is some kerosene ok for winter
 

i was running wvo in my $500.00 78 300d. It went kaput for other reasons. My 85td is too nice to take a chance with wvo though, So i started making biodiesel. Seems pretty well accepted that it is not harmful. Anyway the gel point seems to be higher. Some charts I have seen say that cutting my b100 with 20% kerosene will keep me good to 16F, which should be fine for central virginia. Is this ok ?

I don't know about mixing with WVO, but the 85 300TD owners manual says you can run up to 50% kero/diesel mix.

I think he said mixing it with BioD- and that is just fine.

putting some bio and/or blended fuel in a small glass jar outside the kitchen window will allow you to see if you are going to have a problem each morning.

Putting some in the freezer and checking the temp every 15 minutes until it gels is good info too.

just dont run it straight- there is not enough lubrication in it, AFAIK...

According to the real live MB manual
 

"WARNING! Under no circumstances should gasoline be added to diesel fuel.
Use winterized No. 1 diesel.

If not available
14 F - 32 F == 70% Diesel fuel + 30% Kerosene.

Below 14 F == 50% Diesel fuel + 50% Kerosene.

Even in extreme climatic conditions the maximum ratio should not exceed 50%.

Adding kerosene to No. 1 diesel fuel is not recommended even at low temperatures."

I think with the 616 617s the owners manual says up to 20% (?) not sure the exact %.

Bio lubricates more than petroleum diesel, so anything up to 50-50 Bio/Kero should be safe if a 50-50 D2/Kero is fine.
