector pump, CAV Rotary Pump comes to mind, fitted to most english diesels of the 50's,60's,70's


    cheers

    Rather than mix your own - why not just buy alpine fuel?

    Rather than use kerro, I'd be inclined to use this, purely for lubricity with a rotary pump http://www.redlineoil.com.au/Uploads...TR%2002_03.pdf

    I have never had a problem with startability in cold weather of any diesel engine I have owned. Cummins NHC & NTC & NTA's used to need a sniff of ether in the cold in Victoria and South Australia and ran ragged for a minute or so until warmed up. Particularly the NTA's and anything that had been modified to get more power. Detroit two strokes always start right up and run well as do Isuzu 4BD1. I have seen lots of antics in the past with cold starting trucks and machinery that had pre-chamber engines. Ether, fires underneath, blow torches, and burning rags held over the air intake to tell of a few necessary tricks.

    I don't know if this is done in Australia but refiners in countries with extreme winters make winter fuels with more wax refined out and more butane bunged in for improved startability.

    mate, where I am it regularly gets to -5 in winter, we've seen -7 a few times and it gets a darn sight colder up Armidale way and we all just use pump fuel too, but maybe we get the same as alpine fuel in winter ?

    I sat in a truck in - 30, no winter fuel was available last stop. every 10-15 klms we slowed to a stop then we cleaned out the blocked filters with a stick as best we could and took off again, 150klm we came to the next servo added 5% petrol. no problems after that.

    but then that would hardly be a problem in aussie

    I spent a little time in the US in a winter and some of the truckers from the snow belt had plumbed a pipe about 1 1/2" - 2" diameter into the exhaust stacks and ran it to blow hot gases onto the bottom of a fuel tank at the outlet fitting. Much like ships run exhaust gases through pipes in the fuel bunkers to liquify the low grade muck they run on. I loved the electric outlets on posts in the parking lots at truck stops, like the speaker stands at drive-in theatres, to plug block heaters into whilst parked.

    I once used to sell a range of earthmoving equipment made in Minnesota and the standard equipment included a 110 volt block heater and lead.

    In Australian colder climates alpine diesel is the norm in winter. You don't have to ask for it and it costs no more - garages change over automatically. I do not know what the trigger point is but I believe in Canberra the change is normally in May.

    The problem is that some city types fill up in Sydney or Melbourne where there is no alpine fuel, drive to the snow, park overnite and wonder why their diesels will not start next morning until it warms up a bit. So in winter always fill up in the mountains before stopping overnight.
