Well, here is the skinny on this stuff after 14 or 15 months of use. I've been using it in place of diesel. I start on it and do my local driving on the stuff. Some of what I get has ink and some is clear. I let the inky stuff settle for a while then siphon off the top. The inky stuff smells a little but not severe. The clear smells like diesel without the perfume. Both truck and mercedes run great on the stuff but mercedes is a little noisier at idle. Probably would settle down a bit if injection timing was adjusted to compensate for burn rate. The density of this stuff is about 0.71 and diesel is about 0.77 to 0.80. EGTs are great except when going up a hill while pulling a load. In those conditions EGTs ran a bit higher so I let up on the pedal where I could. This stuff lacks lubricity though. I ran it in the mercedes for about 2 months and almost 200 gallons without any ill effects to the car. The truck however, needs an injection pump. I've determined my injection pump has the worn rotor head issue. In the chemical's defense, I have also run high concentrations of wmo through the truck for almost 3 years. Supplementing this stuff with b100 would probably take care of lubricity issues.
Summary, I really like this stuff and will continue to use it. Problem is the line of equipment that this stuff comes from is not common in it's industry. Also, later generations of the equipment have a recycling unit built in so output has been cut down to a little less than 50%.
Still, some stuff I get for free, can use in a solvent tank then for fuel is just what I like. Unfortunately there isn't alot of this to go around.
Oh, I use 15 gallon plastic barrels with bungs for collecting this stuff. The white rubber gasket the bungs use get soft and swell up but return to normal shape after you remove them.
