Diesels in sub-zero temperatures

Last winter in June I was at Perisher Valley when the temperatures overnight dropped to minus 15 degrees. I didn't try to start it until 10 am, and by that time it was sunny and heat was coming off the bitumen surface

The engine just would't start, even though I'd filled up with Alpine Diesel at Cooma.

What tips are there for coping with really cold weather with Diesels - if I'd been camped in an isolated area, it could have been a serious problem.

I suspect you would be the victim of your fuel not being of a high enough percentage
of "Alpine" diesel. The additive was probably diluted by the fuel remaining in the tank.
You may have been sold fuel that wasnt full spec either as retailers are unlikely to use
use all non additive fuel before filling with Alpine. Another possibilty is that your pre
heating system is not functioning correctly......oldbaz.

I always keep a sample of Fuel I buy - the sample jar had visible crystals in it.

I tested it when I got home - it went cloudy at Minus 7 degrees, which explains why it wouldn't start.

Australian Pajeros don't have a Fuel Preheating system - even though some of the wiring is there.

although that wouldn't have helped the cold fuel already in the filter.

Well that depends, did it not start because the fuel had gelled or because the glow plugs weren't working and the compression was low?

If you go to youtube and search for cold start, you'll see ancient volvos and VWs starting first go in -30 conditions, without block heaters.

Of course, you could carry a can of 'start ya bastard' aka aerostart but that depends on what the problem actually is.

There are electrically heated fuel filters and electric water heaters that go inline just after the water pump but they usually require mains power.

Having spent 20 years up and back to the mountains in snow season we were only caught out once with iced up Diesel. Used Alpine mix all the time but usually added 1lt of Kerosene as well to every tank. The machine operators on the mountain suggested this.

agree TTD1,

kero is what's needed down below 10 degrees minus.
Either that, or even a few litres of petrol.
Used to do this in Europe with a previously owned Golf GTD back in the 80ties.
The drawback of the petrol is it doesn't lubricate the injection pump, while kero does have some lubricating properties.
I remember cruising past stranded trucks on the Autobahn at minus 32 with some good petrol/diesel mix sloshing around in the tank...

cheers, Peter

Battery Value,
I used to put a litre of kero to a full tank in the old 4.2lt patrol tank which from memory was 90ltrs so about 90 to one mix and just stoped the mix from crystallizing.

Yes, adding Kero to Alpine Diesel is what I'm looking at doing if it looks like going below Minus 5.

BP recommend adding 1 L Kero per 25 L Summer Diesel to convert it to Winter Diesel.

great idea. When it got down to -15 at the ski fields I made sure my car was parked where it got the morning sun cause it was a pain to start but I just had standard diesel. The doors were pretty hard to open cause the grease on the hinges was freezing, I think. I've got a Hyundai Galloper Turbo. I'lkl try to take a bottle of kero next time- just pour it in the fuel tank?

You need to pour the Kero into the tank some distance before you park, to give it time to mix with the fuel in the tank and to go through the whole fuel system.

it's usually -5 to -15 at night in winter where I work. Should I put a litre of kero in the tank on each filliup? Or isn't it too good for the motor?

BP on their website had reference to adding Kero to Diesel in a particular ratio.
I think you can find this on one of their .pdf files on the right of th is link

BP Diesel page

cheers hope that helps.

I went to the National Parks Depot and NSW Fire Brigade station, to ask for tips from locals when they had trouble at very low temperatures - but got blank looks.

The NRMA guy happened to be there - with 20 litres of hot water just in case anyone with a diesel had problems.

I put a towel over the filter and fuel plumbing near the engine, to hold the hot water as long as possible.

I waited five minutes and then it started normally.

Yep SAB (Special Antarctic Blend) is what we used at Casey Station (Kero & Diesel).

Ran utes, CATs, etc and no problems.

BP blend if I remember correctly.

Cheers
