Does it burn cleaner than regular diesel?

In the end it doesn't matter because what the greenies REALLY want is a cap on the human population of say, 50,000 people world wide.

I'm curious. My wife's boss burn this stuff. Seems like alot of work straining out the crap thats in it. Or growing fields of soybeans, how many million acres have to be grown to make a difference in fossil fuel use? I don't know seems like hype up BS to me.

Back to my original question does it burn cleaner?

Check out this site.  It has all the info you could possibly want on this topic.

I will try to attempt to remember to ask my sister; her son makes biodiesel for the family. His is a real going concern, too! He has more fuel than they can burn in their vehicles now!

He has every restaurant in town saving their cooking oil for him to collect.

True biodiesel shouldn't smell like french fries.  Sure he's not running VMO?

Yes, generally.  The problems that were related to me had to do with the biodiesel having much greater detergency and cleaning the heck out of the whole fuel system and completely packing up the filters.  Of course, this was with people who were always looking for an angle and didn't take great care of their vehicles to begin with.

Most manufacturers (globally) are cool with B-5 –– or 5% biodiesel mixed with normal #2 or the local equivalent.  As standards improve for biodiesel (how acid it can be and so forth), that will probably shift to B-20 being OK with almost everyone, as opposed to only a few manufacturers now.

What is interesting (or should be) is running 5-7% waste lube oil in diesel.  I know a fellow who was on the fence about harvesting grease and making his own because of some concerns about methanol (really underappreciated as a poison) who I helped to make a solar-pumped biodiesel mini-refinery.  He found that adding 5% waste lube oil gave him close to 10% better mileage, so that returned him to where he was (he had had a 10% decline in mileage with the biodiesel).

His methanol trick was pulling a vacuum at 160 degrees or so to degas.  The amount was reduced so much it would be almost impossible to have any ill effects.

Yes.  It is an Oxygenated fuel and burns cleaner.  The emissions contain much less unburned.  Biodiesel is also a natural lubricant and cleaner which extends the life of your engine eliminating the need for sulphur in the fuel.  France has 0 sulphur diesel and mandates 5% biodiesel.  THe only problem is that it will clean your fuel tank and all the dirt from the diesel thats been sitting in there will clog your filters.  Its pretty easy to make if you have the space/ equipment.  Ive made a couple litres in my parents garage and run it in my Jeep CRD.  I buy it whenever I can find it.

Okay, she got back to me. She says his truck and their other vehicles DEFINATELY run cleaner!

No, bio smells like french fries or a donut shop too.  You could definitely smell when I would run bio in my PSD.

We are (my Company) purchasing a New Holland tractor that will run exclusively on Bio-diesel. New Holland is one of the few/only companies that has certified their engines for B100. Our local plant that we will purchase from meets the bio-diesel standards set by New Holland and make a lot of their bio diesel from animal renderings.
