What do I do after biodiesel gelling?

[Mr. C]

What is a good Biodiesel to Winterized Diesel # 2 ratio to prevent jelling in temps as low as 5 degrees F.

Ed

It all depends on the feed stock and if there is any water content in the finished product. Your best bet is to mix a few freezer sample jars and test for yourself, it really can vary that much.

hello jgk

lets do some math



100,000 miles of wear in a few miles ok

I have been running rug in my truck for 12,000 miles so your telling me the wear on the engine is like running it for what????? a few is like 3 right so 12,000 divied by 3 is 4,000 then times buy 100,000 right thats 400,000,000 miles of wear right ?????

but I have the oil report that shows no wear out of normal they must be wrong , I think not.



if you have a problem with putting gas in your diesel then you need to say so but dont start blowing smoke about how bad it is talk to any trucker over the age of 60 and ask them what they did when it got really cold to keep the engine from gelling up. YOU MIGHT JUST LEARN SOMETHING NEW.



if jet A is ok what about jet B ???



oh buy the way you should love the ulsd it's great if you run a diesel shop

I have been in diesels since the mid fifties, I can honestly say that gasoline in diesel fuel is a giant mistake, a rumor started by some misinformed truckers does not make it right. Being in the petroleum industry for the last thirty years I have the word from petroleum engineers/chemicals that say all you need is ten gallons of gasoline to screw up a thousand gallons of diesel! It lowers your flashpoint to atmospheric, which in turn will detonate your engine in a short period of time. If you have driven any gasoline in your diesel for any period of time, and gotten away with it, consider yourself very lucky!The normal flashpoint for #2 diesel is 122 F to 180 F, so you figure it out. . #1 diesel-aviation grade kerosene runs at 100 to 140. Gasoline is -50 or atmospheric... ...



Just change your fuel filter, top your tank off with #1 and drive it out.



Oh, I almost forgot, ULSD has the same make up as LSD, same lubricity, same flash, same pour point, and same freeze point, so? The only thing missing is the sulfur. .



In case you think I am some young pup, I drove, owned and operated for over fifteen years, my father drove, owned and operated for over thirty years (back into the gassers, chain drive, and solid rubber tires). I have seen some expensive equipment sitting on the side of the road because of gasoline added to the tanks... My last twenty plus years, I have been working in refined fuels division of major oil company...



Bio is great in summer months, but when temps start to dip below freezing it is time to start using your old petroleum fuels again. #1 has the same lubricity as #2, it does cut back on your mileage due to cetane ratings and flashpoint. If you must use bio in the winter, I would go with a fifty fifty mix with #1. This should bring you down to -20, same as #2 petroleum. #1 is more expensive than #2, so if you decide on #2 mix, go 75% - 25%. Then use some flow improver also, such as staydyne, or Amsoil cetane boost, or flow improver. Hope this helps.



Oh, you can get an idea of cloud point and pour points of diesel by just putting it in the freezer. But, it is not an accurate method. The ASTM method involves dry ice, acohol, stirrers, thermometers, and three pyrex glass containers. You have to watch and stir the product as the temps lower, when it clouds, you have your cloud point, when it stiffens, you have your freeze point. Most of your #1 aviation grade kerosenes have a freeze point of -30 to -50 ...
