Yes, I too find gasoline is very effective at removing water, and radiator fluid from motor oil. It also seems to make the dirt fall right out, if there is enough gasoline in the blend. The carbon is the hard thing to get rid of, because its density is so close to the specific gravity of motor...

I am not sure what waste oil that you are dealing with. I find pre-blend WVO benefits by long settling periods, 2 weeks warm works for me. But, WMO does not seem to benefit from long pre-blend settling periods. If you are working with WMO, then blending it with gasoline at 20%, then leaving...

I have been running 20% gasoline to 80 WVO for 7 years, and find it runs quite well. In the winter up to 30% runs better in the cold, but you have to keep in mind that you need to settle your blends for a few weeks, or run them through a centrifuge.

Nice setup. I use 2 smaller 20" Pentek bag filters and a 2" y-trap in series for filtering my waste oil blends with 1" cam lock fittings and hoses on it. I can pump fuel through my bag filters faster than my deuce fuel tank can receive it. However, I too am considering upgrading to 2" cam...

I have been using the Banjo poly quick cam fittings since 2007 for processing gasoline blended waste oil-based fuels, and they work great. I have used them with a wide range of solvents with no problem, other than the standard buna-n seals dry out after a few years, and start to leak. So, I...

That is useful information, Jeepsinker. So, would you happen to know how long you left your samples sitting? Also, did you make a WMO-blend sample with gasoline? Because gasoline is the cheapest solvent around, most waste-oil diesel fuel blenders use gasoline to thin their waste oils with.

Fat sinks in oil, but floats on water.

Jet fuels work best at 40-60% ratio to waste oils, so you should be good to go, but cold weather might pose a starting problem.

I have a mobile fuel making system on the back of my Chevy van with a 6.2L n/a. See photo. I plan to install a larger version of this system onto the rear of my m756a2. The only real difference will be larger tanks for processing and storage. I do not plan to change my filtration system; but I...

Gear oil is the only oil that I have had a great deal of trouble burning, other than heavily burned WMO, but if it was a small percentage, then it would probably be OK. Otherwise, it might need gasoline blended with it at 50%, then you would have to find alcohol-free gasoline to blend with it.

This sounds interesting. Gelled oils, which we tend to call fats, will generally settle to the bottom, so I am not sure what was floating on the top of your tank. How long do you settle your WVO-gasoline blends for? Also, heating a gasoline blend to 150F is a really bad idea, because gasoline...

e85 is about 51-85% ethanol. That high a concentration of ethanol in fuel can corrode aluminum parts, and some elastomers. Old vehicles built before 1996 generally are not alcohol friendly, so that the concentration of alcohol in the fuel blend has to be brought down to below 3%. This...

Any diesel engine should be able to burn your waste turbine oil (WTB), although a turbo charger help a great deal with burning marginal fuels in diesel engines. You may have to add a small amount of gasoline to improve its combustion, but I bet it will not be much more than 5%.

A google search for MIL-PRF-23699 oil says it is a Turbine Oil and it is a 5 mm2/s (5 cSt) synthetic ester oil. It sounds like you just hit the mother load. All I would do with it is run it through a final filter attached to a transfer pump and pump it right in. It might be a little hard to...

Good to read a post from you bobbywalter, on this forum. It seems to be a friendlier place to discuss burning waste oils as fuel, than other forums I have been on.

Correct, because there can be liquids that are also precipitates, such as water, or radiator fluid, or tar, so the sediments need to be separated from the uniform solution that floats on top. There can even be contaminants that float on top, so you have to pay attention to the fuel that you are...

Yes.

Sorry, joshs1ofakindxj, I must have missed your question on this thread. The negative reaction when some WMOs meet some WVOs is a thick, black sludge that melts at about 160F. It will coat the bottom of your fuel tank, and fuel lines all of the way through your injector pump and coke your...

You might be onto something here, because I got so good at removing the carbon from my WMO that it was translucent; however, my injectors still coked, although it took months, instead of days, for them to coke shut. What I found when I pulled my injectors was not black coke on my injector tips...

Yes, for collecting viscous waste oils, a good quality transfer pump works great; however, a pressure tank and a simple vacuum pump will work quite well, by evacuating the tank to a decent vacuum, and inserting your hose into the thick oil, then opening a valve to the tank. It will fill about...
