This is a good point; however, understanding the law is important for anyone who is making recycled fuels. Last year I investigated the laws surrounding alternative fuel making. It turns out there is an exemption amount. I think it is 250 gallons per quarter anyone can make and burn without...

There is no reason why creosote will not work as a fuel source; however, creosote tends to be the bottom end of a distillation unit, so it tends to be full of coke. Coke in your fuel means coke in your engine. Creosote also tends to be predominantly aromatic benzene rings, which stink and...

Does anyone know where I can buy filter screens like this?

Good point, I use waste stale gas from small engine repair shops, or waste paint thinner from body shops, when I can get it; otherwise I buy gasoline to blend with my waste oils. However, I thought you were speaking of how much you should have to pay for waste oils, not for the final product.

I have never had to pay for recycling waste oils and solvents. In fact I get more waste oils of all kinds than I can use. However, if i ever get to the point that I cannot meet my fuel needs, then I would consider 25% of pump price per gallon for diesel fuel acceptable. But, long before that I...

Correct The reaction between WMO and biodiesel has nothing to do with how good your biodiesel is. It has more to do with how bad the WMO is; because heavily burned and overused WMO has lacquers in it, which are high melting point polymerized hydrocarbons, which are not as soluble in vegetable...

It is possible that the biodiesel will react negatively with the WMO, so if you are going to thin the WMO with biodiesel, then you will wont to leave the blend to settle for about a week before filtering it, to allow any incompatible components to precipitate out of solution and settle to the...

I have run stale gasoline blended with WVO off and on for a few years with no trouble. I get the stale gasoline from small engine and motorcycle repair shops.

Thanks, Ford Mechanic, when I first read this thread i did not give the gasoline content a question, other than to find it remarkable that a diesel engine would run on 60% diesel and 40% gasoline. However, on second thought, back when the multi-fuel engine was developed gasoline did not have...

Oh, yeah. It is on the shopping list.

Yes, distillation is a lot of expense, time and money; and it is dangerous, but for some it might be the only way to cut the fuel bill.

You can find all kinds of information about my WMO distillation pyrolysis system here Pyrolysis of Hydrocarbons

I process 5-gallon batches of WMO, to get 4.5 gallons of distillate. It takes 1500watts, and 4 hours at 800F.

Thanks for the link to my forum. If you want to run WMO, then you might want to look at this section of the Beyond Biodiesel forum Making Black Diesel (WMO) Your plan of starting with 10% WMO seems like a good plan. I started at 80% blended, settled, filtered and centrifuged WMO and worked my...

It does not mater where your WMO came from, you can burn it as fuel. The big problem with WMO is it can have a lot of dissolved solids and free carbon that can result in coking in your engine. For some reason turbocharged engines have less coking issues when burning WMO. So, if your 6.2L has...

Gasoline will not "eat" any seals in a diesel engine; however, the alcohol that is commonly added to gasoline at about 10% will. Nonetheless, if gasoline content in a waste oil blend is at or below 30%, then all of the seals ever used in a diesel engine will not be affected by the alcohol in...

The premise that has been behind my blending experiments for the last 7 years is, if it remains in solution for at least a week, then the solution is likely to run on my engine without problems. However, as budman67 mentioned above, a temperature drop could cause the precipitation of fat out of...

This is what I do, except I use an old compressor tank, not a barrel, for pressurizing my waste oil blend to push it through several filters. I also settle all of my blends for at least a week before filtering.

Essentially my setup is the same as above, but I do not have tanks or drums in between each stage of filtering. I have the stages, and I pump from a compressor tank, which can handle the pressure, then through several stages of filters. My setup is described here...

Thanks, it is very useful to know that running gasoline in your blends tends to cool your engine slightly. I had guessed so, because gasoline has less BTUs per unit volume than diesel fuel, but WMO has more BTUs per unit volume than D2, so I figured the blend would result in roughly the same...
