Says in my 1985 W123 300TD handbook that up to 25% petrol (Gasoline) can be used in very cold weather... The use of 'Kero' in Europe and UK as a road-fuel is illegal....

I have to wonder if a 617 would start better in colder climates if MB had used a gear reduction starter like pretty much every other compact diesel manufacturer instead of the giant direct drive. It doesn't help at all that they have that miniature flywheel, so there's even less torque that the starter can actually apply to the crank. Once I get mine installed I'll have to try it with a stock Ford starter and then a gear reduction one to see how much quicker it'll whip it over. It'll be a bit off of a comparison, though, as my flywheel is much bigger.

In a previous thread (maybe about my 86) I tried to 'prove' that they had said it was okay to add unleaded gas to the fuel in the winter, and unfortunately I ended up eating my words; went back to check the book and kerosene is the only additive they said I could use. However... people have been mixing a small amount of gas into diesel for farm equipment for years and years, so I'd still do it without hesitation.

mixing gasoline or kerosene into your fuel is only needed if you have summer blend fuel in your tank, and it's below 0°F outside. your fuel will gel. it will not help spinning over the motor one bit. if the motor is spinning fine, and your primary filter is full of wax, then mixing in a proper fuel thinner is best, followed by kerosene, then the gasoline as a last resort in very small amounts, (10% MAX)

When I lived in Germany there were some gas stations that sold 'cold weather' diesel fuel that contained a small amount of clear kerosene but it was legal and road taxed.

also note, that if it's VERY cold, as in below -25F outside, it's going to be difficult to run any car without a heater plugged into the block and the fuel tank. no amount of gasoline or kerosene is going to help. heat is needed.

Here you go.....
Near the bottom of this thread, there is a pic of page 127 of a 1991 MB 190D handbook... http://www.vegetableoildiesel.co.uk/forum/viewthread.php?tid=8764&page=1#pid221461 Under the % chart and temperatures, it says--'Kerosine or a Maximum Proportion Of 20% Unleaded, Regular Grade Fuel Hey, Its prolly a 'Territories' thing, One thing is fine in one country but not in another..... I dunno, All I know is its been done here for a Long Time! True, no amount of gas in diesel will help spin an engine over, But IF the thing spins fine on starter and the fuel aint waxed and plugging the filters, just a little gas can sure help it fire up if its normally reluctant without! These cars (W123/4) are getting pretty long in the tooth now, Compression aint as good as it once was in a lot of cases, so they need every bit of help they can get, couple of % gas in your std. diesel could make the difference on a cold morning between starting or not--Certainly isnt gonna Harm it....! Currently I'm doing some experiments with my Aixam... (Aixam, = Bit like a Non Trendy 'Smart-Car' Tiny belt-driven automatic CVT 500cc twin-pot diesel car made in France, does up to 100MPG) This one is run on VO...( Yup, I know--heard it all before, so dont bother!)  Anyway, Starting a twin-pot Kubota IDi Diesel on Straight Fresh Veg (rape I think....) at 100% from stone-cold (around 1-2 deg C) is very nearly Impossible. Add around 2% Petrol/Gasoline and she'll fire up, but isnt what I would call great, gotta keep the revs up for a few mins. or it'll cut out. At 5% Petrol, it fires up and runs just like on std. diesel fuel--Except Infinately Quieter....Aixam is unbelieveably noisy anyway.... The gas is acting like a combustion initiator for the cold fuel in this case....
