DATE: Sat, 26 May 2001 06:03:08 GMT ORGANIZATION: BigPond Internet Services (http://www.bigpond.net.au) NEWSGROUPS: aus.cars.offroad Short question : Where can I buy that stuff you add to diesel to make it 'Alpine diesel', or prevent waxing of fuel lines? Long question (more like an essay really!) : I went fishing at Lake Tantangera last night. Before you ask, no, I didn't catch any fish! Tannie is in the heart of the Snowy Mountains. When I got up, which was about 7AM, the thermometer in the car (attached to fridge - two readings, one for inside, one for outside) was showing about -6 degrees. Not exactly warm, but I've been out there when it was colder! By the time I broke camp, it was about 9AM. Had warmed up to -1. I'd had my Hilux idling for about 20 minutes to warm it up. I drove off, and got about 100m, before it started to lose power, engine started to chug and it stopped. It restarted, but was revving very slowly, and would not rev very high. I managed to nurse it along until the revs pickup up to about 1000RPM; then I wound in the hand throttle and popped the bonnet. I'm fairly sure I knew what the problem was - the fuel lines and filter have had the diesel solidify in the cold (aka 'waxing'), preventing fuel delivery to the engine. I pumped the fuel filter plunger repeatedly - this should draw fuel from the tank into the filter right??? (I have an aftermarket Racor filter, and the bowl at the bottom wasn't clear as it usually is!). This seemed to be working - the revs were picking up, but it was blowing a lot of black smoke. I kept on at it, and the engine sprang into life. Stopped pumping the plunger and let it go for a while - it was now revving at 3000. The bowl looked a lot clearer, but not 100%. So I closed the bonnett, and moved off, and it was OK. I haven't actually filled up the Hilux for about 5 or 6 weeks now (benefits of a 130l fuel tank and buying another car!!), and only in the last few weeks has 'Alpine' diesel become available at the servos. This has never happened to my Hilux before; we've done lots of trips into the Vic High Country over winter, but have always refulled at local servos where thay have had their Alpine/Winter diesel available. And now, refer to the 'short question' above! Cheers, Ruley FROM: w.j.markerink@a1.nl (Willem-Jan Markerink) SUBJECT: Re: And speaking of diesel fuel....

You can add up to 15% (old Mercedes recommendation) of gasoline to achieve the same effect as winterizer-products....the only benefit of dedicated fuel-additives is that they restore the lubrication-properties of diesel....but you would be more concerned about that with a modern rotary pump than an old inline pump. Btw, it's also recommended to keep your tank filled up, because near-emtpy tanks can cause condensation, and clog your waterfilter. One of the reasons why the military wants to keep their fueltanks filled up I have been told. (note that it's not the water from the fuel itself that vaporizes and condensates....that would be a closed loop....it's the outside humid air being sucked in as the fuel is drained, and then condensates overnight) (posted & mailed) -- Bye, Willem-Jan Markerink The desire to understand is sometimes far less intelligent than the inability to understand [note: 'a-one' & 'en-el'!] FROM: w.j.markerink@a1.nl (Willem-Jan Markerink) SUBJECT: Re: And speaking of diesel fuel....

I seem to remember my brother telling me that when he was in Antarctica thirty years ago they ran on 100% Aviation Turbine Fuel (a.k.a. kerosene) - and switched the engines off once a week, just long enough to change the oil. These were Detroit Diesels in Nodwell tracked carriers I think. He was out on the ice for up to three months at a time. JD FROM: "Ruley" SUBJECT: Re: And speaking of diesel fuel....

And mixing ANYTHING with diesel fuel probably has legal implications, as diesel is subject to the highest excise of any petroleum fuel, and some of the suggestions have none.

Some of them would only sell me bulk heating oil on the condition that it would not end up my fuel tank (ie they would turn a blind eye). One mentioned some sort of tracer in the heating oil(?). I understand that there's a tax issue here, with some unscrupulous operators adding heating oil to the service station tanks and thus not maying the full amount of tax... something like that, and the tracer shows this up... dunno the full story.

An additive in the fuel is at the heart of the problem, causing blockages in some fuel filters. That results in engines losing power and eventually stopping. Diesel is widely used by trucks, emergency service vehicles, boats and some private cars.Owners of diesel-powered vehicles, boats and machinery have been told to continue using diesel but to seek advice from mechanics at the first signs of rough running, power loss or hard starting. People driving diesel-engined cars have also been cautioned to check fuel filters before starting long trips. NZRC deputy general manager Shaun Dyke told NZPA from the refinery tonight that the imported additive the company began using in late March for winter-grade fuel was from a different supplier from the one used in the past. Mr Dyke said one third of the contaminated 300 million litres was still in circulation "and yes, it's certainly a major problem".
