rocky Posted December 31, 2008 Posted December 31, 2008 Hi, are there any additives that i can use to stop diesel waxing. I had left my 300tdi disco for a few days without starting it (-10 most nights), started today without too much winding. Drove to the cairngorms--about 30 miles--and left it about 3 hours (-14) while we went for a walk. It started ok but with the pump making a weird noise. After a couple of miles it lost power and I had to drive home at 20 miles per hour. Made it to within 5 miles of home where it gave up altogether, fortunately stopped outside a garage. The mechanic took it inside to thaw out and also changed the fuel filter. No probs the rest of the journey. The mechanic did say that he had been dragging diesels in all day for the same problem. I thought fuel companies put anti-waxing agents in their derv. Anyway I have to use the vehicle in very cold conditions so I was wondering if there was anything I could add to the fuel to stop this happening again. Regards, rocky Quote
pinny Posted December 31, 2008 Posted December 31, 2008 when you say changed the fuel filter did he clean out the sediment filter under neath next to the fuel tank when mine started losing power this sediment trap was full of a egg yolk substance similar to a liquid wax not sure of the temp diesel waxes at chris.

pinny Posted December 31, 2008 Posted December 31, 2008 No he didn't, I'll have to have a look after I've sobered up tomorrow. Rocky no probs mate mine was 3/4 full of egg yolk which was floating and blocking the diesel supply ,chris Quote
nicedayforit Posted December 31, 2008 Posted December 31, 2008 no probs mate mine was 3/4 full of egg yolk which was floating and blocking the diesel supply ,chris 5% kerosene added to the diesel works but is illegal on the road. To be road legal try this lot http://www.kamco.co.uk/diesel.htm Quote
white90 Posted December 31, 2008 Posted December 31, 2008 Add some unleaded, that is what I used on mine when it was very cold and the Veg oil was waxing. Quote
Steve Hiatt Posted December 31, 2008 Posted December 31, 2008 I would say there was a good chance it was water in your filter freezing rather than waxing, it will be interesting to see if the problem persists now you have a new filter. Quote

Winter diesel is only protected to -12C. Diesel waxing is a fairly common problem in extreme cold in the north of Scotland, if you are lucky most of the wax collects in the fuel filter. Quote
rocky Posted January 1, 2009 Author Posted January 1, 2009 Hi, thanks for the replies. Haven't started it up today cos it has been raining on top of the ice and I now have a disco shaped ice block. Rocky Quote
Steve Hiatt Posted January 1, 2009 Posted January 1, 2009 DERV to -15 deg, Red/gas oil to -12 deg, minimum winter standard. Quote
nicedayforit Posted January 1, 2009 Posted January 1, 2009 DERV to -15 deg, Red/gas oil to -12 deg, minimum winter standard. Quite correct, misread Quote
Landowner Posted January 1, 2009 Posted January 1, 2009 Dont forget the wind chill factor, if fuel lines and filter exposed to cold air stream then fuel will thicken very easily in the frosty conditions. I ran my truck with 5 galls parraffin added to 70 galls derv in the very cold winter of I think 1982/3 not sure. Down to -20 at night in Scotland and never had a problem. Many trucks froze up that winter but mine kept going. Kept the speed down as well when it was very bad. Still owe the revenue for the duty on the parraffin but I'm working on it. Quote
TheRecklessEngineer Posted January 1, 2009 Posted January 1, 2009 Petrol used to be the standard here and still is in russia and china... 5% should do it. Quote
