In another hand, in Mauritius there is a guy that swear that by putting some in your tank and drive like you stole it it'll clean the engine. Lots of smoke and spatter. But I'll be a wee worry there...
I read somewhere that parafin as no lubricacity and if your pump is "oiled" with the fuel you will be in trouble. Might seize up...

I had a little bit of gasoline residue in my tank when I filled it up with diesel and my engine ran like crap for that first tank.
So from that, I assume it doesn't take much gasoline to make the engine run terrible.

I haven't tried paraffin but I did convert my truck from gas to diesel.

I remember seeing something in the manual about the acceptable percentage of kerosene you could mix in, but afaik gasoline causes some nasty pre-ignition.

Yes in the manual it says it is acceptable to put one gallon of kerosene to a full tank of diesel in the winter.
Ive used kerosene at higher precentages than that, but with gasoline the most i will use is one gallon to one full tank, and not very often at that.
But i have had no bad experiances so far, on 3 different cars.

Can gasoline cause pre-ignition in a diesel engine? the fuel is injected at the moment it is supposed to ignite so how can it pre-ignite? seams impossible to me unless the flamefront is spreading at a much faster rate when gasoline is present. But if it is so, adjusting the pump timing should fix the problem.

Gas even explodes too fast when thinned out 1 gallon to a 20somthing gallon tank of ULSD? and for lubrication, if not wvo, how about adding some biodiesel to help with the lubrication?
Why not just use biodiesel alltogether one might say.. Well sometimes it may not be available, or available in quantities or may be too expensive blahblah.

Hey FI (and others) what does kerosene do the engine (mixed in small ratios). I know lots of people in rural NY (I know under-educated rednecks--(no offense)) that use some kerosene in the winter to thin the fuel and help with anti-jelling. Farmers in tractors as well as people with diesel pickups.
IMPORTANT ?-What do you guys in the colder climes find to be your favorite anti-gel? I started mine down to -27 F actual temp with anti-gel and some kerosene.
Does anyone know what the guys at Arctic Trucks use for a fuel mixture?

Kero acts as an anti-gell agent, and iirc winter mix has a small bit of it added anyways. You can run an engine on it, you just have a slight reduction in overall power because of the lesser energy density of kerosene.

There is no need to add anything to winterized diesel unless you're transporting it multiple states north into a much colder climate.

Additional lubrication is required for any significant percentage of kero in the tank.

What temp have you guys been down to in a w123.
When I ran at -27F I let the car get up to full temp. And about 7 minutes later had things freeze up. It took me about 3-4 stops on the way home (28 mi) to get home.
So... obviously I'm thinking ?? a radiator 'skirt' is in order???
Any suggestions?
I'm not even sure what the radiator covers are called, but has anyone found on on a w123???
Again any help/info would be great. We sometimes see -40F or so around here.

(10-16-2010, 03:18 AM)Olivier Why was it a bad habit?
The potential to overheat if caught in traffic, left idling or if not watching coolant temperatures on warm days.
The fan takes so little power/economy that its not worth the hassle and risk.
On really sub-zero days (-15*f or colder) I cover the upper half of the radiator and pull it as soon as the weather breaks.

Gasoline will wash away lubrication in the injection system but that can be solved by adding some 2 stroke oil.
Gasoline will lower the cetane number(the fuels ability to self ignite). This will lead to more difficult cold start, but more important, the ignition delay will be longer and when it ignite, there will be more fuel in the combustion chamber giving a less controlled higher pressure(sounds like knocking).
The combustion temperature will be higher and that can cause serious problems for the nozzles. melt down or clogging of the tip and also carbon buildup internally that will wear down the nozzle.
So my conclusion is to avoid gasoline mix in the diesel fuel. Some people claim that it can help to clean up the head and piston from carbon buildup(because the higher temperature) but probably it won`t.
If you accidentally fill some gasoline in your diesel car and have mechanical IP, you will most likely be OK if you are able to lower the gasoline percentage below 20%. But if you have a newer engine(common rail) you will have a serious problem. You should not run the engine at all, and need to drain the whole fuel system.

02-09-2011, 07:55 PM #26On my '85 Peugeot TD, I made a grill cover out of masonite, and cut two 4 inch diameter holes in it. It's held on by a brass bolt/wing nut washer combo. I keep it on all winter once the average daily temp goes below 0 c, and block the holes if I'm just driving around the city, or the ave daily temp goes below -10c. The motor comes to normal op temp much quicker, my mpg goes up and I get good heat in the cabin compared to not using a grill cover.
