WMO, cold temps and fuel gelling
At what temp should I start worrying about 30% WMO in #2 diesel? Same questions for #1. Any preffered mixes for cold weather and WMO?
The reason I ask is that I'm driving to Montana for Thanksgiving and I plan to run 30 - 50% WMO on the way up and back. Temperatures probably won't be below freezing while I'm on the road, but while I'm up there for a week, there's a good likelyhood of overnight low temps. I'd rather not come out and find my truck won't start because of frozen fuel.

You are not going to like my answer, but I run up to 30% gasoline in the winter.
I have done it with and without WMO and never had a problem. I will start running it when the temp gets below 20 degrees and I like to stay around 20% gas.

BADME,
Does the gasoline help at all with preventing smoke? Also are you talking about running 20% of total mixture or 20% of the amount of WMO? The reason I ask is because I just made a batch of WMO 110 gallons and 10 gallons of gas and the rest 150 gallons of #2. I am having a lot of smoke though and I need to try to reduce it. Any help would be appreciated.

I never had a problem with smoking. I run 50/50 on the wmo and #2. In the winter I will add 10 gallons of gas to 50 gallons of 50/50 mix. Looking at your mix ratio it should burn fine without a lot of smoke. Are you sure that your injectors are not leaking?

I don't know what you're burning your mixture in, but I would not burn 20% gasoline in any diesel I own including a 1965 Case 730 tractor!! You're asking for trouble. Even back in the '80's when VW suggested diluting their fuel with gas in the winter months the max was 10%, and many said that would cause grief with injectors and pumps.

I am either going to figure out the proper mixture or blow it up. I need to get the stuff out of there that is in the tank, it is smoking so bad I am sure I am going to get pulled over soon. Once that stuff is out then I will restart on the mixture.

I know have over 1300 miles on my mix and other than a lot of smoke for a period during the driving I have had no problems. The mix may not have been mixed thoughly enough but it has seriously quieted down the motor and I can feel more power as well. I will keep you all posted but I did add some gas to the mix in the in bed tank, another 10 gallons, and it seemed to clean up the heavy smoke. BADME thanks again for the help.

gasoline will pre-ignite and has less lubricating value so it could be dangerous. With all the oil in the mix, who knows. Really with diesel you want the ignition temperature close to spec. for the lubrication value you can add something to help with. If you can test your mixture somehow to verify flash point, youd have a better way to tell if its safe.
pre-ignition can pop gaskets and damage crank bearings
